Polar bears at risk
Polar bears live only in the northern Arctic where they spend most of their time on ice floes. Today, polar bears are decreasing rapidly. Nowadays, scientists predict that bears could disappear by 2050. The global warming, hunting and organic pollutants are the most important causes of death of polar bears.
One of the main causes of the death of polar bears is the global warming. The global warming is very dangerous because it increase temperatures of ocean water. Accordingly, sea ice has shrunk. Thus, marine animals like seals or bears should change their ecosystem. Under these conditions, human being and marine animal will share an ecosystem.
Another important cause is illegal hunting. The hunt of polar bears is alarming because it causes a direct death and reduction in the population of these animals. Also, it is increase because of obtain a reward. Also, illegal hunting has unbalanced the animal species. As a result, several animals have problem to reproduce. Hence, many animals are in danger of extinction.
The latest cause most important in the death of polar bears is organic pollutants. It is critical in the death of polar bears because it contaminates their habitat which is the arctic sea. If the sea is contaminating, animals like fish could die. Consequently, if fish die, polar bears could not eat it, and if they don´t eat, they could die.
Humans should protect polar bears, because it is possible for them to do. A request for save the polar bears is planting a tree; it is for help stop the global warming. Another petition is stop the hunting of these animals. Also, we have to stop buying pesticides because it is contaminating the seawater. In those ways, we should try to help and protect the polar bears. We have an obligation; save the polar bears.
