Activists and left-wing leaders at a meeting in Bolivia's Cochabamba region concluded that big polluting countries need to aggressively reduce greenhouse gases and consider input from smaller nations in order to combat global warming. The gathering was seen as an alternative to the unsuccessful Copenhagen summit, where countries and environmental groups felt excluded from decision-making. The activists criticized the industrial powers for not agreeing to significant cuts in emissions at Copenhagen and called for a more ambitious goal of a 50 percent reduction in emissions by leading nations. Bolivian President Evo Morales emphasized the need for developed countries to listen to the voices of the people and make decisions that benefit everyone at the upcoming climate change meeting in Mexico. Earlier at the summit, Morales sparked controversy by claiming that consuming chicken fed with hormones can lead to "sexual deviation" in men, and suggesting that European men experience hair loss due to consuming 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 around the world participated in the event in Tiquipaya, which featured various activities such as concerts, theater, a handicrafts market, and artists painting murals. Bolivia, Venezuela, Cuba, Nicaragua, Ecuador, Sudan, and Saudi Arabia, all part of a leftist group of Latin American countries, have been vocal critics of the Copenhagen accord, with Morales stating that the crisis of climate change was created in the north and its effects are predominantly felt in the south. Canadian author Naomi Klein stated that if the simple fact of justice and decency is acknowledged, it means that southern countries are no longer asking for aid. Klein, who is known for her activism against global warming, believes that the meeting in Cochabamba could help build a stronger alliance among nations already experiencing the impacts of climate change. She emphasized the importance of unity between developing countries and noted that this empowered position calls for more cooperation. The meeting in Cochabamba resulted in a resolution to establish an international tribunal to hold those responsible for global warming accountable. Additionally, it called for a global referendum on climate change and the creation of a fund to support nations affected by global warming. The resolutions from the summit are not mandatory, but countries and social organizations who participated have committed to garnering support for them before the United Nations summit on climate change in Cancun, Mexico in December. Alicia Barcena, the top UN representative at the meeting, acknowledged on Tuesday that grassroots groups were excluded from the Copenhagen summit and expressed doubt about the effectiveness of the Cancun summit. She suggested that the Rio+20 Earth Summit on Sustainable Development in Rio de Janeiro in 2012 should be the ultimate goal, as she believes Cancun will not be able to address the issues adequately.
