Question

what effects do modern farming techniques have on world biodiversity?

check all that apply.

• the relationship between biodiversity and monoculture is mutually beneficial, so biodiversity increases with crop yield.
• biodiversity is expanding as more and more crops are grown.
• monoculture, pesticides, and chemical fertilizers have greatly reduced the biodiversity of the world.
• pesticides have helped to create new environments without insects, thus creating new habitats and increasing biodiversity.

Explanation:

Analyze the impact of modern farming on biodiversity

Modern agricultural practices such as monoculture (growing a single crop over a wide area), heavy pesticide use, and chemical fertilizers simplify ecosystems, eliminate native plant and insect species, and disrupt local food webs, leading to a significant reduction in global biodiversity.

Evaluate the given statements

• Statement 1 claims monoculture and biodiversity are mutually beneficial, which is false because monoculture reduces genetic and species diversity.
• Statement 2 claims biodiversity is expanding, which is false as modern intensive farming is a primary driver of biodiversity loss.
• Statement 3 correctly identifies that monoculture, pesticides, and chemical fertilizers have greatly reduced global biodiversity.
• Statement 4 claims pesticides increase biodiversity by creating insect-free environments, which is false because removing insects reduces biodiversity and disrupts ecosystems.

Answer:

• The relationship between biodiversity and monoculture is mutually beneficial, so biodiversity increases with crop yield.
• Biodiversity is expanding as more and more crops are grown.
• Monoculture, pesticides, and chemical fertilizers have greatly reduced the biodiversity of the world. (Correct answer)
• Pesticides have helped to create new environments without insects, thus creating new habitats and increasing biodiversity.
