This video show the water
pollution, the causes and the consequences
of that.
Water pollution
affects plants and organisms living in these bodies of water. In almost all
cases the effect is damaging not only to individual species and populations,
but also to the natural biological
We all need clean water. People need
it to grow crops and to operate factories, and for drinking and recreation. Fish and wildlife
depend on it to survive.
Some
consequences of the water pollution is that the species that live inside the
rivers will be die because the water it’s dominate. The trees need water to
feed, if the trees don’t feed the humans
can’t because the trees didn’t produce
oxygen.

Many different
pollutants can harm our rivers, streams, lakes and oceans. The three most
common are soil, nutrients and bacteria. Rain washes soil into streams and
rivers. The soil can kill tiny animals and fish eggs. It can clog the gills of
fish and block light so plants die. Nutrients, often from fertilizers, cause
problems in lakes, ponds and reservoirs. Nitrogen and phosphorus make algae
grow and can turn water green. Bacteria, often from sewage spills, can pollute
fresh or salt water.

Toxic Substance
-- A toxic substance is a chemical pollutant that is not a naturally occurring
substance in aquatic ecosystems. The greatest contributors to toxic pollution
are herbicides, pesticides and industrial compounds.
