As part of the World Forum on Enterprise and the Environment, the Guardian has pulled together a panel of experts to answer the ‘top ten’ questions posed by readers. Readers are asked to submit their questions to panellists, who include Prof. Sir David King, and Pavan Sukhdev, leader of the TEEB (The Economics of Ecosystems and the Environment) study, with the answers appearing online within the next couple of weeks.

This year, the theme of the World Forum, run by the Smith School of Enterprise and the Environment at Oxford University, is ‘Ecosystem Services: From New Commitments to Strategic Action‘.
