With every extinction, we lose not just a species but a treasure trove of knowledge

The planet is currently experiencing what scientists term the 'sixth mass extinction event,' a crisis unparalleled in human history due to its speed and primary cause: human activities. While Earth has witnessed five major extinction events over geological time, each leading to the loss of 70-95% of species, the current episode is unique because it is driven overwhelmingly by anthropogenic factors rather than natural phenomena. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Global Assessment Report of 2019 starkly warned that approximately one million species are now facing extinction, many within decades, a rate thousands of times higher than the natural background rate.

This alarming loss of biodiversity stems from a confluence of human-induced pressures. Habitat destruction and degradation, primarily through deforestation for agriculture, urbanization, and infrastructure development, is the foremost driver. Climate change, leading to altered habitats, extreme weather events, and ocean acidification, pushes species beyond their adaptive capacities. Pollution, ranging from plastic waste in oceans to industrial chemicals in ecosystems, poisons and disrupts natural processes. Overexploitation of resources, including unsustainable fishing, hunting, and logging, depletes populations faster than they can recover. Lastly, the introduction of invasive alien species outcompetes native flora and fauna, often leading to their decline or extinction.

Key stakeholders in this crisis are diverse and interconnected. Governments, both national and local, play a crucial role through policy-making, legislation, and enforcement of environmental regulations. International organizations like the United Nations Environment Programme (UNEP), the Convention on Biological Diversity (CBD), and IPBES facilitate global cooperation, research, and setting targets. Non-governmental organizations (NGOs) such as WWF, Greenpeace, and the Wildlife Trust of India are vital for advocacy, on-ground conservation efforts, and raising public awareness. The scientific community provides critical data, research, and solutions. Indigenous communities, with their deep traditional ecological knowledge, are often frontline custodians of biodiversity. Finally, industries (agriculture, mining, forestry, energy) and consumers, while often contributors to the problem, also hold the potential to shift towards sustainable practices and demand eco-friendly products.

For India, a megadiverse country home to four of the world's 36 biodiversity hotspots (the Himalayas, Western Ghats, Indo-Burma region, and Sundaland), the extinction crisis carries profound implications. India harbors 7-8% of the world's recorded species, making its biodiversity a global treasure. The loss of species directly impacts ecosystem services crucial for human well-being: clean air and water, pollination for crops, soil fertility, and natural pest control. This has direct economic consequences for sectors like agriculture, fisheries, and tourism. Socially, indigenous and forest-dependent communities, whose livelihoods and cultural identities are intricately linked to biodiversity, are disproportionately affected. Furthermore, the extinction of species means an irreversible loss of potential scientific discoveries, including new medicines, genetic resources for crop improvement, and insights into ecological resilience.

Historically, India has a rich tradition of environmental reverence, but rapid development post-independence has also led to significant environmental degradation. Recognizing the urgency, the Indian Constitution includes provisions for environmental protection. Article 48A, a Directive Principle of State Policy, mandates that "the State shall endeavour to protect and improve the environment and to safeguard the forests and wildlife of the country." Furthermore, Article 51A(g) establishes it as a Fundamental Duty of every citizen "to protect and improve the natural environment including forests, lakes, rivers and wildlife, and to have compassion for living creatures." These constitutional directives are buttressed by significant legislation such as the Wildlife (Protection) Act, 1972, the Forest (Conservation) Act, 1980, and the Biological Diversity Act, 2002, which aims to implement the provisions of the CBD in India. India is also a signatory to international agreements like CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) and the Ramsar Convention on Wetlands.

Looking ahead, the future implications are dire if current trends continue. We face potential ecosystem collapse, reduced resilience to climate change, increased incidence of zoonotic diseases, food and water insecurity, and a permanent reduction in Earth's natural heritage. However, there is also a growing global recognition of the crisis, leading to increased calls for conservation, sustainable development, and a shift towards a circular economy. The UN's Sustainable Development Goals (SDGs), particularly SDG 15 (Life on Land) and SDG 14 (Life Below Water), provide a framework for global action. India's commitment to these goals and its national policies on biodiversity conservation will be critical in mitigating this crisis, not just for its own sake but for the entire planet. The challenge lies in balancing developmental aspirations with ecological imperatives, ensuring that the 'treasure trove of knowledge' embodied in every species is preserved for future generations.
