orange group!: Mercury Affects Polar Bears

There are a few things humans can do to cut down the amount of mercury in the environment, such as using less power plants of eliminating some of the plants that produce chlorine. Many things can cause an excess in mercury, such as incinerators and power plants, but is also exposed during small-scale gold mining. This Mercury is being exposed to the polar bears, which are declining in number because of the plankton they eat that contains the mercury. In addition, Global Warming is also hurting the polar bears by melting of the ice. Unfortunately, the polar bears have to eat the plankton containing Mercury because the ice is melting and it is the only food they can eat.
