    New Delhi (Sputnik): There have been times when natural disasters like tsunamis, cyclones, and storms ravaged the earth, especially coastal regions. In times like these, mangroves along the coastline are known for minimising damage. The earth, however, may soon be deprived of this natural defence as the cover is rapidly being depleted.

    A video from Dutch research institute Deltares is making the rounds on Twitter. It showcases a model displaying how mangroves act as a natural defence against waves and how mangrove shelter belts are protectors of coastlines during tsunamis, cyclones, and storms by reducing wave and wind velocity.

    ​Mangroves, shrubs or small trees that grow in coastal saline water, are salt tolerant and play a vital role in flood control, soil erosion, carbon shortage, and biodiversity. They have a complex salt filtration and root system to cope with waves and being immersed in salt water.

    According to the World Wildlife Fund, more than 35 percent of the world’s wildlife cover has already been depleted, with Asia the hub for mangrove loss. The figure is as high as 50 percent in countries like India, Vietnam, and the Philippines.

    Important not not just for their resistance to climatic disasters, mangroves provide habitats to various species and are a vital support for the livelihood of coastal communities.
