Polar Bears and Climate - 1675 current world. Often, climate change results from human activities or natural gases and has both physical and economic effects on the world and people. Climate change has social effects on aspects such as health, food production and growth. Climate change is causing a considerable spread of certain infectious diseases and an increase in death rates linked to heat waves. Climate change is believed to affect the health status of polar bears due to malnutrition, high mortality rates, and the frequent occurrence of diseases and injuries due to extreme climate change. In addition, the high concentration of ozone at ground level causes cardio-respiratory diseases in urban areas (Richard, 2009). In summary, climate change has physical and social effects on humans and animals. The physical effects include increased temperatures, famines, heavy rainfall, and rising sea levels. On the other hand, the social effects include low food production due to high temperatures, the spread of diseases, and much more. others. The effects are unlikely to diminish unless rapid action is taken to curb adverse climate change. In the wild, polar bears typically live between 20 and 30 years. Females and males reach maturity between four and five years of age. Females regularly conceive their first litter when they are in the mature stage, while males usually do not begin mating until they are eight to ten years old.
