Three of the worlds leading problems are Global Warming , Ozone destruction and War.
As you can see that all three co-relate to the environment that we have. A main point for each would be that war can contain nuclear arms destroying pretty much anything in its path, and global warming and ozone destruction will have us end up drowning in water or boiled by pure sunlight.
The first topic on my mind is global warming. I know, I know most people think that its not real, or that's it's just a hot phase like the ice age. I hate to be the bearer of bad news, but it is true. If we don't try to fix it soon the earth will be destroyed in a way that we will never be able to get it back. With the polar ice caps melting from concentrated sunlight the oceans will rise and most cities that are near sea level will be flooded like Bangladesh. Some small islands may go under like “Atlantis”.
The hole in the ozone layer is a huge problem since O3 (3 oxygen molecules make up ozone) is destroyed by CFC's (Chlorofluorocarbons) which are simply all aerosols such as body sprays, spray paint, and some types of whipped cream, etc. Without an Ozone layer our bodies will “bake” in the sun since the ozone protects from dangerous UVB rays which are known to cause skin diseases such as melanoma and we are hit by radiation directly from the sun.
War is the third problem. Not enough people care about the problems of war. Every time you see a tank being blown up do you think people come in and remove the shrapnel that will probably end up leaking some types of metal into water polluting it. As well the metal that stays there is a danger to anyone who comes by since it might be radioactive. An atomic bomb takes the cake for all destruction of environment since the one that was dropped on Hiroshima and there still is radiation leaking from that area in Japan.
Some ways we can help the environment is anti-war protests, CFC protests and other types of protests. What you can do in your own houses is save resources such as energy conscious products, gas saving methods of transportation and using alternate items such as a concentrated juice and adding water instead of a pack of juice boxes.
In conclusion the following methods are all useful in trying to be environment conscious. Even if you are not a kind of person who would protest about every single thing they see they will still be able to work on helping the environment.
