Genetic biodiversity is the differences of DNA among animals and plants. Ecosystem biodiversity is the existence of a variety of environments, such as deserts, mountains, forests, lakes, wetlands, agricultural landscapes and rivers. Species biodiversity is found within biodiversity hot spots that support the world's mammal, amphibian, bird, reptile and plant species.

The benefits of biodiversity are associated with its economic values and role in sustainable development, such as keeping the environment in a state of natural balance. The revenue generated from fisheries, forestry and farming demonstrates the economic importance of biodiversity. According to Global Issues, goods provided by biodiversity include fuel, building material and water. Biodiversity also provides services such as shelter, waste decomposition, moderation of temperatures and floods, nutrient cycling, pollination of crops, control of diseases and pests, purification of air and maintenance of genetic varieties. Additionally, biodiversity provides aesthetic and cultural benefits to society. Climate change threatens biodiversity by causing an imbalance in the environment.
