Detailed explanation-1: -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. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive.
Detailed explanation-2: -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.
Detailed explanation-3: -Protecting biodiversity can help us adapt to climate change. Healthy ecosystems will be more resilient to climate change and so more able to maintain the supply of ecosystem services on which our prosperity and wellbeing depend.
Detailed explanation-4: -Biodiversity maintains the ecological balance. It helps in the healthy existence of humans and other species in the ecosystem. It helps in high productivity and human wellness. Biodiversity provides humans with valuable genetic diversity.
Detailed explanation-5: -Biodiversity is the number and variety of plants, animals and other organisms that are living in an ecosystem. Biodiversity is a measure of the variety of organisms that exist in different ecosystems. Bio means ‘life’, diversity means ‘variety’. The species is the fundamental unit by which we can measure biodiversity.
