Coral reefs are one of the Earth’s most beautiful, ancient and complex ecosystems. They play an essential role in sustaining life in the sea and serve as a source of food and protection for human communities. But coral reefs face an uncertain future. As a result of growing human and environmental assaults, reefs are among the most threatened ecosystems on earth. Ecological research provides information fundamental to understanding and combating this trend. Corals are actually animals with plants living inside them. A coral structure is actually composed of hundreds or thousands of tiny animals growing together as a colony which make a coral. Several polyps make a coral which together form a reef.
Coral reefs are the most diverse and productive marine communities on the planet. They play a critical role as habitat and nursery grounds for 10 to 20% of the world’s fisheries. They are intimately connected to other marine communities such as mangrove forests, sea grass beds, and the open seas as water currents transport larvae, plants, animals, nutrients, and organic materials. They play a significant role in the development of other ecosystems such as mangroves and wetlands and protect coastlines from wave and storm damage and erosion.

Nature is the most generous supplier of nourishment and guidance to us as humans. We are often advised to be in harmony with nature, and to achieve that, following measures are advised: Get outside; take a nature walk. Read books about nature. Grow more plants. Shut televisions. Submerge in nature; meditate. Pick up litter. Reuse, recycle and reduce. All the above mentioned measures can be categorised under the following three headings except:

Lion habitats are almost extinct in the country. Even keeping this fact in mind, the most sensible strategy would be to desist from re-introducing lions in habitats where they have once been poached to death. Trying to bring lions back to habitats where they are likely to encounter a killer human contact is sinful.

The argument above depends on

Chipko Movement was started in 1970s in a small village of Garhwal high up in the Himalayas. Villagers stood up against greedy contractors. Women folk hugged the trees. The Chipko Movement spread slowly to all nearby areas under the leadership of Shri Sunder Lal Bahuguna.

Why do we need to save trees?
