The scientific community claims that two thirds of the mammal’s will disappear by 2050
Climate change has a faster and more severe effect on the Arctic biome when compared to the rest of the ecosystems. Studies have shown that the Arctic is warming twice as fast in comparison to the global average temperature.
Warmer temperatures end up melting ice caps which are the habitat of several species, including the polar bear. Although their reducing population crave an emotional response from many people, their disappearance on Earth will have terrible effects on the environment, as well as on the economy.
Keystone species are those capable of affecting an entire ecosystem. In this case, polar bears act as the apex of the arctic biome which puts them on top of the trophic chain. Due to their role on the Arctic ecology, the unique animals act as a population regulator to keep the environs in balance.
Changes in keystone components have a domino effect on the entire ecosystem. As ice caps continue melting, polar bears population reduces. When their main predator is rarely seen, artic seal number inflates changing the dynamic of the food chain. The overpopulation of said animals may trigger a distress in salmons as more seals need to be fed. This may also affect fishermen.
