Endangered Species

The world is home to millions of species, but many are at risk of disappearing. Scientists estimate that over 40% of the planet’s species are threatened, with some, like the Javan rhinoceros, having fewer than 80 individuals left in the wild. Between 1970 and 2020, over 500 species, including the passenger pigeon and the western black rhinoceros, were declared extinct. Habitat loss, climate change, and poaching are major causes of this decline.

When a species goes extinct, we lose more than just an animal or plant. Each species plays a unique role in its ecosystem. For example, the sea otter, found along the Pacific coast, is vital to kelp forests. Sea otters eat sea urchins, which, if left unchecked, can destroy kelp. The term “keystone species” is used to describe creatures like the sea otter because their presence supports the balance of their environment. Losing them can cause ecosystems to collapse.

Efforts are underway to protect endangered species. In India, conservation programs have increased the population of the Bengal tiger from 1,400 in 2006 to over 3,000 today. Local communities are involved in these efforts, learning to coexist with tigers to reduce human-wildlife conflict. Similarly, in Australia, the government has set a goal to prevent any further extinctions of native species by 2030.

Technology is also aiding conservation. The International Union for Conservation of Nature (IUCN) has developed a digital Red List, an online database that tracks the status of species worldwide. This tool allows scientists, governments, and the public to access up-to-date information about threatened species, helping them make informed decisions to protect biodiversity.
