Why are animals going endanger?

Answer 1

Global warming is a factor when it comes to polar bears going endangered. The warmer climate that is caused by more energy, oil, coals to heat our cities the warmer the climate therefore as heat rises the earth core gets hotter and therefore the ice melts leaving the polar bears with less ice and more water, and although polar bears are excellent swimmers they have to swim over 50 miles to find seals which by that time seals can escape faster and polar bears are exhausted from there journey. This is why you see so many polar bears floating in the waters; mostly their cubs (die from exhaustion and lack of food). Seals (main food source) for polar bears were easier to catch when the seal had to come up for air (through the ice) the polar bear would wait and catch it, now they have to swim far away to find seals because there is less and less of ice.
