Pollution is one of the most ignored concepts in the modern world. It is a topic that often gets forgotten by talk of conservation, sustainability, climate change and energy issue, perhaps, because it is a complex subject with lots of sources and lots of effects. In spite of the fact, that pollution is one of the biggest global killers. At the same time, it can be solved in our life time, and the solutions are relatively low-cost. There are some major substances that may cause pollution, such as: Nutrients, Pesticides, Heavy metals, and suspended solids.
