As Earth’s population continues to grow, people are putting ever increasing  pressure on the planet’s water resources. Water pollution not only affects individual living species but also populations and entire functioning ecosystems that exist in the waters. Oceans, rivers, and other inland waters are being “squeezed” by human activities not so they take up less room, but so their quality is reduced. Poorer water quality means water pollution. The main cause of Water pollution  are factories, industries which release their waste material into water . In this way they pour gallons of waste into a river. It will affect  the water and it will  have an effect on the health of all of the vegetation, animals, and humans whose lives rely upon the river.
