What is biodiversity and is it important?
Biodiversity is essentially the number and variety of plants, animals and other organisms that exist on earth. The variety of all living things allows the survival of mankind by providing the resources for food, fuel, and shelter. There are approximately 70,000 species of plants, also known as flora, on earth. All species of animals are known as fauna, which includes birds, mammals, fish, reptiles, insects, crustaceans, and molluscs.
Whether looked at on a global scale or life within a certain area on earth, biodiversity is the study to be able to recognize and have more understanding of the relationships between species. Biodiversity helps to improve the productivity of the ecosystem where all species play a special role. The larger the number of plant species, the greater number of fauna it can support. When ecosystems are healthy, they are more able to survive disasters.
Biodiversity varies globally as well as within regions of the earth. The diversity of all living things depends on temperature, precipitation, altitude, type of soil, geography and what and how many other species are the present. Diversity is much higher in the tropics and rain forests and much less in deserts and the polar regions.
