Polar bears find themselves in a battle with humans over their main food source. With locals killing seals for food and fur, the polar bears are finding it more and more difficult to hunt. We must enact stricter hunting regulations to save the seals, which will, in turn help to save the polar bears.
Before the majestic animals of the Arctic become extinct, people must work hard to drop their greenhouse gas emissions, including driving less and recycling more. Only by reversing the damaging effects of greenhouse gasses can the animals of the Artic be saved. We must step up and do our part to help save the planet.
The effects of global warming and climate change are seen in a chain-reaction in nature. The melting of the ice creates a struggle for the seals as they seek a safe place to raise their young, and with fewer seals that are more difficult to find the polar bears are starving. The ecosystem is all interrelated and global warming shows us just how delicate a balance it is.
Scientists are still working to understand the effects of global warming and climate change. In Australia, as climate change sparks huge and destructive wildfires, the eucalyptus trees native to the area are being destroyed. This, in turn, has a huge impact on another bear, the koala bear.
