Polar bears depend on ice because their main source of food is seals and they need to rest on ice to wait for seals. Although they are strong swimmers there have been reports of polar bears drowning because they could not find any ice to rest on.
Hundreds of millions of people also depend on ice but they don't even know it. All of the people who use water that comes from melting glaciers depend on this melting to irrigate farmland. This include people in North America who use water from rivers that rely on melting ice in the Rocky Mountains. It includes hundreds on millions of people that now rely on water from melting glaciers in the Himalayan mountains. In just 50 short years many people will not have the water they need if current ice melting rates continue because the glaciers will be all gone.
No governments are preparing for this eventuality, in fact the populations and demand for water are increasing. Unless humanity starts doing things differently great tragedies will occur. Too bad that Obama is spending so many trillions to get back to where we were when that was obviously a bad place to be.
