Nearly 30 years of research was revealed last week when neurobiologist Sam Ridgway went public with his evidence that a particular beluga whale had learned to make himself speak like a human. The revelation has caught the scientific community by surprise.
Disney has become the latest company to vow to eliminate non-sustainable paper products from its operations, wherever possible. That includes in its book publishing, an area where up until two years ago all of the publishers used virgin paper, often coming from rain forests.
In Kenya's Rift Valley, Lake Naivasha drives the economy. It's a draw for wildlife, tourists, business -- and pollution, which is imperiling all the rest. But a series of partnerships have cleaned up the lake and got it back on track.
