WATER POLLUTION
I think that water pollution is the worst environmental issue we are facing in these days. Many countries are suffering because of this. Only three percent of all water in earth is drinkable and most of it is frozen. Now imagine how much time we have left until we pollute that three small percent that we have left. If we keep throwing wastes to the rivers and the ocean, we are going to reach a time were there is going to be no drinkable water at all. We must be smart with this problem and try to maintain it stable.
Water gets polluted when large amounts of material are added in the water. This happens very often in our planet. There are many causes of water pollution. Some of the types are toxic wastes and organic substances. However the sources of them are farms, businesses and homes. These are the sources that contaminate the most.Farming contaminates a lot because they use dangerous chemicals that are finally washed away into the waterways. Industrial and power plants throw their waste heat into rivers and streams that are nearby. The problem with this is that thermal pollution can occur, which consists in temperature rising and decrease of oxygen, causing animals to die. Finally, homes contaminate with all the fertilizers, herbicides and pesticides used for lawn that get in waterways.
In conclusion, I think we should start focusing on this problem and make a change fast because if we dont, the next generations are going to suffer because of our fault. Lets face it, everyone wants and should live in a clean planet. We need to stop wasting time on useless things and concentrate on the mortal issues we are having lately.
