Dead-tree pyramids show promise as quick and easy artificial reefs

Although artificial reefs certainly do help restore damaged marine ecosystems, they’re usually made of heavy manmade materials that must be formed into shape. Now, however, scientists are reporting success using readily-available dead pear trees.Contin… Continue reading Dead-tree pyramids show promise as quick and easy artificial reefs
