Polar Bears & Global Warming

Polar bears are drowning because of the Global warming due to sea ice is not forming. It is sad, what we have done caused others to suffer.... Can we really do something to change it? -------What can we do about the Global Warming? We can recycle more, reduce the waste, save energy by turning off lights, walk more, drive less, ride public transportation, drive energy saved cars, buy less, being vegetarians, and be mindful about what we can do to improve rather than doing noting. Do something even baby steps, we need to save our earth so not only polar bears can survive but our next generation will have a clean and safe place to live.
