High biodiversity reduces the probability of extinction and supports natural evolution. The genetic and symbiotic relationships between species contribute to the natural order, survival, linking food chains, natural cycles, and recycling.

And also, biodiversity is essential for ecosystem resilience, natural evolution, and the provision of ecosystem services that benefit both nature and humans. Low biodiversity, on the other hand, can lead to ecosystem instability, reduced services, and potential conflicts over resources.

Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.Biodiversity forms the web of life that we depend on for so many things – food, water, medicine, a stable climate, economic growth, among others. Over half of global GDP is dependent on nature. More than 1 billion people rely on forests for their livelihoods. Biodiversity is extremely important to maintain the ecological system. Most Noteworthy many species of plants and animals are dependent on each other. Therefore if one of them gets extinct, the others will start getting endangered too. Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. The amount of diversity at the genetic level is important because it represents the raw material for evolution and adaptation. More genetic diversity in a species or population means a greater ability for some of the individuals in it to adapt to changes in the environment. Support local and regional projects aimed at tackling biodiversity loss. Buying fewer products and making sure the products you do buy minimise the impact on biodiversity. Investing in ways that promote biodiversity and reducing waste of consumer goods: food, clothes, electrical appliances, etc. Ecosystems with high biodiversity can recover from disturbances better than ecosystems with low biodiversity. This means healthy ecosystems are more likely to continue to support humans even as the earth goes through extreme changes.Declining biodiversity lowers an ecosystem's productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem's services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.). The biodiversity of species, or species richness, is often used as a measure of ecological health. High biodiversity, with many species present, is good. It usually means that an ecosystem is healthy and relatively undisturbed by humans. Low biodiversity is characteristic of an unhealthy or degraded environment. Estuarine areas have high biodiversity compared to other areas. Trophical rainforests are rich in terms of biodiversity. Arid and semiarid areas have low biodiversity. Deserts, for example, contain limited numbers of specie. Ecological life support biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
