Answer Expert Verified True, fresh water is used principally as drinking water. This is because it has low salt concentrations unlike sea water. Fresh water has many benefits to the body and during survival mode this is the only source that can help you get through the challenge.

Answer: The use of water is increasing day by day and the amount of freshwater available for the daily use is less than 1%. There is a huge of amount of water present on earth but that cannot be used because of being salty. The use of water is a concern because most of the water is wasted that water is freshwater only.

• The creation of dams and water-diversion systems blocks migration routes for fish and disrupts habitats.
• Water withdrawal for human use shrinks and degrades habitats.
• Runoff from agricultural and urban areas hurts water quality.
• Draining of wetlands for development depletes habitats.

Freshwater is essential for our planet. Freshwater environments include rivers, lakes, wetlands, streams and underground aquifers. They store and clean the water that’s crucial for people and wildlife. Healthy freshwater environments supply water for drinking, growing crops, manufacturing, energy and transport.

Microscopic impurities like bacteria, viruses and parasites that contaminate water cannot be smelled, tasted or even seen. Hence even if your water is clear, it doesn’t mean it is safe to drink. The unsafe quality of water can cause intestinal infections, typhoid fever, dysentery, hepatitis and cholera.

Since the U.S. Food and Drug Administration (FDA) does not require a shelf life for bottled water, the actual shelf life of water is indefinite! You will probably not find any sell by, use by or best by dates on your bottle of water.

The safest plastic containers to hold water are polyethylene-based plastics, or plastics #1, #2, and #4. All food-grade plastics are made of High-density polyethylene (HDPE) #2.

The U.S. Food and Drug Administration (FDA), which regulates the bottled water industry, does not require a shelf life for bottled water. Bottled water can be used indefinitely if stored properly, but we recommend no more than two years for non-carbonated water, and one year for sparkling water.

The water left overnight or for a long period of time in an open glass or container is home to numerous bacterias and is not safe for drinking. You never know how much dust, debris, and other small microscopic particles might have passed into that glass. Water left in a bottle for a long time is not safe to drink.

Chemical Breakdown Substances in the bottles will leach out into the water, especially if you leave the water-filled bottles in the sun. Plastic bottles made from PET will leach very small amounts of antimony, a heavy metal, in amounts below the World Health Organization’s level for safe drinking water.

Why is bottled water bad for you? Bottled water is laced with harmful chemicals such as phthalates which have been linked to an increased risk of cancer. Additionally, plastic bottles contain BPA which has been linked to various reproductive issues.
