We don’t have to wait out the Trump administration to address the issue of climate change. Cities are a major cause of the problem, and more than 100 are working together to decrease emissions around the world. Individuals can lower the level of methane and eat a healthier diet at the same time. Research shows it’s also important to start talking about climate change with friends, families and others. Some 70% of Americans agree it’s really happening, so there’s no reason to shy away from a “controversial subject.” Recognizing that fact will help build a consensus for action.
