Humor can be offensive and divisive, especially jokes about sensitive issues, such as race and religion. But research is showing religious humor also can have a big upside, one that can help us move past religious stereotypes that divide communities, nations and regions.

The landmark encyclical from Pope Francis calling on the world to engage in a new dialogue about how we are shaping the future of our planet is one example of a growing religious environmentalism. Amid a global financial downturn, religious groups, with their commitments to both caring for the Earth and human development, are uniquely positioned to help seek ways to develop public policies that balance economic needs with the protection of the planet. But do they have the will, and are people ready to listen?
