Baby steps to conserving the marine ecosystem

There are so many fun water activities to do in the summer, such as swimming at the beach, junk trips, snorkeling and scuba diving. While you’re having fun, however, don’t forget to be aware of how you may be affecting the marine ecosystem!

Hong Kong has rich coral areas and is said to have more species of coral than even the Caribbean Sea. Coral is very fragile, however, and even coming into contact with the slightest pollution can have serious consequences. In recent years, a number of factors have led to coral bleaching. These possible causes include: climate change, a decline in water quality, and surprisingly, the use of sunscreen!

Actually, there are some things we can do to help protect the coral. In addition to disposing of rubbish properly, we can also pay attention to the sunscreen products we’re using when taking part in coastal or water activities. Overseas studies have concluded that the chemical components in some sunscreens, such as oxybenzone and benzophenone-2 (BP-2), may cause coral bleaching or serious harm, even at very low concentrations.

Sunscreen tips to help reduce the damage done to coral:

• Choose a physical sunscreen product with titanium oxide or zinc oxide.
• Choose a biodegradable sunscreen.
• Apply sunscreen 30 minutes before entering the water and ensure that it is has been absorbed to reduce the chance of it getting into the water.

Dr. Simon Chau, who has been promoting environmental protection for more than 30 years, briefly explains the impact water activities have on the ocean. He also introduces a natural alternative to manufactured sunscreens; so that when we take part in water activities, we can be protecting our skin and the ocean!
