costal environments - Coggle Diagram

- - - - Local people can fish in coral reefs both for themselves and for commercial fishing (to be sold) providing food and jobs.
    - - Algae and sponges are used in medicines. Some species are being researched for possible cancer treatments, and corals are also used for bone grafts.
    - - Coral Reefs help to reduce the power of waves which would have hit the coastline.
    - - Coral is a vital source of lime used in LEDCs as a basic building material.
    - - Coral Reefs are home to over 25% of all known marine fish
    - - People come from all over the world to reef areas, bringing much needed money for LEDCs to boost their GNP
  - - - tourist can damage the corals by ripping them apart or by introducing toxic chemicals to the ecosystem like sun cream
    - - The introsuction of invasive or non native species damages the coral as some of them might eat the coral or leave them without nutrients
    - - The abundance of fishing done in this areas can leave corals without some species they depend on.
    - - the increase in temperatures leaves some places where coral can't live
    - - the introduction of gases like CO2 give a lower Ph to the water. This results on the limestone the coral is set to be dissolved eventually killing the coral
- - - - mangroves remove a lot of the CO2 present in sea water and store it in the dirt
    - - they stabilize the coastline and reduce the power of storm surges and waves
  - - - deforestation of mangrove forests are very common as mangrove forest are removed to create tourist atractions, residencies and others
    - - plastics or other chemicals cover the roots of the mangroves making it harder for them to survive
    - - the increase of the water temperature is bad for mangroves as the yneed a specific temperature of the water to live
- - - - fore dune: As the sand continues to be deposited on the dune the dune starts to grow and some plants like marram grass start to colonise the dune making the dune more stable, the long roots of the plant stabilise the dune
        
        yellow dune:The process of deposition of sand will continue until the dune reaches 10 m where the dune will stop growing. There are more plants getting to the dune now as it is further from the sea
        
        Gray dune: The plants in the dune start to die off leaving behind hummus which is organic matter. This residue gives a gray colour to the dune and make it more stable
- - - - The slit and mud is continuously deposited making the mudland higher and more resistent
        
        4.
        the non higher mudland now allows less tolerant plants to grow on iy
