Global warming affects of extinct penguins

In this article , "Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward,” the author reports that global warming pushes penguin populations southward'. The auther Lyons as saing in the Antarctic peninsula has penguin populations that are migrating south and perhaps diminishinh. He said temperature is increasing and changing along the Antarctic Peninsula. Lyons was one of the researchers who cares about penguin’s extinction and reporting about global climate threat during the annual meeting in San Francisco. He said the decrease in sea ice shows drop in krill in the marine area that reduce resource for mammals and birds. He paid attention to global climate change in the Antarctic and the level of sea ice decrease along its margins.

There are affects of the reduction in number of penguins around the world. However, the article paid attention to one important effects of global warming. It considered this dangerous for penguins and penguins’ environment that they live in. There are many causes of global warming, reasons it has increased and ways it affect penguins. So, the article pays attention to some results of global warming and how it affects of climate and temperature. There are many reasons penguins are becoming extinct and reasons they are being reduced. So, the answer is because of global warming's increase or change, penguins’ poles becoming sea, and human activitiesthat affect global warming.

First, global warming's first effect is the extinction of penguins because it makes percentage of temperature increase that affect of penguins' area Of course when global warming changes that means it affects weather and climate change. So, when they change the temperature increases in the atmosphere and penguins’ environment. Some causes of global warming change are natural events and human activities. Natural events affect global warming by changing and making temperature increase, which has a dangerous effect on earth species. one results is the reduction of sea ice and increase in the sea level because temperature increases. Some examples of natural events that affect change of global warming are volcano, earthquake, and fire in forests. So, global warming is considered the cause of penguins' extinction and people and government should work together control its.

Second, the percentage of sea increase in pole of sea ice that means level of water in the pole increase of level sea ice. Of course penguins live in pole. However, when the temperature has increase in the sea ice, that means level of the sea increase s of level sea ice in pole so, it is dangerous for penguins because poles have melts and convert to water and percentage of ice sea decrease and change to water . Some effects of poles melting are that make they leave poles to a new area there the percentage of ice is stout and has some animals that penguins eat. Another effect of poles melting is that the population of penguins decreases. So, the fact is that global warming again affects the poles to melt, makes the sea level increase at the poles, and makes some problems for penguins’ population decreasing.

Third, the global warming change because some human activities. Of course when people produce some items by use nonrenewable resources by factors which affect of global warming to change temperature and the results affect of penguins’ environment. Actually human activities esteem causes of the ecosystem to change and temperature changes to high . For example pollution has air and water. So in this case the important thing is water pollution, because penguins live on in the Ice Sea and they are affected by the spread of oil on the oceans. For example, when container ships transfer oil to any country and it gets damage, oil spread, inside the sea or ocean. In this case, water changes and all species and plants die because of pollution. Another example of human activities when factories produce smoke by using resources; that makes air pollution. So, it affects global warming by air pollution and produces a change of temperature and affects the penguins. some Human activities affect of global warming to produce high percentage of temperature increase that affect of penguins’ population to decrease.

In conclusion, global warming, human activities, and Level water in sea rising in the poles by high temperature all them are reasons to make penguins extinction. Also, when poles melt and makes penguins migrate. The last effect human activities are one of effects of penguins extinction. When people use recourse natural they produce some pollution that affects the penguins’ environment. So, people and government are liable to care about penguins' extinction and work together to find some solutions to protect penguins of extinct.
