Despite the search for the exoplanet continued unabated, there are no evidences of finding an alternate to the planet earth in the entire universe so far, as the Earth has got several distinct features suitable for the survival of plants, animals and microbes. The biodiversity present on the earth is massive that it is not an exaggeration to state that there is no second home for the human and the other living organism.
The hectic human activity is creating chaos and the debate on the climate change came to the fore front for the first time on a massive scale during the ‘Earth Summit’ in the year 1992 at the Brazilian city Rio De Janeiero. Ever since that time the debate on the undue changes on the Earth’s climate due to anthropogenic activity is on and the awareness is spreading gradually. Yet, the catastrophe did not stop. The panoramic and rare forms of life in the marine waters started vanishing to the extent that the damage is irrecoverable. For quite some time, the scientists and the environmental researchers are warning about the coral bleaching. Corals reef ecosystem is so diversified that they are home for Zooxanthellae, algae and seagrasses. These plants provide food and oxygen to the animals that live on the reef. Seagrasses is the habitat for juvenile reef animals like conch and lobster. As a result of rising marine water temperature, coral reeves are completely bleached threatening the very existence of the marine life. The Great Barrier Reef of Australia for example is worst affected, causing massive revenue and employment loss. The Great Barrier Reeves have withstood the erosion and climate changes over the decades. Yet, the current happenings are so dramatic and long lasting, which are irreparable. This would for sure is going to threaten the future of the iconic ecosystems and the livelihoods of many millions of people.
