What is pollution? Presence of a waste or an agent. Going beyond the fact that nature can handle it.
Some kinds of wastes, which toxicity levels are very low, but they are considered to be pollutants. Like in a forest, there is little or no organic solvent, a very small amount of organic solvent can be a pollutant since the ecosystem may note handle it.
Oils spills, is another examples.
Types of pollution
§ Point source: oil spill, because you can track the particular point or place.
§ Non-point source: red tide, it is pretty much everywhere. On the air, water, and soil.
