We can and must tackle climate change and the economic downturn together.

On 2 April, 20 world leaders (the G20) meet in London to talk about the global financial crisis.

However even before the recent banking collapse, the world was already suffering poverty, inequality and the threat of climate chaos.

Our future depends on creating an economy based on the fair distribution of wealth, decent jobs for all and a low carbon world. Sign this petition to get your message to the G20, and add the petition to your Facebook page.

On Saturday 28th March join us and thousands of others on the Put People First march in London from 10.30am at Temple Place to Hyde Park. (From 2pm onwards in Hyde Park there will be a carnival with speakers and entertainment.)

We will be Tweeting from the event, and it would be great if you would like to join the throng of Put People First tweets by adding #g20rally when you tweet on the day - see here for the ongoing conversations on Twitter.

The lineup currently looks like this:

Music and comedy

Singer/songwriter Luke Pritchard from The Kooks
Mauritanian musician Daby Toure
Comedian and activist Mark Thomas

Speakers

Global Call to Action Against Poverty (GCAP) Co-chair Kumi Naidoo
International Trade Union Confederation President Sharan Burrow
Brendan Barber, TUC General Secretary
Global Justice author Susan George
Mary Turner, President of the GMB
Environmentalist Tony Juniper
Derek Skinner, UNITE Joint General Secretary
Tony Woodley, UNITE Joint General Secretary
Global Justice campaigner, Mary Lou Malig, from Focus on the Global South
Dave Prentis, UNISON General Secretary

This is a great opportunity to tell the G20 to 'Put People First'.
We need you to march so world leaders get this strong message.

You can add the event to your Facebook and Upcoming.
