Answer
One major human activity that has contributed to global warming is the burning of fossil fuels. This process releases significant amounts of carbon dioxide and other greenhouse gases into the atmosphere, leading to an increase in global temperatures.

Answer
A significant consequence of rising sea levels on coastal areas is flooding. As sea levels rise, low-lying coastal regions become more susceptible to inundation, which can damage infrastructure and displace communities.

Answer
One adaptation of polar bears is their white fur, which provides camouflage in their snowy habitat. Additionally, they have a layer of fat under their skin that helps insulate them against the extreme cold.

Answer
I would expect the population of polar bears to decrease as ice sheets melt. The melting ice reduces their habitat and hunting grounds, leading to food scarcity and lower survival rates.
