Coral reefs and pollution
How is water pollution affecting the coral reefs throughout the world?
It helps some and hurts others. When a big piece of junk like a shipwreck or
an old car sinks to the bottom of a sandy sea, it gives coral a place to
attach and grow. However, changes in water chemistry or temperature can be
fatal to reefs.
You should check you library or bookstore for "The Greenpeace Book of Coral
Reefs" by Sue Wells and Nick Hanna, 1992.
