Essay about endangered animals in 300 words
Answers
The Earth has already witnessed five mass extinctions and is going to experience more. More than 99 percent of total species, amounting to over five billion species that ever existed on Earth are estimated to be extinct, it is linked to habitat fragmentation and climate change. But there also are other hidden reasons underneath them. There is one reason that lies in the bottom of animal and plant extinction and poses the single greatest threat to the diversity of our planet. Habitat fragmentation is destructive change to landscapes and environment that is caused either by natural phenomena, such as floods, hurricanes, or human activities, such as deforestation and construction. Despite the process, the natural environment of a species becomes diminished or destroyed. Another cause of the extinction is climate change, which is the change in the average weather patterns, which can last for an extended period of time, like millions of years.. All this heat of the atmosphere, resulting in global warming that causes the world’s oceans to warm, as they absorb 80 percent of the additional heat, changes the global sea level.
Rising temperatures of the oceans directly affect the behavior and life cycle of marine species. Sea levels have been growing over the past century, and the rate has risen in recent decades. Increasing sea levels due to climate change may have a great influence on the coral reef ecosystem. The melting of the glaciers and ice sheets contributes to increasing the levels of the world’s oceans. It is affecting certain animal species at the North pole. One such species are the polar bears. They usually rely on the ice sheets that swarm on the Arctic sea to find their prey. Global warming is making the ice sheets to melt earlier every year, affecting the survival of the polar bears Scientists have predicted that the polar bears will not survive an entire loss of sea-ice cover during the summer. They also estimated that the population of the polar bears is of a little more than 20,000 and that this number could decrease by the year 2050.
Despite the reason why the endangered species become extinct, they are going extinct. And we need to figure out the solution to this ongoing problem in our society.
