Your Bacon, Egg, and Cheese Sandwiches Have a Hefty Carbon Footprint

Most people know that eating meat, especially red meat—say, hamburgers—is bad for the environment. Raising enough methane-farting, resource-intensive cows to satisfy our cravings for burgers and steaks produces an outsized carbon footprint that plays a significant role in climate change. But what about your breakfast egg-and-cheese? A new study says you should feel guilty about that, too.

Recent findings reported in the journal Sustainable Production and Consumption examine the carbon footprint of 40 different kinds of sandwiches—from the simple ham and cheese to tuna, BLTs, and breakfast sandwiches—both homemade and pre-packaged. Researchers from the University of Manchester calculated the carbon necessary to produce standard recipes, including the agriculture required for the ingredients, the manufacturing of the packaging materials, the refrigeration required to keep the sandwiches cold, and the waste generated. They sourced their estimates from previous studies on the carbon footprint of producing and transporting ingredients like bread, ham, bacon, lettuce, tomato, and canned tuna as well as the energy cost of manufacturing packaging, transporting materials, and taking waste to the landfill.

They found that of all the sandwiches, those that combined pork (or prawns, because prawn and mayonnaise sandwiches are apparently a popular thing) and cheese are the most carbon-intensive. A bacon, egg, and cheese breakfast sandwich clocked in as the most environmentally taxing sandwich of them all, with a carbon footprint of 1441 grams CO2 equivalent—a measurement of the global warming potential—per sandwich. (The diet of the average meat-eater in the UK produces about 7200 grams CO2 equivalent daily. For comparison, if you drive your car four miles, it emits about 1650 grams CO2, roughly.)

Chicken and tuna sandwiches were slightly less carbon-intensive, but vegetarian sandwiches didn't fare as well as you might think—depending on how much and what type of cheese was involved, they could have carbon footprints as high as some of the meat sandwiches.

The researchers suggest that some improvements to the way sandwiches are produced and sold might decrease their carbon footprint by as much as 50 percent. Reducing the amount of meat, eggs, and cheese used, excluding tomato, lettuce, or mayo, reducing packaging, and other changes could all contribute to shrinking a sandwich's carbon footprint. Unfortunately, here's a limit to how much a sandwich's environmental impact can be reduced. You can't really have a BLT without the B, L, or T.

But if you're making it instead of buying it, you're saving a lot of emissions. As you might expect given the environmental cost of packaging, ready-made commercial sandwiches had a much bigger carbon footprint than their homemade counterparts containing the same ingredients—2.2 times larger, in fact.

Just another reason to feel guilty about not bringing your own lunch from home.

Ocean Explorer Jean-Michel Cousteau's Tips for Dealing With Seasickness

Jean-Michel Cousteau—son of the iconic documentary filmmaker and conservationist Jacques Cousteau—claims to have never experienced seasickness himself. The 80-year-old explorer attributes his luck to the amount of time he's spent on boats filming nature documentaries, exploring marine environments, and raising awareness about conservation issues. So what advice does he have when his shipmates start to look a little green around the gills? Thrillist recently reached out to him for an answer.

Cousteau has seen a fellow sailor succumb to the nausea-inducing rocking of a ship many times. When this happens, he says the best thing to do is avoid the bow, or the front of the ship, but resist the urge to hide out below deck—away from any views of the ocean. Motion sickness occurs when the information sensed by our inner ear doesn't match up with what we see in front of us: In the case of sea travel, this could mean you feel the floor of the boat shifting beneath you while the wall of the galley appears to stay still.

Rather than forcing yourself to forget where you are, Cousteau says the most effective approach is to embrace your enemy. Look out at the water and try to appreciate the sights. Staring intently at the horizon will also help re-balance what you're seeing with what you're sensing. Soon you won't be focusing on that queasy feeling in your stomach. “Suddenly, instead of not feeling well, they’re distracted by our profound connection to the oceans," Cousteau told Thrillist.

And if all else fails and your boat is nowhere near dry land, Cousteau suggests a very Cousteau-esque solution: Slip on your scuba gear and get in the water. Of course, that may not be an option depending on what type of voyage you're on. If that's the case, you may want to consider these more conventional motion sickness remedies.

A Team of Cigarette Butt-Collecting Birds Are Keeping a French Theme Park Litter-Free

The six rooks pecking at litter within the Puy du Fou theme park in Les Epesses, France, aren't unwelcome pests: They're part of the staff. As AFP reports, the trained birds have been dispatched to clean up garbage and cigarettes butts from the park grounds.

Rooks are a member of the corvid family, a group of intelligent birds that also includes ravens and crows. At Puy du Fou, an educational amusement park with attractions inspired by various periods from French history, the rooks will flit around the park, pick up any bits of litter that haven't been properly disposed of, and deliver them to a receptacle in exchange for a treat. At least that's how the system is set up to work: The full team of six rooks has only been on the job since August 13.

Employing birds as trash collectors may seem far-fetched, but the experiment has precedent. The Dutch startup Crowded Cities recently started training crows to gather cigarette butts using a vending machine-like device. Once the crows were taught to associate the rig with free peanuts, the machine was tweaked so that it only dispensed food when the crow nudged a cigarette butt resting on a ledge into the receptacle. The cigarette butts were eventually removed, and the birds figured out that they had to find the litter in the wild if they wanted to continue receiving their snacks.

Crowded Cities had planned to conduct more research on the method's effectiveness, as well as the potentially harmful effects of tobacco on crows, before bringing their vending machines to public spaces. Puy du Fou, meanwhile, has become one of the first—if not the first—businesses to fully implement the strategy on a major scale.

Even if it doesn't prove to be practical, Puy du Fou president Nicolas de Villiers told AFP that cleaning up the park is only part of the goal. He also hopes the birds will demonstrate that "nature itself can teach us to take care of the environment."
