It’s time for planetary-scale interventions to combat climate change — and environmentalist Tim Flannery thinks seaweed can help. In a bold talk, he shares the epic carbon-capturing potential of seaweed, explaining how oceangoing seaweed farms created on a massive scale could trap all the carbon we emit into the atmosphere. Learn more about this potentially planet-saving solution — and the work that’s still needed to get there.

What are some examples of ways food and drink producers are fighting the ever-growing torrent of plastic waste they have helped create? –Stacy Y., Raleigh, NC
As more people become aware of the extent of plastic waste clogging up our environment, cutting back on plastic use is fast becoming a key environmental priority around the world. According to a 2017 study by researchers from the University of Georgia, UC Santa Barbara and Sea Education Association, humans have produced 8.3 billion metric tons of plastic since mass-production started in the 1950s. While we’ve recycled about nine percent of all that plastic and incinerated another 12 percent, as much as 75 percent has been discarded into landfills or, even worse, set adrift into the environment. If we don’t slow down our current run rate of producing new (“virgin”) plastic, we can expect to add another four billion metric tons of it to our global environment by 2050.
With no cheap and scalable way to collect and get rid of all this plastic, the best we can hope for is to not make the problem worse. Luckily sustainable alternatives to plastic are coming on strong. PLA plastic, which is derived from plants and functions like conventional plastic, is promising but needs to scale up to become economically viable as it requires dedicated recycling/processing systems to truly “close its loop.” Likewise, paper or cardboard cartons could be a viable alternative to plastic food and drink storage containers if they are produced at great enough scale to justify dedicated facilities to process them for recycling, given that they are also infused with non-recyclable layers for strength and to prevent seepage.
PLA and cardboard are just the beginning of what is possible. Food producers and chemists are experimenting with making containers out of biodegradable plant products like corn starch, cassava and even algae. And just this spring, tens of thousands of runners participating in the London Marathon were given water out of edible pods made from seaweed and plant extracts instead of plastic bottles. Skipping Rocks Lab, the London-based startup behind the newfangled containers, reports that they’re not only cheaper to produce than plastic but are also biodegradable, breaking down completely within a month, while not imparting any flavor or taste to the water or whatever else is inside.

While there’s something to be said for technology, an older school “alternative” to plastic is all-natural plant material. American supermarkets could learn a lot from some Southeast Asian grocers, for instance, that wrap up produce for sale in biodegradable banana leaves instead of plastic bags. These all-natural wrappers can be thrown into the compost pile or yard waste bin and become rich soil without ever having to be processed using fossil-fuel based energy (like traditional recyclables).
You can do your part by telling your friends, neighbors, store managers, policymakers, elected officials and anyone else within hearing distance that you and millions of others like you don’t want any more single use plastics in your town, county, state or country. And if you haven’t already done so, get yourself a reusable water bottle and reusable shopping bag(s) so you can start being part of the day-to-day solution.
I’m looking for ideas for healthy, green snacks to have around the house and for packing with the kids’ lunches. Any ideas? –Mickey P., Salt Lake City, UT
There are so many healthy, green food options out there today that the work is no longer in finding them but is instead in choosing between them. One favorite for kids’ lunch boxes is gimMe Snacks roasted seaweed. Some 15 to 100 times more volume of seaweed can grow on the same footprint as lettuce. And while seaweed requires no water to produce, lettuce needs 15 gallons per pound. The entire gimMe product line is made with organic, non-GMO seaweed sustainably grown in South Korea.

Forager Project takes the skin, seeds and pulp that other food companies toss and rehydrates it into veggie chips that are like eco-friendly Doritos. Cheezy and Wasabi are among the company’s signature flavors. You won’t feel like a bad parent when your kids pull Forager Project chips out of their lunch boxes.
If you’re beyond milk, Modest Mylk could be just what you’re looking for. Purchasing just one (recyclable glass) jar gives you 42 servings of nut mylk and saves 11 milk cartons from going to the landfill. When blended for just 60 seconds with water, the shelf-stable base creates fresh homemade nut mylk—free from carrageenan, gums, emulsifiers, preservatives, and artificial ingredients.
Another favorite non-dairy treat is Nuttzo, which makes nut butters without using antibiotics, growth hormones, pesticides or fertilizers—and with ingredients farmed under national standards of renewable resources and soil and water conservation. It’s Organic Power Fuel Chocolate spread has cashews, brazil nuts, almonds, flax seeds, chia seeds, hazelnuts, pumpkin seeds, chocolate and sea salt—and no palm oil.
Stonyfield Organic, which started as an organic farming school before adding on yogurt production some 35 years ago, still supports the planet through renewable energy and packaging its products in plant-made material instead of plastic. Snack lovers young and old still love their organic string cheese, fruity cows, graham crackers and cookies, not to mention the New Hampshire company’s signature yogurt.
Since its beginnings at an Austin, Texas farmers market in 2009, GoodPop’s frozen pops have always been made with non-GMO, Fair Trade Certified, rBST-free, organic and locally sourced ingredients. We like Cookies N’ Cream and Banana Cinnamon, but you might be more the Chocolate Milk or Watermelon Agave type. GoodPops are made with whole foods and never concentrates, extracts or artificial flavors.
Alter Eco’s tagline “Enlightened Indulgence” perfectly describes this green-minded chocolate company’s ethos. Whether you like truffles, caramels, smothered almonds or just good old-fashioned chocolates, Alter Eco lets you enjoy without the environmental guilt, as their Swiss-made chocolate is crafted from organic cacao by farmers who are replanting South American rainforests.
There are plenty of other ideas out there. Just browse the aisles of Whole Foods and you’ll find lots of other choices. And don’t forget about good old-fashioned fruit and veggies. Crunchy carrots, juicy apples and tart blueberries never go out of style on the kitchen counter or in the lunch box.
