What are some potential impacts that might result from introducing genetically engineered organisms into the soil habitat?

Answer 1

The biggest potential impact would be contamination of equivalent non-genetically engineered organisms. For gmo plant parts and seeds spread by wildlife and wind.

Yes the main impact would be if the genetically modified organisms spread and managed to breed or fertilise other plants or animals. However in the media this is always portrayed as negative but in real life that is not the case. Nothing has only negative consequences. What people tend to forget is GM organisms are nothing new - dogs being bred for their speed or colour for example is a form of genetic modification, as is growing roses to achieve a particular type or colour of bloom. Only difference is that with modern techniques it can be done in a lab in a few months rather than taking years or decades by going through several generations. I personally see nothing wrong with modifying something like wheat or corn to grow bigger and better and more resistant to pests - our ancestors would have jumped at the chance. The modifications themselves are subtle and could easily be achieved by the breeding process - selecting normal wheat or corn plants with the best characteristics and growing a new batch from them, then selecting the best plants from that batch and growing a new lot from them and so on. It just takes a lot longer and is easier to do in a lab. What you find is the people who oppose it do not know anything about the subject and are generally very stubborn, close-minded and resistant to change of any sort.
