Benefits of Engineered Plants

Researchers who are creating genetically engineered plants present data to show the benefit of using them. With the increasing world population and the ever decreasing availability of arable land, the benefits include:

1. Increasing yield of many crops and thereby reduce use of marginal agricultural lands.
2. Increasing the resistance of plants to various pests and herbicides.
3. Decreasing the use of herbicides and pesticides that decidedly have detrimental environmental effects.
4. Increasing saline and drought resistant plants that can be grown on soils that already have had the salt content increased because of irrigation or rainfall decreased because of global warming.
5. Provide the nutritional value of plants for human consumption.

There is always another side of an argument; there are disadvantages of using genetically engineered plants?
