Question

1. what is a possible negative effect of deforestation (cutting down forests)?

Explanation:

Deforestation removes trees which are crucial for absorbing carbon dioxide and releasing oxygen. Without them, the amount of carbon dioxide in the atmosphere can increase, contributing to global warming. Also, trees hold soil in place; when they are cut, soil erosion can occur as there's less root structure to stabilize the soil, leading to problems like reduced soil fertility and sedimentation in water bodies. Another effect is the loss of habitat for many plant and animal species, which can lead to a decrease in biodiversity as these species may struggle to survive or go extinct.

Answer:

One possible negative effect of deforestation is increased soil erosion (since tree roots help hold soil, and without trees, soil is more easily washed or blown away), or loss of biodiversity (as many species lose their habitats), or an increase in greenhouse gases in the atmosphere (as trees absorb carbon dioxide, and fewer trees mean more carbon dioxide remains in the air, contributing to global warming).
