What effects do modern farming techniques hove on world biodiversity? click all that apply
A) Monoculture, pesticides, and chemical fertilizer have greatly reduced the biodiversity of the world
B) Pesticides have helped create new environments without insects, thus creating new habitats and increasing biodiversity
C) Biodiversity is expanding as more and more crops grown
D) The relationship between biodiversity and monoculture is manually beneficial, so biodiversity increases with crop yield

Answer 1

Explanation:

A) Monoculture (single crops), pesticides, and chemical fertilizers have greatly reduced the biodiversity of the world

is correct option.

Answer 2

A) Monoculture, pesticides, and chemical fertilizers have greatly reduced the biodiversity of the world.

• The use of modern farming techniques substantially reduced the biodiversity of the world as this method of farming involves the use of chemical fertilizers, pesticides, and herbicides.
• The use of such chemical fertilizers results in soil degradation and leads to soil pollution.
• The use of pesticides and insecticides, not only kills undesirable insects but also may have chances of killing crop-friendly insects. This might result in an imbalance of biodiversity.
• The use of monoculture reduces the fertility in the soil as the same type of crop is sown in the entire crop area and even after every harvest, the sowing of the same crop might result in nutrient-deficit crops.
