Things that are not an effect from the genetically modified organisms are:
- Farmers must buy new seeds each year;
Be it a natural seed or a genetically modified seed, the farmers have to buy new seeds each year. The fact that there's genetically modified seeds in use doesn't change anything in the supply of seeds department, as the process is totally the same.
- Pesticides and herbicides are used more frequently;
The increasing of the usage of pesticides and herbicides has began with the development of the same, much earlier than the genetically modified organisms reached the market and farms. Since they have been used heavily for quite some time now, and their usage has been steadily increasing, we can not say that the relatively new genetically modified organisms had any effect on that.
