Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. ... Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations.

Why is biodiversity necessary and why it should be conserved?

Biodiversity conservation protects plant, animal, microbial and genetic resources for food production, agriculture, and ecosystem functions such as fertilizing the soil, recycling nutrients, regulating pests and disease, controlling erosion, and pollinating crops and trees.

Why should we conserve biodiversity short answer?

Plants and animals depend on each other in order to survive, therefore the destruction of one would affect the life of the other. Hence, we should conserve biodiversity to prevent these species to become extinct and to maintain a balance in the nature.
