You raised money for World Land Trust what does it do?
It's an organisation that buys chunks of rainforest around the world so that they can be protected- the trees can't be cut down and the animals can't be poached. It seemed like a good way of making a tangible difference. We're trying to protect a section of rainforest in Colombia.
Is there a lot of illegal logging in Colombia?
Yes, and it's a massive problem. The patch of forest we're looking at is one of the most exciting and biodiverse in the world. It has an amazing amount of wildlife that is only found there. It has the most poisonous animal on Earth, the golden dart frog, which is the size of your thumb and has enough poison in its skin to kill ten people, and it's only found there.
How bleak is this situation?
It's very serious. There are initiatives to make sure that the timber that comes into the UK is certified and comes from sustainable sources-that isn't the case for other countries around the world. Eighty per cent of Borneo's forest has gone in my lifetime. Colombia has a lot of legal and illegal logging and poaching. Lots of forest is laid waste and used for growing crops, and getting rid of the trees leads to soil erosion.
Is there any reason to be optimistic about environmental issues?
People are much more aware, are taking more responsibility for their actions and are thinking how we treat the planet. In the late 1990s things were very bleak- things were happening at an incredibly fast rate and people were unaware of it. Now people are willing to make changes. I work with young people and they are very aware we're overfishing our seas, the world's losing its sharks, we're destroying rainforests. They know about plastics in the sea and they're working on an enormous array of projects- things like banning plastic bags that end up floating around the sea killing turtles and certifying where timber comes from.
