Summary:
An increasing proportion of the world's protected forests are subject to extensive logging activities. The practice is called 'salvage logging' and allegedly aims to protect, e.g. areas of windthrow against bark beetle infestation. However, a new study has found that this instrument is used far too often.

Summary:
When British naturalist Charles Darwin traveled to the Galapagos Islands in 1835, he took notice of the giant kelp forests ringing the islands. He believed that if those forests were destroyed, a significant number of species would be lost. These underwater ecosystems, Darwin believed, could be even more important than forests on land.
