Across the world, wildlife is under severe threat. Wildlife population sizes dropped by 68% between 1970 and 2018. Species are becoming extinct quicker nowadays than ever before. Biodiversity is vital to the health and livelihoods of the planet’s eight billion people.
Will all wildlife go extinct?
These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. If the low estimate of the number of species out there is true – i.e. that there are around 2 million different species on our planet** – then that means between 200 and 2,000 extinctions occur every year.
Why wildlife is getting extinct?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Dinosaurs, for instance, lost their habitat about 65 million years ago.

Are we going extinct?
Current population predictions vary. But the general consensus is that it’ll top out sometime midcentury and start to fall sharply. As soon as 2100, the global population size could be less than it is now. In most countries—including poorer ones—the birth rate is now well below the death rate.
What we lose when animals go extinct?
Habitat loss—driven primarily by human expansion as we develop land for housing, agriculture, and commerce—is the biggest threat facing most animal species, followed by hunting and fishing. Even when habitat is not lost entirely, it may be changed so much that animals cannot adapt.
Are extinctions necessary?
Extinction is the dying out of a species. Extinction plays an important role in the evolution of life because it opens up opportunities for new species to emerge.
What are the 5 causes of extinction?

- Destruction of wild habitats.
- Introduction of invasive species.
- Climate change.
- Hunting and illegal trafficking.
