Once an area loses biodiversity there are increased risks of damaging the surrounding environment and of a shortage. Insects that once feasted on different kinds of crops leave the area, the animals that eat those insects leave the area, and pests can move in that have built up a resistance to the genetic toxin. If the genetically engineered crops fall victim to some new disease or pest, then the entire crop may be lost as opposed to only one kind.
Scholars who have done a study on this could explain it better. See below under Related links.

What are some benefits of genetically engineered crops?
It depends on how they are genetically engineered. The possibilities are almost endless (given time to research the idea) but there are 2 genetic modifications that seem to be most common. Making a crop easier to grow in harsher climates, or causing the crop to grow faster. There are also drawbacks, such as many genetically engineered crops having lower nutritional value, but scientists are constantly working on overcomming these problems, and most of the genetically engineered crops used today are free of these problems.
What is a current benefit gained from genetically engineered crops?
One current benefit gained from genetically engineered crops is increased yield and productivity. By incorporating traits that make crops more resilient to pests, diseases, and environmental stresses, farmers can produce more food on less land. This can help improve food security and reduce the environmental impact of agriculture.
Why do Some farmers currently grow genetically engineered crops an argument against the use of this technology is that?
Some farmers choose to grow genetically engineered crops because they can offer benefits like increased yield, pest resistance, and tolerance to herbicides. However, some argue against this technology due to concerns about potential environmental impacts, the development of herbicide-resistant weeds and pests, as well as the long-term effects on human health and biodiversity.

What would likely possible negative impact of the use of genetically-engineered crops?
The use of genetically-engineered crops can lead to potential negative impacts such as reduced biodiversity, as engineered plants may outcompete native species. Additionally, there are concerns about the development of pesticide-resistant pests, which could result from the widespread use of these crops. Furthermore, reliance on a few genetically modified varieties may increase vulnerability to crop failures due to disease or climate change. Lastly, there is ongoing debate about the long-term health effects on humans and the environment, which remain uncertain.
Is an example of biotechnology?
Genetically engineered crops, like corn and soybeans, are examples of biotechnology.
What is one of the problems with improving the food supply by genetically engineering better crops?
Some crops are genetically engineered to resist certain herbicides, which means the herbicides they are engineered to be resistant to can withstand having the herbicide sprayed directly on the crop. A known problem with these crops is that after a number of years, more herbicide is needed to control weeds. Because of this, more herbicides are sprayed on the crops and end up in foods. The safe limit for glyphosate (Round-up) in foods has been raised by the EPA in the United States and the use of Glyposate on crops has doubled in the years since Glyphosate resistant crops have been commercially grown. Other crops are genetically engineered to produce an insecticide in the plant itself. Though the insecticide is suppose to target certain insects, two concerns are that non-targeted insects are being killed and people's and animal's health may be affected when those crops are eaten. Generally, some believe horizontal transfer of the engineered genes in the crops may occur. Another problem that has occurred is weeds have developed resistance to the herbicides crops have been engineered to resist. The absence of long-term studies concerns others, making some feel that they are the long-term study.
How might these genetically-engineered crops impact the environment?
They will help the environment by allowing farmers to use fewer pesticides.
What characteristic is often genetically engineered in crop plants?
By far the characteristic that is most often genetically engineered into crop plants is resistance to herbicides, with engineering crops to produce a substance that kills insects into the plant itself a close second.
What are the current benefits of having foods made from genetically modified crops?
Some benefits of genetically modified crops include increased crop yields, reduced need for pesticides, and improved nutritional content. Additionally, GM crops can be engineered to be more resistant to diseases and harsh environmental conditions, helping ensure food security for a growing global population.
How are GM food crops produced?
GM crops are produced much like other crops, except that many that are grown have been genetically engineered to be resistant to herbicides or to produce an insecticide in the plant itself.
Why are some GMO crops classified by the EPA as pesticides?
Some GMO crops are genetically engineered to produce a substance that kills insects when they is eaten by them. It is for that reason that some GMO crops are classified as pesticides by the EPA.
