The correct option is B) Human development is changing the rainforest too quickly.

Explanation:

The development of humans have been imposing stressful situations in the natural wildlife since the beginning of human activities.

Rainforests, such as the Amazon rainforest, are cut down by humans to dangerous levels in order to meet their luxury needs such as paper and building houses, factories, industries etc. This massive deforestation can cause global warming and many of the wild-life organisms to become extinct. Also, destruction of the Amazon rainforest is leading to lesser amount of oxygen present on earth which is essential for breathing.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
