The observance of International Biodiversity Day (May 22) was yet another reminder of the pivotal role our natural world plays in resolving the climate change crisis, which, along with the decline of biodiversity, poses an existential threat to our future. Biodiversity, the rich variety of life forms and their interconnections with each other and the environment, is everywhere: inside our bodies as ubiquitous microbiomes, in our backyards, villages, towns, and cities, and in remote wild places as well-organised ecological communities and ecosystems. Maintaining and enhancing biodiversity on land and in oceans is perhaps the least expensive mechanism to sequester carbon dioxide from the atmosphere so as to cool our land and oceans.
Mitigation of climate change is but one of the several benefits we derive from biodiversity. It also fulfils our basic needs for food, shelter, medicines, mental health, recreation, and spiritual enrichment. To face the continuing decline in the quality of our environment, we will need to rely more and more on solutions that draw upon biodiversity or nature, also called nature-based solutions to secure our future. It is biodiversity that will restore our degraded lands and polluted rivers and oceans and sustain our agriculture in the face of climate change. It is biodiversity that will form the basis of a new sustainable green economy. And it is biodiversity that will inspire our children to opt for a more humane, just, and hopeful future, which accords primacy to the living world.
Despite the importance of biodiversity that ultimately sustains all human endeavours, we have been poor stewards for caring and nurturing life on earth. Globally as well as in India, we have failed to adequately conserve and manage our precious, irreplaceable natural heritage. Biodiversity is declining worldwide, and our last remaining, largely isolated ecosystems are degrading due to changes happening around them, such as loss of species, climate stressors, and continuous human pressures.
