Caroline Lucas - "You Ask The Questions"

The Independent, 11 August:

I am 24. Will there be a Green prime minister in my lifetime? And will it be you?
Helen Faulkner, Windsor, Berkshire

"Absolutely. After all, Labour went from their first MP to government in 24 years – and that was without the added urgency of external environmental pressures. But it's more likely to be someone from your generation than mine – maybe Norwich opposition leader Adrian Ramsay, who is likely to be our first deputy leader, and is just 26 – so I will be counting on him when I'm spending more time with my family!"

Why do so many British people still not believe in climate change?
Fraser Sullivan, Dorking, Surrey

"I think many people are genuinely confused – confused by a government that says climate change is the greatest threat that we face, and then gives the go-ahead to the largest expansion of aviation in a generation, and promotes the idea of more coal-fired power stations, like Kingsnorth."

What is the point of the Green Party when all the mainstream parties are embracing the environmental agenda?
Antonya King, Middlesborough

"All too often, other parties make 'green' all about 'taxes', and use it as an excuse to raise money from ordinary people. Any money collected through incentives to cut carbon should be invested in saving us money and energy, like Green councillors are doing by providing free insulation. Add to this the fact that the other parties also manage to have the wrong policies on everything from fighting inequality to preventing crime."
