Question

All water found on earth cannot be used for drinking why ?( give reason)​

Answer 1

Step-by-step explanation:

Because much of the water on Earth is polluted or otherwise unfit for human consumption, not all of it can be utilized for drinking. The following are some of the reasons why water may not be safe to drink:

1. Pollution: Many bodies of water, such as lakes and rivers, are contaminated by industrial and agricultural waste, sewage, and other hazardous substances. This can render water dangerous to drink and damage aquatic life.

2. Microorganisms: Many bodies of water contain hazardous microorganisms such as bacteria, viruses, and parasites that, if consumed, can cause sickness.

3. Salinity: Some bodies of water, such as the ocean, contain excessive amounts of salt and other minerals, making them dangerous to drink.

4. Chemical contamination: Groundwater can be contaminated by chemicals such as pesticides, heavy metals and other pollutants that can leach into the water supply.

5. Temperature: Some bodies of water are too hot or too cold to be used for drinking.

Water must be treated before it can be consumed safely. Treatment methods include filtration, disinfection, and removal of dissolved minerals. Therefore, not all water found on Earth is safe to drink, and it must be treated before it can be consumed.

Answer 2

WATER

All water found on Earth cannot be used for drinking because it is not always safe or clean. Water can be contaminated with pollutants, bacteria, and other contaminants that can make it unsafe for drinking. Additionally, some water sources may contain high levels of minerals, salts, and other substances that can make it unpalatable or even dangerous to consume. In order to make water safe for drinking, it must be treated and filtered to remove any contaminants or impurities.
