Water for Life: Sustainability of Water

Water is one of the most important national resources in the world as it is used for so many things and is irreplaceable in our everyday lives. Water is what keeps humans and plants alive and is also used for energy.

The entire world population depends on it to live and without it there wouldn't be any life. Even though 70% of the Earth’s surface is water, Most of it is made up of salt water and is unhealthy for humans to drink. Our reliance on water has led to the fact that we are constantly using it for the wrong purposes and wasting it.

With the United Nations projecting the world's population would surge to 9.7 billion by 2050, the challenge of water sustainability would be both a political and ethical issue. Water is being wasted a lot more than you think.

People in developing countries experience major lack of water issues and it is becoming an increasingly huge problem. As the Chinese saying goes, “Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.” This means instead of just benefiting from someone else once, we should learn the ability and use it properly.


70% of the Earth’s surface is made up of water. The total volume of water on Earth is about 1.4 billion km3. The volume of freshwater resources is around 35 million km3, or about 2.5 percent of the total volume. Up to 90 % of wastewater in developing countries flows untreated into rivers, lakes and highly productive coastal zones, threatening health, food security and access to safe drinking and bathing water. Every day, 2 million tons of sewage and industrial and agricultural waste are discharged into the world’s water.

Can we Improve?

Many People are already working on making water more accessible for developing countries. Some easy ways you can help is by:

  • Taking shorter showers.
  • Turning the Water off before going on vacation.
  • Saving Dirty Water to water plants.

Water is the most important resource in the world, being used by EVERYONE on the planet. However, it is also the most wasted resource. Water is still very scarce in developing countries and many still die from lack of water. It is not too late for all humans to work together and make water available for everyone.
