Should there be government regulations to protect the environment from genetically engineered crops?

The environment has become a huge issue today, and its protection an even larger one. No matter what your point of view on GM foods, we should examine the effects that the GM food crops have on our environment.GM crops are being breed to contain their own pesticides, this raises many concerns. Could insect become immune to these "naturally" produced pesticides, causing us to manipulate the already distorted DNA of the crops? And even if we did breed the crop to create a pesticide against insects, how many more times must we do it in order to assure the crops integrity? Besides the insects, we must also turn to the soil. What harm are we doing to the soil when we plant such crops? The answer is that these GM crops are created to withstand harsh growing conditions, no matter what the state of the soil. This could cause a depletion of vital nutrients, making, once fertile lands, utterly useless.
