Week Post Two: Impact on Humans

The ice caps are melting, the temperatures are rising, and humans are dying? Yes it’s true. Researchers say that 150,000 deaths every year are from global warming and they say that the deaths will double by 2030 even if people will try to reduce the amount of emissions being released. Because the weather is getting warmer everywhere, disease infected insects start to move upwards, or migrate, to the north. These bugs will cause some diseases and plagues to spread. Other factors like heat waves and strokes, smog, heart attacks, mold and ragweed that lead to allergies and asthma, and the spread of other various diseases are caused by global warming and can make humans die.

I believe people really should try in some way to help out in the environment. Sure many stores are offering those cloth-like reusable bags for people to buy, but it's up to the shoppers to actually follow through and actually use them in place of the plastic bags. Before doing this blog, I never knew that global warming posed this big of a threat to humans. I knew that it really affected the environment and if we don't stop it, we'll die because of the way it's affecting the environment. But then again, everyone learns something new everyday. But we, as a whole, have to do something to prevent further global warming because if saving the environment isn't a good enough reason, then saving yourself should be.

Week Post One: Causes

A lot of the temperature increase that has been observed is caused from greenhouse gases. These greenhouse gases are water vapour, carbon dioxide, methane and ozone and others. Methane is from landfills and agriculture, nitrous oxide from fertilizers, gases that are used in the process of refrigeration and industrial use. But the main reason is the burning of fossil fuels, which leads to the emission of carbon dioxide. People contribute to the emission of these fossil fuels by driving cars, operating factories, and the production of electricity. Not only is global warming caused from an abundance of gases, but it also comes from the lack of trees. Trees store carbon dioxide, and now that it is the biggest contributor to global warming, so it would be nice if people would plant more and use less of them. Not only do trees store carbon dioxide, but oceans do too, and it holds about 50 times as much as the atmosphere! But because the carbon level is increasing and increasing, the oceans may run out of room to store these things, which will lead to more carbon in the air.

I’ve always wanted to help reduce global warming but it never really worked out because I thought I wouldn’t make a difference. But if everyone thinks that, then the people who don’t think they’ll make a difference will outweigh the amount of people who are trying to make a difference. So as of now, I’ll try my hardest to avoid wasting little things like paper and in the summer, I’ll ride my bike as much as possible to reduce fossil fuel emissions.
