Expanding the territory that people inhabit is less visible way of dog extermination. Cutting down forests and taking over habitats of dogs that live in wilderness does not only risk for canids, but for other beings living in that area, both on the ground and above it. It endangers their way of living and their survival. It endangers ecosystem. It increases the danger of extermination of certain species. In many areas, territory that dogs in wilderness can roam is getting smaller by day. Forests disappear due to cutting down trees for build or to make way for new roads and towns. Beside this, they get killed by farmers, which increases the number of executed animals.
Many regions where certain species lived, such as Ethiopian wolf also known as Simien jackal, are facing extinction because plains with high grass where they live are taken over by farmers for feeding their livestock. Wast areas where Red wolf and African Wild Dog live are now farms. Dhole and Bush Dog are becoming rare too, due to more land that is being cultivated. Human population is growing while the number of animals in the wild is reducing. Nothing but absence of wildlife in forests and hunger make animals get closer to human settlements.
As human settlements got wider, wolves were limited to remote, further places, such as far north. In the frozen wilderness of Arctic, Arctic wolves and Arctic foxes live, while there is small amount of humans. This is why these species are not endangered. This is clear example of how taking over a habitat becomes a threat for animal extinction.
