I just finished reading this article originally from "Futurist." It discusses the potential that genetic engineering has but also the precautions that we must take to ensure its safety and reliability. The passage began by listing some positives and negatives of biotechnology. One issue, toxic-waste cleanup, could largely benefit our society ecologically and economically. Genetically modified (GM) bacteria could eat up toxic materials which would be less expensive than conventional cleanup methods. But, unforeseen problems could arise, and you have to be very careful when cleaning up hazardous waste.
Scientists can GM plants so that they produce their own insect-killing toxins. Although insect pesticides are used to protect plants, they are dangerous to the environment and also expensive. Butterflies have died when scientists have tested the GM plants because they try to eat it. If they survive, though, they could potentially produce their breed of insects that are difficult to kill. It's hard to tell where you draw the line. I think that it should vary per situation. I do not think that any GM bacteria, plant, crop, etc. should be produced unless extensive tests have proved that they have no negative effects on the environment (including long-term effects). What is not visible at first sight may have a drastic effect later on. Also, as a citizen, do we have a right to know what is genetically engineered? For example, if you are at a grocery store, should a tomato be required to have a "GM" sticker on it? It think so. People have the right to decide what kinds of food they eat. To many, this decision is influenced by where the food comes from and if it is naturally grown.
