How Coral Reefs Are Affected
Coral reefs biggest threat is rising temperatures of ocean water. As the temperature of water rises, corals lose their symbiotic partners, the algae providing the corals with food. This leaves corals "bleached", which is when the corals lose their bright colors. If this condition continues parts of the reef may start to die off, and the whole colony or reef may die. To help prevent coral bleaching, people can walk to work or school or bike or carpool, because the less we burn fossil fuels, the less global warming is worsened.
