Despite pressing environmental problems such as pollution and the extinction crisis, there are still plenty of reasons to be optimistic, UNEP chief Erik Solheim tells DW.
DW: What would you say are the greatest environmental problems we’re currently facing?
Erik Solheim: One is pollution, and pollution of course is the key also to climate change; if we really fight pollution, we will solve the climate problem. And the other is the decline in so many of the most iconic species, and the beauty of the nature — the elephants and the rhinos, and of course a huge number of animals here in Germany.
