Coral Reefs and Mangroves as a part in our Ecosystem and in our Lives

The Importance of Coral Reefs and Mangroves
Corals and mangroves help a lot not only for our ecosystem but also for us humans. So it is necessary for us to discuss its importance. Let’s have first the coral reefs.
Coral reefs as a sustaining tropical marine ecosystem. Coral reefs maintain a balance life with the mangrove and sea grass ecosystems hear the coastal shores. Second, coral reefs as primary producers. Coral help in reducing the effects of CO2. Coral reefs support the food chain by being a food for tropical fish and other marine animals that serve as a food for animals, higher in the food chain. Third, corals as a coastal protection. Corals can be called as nature’s defense mechanism to prevent coastal soil erosion and flooding. Fourth, coral reefs as a cultural significance. Corals are worshiped as life sustaining organism in innumerable cultures around the world. For Fiji, coral reefs are symbol of life and reverence and sane is true for many other cultures around the world. The other importance of coral reefs is that corals provide shelter, nutrition and habitat to almost a quarter of the world’s fish. Think how valuable is this contribution when it comes to the national, international and local fisheries. Those are some of the reasons why a coral reef is important.
Like coral reefs, mangroves are extremely productive ecosystems that provide numerous goods and services both to the marine environment and people. Mangroves serve as nurseries for many fish species, including coral reef fish. Mangroves as a timber and plant products. Mangrove wood is resistant to rot and insects making it extremely valuable. Many coastal and indigenous communities rely on this wood for construction material as well as for fuel. Mangroves as a coastal protection. The dense root systems of mangrove forests trap sediments flowing down rivers and off the land. This help stabilizes the coastline and prevents erosion from waves and storms.
The importance of coral reefs and mangroves nowadays increasingly highlighted in newspapers and science journals and people are becoming aware of the crucial role they play in our lives. At an individual level, at least we try to make people be aware of the importance of coral reefs and mangroves and must take certain changes.

The Importance of Earth's Hydrosphere


        Earth's Hydrosphere plays a big role not only for us humans but also for our nature and environment.But even if  we already know that we often times take for granted its value or impact to us.So let me discuss to you  why is Earth's Hydrosphere is important .Water is our lifeline  that bathes us and feed us. In ancient culture water represented the very essence of life.Hydrosphere composes of  seas or ocean,lakes,rivers and etc.


               

               Water provides  a habitat  for many animals and for plants to live.Human also use water in a number of ways.Drinking water is obviously very important.Water is also used domestically (eg.washing,cleaning) and industry. The other important  of water  is that water use to regulate the temperature on earth.The earth takes a long time to heat up as well as a long time to cool down and if  water  doesn't exist the earth also would not exist. Water is a living cell.Our body composes of  substances that should dissolve by water therefor without water life would not exist.






              Those are some of  many reasons why  is Earth's Hydrosphere is important.We should  give care to our Earth's Hydrosphere.We should not do things that would destroy our mother earth cause everything  we do in our environment weither it is good or bad  affects as a lot think of it.
