Soda and beer. Other than exhaling, bubbly drinks are our closest experience with releasing the greenhouse gas carbon dioxide. So as you confront steamy summer, which cold beverage is best—from an environmental perspective?

Massive, oil-lubricated supply chains feed even local craft breweries. And the unintended consequences of the high fructose corn syrup in your soda range from obesity to a dead zone in the Gulf of Mexico.

And then there are the containers. Aluminum is energy-intensive to mine, process and transform into cans—but the lightweight metal is also easily recycled. As are plastic soda bottles. So filling a washable, reusable cup with soda from a plastic container—and then recycling the big bottle—is the environmentally friendly thing to do.

Beer and soda also rely on water. And there's a lot more water in a drink than the drink, whether it's the water used to grow the grain that's fermented into beer or the cooling water required to produce the electricity that runs the soda bottling machines. Or you can cut out the middleman and just drink water. From the bottle-free tap.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
