What climate change is doing to the environment is saddening yet dangerous, a lot of people in the world really don’t think its a threat and are blindsided of long term effects if nothing is done about it. As you can see a polar bear which is supposed to be one the most dominant and power mammals in the arctic, is starving to death due to a lack of food. Just realize that if it impacts nature, it will pretty much affect humans in the long run, as nature was before us. And if were seeing what the effects are on a polar bear, just imagine what it would be with humans.
