* Hunting: Wild animals are hunted for food, fur, or sport. Hunting can be done legally, with a license, or illegally, without a license.
* Trapping: Wild animals are trapped for their fur, meat, or to be used as pets. Trapping can be done legally, with a license, or illegally, without a license.
* Predation: Wild animals are killed by other animals as part of the food chain. Predation is a natural process, but humans can sometimes interfere with it by introducing new predators into an ecosystem or by protecting prey species from predators.
* Disease: Wild animals can die from diseases, either natural or introduced by humans. Diseases can spread quickly through a population of wild animals, and can sometimes even lead to their extinction.
* Habitat loss: Wild animals can lose their habitat due to human activities, such as development, logging, or mining. When wild animals lose their habitat, they may be forced to move to new areas where they are not as well-suited to survive, or they may simply die.
* Climate change: Climate change is causing the habitats of wild animals to change rapidly, which can make it difficult for them to survive. Wild animals that are adapted to a particular climate may not be able to survive in a new climate, and may eventually die.
It is important to remember that wild animals are an important part of the ecosystem, and that their killing can have a negative impact on the environment. It is also important to remember that wild animals are sentient beings, and that they deserve to be treated with respect.
