00:00 Coral bleaching or coral bleaching is a common phenomenon in the world's most famous diving sites.
00:08 It is also a problem for many fish, which is why it is a threat to our food supply.
00:13 Here is our special report.
00:15 Full of color.
00:21 The sea is full of it.
00:23 That is why Tubbataha Reef is one of the most popular diving spots in the world.
00:30 But in this March, the coral in some parts of Tubbataha Reef in Sulu Sea turned white.
00:38 This is called coral bleaching.
00:41 According to an expert of the Tubbataha Management Office,
00:45 the coral turns white because they expelled the algae that gives color and also the necessary nutrients for the coral.
00:53 Corals are known as animals.
00:57 So they depend mostly on producing their food using photosynthesis and through filtration.
01:06 A small change in the temperature of the sea can expel the zoosanthellae.
01:15 When they are stressed, they expel the zoosanthellae until they leave a clear texture that is like fluorescent.
01:25 But coral bleaching is not the only problem in Tubbataha Reef.
01:29 Based on the health analysis of corals in the Regional Marine Protected Area of the Philippine Marine Conservation,
01:36 compared to 2019, 2% of coral bleaching was 16% in 2022.
01:42 95% of healthy coral in June 2019 turned 68% in 2022 due to bleaching and other factors.
01:51 According to Shoal or Escoda Shoal, almost all corals there are dead.
01:56 That's really an ecological disaster.
01:58 In the past, we saw a lot of degradation.
02:01 The West Philippine Sea now is really in a very alarming and severely degraded state.
02:07 The National Oceanic and Atmospheric Administration of America confirmed that the world is experiencing the fourth global bleaching event.
02:16 What is being pushed there is climate change.
02:21 Due to extreme temperature changes, those places near the equator are experiencing more heat from our ocean.
02:34 Like the Philippines, Australia, and some other tropical countries.
02:39 Coral bleaching has a big effect in the Philippines, especially when we are surrounded by water and one of the sources of food is the ocean.
02:48 Corals can be extinct.
02:50 Those fishes and other inverts and other biota that rely on our reefs can disappear in the long run.
02:58 Our food sources can disappear.
03:01 Not totally, but in the long run, in the future generations, maybe there will be no more corals that our grandchildren will see.
03:10 When there is coral bleaching, corals do not die immediately.
03:14 Mostly, during the process, they do not die immediately.
03:19 The corals can return to the corals on Sunday or later to come back to life.
03:24 Although ordinary people can help.
03:28 By doing a simple, throwing the right trash in the right place, it is a big help to help the marine protected areas.
03:42 Thank you.
