Many of us learn about coral reefs through photos, videos or movies. Others were able to swim in it. In either case, They evoke feelings or images of spectacular environments between rock formations, which contain colorful fish and other creatures of incredible shapes. But they are not exactly rocks.His training is not accidental Its environmental services are decisive for the operation of the ocean and the earth, Not just a part of humanity.
Hard reefs or coral reefs are actually symbiotic communities; that is, Different creatures living together provide advantages for each other to survive. It’s about the relationship between microalgae and zooxanthellae that live in invertebrate Polyps. They require a strong structure to support and protect themselves. Microalgae can absorb nutrients and wastes through photosynthesis.2, The polyp absorbs it and converts it into calcium carbonate (using it to build its hard outer structure). Multiply that by millions of zooxanthellae-polyps, and you will get tall solid structures of various shapes covering a large area of the ocean.
Corals live in warm areas, the seawater is transparent, and the nutrients in the seawater are low in nitrogen and dissolved phosphorus; then, The circulating water stream carries low concentrations of nutrients. These nutrients combine with the hard structures and slow down, so that microalgae can use the nutrients to feed the polyps.It’s a beautiful sight. It grows and the coral reef follows it. It’s like creating an oasis in the middle of a barren ocean. This structure allows other species to grow in it, creating their own habitats. They are some of the most diverse habitats in the world. These are why they are called large biological environment.Its importance
Under normal conditions, corals live in areas where the average annual temperature is between 23 and 35 ºC. Clusters of corals will be formed by these structures, which can produce other species such as fish, sharks and turtles. These environments provide refuge, breeding, and breeding areas for the species that use them in their lives. Then they migrate to other parts to complete their life cycle.They become high-yielding areas and are home to many different species depending on the year and the time of the year.
The Great Barrier Reef in northern Australia is home to the world’s largest coral colony, measuring approximately 2,300 kilometers in length. The Central American Coral Reef System is second, and it runs approximately 1,000 km through the Caribbean Sea between Mexico and Guatemala. These productive and diverse structures serve as natural barriers that protect the coast from winds and waves caused ocean storms.They are also important places for tourist activities because they provide the best sun and beach locations for leisure and recreation.
Due to their characteristics, they are very sensitive and complex systems. Because the sediment contributes to their mortality, the zooxanthellae in the polyps will die. They are blinded and unable to see light for photosynthesis. Pollutants such as grease and oil on the motorboat used by tourists will kill them, and even the oil and fragrance of certain sunscreens will damage themTherefore, if you go to Cancun, if you want to swim in the coral, they will ask you not to use sunscreen.
These tourist attractions emit high levels of nitrogen, phosphorus and sewage. These elements and excessive nutrients will encourage competitive coral species (such a sponge or algae) to settle upon them and eliminate them. The hard structure is then made to disappear. Sargassum, an algae that grows along the Caribbean Sea’s coast, covers the water surface and then degrades to make toxic or harmful organic acids..

Climate change will also affect them. The intensity of the storms is on the rise. They become more susceptible to hurricane-related damage as they approach hurricane season. They cannot recover year after yearIn addition, thawing causes the average sea level to rise, placing them in deeper positions; therefore, the quality of light reaching them is lower, and the resulting erosion covers them with sediments. They will be affected by all of these factors.
Another aspect to consider is ocean acidification associated with climate change.company2 It enters the atmosphere by burning fossil fuels and then into the ocean; there, it reacts with water and forms carbonic acid, thereby affecting these structures. It will not dissolve them instantly, but it will reduce their hardness just like other animals with hard parts made from calcium carbonate.This means that the majority of ecosystem’s biological communities have been affected.
With this in mind, Whitening Coral reef. It does not mean they are doing a good job cleaning up after themselves. All of these factors can make your polyps or zooxanthellae sick, stressed, unable recover, or even kill them. This can cause the structure to lose its color and intensity. It is estimated that between 40% and 60% of its global coverage is lost..
Impact on society
If the ecological role of coral reefs does not seem to be important to you at this time, please consider the disappearing fish with important commercial value. It is dependent on this ecosystem for a large part of its life cycle. The ecosystem is essential for human food production. Without it, the livelihoods of many fishermen families and their economy will be negatively affected. 30% of our country’s total economic output is accounted for by the tourism industry. All indirect effects must be added to this. The impact of hydrometeorological phenomena (storms, floods, coastal erosion) on coastal areas will be like this, for example, everything that is now operating on the Mayan Riviera may disappear.
It sounds quite dramatic, but it is true. It is possible to make it a reality through a series actions that humans directly or indirectly take.Some people are more powerful than others because they don’t know it; others because, although they know it, they ignore it; similarly, there are also people who think that the problem is not theirs and will not affect them, or other people will To solve it. despite this, We all live on the same planet, now is the time for us to act responsibly together. This is something I encourage you to contemplate.
