• 16．This woodland construction is the world's biggest beaver dam，which at 2，790 feet in length and more than twice the length of the Hoover Dam，and can be seen from space.
     The mammals use trees，mud and stones to make a type of moat（壕溝）where they can use their swimming skills to evade（躲避）any predators（食肉動物）.The families of beavers live in lodges on the dams and spend their days adding to and repairing the incredible structures.While beaver dams are often found to be around 1，500 feet in length，this one has surprised biologists because of its length.The dam is located on the southern edge of Wood Buffalo National Park in northern Alberta，Canada.It is thought that several beaver families joined forces to create the big dam that contains thousands of trees and must have taken many months to complete.
     The dams are an important part of the ecology and wider environment，and climate change can be judged by the spread of the dams.
     Sharon Brown，a biologist from Beavers：Wetland and Wildlife，an educational organisation in North America，said："Beavers build dams to create a good habitat.They are very agile（靈活的） in the water，but they're a bit slow moving on land."
     "They create a habitat with lots of water，like a moat，around their lodges so they can swim and dive，and keep one step ahead of predators."
     "They also use water to move the trees they use in their dams，because it is easier floating branches on the water than dragging them over land."
     "Their dams are also beneficial because they slow the flow of water leading to less drought and less flooding.And when plant matter dies in water，it turns into peat（泥炭） and that is one of the best ways for storing carbon dioxide."
