The World Health Organization warned that millions of people may face poverty, disease, hunger, and other atrocities due to climate change. The adverse effect is as a result of rising temperatures and changing rainfall and the worst sufferers will be from poor countries
They too started responding to rising CO2 levels according to studies. In areas where waters are rich in dissolved CO2, acidifies water there by making it harder for coral polyps to build their chalky shells. Studies in the eastern Pacific Ocean support this finding. The corals in these stress full condition are more porous than reefs that grow in other areas where water contains less CO2 and are more vulnerable to erosion. High CO2 in sea water hinders reef development and accretion, there by checks the coral species diversity and richness. ‘Science publication of conservation international and the international union for conservation of nature reported one third of the worlds reef building corals are at the risk of extinction. Warmer waters encourage coral bleaching, there by leaving the colonies devoid of life. Health of corals on a global scale shows that they are more sensitive and vulnerable to climate change. In no time we will lose those magnificent under water life forms, which pamper countless other aquatic lives.
