Water Pollution.

Hello everybody I do want to talk about water pollution.
Talk about environmental problems is talk about water pollution that is another problem in our country; there are many causes for water pollution but two categories exist: direct and indirect contamination sources. Direct sources include effluent outfalls from factories, waste treatment plants etc., which emit fluids if varying quality directly into urban water supplies. Although these practices are regulated, this doesn't mean that pollutants can't be found in these waters. Indirect sources include contaminants that enter the water supply from soils/groundwater systems and from the atmosphere via rainwater. Soils and groundwater contain the residue of human agricultural practices (fertilizers, pesticides, etc.) and improperly disposed of industrial wastes. The effects of water pollution are varied and can be severe. They include poisonous drinking water, poisonous food animals, unbalanced river and lake ecosystems that can no longer support full biological diversity, deforestation from acid rain, and many other effects. These effects are harmful to everyone. We must think about the problems that we are going to face in a near future. I recommend you to look for some solutions in order to quit the contamination of our environment It´s time to start just you have to be focus on the future of your kids if we continue polluting the environment kids are going to suffer. Stop now and be happy later
