(CLAIM) HEADLINE: "Polar bears really are starving because of global warming"
(EVIDENCE 1) Polar bears use 60% more energy searching for and catching seals according to a study. EVIDENCE 2: In the same study, 4 out of 9 bears lost 10% or more of their body mass in a 11 day study.
REASONS WHY: Factories and human in cities and towns far from the arctic are changing the climate as a result of fossil fuel burning. The CO2, CH4, and NO2 pollutants put into our atmosphere change the concentrations of these molecules that trap radiation in our atmosphere and send heat back to earth, rather than letting it escape back to outerspace where it belongs.
The outcome is higher average temperatures on Earth. Since Polar Bears need sea ice to hunt seals which make up 95% of a seals' food, with longer summers, the arctic's ice is not frozen as long, meaning bears have to swim more to find food.
EVIDENCE: "sea ice is melting by 14% each decade due to global warming'. With melting land ice due to increased warming, seas are rising, ice is shrinking.
SOLUTION: Humans need to balance artificial emissions. Technology and help https://news.nationalgeographic.com/2018/02/polar-bears-starve-melting-sea-ice-global-warming-study-beaufort-sea-environment/
