Biodiversity refers to the complex relationship between plants, animals, humans, and the environment. If variety in one part is reduced, the other parts are also affected.
Sites listed here will focus on conserving the whole range of animals and plants, as well as preserving different habitats.
Sites about conserving a single species of animal should be sent to Endangered Species
Deforestation is the removal of forested areas, so that they no longer are forests.
Desertification is the process of land turning into deserts, caused from various factors including climatic variations and human activities.
