On the eve of the COP15 United Nations Climate Change Conference, Greenpeace activists unfurl a giant banner carrying a message directed to President Luiz Inácio da Silva which reads in Portuguese ?Lula, you can do more for the climate: with zero deforestation, renewable energy and protection of the oceans." Greenpeace calls on world leaders gathering for the COP15 to agree to a legally binding deal and take personal responsibility for the future of climate change.
