This session we discussed about bio-business in the agriculture (agribiology), environmental life sciences and industrial life sciences.
Biotech in Agriculture and Food Processing
Man has long been engineering or modifying the food we consume. From selective breeding to get better crops or meat to the more recent genetic modification (GM) to get crops that are resistance to diseases, higher yields and use less resources.
There are many who are resistant to GM food. However there are many food products that we consume daily that are GM. Examples are tomato ketchup and culture milks such as Yakult. Scientists are just doing it in a more accurate manner. GM is the next green revolution that will feed our growing world population, the same way machines and pesticides have increased yields in the previous green revolution to feed everyone. With limited arable land, we have to find a solution that can dramatically increase yields.
GM can promise to deliver crops that can produce more in a single harvest and can produce crops that will have shorter harvest cycles.
The use of pesticides have caused many environmental problems such as causing imbalance to the ecosystem, contaminating water sources and causing algae blooms and dead zones in lakes and seas. GM crops will drastically reduce and probably eliminate the need pesticides as corps can be modified to be resistance to diseases and pests.
Next, governments should encourage farmers to consolidate their farms and pool together to have a bigger farm so that it would be economical for the poor farmers to get machines and use GM seeds. Developed countries have very high yields with a very small agriculture workforce. In developing nations, it is common to see big families farming on a small plot of land and being dependent on the harvest from that small land. This means that a large portion of the harvest goes to feeding and sustaining the family with little or no excess to improve their farm. Government has to encourage more people to move to more urban towns. While this may lead to overcrowding and slums and diseases in cities, after a painful transition and proper government policies to educate, manage housing and more, most people will see increased incomes.
There definitely cases where certain GM seeds may not grow in certain areas or might wipe out the local species affect other farmers who are did not buy those GM seeds. International institutions are now set up to regulate and look in to such concerns. This will help ensure that such problems can resolved.
Just because there are problems, that does not mean that solution is wrong. We should recognise the opportunities and work to find ways to make things work. We have to recognise that feeding 10 billion people cannot be solved by our current methods especially we when we have dwindling arable land.
Biopharming is an interesting area where drugs can be given to patients especially chronic patients of diseases such as diabetes. This can help increase absorption of drugs and reduce rejection.
Environmental Life Sciences
Biodiesel, bioenergy through waste materials and algae cleaning the environment and providing biofuel are some interesting biotech.
Algae that feed on waste like sewage and grow at very rapid rate is starting to show promise to be a major solution. This is a renewable source of energy and the algae helps to treat wastes as well. This technology can be easily applied in developing nations, allowing them to have cheaper and more diversified energy sources. Developing nations can even use grow excess and sell to other nations. With the integration of the smart grid, developing nations can move up the value chain and sell energy to nations who need it. This biofuel eliminates the problem of replacing food crops that biofuel such as corn, sugarcane and palm poses.

Overall I give this lesson an 8 out of 10. I have learnt quite a few new things and the presentations were good.
