What was the long term environmental risk of replacing mixed natural forests with monoculture plantations?
Answer and explanation
Correct answer: Natural diversity and habitats could decline
A mixed natural forest contains many kinds of trees, plants, animals, insects, and microorganisms. Different species provide different foods, shelters, and ecological functions. A monoculture plantation grows mainly one tree species over a large area. Although it may supply timber efficiently, it does not provide the same variety of habitats and resources. Therefore, replacing a natural mixed forest can reduce biodiversity and weaken the balance of the ecosystem.
Option A is correct because it directly identifies the long-term environmental risk: natural diversity and habitats may decline. Options B, C, and D are unrelated or opposite to the likely result. A plantation does not make every species increase, end forest laws, or remove government control. The key idea is that uniform planting can make an ecosystem less diverse and less resilient to pests, disease, and environmental change.
