<span>Fresh water is a natural resource while is steadily declining, most prominently in areas such as Asia and North America. There is roughly 326 million trillion gallons of water on this earth however only 3% is drinkable, fresh water. The most significant use of water is to produce hydropower through harnessing its energy, however fresh water is also extracted for consumption, farming and many other daily chores. According to experts, when the annual water supply drops below 1000 m3 per person, this is when the population of that area faces water scarcity. It is predicted that by 2025, most countries within Africa will face this extreme water scarcity as a result of an increasing population and therefore increased water demands. Humans can limit their consumption by conserving fresh water for uses outside of consumption. Water is renewable through rain however we are depleting it at rate in which is cannot be sustained.</span>

It describes how ecosystems, air quality and sustainability of our assets should be studied and protected and focuses on the components that affect the environment
Dams, water treatment plant industries, water tanks etc.

Sandstone is a type of sedimentary rock that is formed by physical weathering of parent rocks. It is usually made up of sand size particles of minerals, rocks, other organic materials and the cementing material that bind the sand grains together.
Sandstone can not be found as a chemical sedimentary rock because it is formed by mean of physical weathering and not by chemical reactions of the rock.
