What can be done to protect water pollution?
I assume the question is "What can be done to PREVENT water pollution?" The three big sources of water pollution are (1) industrial waste (2) agricultural pesticides and fertilizers (3) human careless discarding of all sorts of things. Spilled oil and petroleum products are a major water pollutant. Most underground tanks at gas stations leak. Many cars and trucks leak oil and other fluids. We have improved to some degree in North America and Europe but many people are still careless, even reckless, in their habits. North America and Europe are a small part of the world population. China and India cannot handle their massive populations and are major polluters. Latin American countries are also major polluters. Most African countries are industrially backward or they would be major polluters too.
Why is plant extract green?
Plants are green because of the presence of a green pigment called chrolophyll. This pigment is responsible for sunlight hervesting.

Actually, most plant extracts are not green, and you can see the colors at herbalextractsupplier.com.
