extinct

Extinct means that a species of plant or animal no longer exists. There are no more living members of the species.

Extinction can happen for a number of reasons, including:

• Overhunting: Humans have hunted many species to extinction, including the woolly mammoth and the passenger pigeon.
• Habitat loss: When humans destroy the habitat of a species, the species can no longer survive. For example, the destruction of rainforests has led to the extinction of many species of plants and animals.
• Climate change: Climate change can also lead to extinction. For example, the extinction of the dodo was caused by a combination of overhunting and climate change.

When a species goes extinct, it is a loss to the entire planet. Each species plays a role in the ecosystem, and when a species goes extinct, it can disrupt the entire balance of nature.

The dodo is an extinct bird.
