Biodiversity maintains the health of an ecosystem. The decline of biodiversity leads to environmental changes and destruction, as well as invasions of non-native species. Biodiversity allows for an ecosystem to accommodate to disorders, such as species extinction, fires and floods.
Results of experimental studies revealed that species abundance increases the ecosystem's productivity. Biodiversity makes adequate conditions to preserve life on the Earth, providing oxygen and cleaning water and the air by absorbing chemicals.
Diseases are avoided by genetic diversity, helping species to adapt if changes occur in their environment. Research conducted on diverse species of plants and animals led to important discoveries of remedies that cure diseases and extend the life of human beings.
In conclusion, protecting biodiversity, by all means, is the most important thing that all we can do to protect life on the Earth.
