Capybara

The capybara is smaller because of deforestation. When people cut down the trees less fruits that grow on that tree will likely stop producing as fast. Also because of greenhouse gasses water might dry out and stop the aquatic plants that they eat. With it also being so hot a capybara's fur will likely becomes even more spread out to keep them cool. Capybaras feet will also be more webbed because their semi-webbed feet help them go through thick swampy water, with the lakes might become even more swampy/think. Capybaras will most likley need even more webbed feet.
