I gave my students this multiple choice question: Many different plant and animal species live in the Amazon rainforest. Which is the most likely result of large areas of deforestation in the Amazon rainforest?

Only one answer is correct among these 4 choices:
- an increase in animal populations
- a decrease in oxygen production
- an increase in precipitation
- a decrease in pollutants

Could you tell me which one is correct?

a decrease in oxygen production
