Help preserve our marine life forms
Within a month's time, i have been travelling to Tioman twice. The first time was to help a friend in her Master's research and the other time, was to carry out reef check. The last dive i did was in February. Surprisingly, within approx 5 mth's time, everything in Tioman had changed. The corals are seriously in stress due to the heavy construction along the beach. For the first time in my life, I'd seen serious bleaching of corals in depth less than 2m. To some people, this is just normal. But as for a diver, and as a person interested in corals research, i find that this phenomena is a sign that the environment is seriously changing.
Bleaching, is an event where the zooxanthellae inside corals are expelled and the corals starting to loose their natural colours turning white, just like the two pics shown top right and left (i try to briefly explain in the layman's language). Bleaching in Tioman has gone serious, with even the most robust of them all are also bleached. The only factor that may be involved or in relation with bleaching event is water temperature. The water temp for last few months have been increasing based on recorded data from a reliable source. No many people know that although with an increase of 1 degree of celsius, is already providing stress to the corals. Corals can actually be the indicator to the changes in the environment as they are very sensitive to slight changes. They are also very fragile. Some corals, would only grow bout 2 cm a year (imagine now how long a big coral have been living).
One big problem to corals in Malaysia is that not many issues and phenomena have been recorded or documented. Even that, the development that have been taking place, will always 'forget' the importance of marine life forms. For bleaching event, as far as we know, the last event was in 1998. Therefore, i hope that snorkellers, and leisure divers, would report to the authorities of any bleaching event (either Marine Parks, or any universities in Malaysia, UM, UKM, UMT or UMS). This small report would help to enhance the conservation movement around Malaysia. We can see improvements (just improvement, but still more to do) however but unfortunately, these were focused on terrestrial organisms. Many are not aware of the marine ecosystem is equally important or i would say play more important role than the terrestrial ecosystem.
Development are important, but think again, without the natural resources, will there be development? Isn't it time for all human being (especially business minded people - and i do really mean it) to stop being selfish and try to save the world. Some will go "oh my gosh, that's horrible!" and then do nothing. Small contribution is better than no contribution at all. Development will create heavy sedimentation to the seawater (refer pic on the right, the view is being blocked by sediments), and that will reduce the light received by corals. Even small particles can reflect light, what more sediments. What's the point of development, when they will destroy the environment? Its a fact that the world doesn't belong to us, but to the future generations. What we do today, may be harmful for our children. Stop being selfish, some would even think what's more important to them now, rather than the future.
Let us all pray that the corals that are facing this massive bleaching event, will be able to recover. Another information to share is that although bleaching is a catastrophe, but they are not dead yet. Corals have the ability to recover when the water temp begin to cool, where the zooxanthellae will be able to get back into the corals. This recovery event is like chasing the time. If corals are bleached for too long, they will eventually die, or when algae grows faster than the recovery rate, that's the end for the corals.
