Climate change makes our market unstable and lower efficient, so food become much more expensive. Effects on animals are seriously. Polar bear can’t live because ice becomes less, the flooding of coastal estuaries by rising sea levels affect animals breed. Many species will be wiped out if global warming continues. They will loss habitat and food: melting the glaciers, high rate of evaporation, higher temperatures, frequent and severe droughts, reduced rainfall, and lower nitrogen content in forage
