The international community is facing a stark and serious choice, "either to improve or to destroy the environment," Pope Francis said, referring to the upcoming climate change summit in Paris.
"It would be sad, and I dare say even catastrophic, were special interests to prevail over the common good," the pope said Nov. 26 during a visit to the headquarters in Nairobi of the U.N. Environment Program and U.N. Habitat, an agency concerned with urban planning.
Under the auspices of the United Nations, the Paris conference Nov. 30-Dec. 11 has the aim of achieving a legally binding and universal agreement on measures to stem climate change and protect the environment.
Pope Francis spoke at length about the importance of the conference during his visit to the U.N. offices, and his top aides had a meeting the evening before with Kenya's environment minister and other officials to discuss their hopes and strategies for the Paris meeting.
On his way into the meeting with U.N. officials and diplomats accredited to the two U.N. agencies, Pope Francis planted a tree.
While his speech contained ample quotes from his June encyclical on the environment, the pope also referred several times to the significance of planting trees and borrowed several lines from a speech he in made in Bolivia in July to a variety of grassroots movements advocating for justice for the poor.
In fact, just as in the encyclical, Laudato si', the pope insisted in Nairobi that there is a close connection between environmental destruction and unjust economic and political policies that penalize the poor.
"We are faced with a great political and economic obligation to rethink and correct the dysfunctions and distortions of the current model of development," he said, especially because of their emphasis on exploiting natural resources, but not sharing the benefits with local communities.
Planting a tree, he said, is an "invitation to continue the battle against phenomena like deforestation and desertification," as well as "an incentive to keep trusting, hoping and above all working in practice to reverse all those situations of injustice and deterioration which we currently experience."
The Paris conference, the pope said, "represents an important stage in the process of developing a new energy system which depends on a minimal use of fossil fuels, aims at energy efficiency and makes use of energy sources with little or no carbon content."
Pope Francis told those gathered at Nairobi's U.N. offices that he hopes the Paris conference will result in a "global and 'transformational' agreement based on the principles of solidarity, justice, equality and participation; an agreement which targets three complex and interdependent goals: lessening the impact of climate change, fighting poverty and ensuring respect for human dignity."
To achieve a comprehensive and fair agreement, he said, real dialogue is necessary among politicians, scientists, business leaders and representatives of civil society, including the poorest sectors of those societies.
