The popular dive spot is southeast of the Philippine capital, Manila.
BBC Philippine correspondent Howard Johnson joined dive professionals from Anilao Scuba Dive Centre as they resumed diving, following the national lockdown. The dive centre is affiliated to the United Nations Environment Programme’s Green Fins, which promotes sustainable marine tourism in South-East Asia.
A new study conducted at the Norwegian Institute for Air Research suggests wind-borne microplastics are a bigger source of ocean pollution than rivers, the route that has attracted most attention to date.
Airborne transport has received much less attention than rivers because only the smallest particles can be blown by the wind and their size makes them difficult to identify as plastic. The scientists concentrated on fine tyre and brake dust as there is better data on how these are produced than tiny microplastics from other sources, such as plastic bottles and packaging.
To understand sea turtle behavior around ocean plastics, the research team compared how sea turtles in a lab setting reacted to smelling odors of turtle food, ocean-soaked plastic, clean plastic and water.
The turtles ignored the scents of clean plastic and water, but responded to the odors of food and ocean-soaked plastics by showing foraging behavior. This included poking their noses out of the water repeatedly as they tried to smell the food source, and increasing their activity as they searched.
On 10 May 2018 David Jones will be talking on "Marine Plastic Pollution: How did we get here and what can we do about it?"
Plastic pollution is undoubtedly one of the biggest environmental issues we face at the moment. Plastic has only been in our lives for around seventy years, so how did we get to where we are, what went wrong? More importantly, what can we do about it?" David Jones.
Only a fraction of the plastic we produce is recycled. Every year 8 million tonnes of plastic is dumped into our oceans. A fact that most of the world either ignores or is unaware of. Now an adventure documentary will expose the horrible truth behind the plastic we throw away.
