Give examples of how humans have increased their food supply and what effects these methods have on the environment overall.
In the United States, we are fortunate to have an abundant supply of food, and much of this is due to our agricultural technology. However, there are many concerns about our food source, including genetically modified crops, the use of more chemicals, and climate change just name a few. Give examples of how humans have increased their food supply and what effects these methods have on the environment overall.
There are many examples of genetically engineered organisms that have resulted in a more plentiful, productive food supply, particularly in American agriculture. When I taught this unit in my class, we viewed a video on the subject of genetic engineering in agriculture. One of the examples of improvement that stood out was a visit to Mexico, to a university that studied the cultivation and improvement of the corn plant, which is a staple food product for the people of Mexico. The original corn plant, from which our modern, full eared corn comes from, barely had kernels that fell out quite easily. The much more developed corn we have today is a result of years of selective breeding, which is one of the precursors to genetic engineering today.
Another example is the development of the "super-salmon", where this breed of salmon is able to continue gowing even in the cold season, when the growth hormone in regular salmon slacks off. The result is a fish that is 3 to 4 times the size in the same amount of time.
As with all new technology, only time will tell whether the use of this technology was a benefit or a curse. Studies will continue to monitor and record data on these examples and it will be left to future generations to judge it good or bad.
