My favorite animal

Mi favorite animal is the beaver. This is my favorite animal because I think that they are very smart and beautiful. There are three types of beaver: beaver fiber (or European beaver), the beaver canadensis (or American beaver) and beaver californicus (or beaver accuser). 

The people know the beaver for its ability to build dams, they used to construct branches of trees that they cut with his teeth.
One of the things that I like about these animals is that despite the large number of trees that they cut, they not harm the ecosystem in which they live, unlike the human being that sweeps to a dam with a number of impressive ecosystem. 

Although the beaver is an excellent swimmer, it's pretty clumsy when moving along the ground, and find so difficult drag the logs and branches you need it is quite hard to drag the logs and branches you need to feed and to build their burrows. So it is easy to finding in colonies of beavers roads constructed by them in direct communication with the lake nearest trees in order to make them easier for the transfer of the branches they use.
