How to Drink a 'Green' Beer on St. Patrick’s Day
By Susan Bird
Your St. Patty’s Day beer may be tinted an amusing and pretty shade of green this week, but have you ever considered how eco-friendly and sustainable your beloved brewskies really are? If you want to ensure you’re maintaining your environmentalist credentials while hoisting a few brews, keep these considerations in mind:
Keg, Can or Bottle?

The keg is king. Besides being handy for large gatherings, rented beer kegs are reused about twice a month or 22 times a year. Kegs are durable enough to last two decades. Using them means that about 58,000 fewer beer cans and bottles get tossed into the trash every year.
Even in a restaurant or bar, beer on tap from a keg is almost always the more eco-friendly choice than from an individual bottle or can. This is true even after taking into account the need to truck the beer from brewery to bar, as well as the need to wash the glasses.
The Bottle vs. The Can
If your choices are limited to bottled or canned beer, your instinct might be to choose a bottle. They can be washed and reused, so they seem to be the greener choice, right? Not so fast. This is a subject of some debate.
“Generally speaking, every time you drink a can of beer and you recycle it, some part of that can will be back up in a shop within the next 60 days,” Kim Moratta, MillerCoors’ director of social sustainability, told OPB.org. “The other part that’s interesting is that if you make a can out of recycled content, it requires 95 percent less energy.”
Fans of the bottle, however, say that if you consider a container’s entire life cycle and the manner in which it is made, bottles clearly win. In part, this is because most of the bauxite required to manufacture aluminum cans comes from environmentally damaging mining operations in Jamaica, Guinea and Australia.
“Recycling 100 beer bottles requires more energy than recycling 100 aluminum cans, but making the aluminum cans requires a lot more energy,” David Allaway, a solid waste policy analyst at Oregon Department of Environmental Quality, told OPB.org.
No clear winner here, then, which is why drinking locally produced beer winds up a greener choice than either bottles or cans.
Think Globally, Drink Locally

If your goal is reducing the carbon footprint of the beer you drink, choose locally brewed beverages. Many craft brewers now source their hops and grain locally, reducing the pollution that inevitably results from shipping beer ingredients across the country or around the globe.
Look for craft brewers who go the extra mile to respect the environment in ways like these:
- Using heat from the brewing process to heat office space and other structures
- Using spent grain as a co-fuel for beer production, which can reduce energy consumption by as much as 70 percent a year
- Using organically grown ingredients
- Using wastewater creatively, infusing it with microorganisms that turn it into gaseous fuels like methane or hydrogen
- Using water efficiently, such as harvesting rainwater and minimizing evaporation
- Preventing spent sediment, yeast, proteins and grains from ending up in landfills by sending them to special processing facilities instead
- Using wind or solar energy to power production
Now that you have the facts, get out there and enjoy a few eco-friendly beers. Remember to drink responsibly, designate a driver and minimize your impact on Mother Nature.

At first glance, you wouldn't think avocados and almonds could harm bees; but a closer look at how these popular crops are produced reveals their potentially detrimental effect on pollinators.
Migratory beekeeping involves trucking millions of bees across the U.S. to pollinate different crops, including avocados and almonds. Timothy Paule II / Pexels / CC0<p>According to <a href="https://www.fromthegrapevine.com/israeli-kitchen/beekeeping-how-to-keep-bees" target="_blank">From the Grapevine</a>, American avocados also fully depend on bees' pollination to produce fruit, so farmers have turned to migratory beekeeping as well to fill the void left by wild populations.</p><p>U.S. farmers have become reliant upon the practice, but migratory beekeeping has been called exploitative and harmful to bees. <a href="https://www.cnn.com/2019/05/10/health/avocado-almond-vegan-partner/index.html" target="_blank">CNN</a> reported that commercial beekeeping may injure or kill bees and that transporting them to pollinate crops appears to negatively affect their health and lifespan. Because the honeybees are forced to gather pollen and nectar from a single, monoculture crop — the one they've been brought in to pollinate — they are deprived of their normal diet, which is more diverse and nourishing as it's comprised of a variety of pollens and nectars, Scientific American reported.</p><p>Scientific American added how getting shuttled from crop to crop and field to field across the country boomerangs the bees between feast and famine, especially once the blooms they were brought in to fertilize end.</p><p>Plus, the artificial mass influx of bees guarantees spreading viruses, mites and fungi between the insects as they collide in midair and crawl over each other in their hives, Scientific American reported. According to CNN, some researchers argue that this explains why so many bees die each winter, and even why entire hives suddenly die off in a phenomenon called colony collapse disorder.</p>
Avocado and almond crops depend on bees for proper pollination.

Many have opted to salvage what partial colonies survive and move away from agricultural areas.</p><p>The future of pollinators and the crops they help create is uncertain. According to the United Nations, nearly half of insect pollinators, particularly bees and butterflies, risk global extinction, Phys.org reported. Their decline already has cascading consequences for the economy and beyond. Roughly 1.4 billion jobs and three-quarters of all crops around the world depend on bees and other pollinators for free fertilization services worth billions of dollars, Phys.org noted. Losing wild and native bees could <a href="https://www.ecowatch.com/wild-bees-crop-shortage-2646849232.html" target="_self">trigger food security issues</a>.</p><p>Salazar, the beekeeper, warned Phys.org, "The bee is a bioindicator. If bees are dying, what other insects beneficial to the environment... are dying?"</p>

Australia is one of the most biodiverse countries in the world. It is home to more than 7% of all the world's plant and animal species, many of which are endemic. One such species, the Pharohylaeus lactiferus bee, was recently rediscovered after spending nearly 100 years out of sight from humans.
Scientists have newly photographed three species of shark that can glow in the dark, according to a study published in Frontiers in Marine Science last month.
