Leave it to Beavers w/Eng sub file

Nature’s greatest hydro-engineers transform landscapes.
Learn how beavers are being recruited to reverse the effects of global warming and water shortages.

A growing number of scientists, conservationists and grass-roots environmentalists have come to regard beavers as overlooked tools when it comes to reversing the disastrous effects of global warming and world-wide water shortages. Once valued for their fur or hunted as pests, these industrious rodents are seen in a new light through the eyes of this novel assembly of beaver enthusiasts and “employers” who reveal the ways in which the presence of beavers can transform and revive landscapes. Using their skills as natural builders and brilliant hydro-engineers, beavers are being recruited to accomplish everything from finding water in a bone-dry desert to recharging water tables and coaxing life back into damaged lands.
