More tragically, they must endure the silence of human hearts” (Williams, 2008). Humans have created so many problems on this planet, problems that they ignore and leave to worsen. One such problem is that of the extinction crisis. While humans may attempt to save some endangered species from extinction (pandas, cranes, etc.), they ignore other endangered species (amphibians, reptiles, etc.). Although these ignored species are small, they are vital to some ecosystems. One ecosystem that amphibians play a vital role in is the tropical rainforest. A tropical rainforest contains more diverse plants and animals that other ecosystems. They are warm and very moist, which leads to tall trees and dense foliage. Amphibians are important to this ecosystem because they provide a food source to certain birds (ravens, etc.) and mammals (lemurs, etc.).
