 So, one thing that I work with is climate change a lot, of course, and just some of the statistics and numbers are kind of staggering, and if you can put that in economic terms as well, if you can frame it in dollars and cents, you're going to have the attention of a lot of policymakers a lot more effectively than if it were just numbers. Other thing we can do is simple lifestyle changes if we have the means to do so. One thing is taking reusable shopping bags to the shopping market, combining trips to the grocery store, doing simple things like that, taking shorter showers. I currently live in San Francisco, California's in the middle of a drought. We hear about water saving use all the time, and not just water saving use but energy efficiency. California has great carbon emission standards, and these are things that youth can get involved in and learn about and actively seek to facilitate discussion of with their governmental leaders.
