Earth Science

At present , the earth is in the midst of a crisis . Due to human activities which atomic number 18 unmindful of environmental considerations , the satellite is now in danger . These activities threaten the existence of the human race , as well as all the creatures in it . devil of the main environmental concerns right now are humor convert and globular warming These phenomena are very authoritative in altering the ways people and animals live . wiz species that is greatly affected by the interpolates are the penguinsClimate swop and spherical warming are two distinct phrases which are link to each other . The terms mode change and global warming are often interchanged , but their definitions are really different (U .S . Environmental Protection Agency [EPA] , 2008 . Climate change refers to the modifications in the climate of the earth . The change is manifested in the determinants of climate , which include wind precipitation and temperature . Climate change usually extends over a long period of time . thither are many factors which cause climate change these factors are inherent and human . Natural factors which cause climate change include a change in the earth s cranial orbit or the force of the sun . Human factors , which account for the real climate change include deforestation and the burning of fogey fuels (EPA , 2008Meanwhile , global warming is the average increase in the temperature of the ambience near the Earth s surface and in the troposphere , which can tolerate to changes in global climate patterns (EPA , 2008 . It is similar to climate change in the sense that it is also caused by both natural and human factors . theless , global warming is often attributed to the greenhouse splatter emissions which result from human activities (EPA , 2008Climate change has had a huge impact on various animal populations Global warming in particular has had a tremendous effect on animals rigid in the poles . One animal species which is directly affected by climate change are the penguins .

As reported in the National Geographic News , climate change is liable for the decline in penguin populations for the past fifty years (Roach , 2001 . For representative emperor penguins in the Antarctic have reduced in number due to the lengthy warm spells . The increase in temperature resulted in the decrease of krill , which is a significant part of the pabulum of the emperor penguin . If the food is non sufficient , the penguins will travel (Roach , 2001On the contrary , another source states that the population of the emperor penguin did not experience a significant decrease , as exhibited in the area of Taylor Glacier ( Penguin n .d . In addition , it is also implied that not all penguin species are negatively affected by the global warming . For instance , Adylie penguins need land surfaces without ice to get their nests . Global warming causes glaciers to recede the recession of the glaciers is advantageous to the Adylie penguins because it allows the constitution of colonies . The recession of glaciers also result in the abundance of the moraines , have words rocks which the Adylie penguins...If you want to get a full essay, order it on our website: Orderessay
