Next to the spider, beavers are one of the most impressive architects in the animal kingdom. What is interesting about them is their ability to manipulate the environment they live in to create ideal living conditions. Not only will they destroy trees, but they carry large amounts of branches and twigs, combining them with mud to form a strong wall. 

These lodges are solid enough to last for 10 or more years. That can be as long as the life of the beaver itself. These lodges are also a safe space for them because they can hinder predators from accessing them as easily.

Back to the initial inquiry about why beavers cut down so many trees; these semi-aquatic mammals’ front teeth grow continuously. Apart from building dams, gnawing on trees is essential for them to maintain their teeth.

Beavers are not only architects, but they are also family-oriented. It is believed by some scientists that male beavers build dams to impress a female beaver they’re interested in. Once they match, they are often monogamous. They will usually live with their entire family in the same dam until the kits grow old enough to move out and begin reproducing.
