What is coral bleaching caused by?

The leading cause of coral bleaching is climate change. A warming planet means a warming ocean, and a change in water temperature—as little as 2 degrees Fahrenheit—can cause coral to drive out algae. Coral may bleach for other reasons, like extremely low tides, pollution, or too much sunlight.

How can we protect starfish?

One easy alternative method of preserving the starfish is to lay it out flat on a plate and cover it with a generous sprinkling of natural sea salt. Top it with a plate to keep the arms straight. The salt crusting can work to suck any moisture out of the starfish and dry it out, preserving it quite nicely.

Injecting the starfish with vinegar or bile salts is an effective means of killing these coral killers.

How can the crown-of-thorns starfish be controlled?

Ten Simple Things You Can Do To Protect Coral Reefs

1. Conserve water – the less water you use, the less runoff and wastewater will pollute our oceans.
2. Use only ecological or organic fertilizers in your gardens and on your lawns.
3. Plant a Tree – you will reduce runoff into the oceans.
4. Organize a beach clean-up.
