Importance of Rainwater

Rainwater is a necessary part of the water cycle on planet Earth and vital to a balanced ecosystem. Rain falling from the sky allows water to reenter lakes, rivers and oceans after being cycled via evaporation. Rainwater is harvested for use on gardens and provides drinking water for humans and other animals.
  1. Water Cycle

    • Rainwater is an important part of how water cycles itself on Earth. Water from oceans travels around and is evaporated into the atmosphere. After enough water is stored in the sky, it eventually comes back down to Earth as rain, feeding plants, animals and people.

    Fresh Water

    • Rainwater provides an environment with fresh water. Rain is necessary to keep water moving around, replenishing lakes, rivers and oceans and moving nutrients along via runoff. Rain becomes part of groundwater that keeps ecosystems in check.

    Water Conservation

    • According to the United Nations Environment Programme, many countries suffering from water shortage benefit from rainwater harvesting projects. Rainwater is harvested to provide people with water for drinking and agricultural uses.
