Mr. Jamie Walker

I prefer to give climate change the "cold" shoulder. Also, I think peak oil issues - see for example http://www.theoildrum.com - and resource problems - water, soil, animal populations - are critical as well, and we should consider these areas together to arrive at the best solutions.

I do not want to just sit and watch it all go wrong. I want my children and their children to be able to enjoy the world as it is now, and I want to make as many people aware that they can change the negative trend of our existence on this planet.

We have to act now

We must all do our best to live as sustainably as possible. Our government is taking too long so the people must lead by example, market pressure and peaceful but direct action.

I believe it is the greatest challenge facing humanity and one already affecting people especially in Africa. But it is also presents a wonderful opportunity to create a more just and saner world.

Undoubtedly the number one challenge that our generation faces - and our world.
