in the tropics, coral reefs face a host of interconnected problems (bleaching, corrosion, disease, spreading seaweed, invasive species) that are all caused by rising CO2 levels. the spread of marine life that cause problems, such as toxic jellyfish blooms and rotting algal mats and Based on a synthesis of evidence available to date, there was predicted the problems associated with harmful marine life will get worse in response to rising CO2.

Small creatures can be a good indicators for climate changes. We need to study these creatures and the study must be for a long term and global, Networking and collaboration among scientists in the world is important.
