Q.National parks and sanctuaries are established for the purpose of:

Think of biodiversity as the planet’s insurance policy. When you walk into a forest, you don’t just see trees — you see a web of living things that depend on each other, from the soil bacteria to the birds overhead. Conservation is the deliberate act of protecting that web, not because it’s pretty, but because our own survival is tied to it. For a commerce or humanities student, the easiest way in is through money and risk: every crop we grow, every medicine we discover, every clean water source we rely on — all of it traces back to biodiversity. Lose the web, and you lose the raw materials for future business, future health, and future stability.

Biodiversity conservation scope is simply the full range of what we try to protect and how. It’s not just about saving pandas or tigers. The scope covers three levels: genes, species, and ecosystems. Genes are the building blocks inside every organism — the reason wheat has thousands of varieties, each with different resistance to pests or drought. Species are the individual kinds of plants, animals, fungi, and microbes. Ecosystems are the larger communities — a mangrove swamp, a grassland, a coral reef — where species interact with each other and their physical surroundings. Conservation at one level often supports the others. Protect an entire wetland, and you automatically protect the fish, the birds, and the genetic diversity within them.

Why does this matter to someone who will never step into a rainforest? Because the scope also includes why we conserve. There are two broad reasons, and they’re not mutually exclusive. The first is utilitarian — biodiversity is a resource. Timber, fisheries, pollination for agriculture, natural flood control, even the genetic material that pharmaceutical companies use to develop new drugs. The second is ethical or intrinsic — every species has a right to exist, regardless of its usefulness to us. A humanities student will recognise this as a values question: do we protect nature because it serves us, or because it has worth in itself? Most real-world conservation policies blend both.

The practical scope of conservation is usually divided into two approaches. In-situ conservation means protecting species in their natural habitats — national parks, wildlife sanctuaries, biosphere reserves. This is the most effective because it preserves the entire ecosystem, including the interactions between species. Ex-situ conservation means protecting species outside their natural homes — seed banks, botanical gardens, zoos, captive breeding programmes. This is a safety net, not a solution. You use it when a species is on the brink and its habitat is already destroyed. A good conservation strategy uses both, because they solve different problems. …
