How can a member of the public take action to stem the threat of mass extinction and biodiversity loss?
Dan Janzen: The answer to this question depends totally on whether you live in Costa Rica, Pakistan, or Pennsylvania. The one I always give to Penn students is, ‘Get very good at what you do well and like doing well, get very rich at it in either money or capacity, and offer that to the conserved or conservable wildland that catches your fancy and is political/logistically most accessible to you.’ And if you cannot find one that can absorb your skills, our efforts in Costa Rican tropical conservation can always absorb such donations and put them to very good use.
David Yaden: Active support for policy changes and sustainable consumption seem most important, but some psychological factors may help to encourage these actions. My research has explored ‘the overview effect,’ a psychologically impactful experience that astronauts sometimes report after viewing Earth from orbit. A similar kind of mental shift, from a local to a global perspective, may help to motivate action on behalf of Earth as a whole.
Dan Garofalo: Reducing your carbon or ecological footprint will reduce pressure on the natural world and all the species that inhabit it. There’s no silver bullet, and there’s no secret lever that will protect ecosystems from our collective impact, but there are actions that we can take: Pay attention to where you live, how you commute, your purchasing/consumption habits, your travel footprint, and what you eat. Those five things tend to define your impact.
Joseph Kable, Baird Term Professor, Department of Psychology, School of Arts and Sciences: One thing people can do is prioritize these issues in their politics. Adequate tackling the issues raised in the U.N. report is going to require collective action at a large scale. While most people will say they are concerned about the environment if you directly ask them, very few volunteer environmental issues as one of the top concerns that drives their vote.
Daniel Aldana Cohen: The only remedy for the threats we face at the scale at which they confront us is massive political economic change. By far the most meaningful thing an individual person can do is join a social, political, or cultural movement aimed at transforming our political economy. No individual’s consumer choices and no group’s consumer choices are significant in the absence structural change.
Julie Ellis: I have three actions to recommend:
—Plant native species in your yard. Native plants are adapted to local environmental conditions, so they require fewer resources such as water. In addition, they provide habitat for birds, native pollinators, and many other species of wildlife. Many populations of native pollinators, including bumble bees and butterflies, are facing some degree of extinction risk. Planting native wildflowers can give these populations a boost.
—Reduce your plastic use, especially single-use items such as bags, straws, and flatware. There are a growing number of reusable and sustainable options for commonly used household products including toilet paper and toothbrushes made from bamboo and laundry detergent in biodegradable pods and compostable packaging. Talk to your local restaurants and coffee shops. Explain the problem of plastic pollution, and ask them to consider switching to sustainable, reusable materials. Make your voice heard and use your consumer power to pressure businesses to be more responsible in their resource use.
—Vote for representatives who support innovation in sustainable energy and renewable resources.
