If fish disappear, it will disrupt the food chain in water ecosystems. Birds, frogs, snakes and other animals that depend on fish for food will face starvation. This can lead to their extinction too. Humans who rely on fishing for food and livelihood will be affected. Such imbalance weakens the ecosystem, reduces biodiversity and makes the environment unstable for other aquatic life forms as well.

The majority of Earth’s water is in the oceans and is too salty for drinking or farming. Only a small portion is freshwater and much of it is locked in glaciers or deep underground. The available freshwater in rivers, lakes and underground sources is limited. Because desalinating ocean water is costly, we mostly depend on these small freshwater sources for drinking, farming and everyday use.

Living beings settle near water bodies because water is essential for survival. It provides drinking water, supports farming and sustains aquatic plants and animals. Rivers and lakes also offer food like fish and water for animals. People build homes near water for agriculture and daily needs. Plants grow well there due to moisture. Thus, water bodies create a complete environment to support various forms of life.
