Coastal zones occupy less than 15% of the Earth's land area, while they host more than 40% of the world population.

Almost two billion people do not currently have access to clean drinking water. [38] [39] A study in 2016 calculated that the number of people suffering from water scarcity increased from 0.24 billion or 14% of global population in the 1900s to 3.8 billion (58%) in the 2000s. [1] This study used two concepts to analyse water scarcity.

They are the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere. [28]: 1451 Earth's climate system is a complex system with five interacting components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).
