These cute rodents will amaze you. Don’t miss this Documentary. Understand the nature and coexistence lessons from the Beavers.
Beaver dams are dams built by beavers to provide ponds as protection against predators such as coyotes, wolves, and bears, and to provide easy access to food during winter. These structures modify the natural environment in such a way that the overall ecosystem builds upon the change, making beavers a keystone species. Beavers work at night and are prolific builders, carrying mud and stones with their fore-paws and timber between their teeth. Beavers can rebuild primary dams overnight, though they may not defend secondary dams as vigorously.
Note: Since this is just an average life expectancy, no doubt you will always have some exceptions. You will definitely have a few animals exceeding their life span.
Some animals life span might seem very short while others are reasonably long when compared to other animal species. However, the average life expectancy of a given animal is determined by factors such as genetic makeup, metabolic rate, body size, age of sexual maturity etc. It is important to note also that some domesticated animal can live longer or shorter than if they were living in their natural environment (habitat). The reason for this may due to conditions such as new lifestyle, change of diet, disease, predator (absent), etc. Therefore, in spite of the fact that many of these values given in the list below are based on the records taken from various sources, it should not be seen as the absolute maximum lifespan.

“Beavers cause global warming!” says Scientists! (Excerpts: Facts)
When it comes to transforming their environment, beavers have a lot in common with humans. They clear-cut trees and build dams to block streams, in the process radically altering the world around them. Now, it appears that beavers play a complex role in climate change, too. A new study suggests that beaver dams and the sediments corralled behind them sequester carbon, temporarily keeping greenhouse gases containing the element out of the atmosphere. But when the animals abandon these sites, the carbon leaks back out, contributing to global warming.
Today, abandoned beaver meadows contain about 736,000 metric tons of stored carbon—about 8% of the total stored in the soils of these watersheds. But if all the beaver dams were occupied with their wetlands intact, her previous data suggest, beaver meadows would be storing about 23% of the landscape’s soil carbon, an estimated 2.7 million metric tons of organic carbon.
Beaver ponds can indeed be large sources of potent planet-warming greenhouse gases such as methane and nitrous oxide
