Importance of water
Water is a vital natural resource essential for all life
forms on Earth. It is used for various purposes, including
drinking, agriculture, industry, and recreation. However,
water resources are finite, and their availability can be
threatened by pollution, overuse, and climate change.
Sustainable management and conservation of water
resources are crucial to ensure a stable and secure
water supply for current and future generations.

the planet's surface
covered by it.
Understanding Earth's Water Resources
Out of this vast water resource, only 3% is
freshwater that can be used by humans.
Freshwater sources primarily include
surface runoff and groundwater, which
are part of the Earth's hydrological cycle.
The hydrological cycle is a continuous
natural process involving the evaporation
of water from various water bodies, cloud
formation, precipitation, and water
returning to these bodies, ensuring its
renewability.
