Climate change is an enormous global problem — and thinking about how you alone can help tackle it can feel overwhelming, to say the least. It's completely normal to question whether one person can make a difference in the fight against climate change, but don't discount your voice just yet. According to climate and environmental science experts, personal conservation and advocacy efforts play a key role in protecting the planet and influencing others to get on board. While personal conservation efforts are important, experts stress that pushing for larger climate change solutions is just as crucial. "The structural changes needed to decrease reliance on fossil fuels need large policy changes," Dr. Amir Jina, Ph.D., an assistant professor at the University of Chicago's Harris School of Public Policy and member of the Lab, tells Bustle. "Using your voice to call for changes, through voting, protest, writing, art, or any other kind of activism, is the best way to motivate creative policies that will bring about solutions." Jina adds that it's important to remain consistently committed to activism because "it's not a sprint, it's a marathon, and changes won't happen overnight."
