Write any two causes of water pollution.
Answers
Explanation:
Industrial waste
sewage
oil leakage
There are many causes of water pollution, some of them are:
1- Sewage or wastewater:
The waste from households, factories, or agricultural land gets discharged into rivers or lakes. This waste can either be in the form of liquid waste, garbage, or sewage. The harmful chemicals oozing out of this waste can damage aquatic life.
2- Dumping:
Most water bodies get converted into dumping grounds by nearby localities. And this causes a huge problem because the dump contains everything from plastic, aluminum to glass, Styrofoam, etc. And since all the waste takes different time to degrade in the water, they tend to harm the aquatic life until degraded.
3- Oil pollution:
One of the worst types of water pollution is oil pollution. This is because the oil spills from tankers and ships tend to create a thick layer above the water in seas or oceans. And since oil doesn’t dissolve, the sludge stays forever.
4- Acid rain:
Even though acid rain may seem like a natural problem but it is wise to note that Acid rains are caused due to acidic particles in the contaminated air. These particles in the atmosphere get mixed with water vapor and result in acid rains.
5- Industrial waste:
Industrial waste is filled with lead, asbestos, petrochemicals, and even mercury. All of these chemicals are highly hazardous for both humans and aquatic life. But, many industries tend to discharge the waste into major water bodies like rivers and lakes around living localities, thus, contaminating the fresh water.
