FRESH WATER

Most of our planet is covered in water. However, according to the World Meteorological Organization, “only 0.5% of water on Earth is usable and available freshwater.” Although this relatively small amount of fresh water should be enough for life on earth, much of it is either becoming polluted or becoming inaccessible as a result of increased demand and climate change. Experts predict that within 30 years, five billion people could have inadequate access to fresh water.

The earth has natural processes that prevent our water supply from disappearing. Also, soil, aquatic life, and even sunlight cooperate to purify our water. Consider some of the evidence that points to our planet as one that is designed to survive.

• It has been shown that soil can efficiently rid water of many contaminants. In wetlands, certain plants have been known to remove nitrogen, phosphorus, and pesticides.

• Scientists have identified physical and biological processes that purify water contaminated with naturally occurring organic waste. The contaminants are diluted in flowing water and broken down by microorganisms.

• Freshwater clams and mussels can extract some potentially harmful chemicals from water in a matter of days​—and perhaps do so even more effectively than water treatment plants can.

• Our planet keeps water trapped in a constant cycle known as the hydrologic system. This cycle, along with other natural processes, prevents water from escaping our atmosphere or otherwise disappearing.

Experts recommend conserving water whenever possible. To reduce water contamination, they advise repairing any oil leaks in our vehicles and not flushing unused medicines down the toilet or pouring toxins down the drain.

Engineers have come up with impressive methods of modernizing desalination (the removal of salt from salt water). The goal is to increase the amount of accessible fresh water.

But more is needed. Even desalination seems to be unrealistic as a large-scale solution because of its high cost and because it requires excessive amounts of energy. In a 2021 report about water management, a United Nations source stated: “Globally, the current rate of progress needs to be doubled.”

“God . . . draws up the drops of water; they condense into rain from his mist; then the clouds pour it down; they shower down upon mankind.”​—Job 36:26-28.

God created natural cycles to protect earth’s waters.​—Ecclesiastes 1:7.

Consider: If the Creator engineered processes to purify fresh water, might he be able and willing to repair the man-made harm to this vital resource? See the article “God Promises That Our Planet Will Survive,” on page 15.
