Session 9: Emerging and Future Technologies

“You see things; and you say, Why? But I dream things that never were; and I say “Why not?” –George Bernard Shaw

Brief Overview of the class:
We were shown plenty of wonderful videos during class today. Among them was claytronics and plastic electronics. Thinking back to the quotes that were shared in class, when presented with these technologies we should ask ‘Why not?’ Claytronics stand to make product presentations completely different. People would be able to shape the product, hold it and even edit on the spot! This form of interaction would have great implications especially in education. Plastic electronics are a potentially disruptive technology that would threaten to displace silicon technology. Flexible computers and cheaper access to the internet would allow greater global connectivity. We could see the global education and economic gaps potentially closed through this technology.

The next thing we went through in class was the drivers of emerging and future technology. The drivers of emerging and future technologies are ones where we begin to see things differently. Is there another way to fix people’s problems? Have new discoveries allowed us to see things in a new light? Do people really know what they want – if not we can step in and help them out. Changing needs through mass media and advertising? (we can help to shape the need for better products through advertising. The smart 4 (people, ideas, money along with alliances and partnerships) also come up with great ideas although like most fantastic combinations, these are rare. From here we can see that for new ideas to emerge, new perspectives and new insights are needed. New knowledge brings about new understanding. Perhaps when we are able to identify some of this would we be probably able to foresee future technologies?

Interesting Observation:
We’ve come to a point in time when innovation is less so about new discoveries but more on the combinations and permutations of technologies. Biotechnologies seek to fuse genetic modification with other technologies such as medicine, energy and even construction. Nanotechnologies seek to create little robots and combinations of atoms for construction purposes as well as for surveillance. GRID computing (Cloud computing), computer-based simulation technologies and knowledge management technologies were the other topics we covered. Sylvester brought up the combo of cloud computing, medicine and computer gaming which allowed gamers to aid in HIV research giving us yet another good example of converging technology.

Key Takeaway Points:
Innovation distinguishes the leader from the follower – Steve Jobs.

When we innovate, we will be able to see and do things differently. Once we start doing things in greater and better ways would people see the value in how we get things done. When this happens, the people would begin following what we’re doing. The sad hero Nikola Tesla was a great innovator but due to circumstances, the fruits of his works were not fully realized. Which goes to show that some innovators do become leaders, but some are more effective than others.

The way forward is through combinations of current technologies. I won’t need to provide anymore examples as I have covered a couple of them above. Just like good art is a combination of styles that work to create something fantastic, great new technologies are the fruits of combining and applying new insights gleaned from other fields of technology. We have come to a point where our technological palettes can give rise to an almost infinite number of new technological possibilities. Fascinating times are to come.

Ratings for the Class:

Today’s class felt quite alive today and I gained quite a number of new insights from this class. With that, I give this class a 9/10.

Session 8: Energy and World Change: Past, Present and Future

Energy and World Change: Past, Present and Future


Human beings have always needed energy. From energy derived from burning wood for fires to the energy that powers the computers we type on, energy has been changing.
  
We are coming to a revolutionary point in our existence. Most of us are no longer ignorant, intentional or otherwise to the dangers that come from our current energy consumption habits. Countries like China are turning towards green energy alternatives and Germany is already blazing a trail in renewable energy for the world to follow. A future where our energy patterns are sustainable is within our grasp! All the world needs to do now work towards it.

However, why are we so slow in the widespread implementation of all of this? Let’s take a look at some of the barriers to renewable energy.

Extra Reading:
Obstacles to Renewable Energy and Energy Efficiency:

This article was written for the Yale School of Forestry and Environmental Studies and was written by Richard L. Kauffman, CEO of Good Energies. In this blog post, I’ll be talking about the parts I find most interesting.

“The problem isn’t energy.” In this section, attention is brought to the fact that most US universities actually have the technology to create efficient renewable energy systems. However, most of these technologies are seeing use in places such as Europe. This is because renewable technology is seeing more promotion in Europe than in the US

“We’ve got the innovation deployment cart and horse backwards” Here, Kauffman states that most of us are waiting for than one miraculous breakthrough where the innovation in renewable energy makes it cost about as much or hopefully less than conventional sources of energy. Such a breakthrough truly would be miraculous but like most miracles, this may not happen anytime soon. In Europe, markets and incentives had been established to bring in industrial players, namely Siemens and General Electric to enter their wind energy markets with “good-enough” technology. Eventually these companies were able to innovate and create larger windmills at lower costs. Bring the technology in first and let innovation take its natural costs seems to be the solution here.

The playing field is not level. Among the notable barriers to entry for renewable energy is that it is more expensive than conventional sources. This is reinforced by the fact that some countries subsidise fossil fuels. If the externalities of fossil fuel burning are internalized (such as using carbon taxes) perhaps a fairer playing field would be established?

The last point I’ll cover from his article is “We don’t have the infrastructure”. I would say that this point tangoes with the “we’ve got the innovation and deployment cart and horse backwards” quite well. Without an adequate infrastructure, a country cannot utilize all of its geographical advantages. Areas with high wind speeds can’t channel their energy to those who need it and the same can be said for solar energy. If this isn’t in place than we can’t really implement policies to incentivize using renewable energy.

Key Takeaway points (from the lesson as well):
From what we can gather from most of the barriers above, every country most understand what is the main priority here. What is important is that countries around the world begin implementing clean technology as soon as they can. Like most industry beginnings, we have to start small. A market must be formed and nurtured. Once players begin serving that market, innovation, including increased efficiency and lower costs, would come naturally! Once the success and the low risk of such an industry is established, many other positive developments would follow.

Comparative studies are vital. In class, Prof showed us an interesting slide which compared the returns of using 1 square (kilometre) of land for biomass, wind farming and solar energy. Based on that study, solar energy trumped the other two in terms of returns for every square (kilometre) of land. Studies like this help to shape people’s perspectives and perceptions towards technology and can even help lay people (like me) truly appreciate the technology for what it can give.

Based on some of my readings, while gaining a sustainable source of energy is absolutely necessary, attention should also be placed on the efficient use of energy in general. Many studies have been conducted to show that energy inefficiency exists in many forms. From the loss of energy from conversion of its raw state to electricity, transmission and heating/ cooling and lighting the buildings, all these contribute to wasted energy. We can’t really complain that some renewable energies can’t provide enough for our consumption, we don’t really take steps to consume energy efficiently.

Ratings for the class:

Another consistent class for this week. Informative and fast paced without a dull moment in sight. 9/10 from me.

Topical Review Paper Draft Submission



Nuclear Bombs and Nuclear Energy
Executive Summary:
Nuclear technology, especially those involving nuclear weaponry and nuclear energy, has always been a highly contentious subject. This paper will look at some of the biggest moments of nuclear technology so far. Historical events will be looked into to comprehend the maintainence of usage of nuclear weapons today. Contemporary developments such as recent disasters and news will be covered to better understand the nature of nuclear energy. Overall, this paper seeks a balanced perspective on the continued use of both nuclear weaponry and nuclear power in today’s society.

Why I chose this topic.

There was recently a lot of ruckus created when North Korea was initially testing its nuclear weapons. The South Koreans were worried and the United States of America was putting pressure on the People’s Republic of China and the people in general were enjoying an international drama unfolding. What makes nuclear weapons so desirable? Are they really that much of a trump card that it allows people to enter some sort of exclusive Nuclear Club? One of the key points of this paper is to look at the global implications of nuclear weapons.

Fukushima and Chernobyl are two grim reminders of the potential disasters waiting to happen should nuclear power plants face problems. Defenders of nuclear power report that health hazards are not really linked to these incidents but can we trust them if they clearly have a stake in this industry? In this paper we are also briefly going to look at the bright and dark sides of nuclear power. The paper will not touch lightly on some of the historical events centered around nuclear developments and seeks to evaluate their effects on the past and what they hold for the future.

Introduction:
For a matter to be considered world-changing it must have been disruptive to a certain industry or a way mankind gets something done. The most notable disruption in history brought about by the discovery of nuclear power would be its application in nuclear warfare. In this section of the paper, the author will be focusing solely on nuclear bombs for past effects and nuclear energy for present day applications.

Historical Perspective:
Nuclear power is derived from the energy released from splitting the atoms of certain elements. Initial research on nuclear power was centered around creating nuclear bombs during World War II before research focused on using nuclear power to provide energy for the country. Nobody would forget the devastation that the two nuclear bombs: Fat Man and Little Boy on Hiroshima and Nagasaki near the end of World War II. Among the notable nuclear-armed political powers today are the United States of America, Russia and China. Submarines and aircraft carriers also run on nuclear power from on board nuclear generators.


Warfare:
Scientists in the 1930’s discovered nuclear fission and learned of the vast amounts of energy released from such a reaction.  Many of the developments causing and caused by nuclear technology was centered around fear. World War II was a desperate time when both the Allies and the Axis forces were trying newer and more creative ways to gain advantages on the battlefield. In an effort to create a bigger explosion and gain an advantage in the war, the United States of America began Project 

Manhattan.
The result of Project Manhattan was the conception of nuclear bombs. Fat Man and Little Boy are the names of the two bombs that would forever be etched in mankind’s history. Little Boy was dropped on Hiroshima and Fat Man on Nagasaki. The effects were devastating. By December 1945, the estimated dead in Hiroshima was 135,000 and in Nagasaki the estimate was 64,000 dead according to the Manhattan Engineer District (1946).

To put things in context, a comparison between the nuclear bombs and another powerful bomb made in the United Kingdom will be made. The United Kingdom had also developed a powerful bomb called the “Grand Slam”/ Tallboy bomb which was capable of driving itself into the ground, detonating to cause a camouflet, or a cavern underground, shifting the ground to undermine the opposition. Germany had been the victim of many such Tallboy bomb attacks but continued resisting the Allies until its eventual demise in 1945 (UK Bomber Command – Campaign Diary, 1945). As for the Japanese, after facing the horrors of the two atomic bombs, lost the will to continue fighting as they would face a “rain of ruin” as warned by President Henry Truman (New York Times, 2010).

The development of new weapons is nothing new in the context of war. The typical reaction of other warring factions that fall victim of these new technologies is to adapt or find new technologies to compete with their enemies. However, few have been so great as to force entire nations into submission as is seen in the aftermath of World War II. The Japanese are shown to be fiercely loyal to their emperor and are even willing to sacrifice themselves literally through Kamikaze Plane crashes. Seeing such a proud nation bow down to the devastation of such a weapon is truly a turning point when it comes to warfare technology.

Politics: The Cold War

“I begin to believe in only one civilizing influence, —the discovery one of these days of a destructive agent so terrible that War shall mean annihilation and men's fears will force them to keep the peace" 

-Wilkie Collins, 1870

From a political perspective, the sheer potential carnage that could be caused by the bomb would be enough to make anyone afraid of it being used on them. This much could be seen in the likes of the Cold War.

The Cold War saw the world being split into Eastern and Western blocs, one bloc being aligned to the Communist Soviet bloc and the other to the United States of America. The role that nuclear weapons effectively played in this war was as the catalyst in an international game of chicken. This fear was eventually known as the doctrine of Mutually Assured Destruction (MAD) as both sides armed with nuclear weapons would effectively eradicate the other should the need to retaliate ever arise. The Doctrine of MAD was based on the belief that if both sides could destroy each other, it would function as a deterrent from starting a war in the first place. (NuclearFiles.org, n.d)
As if nuclear bombs dropped from planes weren’t bad enough, the development of the Intercontinental Ballistic Missile had the warhead deliver itself to you. Multi-stage rockets would carry the warhead between continents making an already deadly threat deadlier (Atom Central, n.d).

Tensions were highest when it came to the Cuban Missile Crisis in 1962. Russia was intending to place missiles in Cuba and in exchange gave Cuba economic and military aid. The US laid a naval blockade to stop the delivery of the missiles in response.  The confrontation between the America and the USSR saw the two blocs just a hair’s breadth away from sparking a nuclear conflict. Instead of opening fire, both sides came to an agreement: the US will not invade Cuba and the USSR will remove said missiles. Subsequently, the US removed its missiles from Turkey as well. (May E.R., 2011) We can see here that nuclear weapons played a crucial role in the war. First, its existence was the basis for preparation for retaliation and eventually that same fear would be the factor that prevented the conflict from brewing any further.

Today’s Concerns for Nuclear Weapons:
Nuclear weapons represent power. The power to cause massive harm and damage at the push of a button guarantees a fear and respect that can be used for international power-play. The nukes will be used to threaten and pressure other countries to their will. Another point to consider from all of this is that if any country tries hard enough, they too can be nuclear armed.  These days, as shown in the reaction to North Korea’s recent nuclear tests, the world is trying all it can not have any more nuclear armed countries. Unless the world sees no more need for nuclear bombs will there be an end to their manufacturing.

This same behavior also could be the spark of potentially bloody conflicts. Reactions to the recent North Korean Nuclear tests, were one of expectant retaliation, with South Korea and America performing military exercises close to North Korea following the tests. The world has seen enough war and especially with the current state of the global economy, cannot afford another one.

Possible Future Consideration for Nuclear Weapons:
While we are seeing a gradual reduction in the number of nuclear weaponry around the world, nuclear weapons are likely to be maintained by the countries who own them. Nuclear weapons’ symbolism of power and its proven ability to deter nuclear attack make it a viable option for most nations.  

Signs Pointing Toward it:
Hans M. Kristensen (2011) stated on the Federation of American Scientists Strategic Security Blog that the American government had plans to modernize its nuclear arsenal. This includes a $6.3 billion dollars’ worth of expenditure on the warheads in the stockpile through to fiscal year 2016 (Kristensen, 2011).


Nuclear Reactors Today
Introduction:
Nuclear sabre-rattling will continue so long as there is a country that believes that owning and testing nuclear weapons is a valid method of getting attention. However, the power of nuclear fission can be used for more than just genocidal purposes. Nuclear reactors can harness the energy from the nuclear fission reaction to generate large amounts of power for comparatively long periods of time. Despite the all these facts, nuclear power has gained infamy over the years due to accidents such as Chernobyl and The Three Mile Island incident. The most recent accident at Fukushima is a reminder that nuclear power still has effects on the world. These effects will be discussed in this section of the paper.
These days, 13.5% of the world’s energy is provided by nuclear energy from more than 430 nuclear power reactors across 31 countries (World Nuclear Association, 2012).  Nuclear energy is touted as a clean and efficient source of energy as it does not release greenhouse gases during the production of power as no fossil fuels are burned and uses less land space in comparison to other energy production methods such as wind farms and solar paneling. However, seeing the long term health effects of nuclear bombs, the nuclear waste produced from the power production process would have to be disposed of effectively or else, this method may not be as “clean” as is advocated.


Social impacts:
Nuclear power has been seen as boon to some countries. During the oil price shock of 1973, many countries were left reeling from the sudden price hike. Many of these countries were reliant on the fossil fuels to power their countries and some of them did not have much in the way of local fossil fuel re. To curb their reliance on a commodity that was subject to volatile prices, countries such as France and Japan turned to nuclear power.  Prior to Fukushima, Japan sourced 30% of its power from nuclear reactors and was planning to raise this to 40%.  France generates 75% of its power from nuclear plants thanks to government policy that focused on energy security after the oil price shock of 1974. (World Nuclear Association, 2013)

Some negative social effects of nuclear power are attached to concerns over health and safety. Anti-nuclear movements cite risks of nuclear accidents, especially the current case of the Fukushima Daiichi Power Plant incident, and nuclear waste disposal as some of their reasons for disliking nuclear power.  The Three Mile Island, Chernobyl and Fukushima disasters all saw thousands of people being evacuated from their homes due to the high levels of radiation found in the areas surrounding the power plants.

The relocation of the people from their homes is one of the greater negative social impacts brought about by nuclear power. In Chernobyl, more than 330,000 people had to be relocated after the disaster. Some of the people who left their homes behind felt a sense of injustice and also felt that out-of-place in society.  The ones who choose to stay behind ended up faring better psychologically. The migration of the people also caused a distorted demographics curve, having more elderly people and fewer professionals. This raises the death rates of the area while hampering economic recovery.

After the accident at the Fukushima Daiichi Power Plant in 2011, which saw 160,000 people evacuating the surrounding area, Japan has seen a rise in anti-nuclear demonstrations. Mari Saito and Sophie Knight (2013) recently reported from Reuters that more than 15,000 people attended a protest urging the government of Japan to reject nuclear power. A recent poll stated that 70% of Japanese intended on eventually phasing out nuclear energy.

From the information gathered, it can be said the social impact of nuclear energy is reliant on the circumstances of the time. People welcomed it for the benefits it brought and rejected it when the detriments were brought to light. Public perception is a fickle thing. Now that the world is facing a grim reminder that nuclear technology is not 100% fool-proof, we can expect there to less public support for nuclear energy in times to come.

Environmental Effects:
Nuclear power has been touted as a clean energy as it does not contribute to carbon dioxide emissions during the generation of power (US Environmental Protection Agency 2013). Especially during a time when the world is aware of the need to reduce greenhouse gas emissions into, the has been taken into  account by powerful countries such as China. According to LiveMint (2013), China plans on building 200 more nuclear power plants, reaching a pace of 10 new plants a year. This is to counter the high amounts of pollutants generated by its coal-fire power in its industries.

Nuclear power plants require a lot of water in the production of its electricity. The water is used to both create steam to move the turbines and to act as a coolant to the systems. Apart from the power plant’s use of water, waste water contaminated with heavy metals and salts are the by-product of many types of power plants, including nuclear ones.

Radioactive water from cooling purposes when it comes to containing nuclear power plant accidents are also an environmental hazard. The water pumped into the Fukushima facility to cool down the facility becomes irradiated. Aljazeera (2013) reported that leaks from the power plant have caused the radioactive water to seep into the ground and some of it may even have reached the Pacific Ocean. Nicholas Fisher, a marine biologist at Stony Brook University in Stony Brook, N.Y., told LiveScience that for seafood caught 160 km away from the site would be safe but the same cannot be said for the seafood caught closer than that; this pollution is affecting Japan’s marine life. (Lewis, 2013)  All these developments would lead to the increase of radioactivity of the site, delaying cleanup efforts.

Nuclear power plant accidents such as the Chernobyl disaster release large quantities of radioactive material into the air. This fallout travels and affects areas downwind, spreading its radioactive substances to the neighboring areas. From Chernobyl, “(a)bout 4300 km2 are in the no-go zone. Another area of about 7000 km2is considerably contaminated by 137Cs. In Belarus, Ukraine and Russia, a further 130.000 km2 were less severely contaminated. Similar levels also occurred in 60.000 km2 in other parts of Europe.” (Euronuclear, 2006)

Nuclear power plants must change their fuel every 18-24 months. The spent fuel released from these processes form radioactive waste that must be disposed of. Concerns arise as this radioactive waste is dangerous to living beings as it may cause cancer. At the moment, most of the spent fuel is kept on site at the nuclear power plants.  Seeing how these are dangerous, many people adopt the NIMBY (Not In My BackYard) style of thinking.  For instance, in November 2010, an anti-nuclear group “Wiedersetzen” attempted to block a shipment of nuclear waste from France to Germany that was to be placed in a salt deposit in Gorleben. (Public Intelligence, 2010)

Nuclear power is a double-edged sword when it comes to environmental impact. On one hand, it is seen as one of the “cleaner” sources of energy as it releases no carbon dioxide into the atmosphere during energy production. On the other hand, its nuclear waste and waste water pose serious problems to the environment. Unless we are able to develop a fool-proof way of safely disposing of the waste could nuclear power truly be called a clean source of power.

International political effects:
The effects of nuclear power on international politics is once again about fear. One prominent example of this is Iran’s uranium enrichment program. Iran’s nuclear program attracted a lot of international attention during its height in 2002. A clandestine operation by an opposition group exposed that Iran also had uranium enrichment in progress. Uranium used for civilian purposes may be enriched further to supply weapons grade uranium for warheads. Iran’s government has been defending the program and claiming that the program is being used for peaceful purposes. The world however, is not so convinced of Iran’s government’s honesty.  (BBC, 2013)

Iran had hidden the uranium enrichment program for 18 years. The UN stepped in and demanded that unless Iran can convince the Security Council that the enriched uranium would only be used for peaceful purposes, it should shut down its uranium enrichment operations. A report by the International Atomic Energy Association claimed that Iran has been performing acts indicative of building nuclear weaponry including “The acquisition of nuclear weapons development information and documentation from a clandestine nuclear supply network “ and “Work on the development of an indigenous design of a nuclear weapon including the testing of components” .(IAEA, 2011) Iran still continues to enrich uranium under the justification that it is within its rights provided by the NPT (Treaty on the Non-Proliferation of Nuclear Weapons) to do so.  (BBC, 2013)

In this case, Iran may or may not have enriched uranium for the purpose of creating nuclear warheads, but that is not the point. The point here is that the UN is afraid that Iran could be making a bomb and is taking steps, such as economy-crippling sanctions, to stop Iran from carrying out its uranium enrichment program. Once again, we are seeing two sides that refuse to back down, which may bring us to conclude that there is a vicious cycle. Did the UN consider that perhaps their sanctions in retaliation to Iran carrying out their enrichment program is the same thing that is driving Iran to continue it?

Future Considerations for Nuclear Energy:
Nuclear power’s infamy arises from the harmful effects of its radiation. To summarize, Fukushima’s radioactive water leaks pollute the ocean and the area around it, Chernobyl and Fukushima’s disasters caused the people to be evicted from their homes which then caused numerous social effects. These effects have caused some countries such as Spain, Germany, Italy and Japan itself to reconsider nuclear energy (Wikipedia, n.d).

This may not spell the end for nuclear energy as countries such as China and India have considered nuclear energy as a viable alternative source of energy. China’s reason for doing so is to begin reducing its carbon emissions from its coal power dependency (Reuters, 2013). Just like nuclear weapons, as long as people see good reason to apply such technology, that technology will continue seeing use, regardless of public perception.

Conclusion:
Nuclear weapons and nuclear energy will continue being a part of our lives. This strain of technology has seen many momentous moments in history originally in war and later in accidents occurring close to home. Nuclear energy gives people many reasons to fear and despise it, yet may even be one of the better solutions offered in today’s challenges such as global warming. Perhaps nuclear technology will continue to be part of the technology’s family, the black sheep of the family.

Week 7: BioBusiness Revolution: Agribiology, Environmental Life Sciences and Industrial Biotechnology (Past, Present and Future)

Brief Overview:
This week, we’re looking at the other half of biobusiness, namely the businesses focusing on green biotech (plants), white biotech (industrial) and blue biotech (blue).  The technology adoption gap that exists in biotechnology is 8 years long; it takes 8 years for a great innovation to be adopted by the masses, which explains why biotech seems to be lagging behind most other industries.

Agriculture amounts for 40% of the world’s jobs but only produces 25% of the world’s GDP. This imbalance might change in the future as more people shift to the cities in the hopes of finding new jobs and better facilities. However, this same change could amount to new problems. These facilities provide for a sedentary lifestyle as consumption patterns, exercise, healthcare and energy usage all change. These new problems could be great opportunities to enterprising people though.

Now to briefly recap on the latest developments of biobusiness. First, we’ll look at the agricultural and food sector. Fish farming accounts for 70% of the world’s fish supply, GM foods (such as vegetables and grain and even fish) are still a highly debatable topic, pre-cut vegetables are made for our convenience but may not be the best development for the environment. Sustainability of the world’s natural resources such as forests also rest on our judicious or reckless placement of farms and infrastructure.

Next, we’ll take a look at industrial biotechnology. One of the best developments in this industry so far is the use of enzymes. These enzymes are used in detergents, cleaners, tanneries, tenderize meat, create medicine and even have uses in the field of mining. Thanks to their properties of being bio-catalysts, there are many advantages to using these (even more so than last time). There is also a change of some farmers to specialized farmers (farmists). These farmers can apply mechanization in large farming to  save costs of production and manpower. Also, these have applications in the production of certain products such as synthetic spider’s silk protein which will be discussed in the key takeaways.

Key takeaways:
GMO’s are a double-edged sword. As with any new development that we come up with, there is a chance that it will deliver great amounts of good as much as it can deliver a whole load of negativity. GMO foods involves swapping or adding genes to manipulate the traits of the organism in question. Higher yields may be gained by inserting such a gene into rice and corn for instance, but what if these genes also create new allergens? There are also some studies conducted that show that animals fed with GM foods for a few generations suffered from enlarged kidneys and livers and some of the animals tested over a few generations (of the animals) showed that they produced fewer offspring compared to their non-GMO fed counterparts. It is fair to say that some of these tests may not have been done correctly but the there is a silent implication it might be true if the GMO companies’ employees themselves refuse to eat the GMO products (click here).

On the other hand, we can also say that without genetic modification of the plants, we wouldn’t even have agriculture. The process of domesticating plants for agriculture has been going on for thousands of years. These processes are also part of the Green Revolution allowing more food to be grown with less land, increasing overall output and providing more food to the masses. Another point worth noting here is that our ancestors performed genetic modification without the use of high-tech gene placement methods, the plants themselves could do this naturally so to speak. If our current methods of gene manipulation for GMO food is wrong, hopefully we will be able to find out before it’s too late.

Enzymes are awesome. The industry has managed to apply enzymes in a variety of uses as discussed above. Enzymes were used mostly for the production of some confectionaries and drinks like cheese, yoghurt and beer. Nowadays, these little guys help to reduce water requirement for some products, remove the need for vast amounts of harsh chemicals being applied to fabrics in fabric production and are even able to help in the mining sector! These are also helping to turn more of our industries into environmentally friendly ones making us one step closer to leaving no negative effect on Mother Nature. This proves that it may be possible for mankind to live in harmony with nature without disturbing the delicate balance.
