Polar Bears And Climate Essay

Climate change refers to the variations in the mean and variables of climate properties that persists over long periods and results in one among the most crucial and common problems in the 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 causes tremendous spread of certain infectious diseases and increased death rates related to heat waves. Climate change would affect the health conditions of polar bears through malnutrition, high death rates, and frequent occurrence of diseases and injuries due to extreme changes in weather. In addition, high concentration of ozone gases at ground level causes cardio-respiratory diseases in urban areas (Richard, 2009).
In summary, climate change has physical and social effects on both human being and animals. The physical effects include increased temperatures, famines, high precipitation, and high sea levels. On the other hand, social effects include low food production due to high temperatures, spread of diseases and many others. The effects are unlikely to reduce unless a quick action is taken to curb the adverse climatic changes.
In the wild, polar bears typically live to be 20-30 years of age. Both females and males mature at the age between four and five years. Females regularly conceive their first litter of offspring when they are at maturity stage, while males do not generally begin mating until they are between eight and ten years of age. Mating happens in April to May, but delaying implantation, the fertilized egg cease developing at the early stage, implies that fetal formation does not start until September-October. What is to come for the polar bear is affected by various variables, for example, environmental change, ecological poisons, and the food they consume.
The populaces of polar bears living most remote to the north (in the northern Greenland, more distant to the north, and Canadian Arctic Islands) have really seen populace builds lately and may survive inconclusively (Peacock 2013).Nevertheless, they will be at danger from continued change in climate; contaminants in the Arctic; expanded infection chance; and diminished hereditary differences (Stirling 2012).
Throughout late fall, females polar bears go into hibernation and stay there around four months. At the start of January, between one and three cubs are conceived depending upon the age of mother and condition. The infant offspring are amazingly little, weighing just about half a kilo, yet they develop quickly because of the high fat substance of their mother's milk. The offspring stay with the mother until they are more than two years of age. The newborn child death rate is high and can surpass 70%. Just around a third of offspring reach two years.

Global Warming: Humans Are Destroying the Planet

1645 words - 7 pages Everyone knows that global warming is a serious environmental health problem with its effects reflecting on nature and all of mankind on Earth since the mid-twentieth century – emission of concentrated greenhouse gases, rise of sea levels, melting of polar ice caps, and increase in global surface air temperature. The rise in global surface air temperature causes frequent droughts in dry areas and accelerated ocean warming and hence the rapid...

Essay Title: Polar bears are endangered
Polar bears are one of the countless species who are endangered. They were one of the first animals affected by global warming and their population is heavily decreasing. Around 1980, the Arctic was as large as 8 million square kilometres. In 2011, studies show that the Arctic has reduced its size to 4.5 million square kilometers. In the future, will there be anything such as the Arctic? Scientist predict by 2040, only a fringe of ice will remain in Northeast Canada and Northern Greenland. This is known as the Last Ice Area. This matter is mostly taking part in Canada, since; Canada holds more than half the world’s polar bear population. Other affected countries include the U.S. (Alaska), Greenland,…show more content…

Other affected countries include the U.S. (Alaska), Greenland, Russia, and Norway (the Svalbard archipelago) .There are solutions to slow down global warming but unless we all act together, then there is no hope for the polar bear inhabitants of earth.
CAUSES OF THE PROBLEM
Polar bears are endangered animals as a result of the humans polluting their environment. Human hobbies such as hunting destroy polar bear population. Some cultures find polar bears as good sources of food. But, the leading reason behind polar bears endangerment is global warming. Global warming is destroying the polar bear habitat. Global warming is caused by humans but we are not making an effort to fix it. A lot of humans still do not even know what global warming is and should be aware of this issue. The main cause of global
