The Live Earth organiser answers your questionsWhat is the one thing, the most urgent thing, that everyone can do to tackle global warming? Philip Mercer, LondonWell, first of all, learn about it. Learn about the ways in which you can become part of the solution to the problem in the contexts of your own life. Learning about it is important in your role as a citizen, and in helping to achieve the policy changes that in the long term will be required to solve this crisis.
Where individual actions are concerned, cut down on energy use. Become conscious as a consumer of picking the most environmentally friendly alternatives - and they are always there. You can make symbolic actions like changing lightbulbs to bulbs that use a tiny fraction of the energy, but remember that less visible changes that can accomplish the same thing are available for every product.
What do you think staging the Live Earth concerts will achieve? Don't you think there's a danger people will just enjoy the music and then forget about the issues? Ben Patterson, LiverpoolI'm relatively certain they'll enjoy the music, because the best acts in the world are playing. And I'm hopeful that Live Earth will serve as a unique opportunity to ask the entire world to hear the SOS for climate in crisis. Once we have their attention, we intend to launch a three-year campaign to put the solutions before every person in the world. I'm very optimistic that we'll have a chance to have a measurable difference.
