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.

Last Wild Grove of Wollemi Pines, the Endangered ‘Dinosaur Trees,’ Saved From Australia's Wildfires

Almost three decades after they were rediscovered, the ancient "dinosaur trees" of Australia's Wollemi National Park were nearly wiped out for good. Wildlife officials in New South Wales feared that the last natural stand of Wollemi pines would be counted among the billions of plants and animals destroyed by Australia's recent wave of wildfires. But thanks to quick action from firefighters, the ancient grove has been saved, The Guardian reports.

The first Wollemi pines date as far back as 200 million years, and the trees reached peak numbers 65 million to 34 million years ago. Since then, populations have shrunk so drastically that the species was thought to be extinct until it was rediscovered 26 years ago. Fewer than 200 wild specimens exist today, and they're all concentrated in a protected sandstone grove in Wollemi National Park, about 125 miles northwest of Sydney, Australia.

The Wollemi pines' fragile status means that one bad forest fire could spell its end. With this in mind, the New South Wales National Parks and Wildlife Service and NSW Rural Fire Service prioritized their protection this bushfire season. Before the Gospers Mountain fire spread to the canyons where the trees grow, a team of firefighters was sent there by helicopter to install an irrigation system. This kept the trees hydrated and made them less vulnerable to flames. Helicopters also dumped fire retardant around the grove to weaken the fire when it arrived.

The efforts weren't able be able to save every Wollemi pine from damage and destruction—a few trees survived with charring and two more died—but they were enough ensure the continuation of the species. With a population this small, protecting it is a never-ending battle. In addition to fire, visitors stepping on seedlings and introducing diseases also pose a threat. For that reason, the Australian government has chosen to hide the exact location of the grove from the public.

Eco-Friendly, Reusable Deodorant Containers Are Good for the Earth and Your Pits

Myro

A fair amount of plastic goes into keeping your armpits smelling fresh. Few of us recycle our empty deodorant tube after swiping on that last layer, after all. In many cases, it’s not even clear if you can, though there are a few special recycling programs that make it possible. But one company aims to make it easier to both smell clean and keep the planet clean.

Myro deodorant comes in refillable, reusable packaging, as Design Milk reports. The essential-oil-based deodorant comes in pods that you can pop into colorful reusable canisters. Created by the award-winning industrial designers at the New York studio Visibility, the fashionable containers are also made with 50 percent less plastic than most drugstore deodorant sticks, according to the company.

The deodorant sticks aren’t fundamentally different than something you might pick up at the drug store, even if they would look more at home on the shelves at Urban Outfitters or Anthropologie than CVS. You use a dial at the bottom of the tube to advance the deodorant stick, and when you reach the end of the deodorant, the pod that held the formula pops out. You can then refill it with one of Myro’s replacement pods. If your container needs a deep clean, you can stick it in the top rack of your dishwasher.

The deodorant itself doesn’t use the standard aluminum or baking powder formula, instead employing an antimicrobial agent made from sugar to reduce smells and barley powder to absorb moisture.

Myro deodorant comes in five different scents that you can mix and match with five different packaging colors. There’s Solar Flare, a mix of orange, juniper, and sunflower; Big Dipper, a blend of bergamot, lavender, and vetiver; Cabin No. 5, which smells like vetiver, patchouli, and geranium; Pillow Talk, made with violet leaf, ylang ylang, wild amyris; and Chill Wave, a blend of cucumber, jasmine, and spearmint.

One Myro deodorant, including the refillable container, costs $10 and can either be bought one at a time or through a subscription that ships refills every three, four, or six months. The refills can also be purchased one at a time. Customers that subscribe will receive free shipping, while one-time purchases will include a $5 shipping fee. You can pause your subscription or switch scents at any time.
