It puts into context the BP Deepwater spill in the Gulf of Mexico, which we also continue to cover - looking at how the ripples are spreading into the tourist and many other industries.
As the International Whaling Commission continued its crucial and controversial meeting, we looked at the efforts by campaigners Sea Shepherd to deal with another threatened species - the bluefin tuna.

Much less charismatic, but perhaps even more under threat is the Cordyceps sinensis fungus - so-called Himalayan Viagra" - that's being harvested with increasing intensity on the Tibetan plateau. Could it go the way of silphium?
But progress is being made, we learn on the science pages, on electric cars - provided you've got plenty of cash. Look out for a car with "E" in its naming coming soon near you.
