World Development Movement campaigners collected postcards from hundreds of shoppers in Crosby Village calling for the government to reverse its green policy ahead of the Rio +20 Earth Summit.
The postcard which shoppers posted into a mini Trojan horse states: "This June the UN Earth Summit takes place in Rio. A key theme of the conference is the 'green economy'. This could be a very positive agenda that prioritises economic justice and sustainable development.
"But the version of a green economy being promoted by the UK government is a Trojan horse: it looks fantastic, but it could be deadly for the world's people and our planet."
The postcard then urges Bill Esterson to: "Please write to Nick Clegg (who will be going to Rio) to let him know that I do not support the UK's approach of ascribing a financial value to nature in order to bring it into the market.
"Such an approach will take control of natural resources away from poor communities, and pass them to distant unaccountable corporations, leading to further degradation of systems such as water, biodiversity and our climate."
Bill thanked Josephine and Chris Rawsthorne, Kathleen Zimak and the rest of the Crosby campaigners.
The Labour MP said: "The +20 Earth Summit is an opportunity for the government to take the lead in devising a green strategy which prioritises economic justice while encouraging sustainable development.
"Instead, the Deputy Prime Minister has gone to Rio selling the Tory-Lib Dem government's own agenda which puts the control of the world's natural resources, takes them out of the hands of the local communities and puts them in the hands of big business corporations whose ultimate goal is the bottom line.
"The World Development Movement's is correct in stating that the Tory-Lib Dem 'green economy' agenda is nothing more than a Trojan horse for bankers and unaccountable corporations."
Bill thanked everyone who took the time to fill in the postcards.
Bill said: "I received hundreds of postcards from people right here in Sefton Central. This shows the strength of feeling which people in this constituency have towards this issue.
"Nick Clegg has a real opportunity to make a valuable contribution to creating a fairer, greener world in Rio. But the Tory-Lib Dem policy does the opposite and will do more damage to the environment while penalising ordinary people throughout the world.
"This is the message I've passed on to the Deputy Prime Minister, only time will tell if he has listened."
