Water pollution
Water covers over 70% of the Earth’s surface and is a very important resource for people and the environment. Water pollution affects drinking water, rivers, lakes and oceans all over the world. This consequently harms human health and the natural environment.
Causes of water pollution
- Industrial waste: Industry is a huge source of water pollution, it produces pollutants that are extremely harmful to people and the environment
- Radioactive waste: Nuclear waste is produced from industrial, medical and scientific processes that use radioactive material. Nuclear waste can have detrimental effects on marine habitats.
- Oil pollution: Oceans are polluted by oil on a daily basis from oil spills, routine shipping, run-offs and dumping.
Consequences
- Danger in health: Virtually all types of water pollution are harmful to the health of humans and animals. Water pollution may not damage our health immediately but can be harmful after long term exposure.
- Danger in economy: Water pollution can be damaging to the economy as it can be expensive to treat and prevent contamination. Waste that does not break down quickly accumulates in the Earth’s waters and eventually makes its way to the oceans.
- Danger in environment: There are many different types of water pollution and all have a different adverse effect on the environment. For example
• Heavy metals from industrial processes
• Industrial waste
• Microbial pollutants
