Water Supply and Demand

By: Audrey Wolz and Max Mueller

Today, water supply and demand is a big issue because only about 2.5% of the Earth is fresh water, and we have about 7.125 billion people living on the planet. We need to either learn how to save and conserve the little water supply we have, or find another way to clean water that we aren't using. Either way, we have to do something, and quick.

Drinking Saltwater?

What? Drinking salt water? If we could invent a new way to clean salt water, this could solve our depreciating water supply.  The ocean covers 71% of the Earth. Less than 1% of Earth's water is fresh water. If we could find a way to make salt water into fresh water then we wouldn't have places running out of water.

What are we doing to try this?

*We are trying to start plants that will clean saltwater, but the Carlsbad plant, for instance, is costing $1 billion to build.

*We are also trying to make a new solar-powered invention by a British company, Desolenator that can turn seawater into drinking water.

*There are also some regions that think that we could do this using just the sun and wind to clean saltwater, this would require the sun and a lot of mirrors that would make the water boil, to get rid of the salt in the water.

Severe drought in the U.S.

Places like California and Texas are in a very bad drought as of now, and since we haven't found a way to make more water, making saltwater drinkable is our best option. The places that are in a drought are doing everything to try and make use of the water that they have, but that may soon not be enough. Since the places that are in need of more water both have a very hot and dry climate already, it make their situation worse. California has many wildfires, and Texas has very hot temperatures so we need to find a solution to their drought, and fast.

California and Texas aren't the only place that can have drought, it is capable of being anywhere that needs water.

What is the drought affecting?

The main thing that drought is affecting is agriculture and farming in some areas that need water and rain for crops and farming. The areas around the world that are known for their crops rely on rain water to provide and water important crops that are used for food and/or trade.

The affect of drought on crops such as corn.

Vocabulary Words

  1. The water cycle- the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
  2. Biome- A group of ecosystems that have the same climate and similar dominate communities.
  3. Evaporation- When a liquid changes to gas.
  4. Limiting nutrient- When an ecosystem is limited by a single nutrient that's has scarce cycles or cycles very slowly.
  5. Climate- The average year to year conditions of temperature and precipitation of a particular region.
  6. Abiotic factors- Physical, nonliving factors that shape the ecosystems.
  7. Recourse- Any necessity to life.
  8. Agriculture- Practice of farming.
  9. Renewable recourses- Resources that can regenerate.
  10. Nonrenewable resources- Resources that cannot be replenished by natural processes.

Three Concepts

Nonrenewable recourses- People need to know that the Earth is running out of fresh water and we can't supply the growing population of the world. Water isn't something that you can just make up, it's nonrenewable.

Climate- The climate of the U.S. is what's causing the drought in certain places and making them run out of water.

Agriculture- The drought around the world is causing a decrease in agriculture which is affecting our food supply and world trade.
