Effects of Water Pollution

The effects of water pollution are far-reaching and affect not only the environment, but human beings and animals as well. Water pollution affects our oceans, lakes, rivers, and drinking water, making it a widespread and global concern. Numerous diseases, health problems, and even fatalities have been associated with water pollution.
The food chain is damaged. When toxins are in the water, the toxins travel from the water the animals drink to humans when the animals’ meat is eaten.
Diseases can spread via polluted water. Infectious diseases such as typhoid and cholera can be contracted from drinking contaminated water. The human heart and kidneys can be adversely affected if polluted water is consumed regularly.
Acid rain contains sulfate particles, which can harm fish or plant life in lakes and rivers.
Pollutants in the water will alter the overall chemistry of the water, causing changes in acidity, temperature and conductivity. These factors all have an affect on the marine life.
Marine food sources are contaminated or eliminated by water pollution.
Altered water temperatures (due to human actions) can kill the marine life and affect the delicate ecological balance in bodies of water, especially lakes and rivers.
Water pollution effects have a huge impact on our environment and health. The delicate balance between nature and humans can be protected, but it will take efforts on all fronts to prevent and eliminate water pollution locally and globally.
