who dies when sea levels rise?


Who dies when sea levels rise?

By Abbie Harold & Katriel Perry

Years ago we didn't have to worry about how to cut down on fossil fuels or green house gases to help reverse the process of global warming. All we cared about was ourselves and how we were supposed to live our lives. We had no care in the world what other people where doing. We never stopped to look back and see what we were doing to the plants and animals of the earth, and when we finally did it turned into one of the biggest problems we have ever had to face.

The Webster dictionary defines Fossil fuels as "carbon-rich fuels like (coal, oil and natural gas) formed from the remains of ancient animals and plants." The Webster dictionary also defines gases such as water vapor, carbon dioxide and methane as Green house gases. The two major chases of global warming are green house gases and fossil fuels. Green house gases are making it so the heat from the sun is unable to go back out of the earths atmosphere, witch is slowly rising the overall temperate of the earth. As solar radiation passes through the plants atmosphere, witch contains greenhouse gases, the radiation warms the surface of the earth and heat rises from it. Some of the heat is able to pass back through the gases, and some heat just can't pass back through, and it remains in the atmosphere. This adds to the overall temperature of the earth.

Climate change is affecting the oceans tremendously. Global warming has caused glaciers to melt into the ocean, resulting in the constant rising of the sea leaves over a period of time. The rising of sea levels will affect not only the ocean but people. Al Gore believes that by the time 2020 land at lower elevations or sea side houses will be flooded.


People aren't the only ones that will be affected by global warming and climate change in the ocean, marine plants and fish will suffer too. There are so many fish and plant species that live in the depths of the ocean that scientists have not even discovered yet. Because of the effects that global warming has already put upon the ocean many of those species that we have never seen might have already died from the slit change in temperature in the ocean.



Mammals like polar bears and birds are also being affected. Al Gore believes that if global warming continues, The Arctic Ocean could be ice free in summer by 2050. With the strange weather that global warming is changing the season that polar bears usually feed in is shortened. This makes it hard for polar to eat, which eventually kills them. More than a million species of animals worldwide could be driven to extinction by 2050. This is a huge loss of animals in the somewhat short time period of about 40 years.

How can we reduce the amount of fossil fuels and green house gases released into the atmosphere?


There are many ways you can reduce the fossil fuels and greenhouse gases you omit into the environment. Transportation of foods releases lots of fossil fuels. If we all started growing our own food and eat locally it would save a lot of oil. Most of our appliances take a lot of energy to run. If we all started to buy energy efficient ones it would save us money and be less hard on the environment. We can also uses public transportation, carpool and walk. If we did that it would get more people around in the same amount of gas. Not as much pollution is going into the environment.
