At a meeting in Bolivia's Cochabamba region, activists and left-wing leaders emphasized the need for major polluting countries to significantly reduce greenhouse gases and consider input from smaller nations in order to combat global warming. They criticized the closed-door negotiations of the failed Copenhagen summit in December and called for a more inclusive approach at the upcoming climate change meeting in Mexico. The Cochabamba summit proposed a 50 percent reduction in emissions by leading industrial nations, a more ambitious target than the Copenhagen Accord's pledges of 7 to 16 percent cuts. Bolivian President Evo Morales urged developed countries to prioritize the well-being of all people in their decision-making process at the Mexico meeting. During the summit, Morales caused controversy by suggesting that consuming hormone-fed chicken leads to "sexual deviation" in men and that European men experience hair loss due to genetically modified food. The World People's Conference on Climate Change and the Rights of Mother Earth, attended by 20,000 environmentalists and representatives from 90 governments, targeted capitalism, genetically modified food, and global warming. Indigenous groups from various countries participated in the event in Tiquipaya, which featured concerts, theater, a handicrafts market, and artists painting murals. Bolivia, Venezuela, Cuba, Nicaragua, Ecuador, Sudan, and Saudi Arabia, all critics of the Copenhagen accord, could support resolutions despite being smaller countries. The crisis of climate change, predominantly affecting southern regions, was emphasized at the conference. Canadian author Naomi Klein stated that if the simple fact of justice and decency is acknowledged, southern countries will no longer need to beg for aid. Klein, a well-known activist against global warming, believes that the meeting in Cochabamba could strengthen an alliance among nations already facing the impacts of climate change. She emphasized the importance of unity among developing countries and proposed the creation of an international tribunal to hold accountable those responsible for global warming. Additionally, the meeting called for a global referendum on climate change and the establishment of a fund to assist nations dealing with the effects of global warming. The resolutions from the summit are not mandatory, but countries and social organizations who participated have committed to garnering support for them leading up to the United Nations summit on climate change in Cancun, Mexico in December. Alicia Barcena, the top UN representative at the meeting, expressed on Tuesday that it was time for the organization to acknowledge that grassroots groups were excluded from the Copenhagen summit. She expressed doubt about the effectiveness of the Cancun summit, stating that Rio+20 should be the focus, as she believes Cancun will not resolve the issues. In late 2010, the UN General Assembly passed a resolution to host the Rio+20 Earth Summit on Sustainable Development in Rio de Janeiro in 2012.
