1. The conversion of rain forest to cattle ranches has most likely affected lakes and rivers in the Amazon River basin by increasing sediment runoff and pollution into the waterways. Deforestation can lead to soil erosion, which in turn can result in sediment being washed into nearby streams and rivers. Additionally, runoff from ranches, such as fertilizers, pesticides, and animal waste, can also contaminate the water, impacting the aquatic ecosystem and water quality.
2. The loss of rain forest in the Amazon River basin has most likely affected levels of carbon dioxide in the atmosphere and the process of global climate change by reducing the forest's ability to act as a carbon sink. Forests absorb carbon dioxide during photosynthesis and store it in trees and soil. When trees are cut down and burned or left to decay, the stored carbon is released back into the atmosphere as carbon dioxide, contributing to the greenhouse effect and global warming. Deforestation in the Amazon rain forest therefore significantly contributes to the increase in carbon dioxide levels in the atmosphere and exacerbates climate change.
Deforestation in the Amazon River basin converts rain forest to open areas that are often used for cattle ranching During the last 50 years, over 15 percent of the Amazon rain forest has been lost.
