There are a number of potential causes of extinction. One of the most well-known is habitat loss, which can occur when a species' natural environment is destroyed or degraded to the point where the animals can no longer survive. This can be caused by human activity, such as deforestation, or by natural disasters, like wildfires. Another potential cause of extinction is overhunting, which occurs when a species is hunted to the point of extinction. This can happen for a number of reasons, including sport, commercial trade, or even as a form of population control. Additionally, some species are at risk of extinction due to disease. This can be caused by the introduction of a new disease to which the animals have no immunity, or by the spread of a disease to new areas where the animals have not been exposed to it before. Finally, climate change can also cause extinction by making an environment unsuitable for a species to live in. For example, rising temperatures can cause a species to lose its food source, or make its habitat unlivable.
