Answer 2

To find: Primary causes of water pollution.

Step-by-step explanation:

• Polluted water is water that has had its composition altered to the point where it is no longer usable. To put it another way, it's poisonous water that can't be drunk or utilized for critical purposes like agriculture, and that causes diseases like diarrhea, cholera, dysentery, typhoid, and poliomyelitis.

The main causes of water pollution include:

1. CO2 emissions cause global temperatures to rise, which heats the water and lowers its oxygen content.
2. Forest thinning has the potential to deplete water supplies and produce organic residue, which can serve as a breeding ground for harmful microbes.
3. More than 80% of the world's sewage is discharged into seas and rivers untreated.
4. Plastic pollution in the water is primarily caused by fishing boats, tankers, and cargo ships.
5. Our water supplies are contaminated by leakage from the transportation and storage of oil and its byproducts.
