Beneficial Beavers

Most people have some familiarity with beavers, whether in person or seeing them on television. Some folks consider them pests. After all, they gnaw down trees, build dams, and interfere with the flow of water. This can get out of hand without predators to keep them in check. However, these (mostly) Northern Hemisphere rodents are actually good for the soil.

Beavers are important for the environment and many ecosystems.

Pollutants such as nitrogen and phosphorus get trapped into the ponds that were the result of beaver dams. Also, other critters benefit from the ponds, and help deter soil loss. If you read up on beavers, you'll see that the Master Engineer designed them for what they do so well. Of course, Darwinists will lasso the "EvolutionDidIt" non-explanation by rote, but that nonsense only contaminates the good soil of actual science. 
Without beaver dams, loss of nutrients from soil would increase, and pollutants from upstream erosion would afflict waterways.

Scientists at the University of Exeter looked into the beneficial functions that beaver dams perform for soil and rivers. Look how much one family of beavers can do:
