Water pollution can have many sources. Since water is the basis for all life on earth and utterly essential to our survival as a species, any form of water pollution could have largely detrimental effects on our health. There are many direct and indirect sources of water pollution
These are the main causes of water pollution:
- Industrial and Household Waste
Industries produce large amounts of waste which holds poisonous chemicals and
pollutants. Many commercial enterprises don’t have proper waste management and the waste drains into our clean water, polluting it. Artificially treated sewage and waste water from family homes also contains destructive microscopic organisms which can cause diseases. Land Pollution also affects the water because landfills will leak into our underground water supply, adding more contaminants.
- Dumping into the oceans
The garbage made from non-biodegradable materials such as plastic gets dumped into the oceans and accumulates, causing harm to wildlife. Oil leaking into the oceans causes the same problem. The currents of the oceans will cause these materials to accumulate in patches such as the Great Pacific garbage patch.
- Farming and agriculture practices
The fertilizers, pesticides used by farmers, and animal wastes from large production plants get washed away with the rain and leak into our rivers and waterways.
- Fossil Fuels and Air Pollution
The fossil fuels burned, which cause air pollution, also are a problem because they will go into the atmosphere and then come back down into our water in the form of acid rain.
Why is Water Pollution bad?
Drinking water is becoming a scarce resource, especially in developing countries. Water pollution is responsible for many deaths due to diseases and also causes deaths due to lack of clean drinking water. In addition, the marine wildlife is constantly threatened by all of the dumping practices which accumulate toxic chemicals within our oceans.
