One-quarter of humanity faces a looming water crisis, including the prospect of running out of water, which may seem inconceivable when 70 per cent of the Earth’s surface is water. Nevertheless up to 80 per cent of available surface and groundwater is being used every year and water demand globally is projected to increase by 55 per cent by 2050. Why is the world facing a crisis of water scarcity and what is driving the increasing demand for water?
Explanation:
The first reason that is causing water stress around the world is the growing human population at the same time as the water supply has remained the same. Given that there are almost one billion more inhabitants on Earth every 15-20 years, this has led to a progressive deficit in the global water supply.
The sediments that is composed of mineral grains that are
eroded from the continental rocks is called terrigenous. The terrigenous
sediments are obtained from the erosion of rocks that occurs on land and that
they are being stored in the submarine canyons.
