Water is one of our most precious resources, and is fundamental to life on Earth. Today, consumption of water has increased to the point that water is no longer necessarily a renewable resource. The number one consumer of water in the modern world is in agriculture. Agricultural water usage accounts for 67% of the total water usage by humans. Water use in households for cooking, cleaning, and operating bathrooms only accounts for 9% of water usage. with growth in the population and growing development around the globe, there will be more farming and more domestic water usage. The only way to meet the incredible demand ahead is to develop more efficient water usage systems. We may need to focus on crops that need less water, and to rework the quantity of water used in showers and toilets. Industrial use accounts for 13% of the total water usage, and is made up by manufacturing, power, and mining operations. These industries may also require a rework. The key to meeting the demand of the future and maintaining a level of sustainability is greater efficiency. Where efficiency is not enough, we may have to cut back on water depleting activities.
