- Habitat loss: The destruction of an animal's natural habitat can make it difficult for the animal to find food, shelter, and mates. This can lead to population declines and eventually extinction.
- Hunting and overexploitation: Humans have hunted animals for food, fur, and other resources for centuries. Unsustainable hunting practices can deplete animal populations and lead to extinction.
- Pollution: Pollution can contaminate air, water, and food, making it difficult for animals to survive. This can also disrupt the food chain and lead to population declines.
- Climate change: Climate change is causing the Earth's temperature to rise, which can alter weather patterns and disrupt animal habitats. This can make it difficult for animals to find food, shelter, and mates, leading to population declines.
- Invasive species: Invasive species are non-native species that have been introduced to an area outside of their natural range. These species can compete with native animals for resources, such as food and habitat, and can also transmit diseases. This can lead to population declines and eventually extinction of native species.
- Disease: Diseases can spread rapidly through animal populations and cause widespread mortalities. This can lead to population declines and eventually extinction.
Organisms become extinct when they can no longer adapt to the changing conditions in their environment. This can be due to a variety of factors, including climate change, habitat loss, pollution, hunting, and disease. When an organism can no longer survive and reproduce in its environment, it will eventually become extinct.
