I had an underwater explore for my activity. In this service group, I had learned about the global understanding.

Underwater explore is a service group which is to collect some data by measuring the temperature and the depth, also the length. This is all because we need to see and compare the difference of the corals, sea water, temperature changes etc. The purpose of comparing the difference is to protect the underwater environment. If the coral is dying each year, we could notice there might be a bad influence so we could search for the cause. We usually call the dead corals “White Syndrome”.  The causes of the white syndrome are pollution and the global warming. Pollution happens because of the rubbish which people simply throws it away, but also because the licking oil from the ship also affects the pollution too. Secondly, global warming does influence the coral badly is because the ice liquefied by the heat so the mass of the sea water increases. If the seawater increases, the plankton also increases a lot.  If the plankton increased too much, the sunlight will be covered by the plankton so the coral will start to die.

Coral is important for the ocean. Coral absorbs carbon dioxide and discharges oxygen. And the fishes do the opposite thing. coral and fishes help each other so it is important to protect the coral. So for the conclusion, I had learned about this.
