Pollutants are things that make the environment unclean. Pollutants can be in the air, water, soil, or anywhere else, even in the body. They can be caused from sound, light, trash, chemicals, exhaust, and many other things. When pollutants cause the air, water, or ground to go bad, many things are affected like our food and water and even the air that we breathe into our bodies. This causes a myriad of physical ailments like cancer, brain damage, and respiratory illness. It can also be a huge problem for plants, causing them to be toxic or to quit growing all together. When plants fail to grow in areas like the rain forests, the whole ecological system doesn't do right. Then, the animals are affected too.
Animals drink polluted water, eat polluted food, and breathe polluted air just as humans do and this causes a world of problems, especially the animals that humans eat. Pollution is a cycle that is damaging and dangerous. But, efforts are being made to correct it all and you can help. Each individual who helps is apt to make a difference.
Pollutants are substances that spoil what is good in our environment. If you poured yourself a cup of coffee and someone put dirty washing up water into it, the coffee would be polluted. In the same way what we put in our rivers, seas, air and land can and often does pollute it. For instance, waste matter like used cans in land, or plastic bags in the sea.
