Question

first, how does deforestation contribute to climate change?
a) nitrous oxide is a greenhouse gas, which trees remove from the atmosphere
b) trees store carbon, removing them results in more co₂ in the atmosphere
c) methane is a greenhouse gas, which trees remove from the atmosphere
d) trees store oxygen, removing them results in more oxygen in the atmosphere

Explanation:

Trees are carbon - sinks. Through photosynthesis, they absorb carbon dioxide from the atmosphere and store carbon. Deforestation reduces the number of trees, so less carbon is stored and more carbon dioxide is released into the atmosphere, contributing to the greenhouse effect and climate change. Nitrous oxide and methane are not primarily removed by trees. Also, trees release oxygen during photosynthesis, not store it in a way that affects atmospheric oxygen levels in the context of deforestation and climate change as described in option d.

Answer:

B. Trees store carbon, removing them results in more CO₂ in the atmosphere
