Protecting undersea beauty

China Daily  

Majestic coral reef is one of the images taken by Xu Yitang. CHINA DAILY As Xu gained knowledge about coral, including how to regulate factors like water temperature, pH levels and trace element concentrations during the cultivation process, his coral gradually started to flourish. As he delved deeper into the creature, he learned that coral reefs are known as "tropical rainforests" and "underwater gardens "of the ocean, providing a home for a quarter of all marine life. A coral reef's beautiful colors come from the symbiotic algae zooxanthellae that provide more than 90 percent of the energy through photosynthesis. "The clusters of dead coral covered with algae look just like a forest after a big fire, and all is ruin," he says.
