If we don’t take care of our planet, then no one will take care of it.
I believe that it is very important to take care of our planet, since if we don’t , the ones that will get affected is going to be us, the human beings.
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions.
The cause of global warming is the combination of several things.
One of the causes is human activity like industry, which causes pollution in the air, ground and water. Another cause is the waste of energy; we don’t take care of it at all, which causes gases, heat, and pressure. Another reason is deforestation, because fewer trees mean less carbon dioxide conversion to oxygen. And as a result of this kind of things that are very common the greenhouse effect doesn’t work as it should be working. Greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absorbed and the earth would be extremely cold. When too many rays are absorbed, the earth’s atmosphere starts to warm, which leads to global warming.
Global warming can lead to many problems that affect the environment in which we live. As I already explained the trapped heat changes the climate and alters weather patterns, which may hasten species extinction, influence the length of seasons, cause coastal flooding, and lead to more frequent and severe storms.
I will tell a few examples just of how global warming is affecting us or will affect us more in the future:
After existing for many thousand years, the northern section ice shelf in Antarctica (section bigger than Rhode Island) collapsed between January and March 2002, disintegrating at a rate that astonished scientists.
In 2005, scientists reported that some polar bears are drowning because they have to swim longer distances to reach ice floes. Now they are being considered for listing under the Endangered Species.
Hot, dry weather led to a record-setting 2006 wildland fire season with close to 100,000 fires reported and nearly 10 million acres burned.
In July 2006, severe heat waves in North America contributed to the deaths of at least 225 people.
In Ice Bay, Alaska, was filled with ice, but now, we only have a lot of ice water.
Global sea level has already risen by 4 to 8 inches in the past century, and the speed of sea level rise appears to be accelerating. Scientists predict that sea levels could rise 10 to 23 inches by 2100, but in recent years sea levels have been rising faster than the upper end of the range predicted.
This topic got my attention because I think that is a problem that is affecting our lives every day; there are drastic changes in the weather, and not only here in Hermosillo, in everywhere! That is why I want to talk about this, because I want to tell everyone that we must change our bad habits of contaminating our planet, or not taking care of the energy. There are simple things that we can do that can help our planet in a big way! Like using a compact fluorescent bulb which saves 300 lbs. of carbon dioxide. Keeping your tires inflated, which saves 250 lbs. of carbon dioxide. Use recycle papers, for each paper you save 5 lbs. of carbon dioxide. Take shorter showers. Buy products with less packaging and recycle paper, plastic and glass. Plant a tree: trees suck up carbon dioxide and make clean air for us to breathe. Un-plug electronic devices: even though that they are off they are using energy. Instead of using plastic bags for market get your own cloth bag. Turn off the computer or TV when you are not using it. Use a bicycle instead of a car 2 or 3 days. Picking garbage of dirty places won’t hurt you too.
As I explained there are many ways to avoid global warming, the problem is that no one cares. If someone starts contributing with this problem then maybe in the future the planet will be better. That´s why I wanted to write about global warming because at the end, if we don’t stop polluting and hurting our planet, the only ones who will get affected is going to be us.
