The scale of our climate challenge is staggering: humans have pumped 1.6 trillion tonnes of carbon dioxide into the air and oceans since 1750, and we’re adding another 40 billion tonnes every year. Even with dramatic emissions reductions, we’re still on track to blow past 1.5 degrees of warming, the Paris Accord target first breached in 2024. Tune in to a conversation with Dr. Julio Friedmann, Chief Scientist at Carbon Direct. This carbon management company partners with Fortune 500 companies such as Microsoft, JPMorgan Chase, and American Express to transform net-zero commitments into science-backed action plans. After a career that began as a researcher at ExxonMobil and included service at Lawrence Livermore National Laboratory, Columbia University’s energy policy center, and running advanced energy programs in the Obama administration’s Department of Energy, Julio brings unique expertise to the intersection of massive climate challenges and current technological capabilities.

As companies work toward 2030 and 2050 carbon goals, the question isn’t whether we’ll need massive carbon removal—it’s whether we can deploy it fast enough and fairly enough to matter. The recent $100 million XPRIZE Carbon Removal awards highlighted the diversity of approaches being pursued, with natural solutions like enhanced rock weathering using basalt and azomite soil, and biochar applications to farmland dominating the winners. But how do these technologies stack up against the hype? Friedmann provides a realistic assessment of where Direct Air Capture, ocean alkalinity enhancement, and other carbon removal approaches stand today. Carbon Direct’s team of 70+ scientists changes the conversation with corporate clients about their carbon strategies, providing the scientific firepower to offer hard feedback about what’s needed to preserve the markets, supply chains, and revenue streams companies depend on.

Infographic: Tips for an Environmentally Responsible, Low-Maintenance Yard
Spring is officially here, inspiring gardening plans as well as dread of lawn chores. Before you immerse yourself in another year of yard maintenance, we have a question for you: When was the last time you reevaluated your yard maintenance tactics and outdoor plant selections? An environmentally friendly approach to a low-maintenance yard can save you money, time, and effort while it benefits the local ecosystem.
By carefully selecting the right plants, including natives and perennials, you can minimize watering and yearly plantings — resulting in less work for you and a lower water bill. And by employing natural gardening techniques, such as composting and companion planting, you can keep your soil healthy and keep pests away — without chemicals.
Naturally, a healthy and biodiverse yard looks different depending on your climate and region. Are you familiar with the plants that are native to your region? It’s exciting to choose the optimal plants for your garden because you know you’re giving them the best chance of success — plus, you’re helping the surrounding ecosystem.
Before selecting your plants, be sure to check the noxious weed lists or your county extension office to make sure you don’t pick invasive plant species. Some low-maintenance plants may be invasive in your region. For example, English Ivy, an attractive, low-maintenance vine, is an aggressive invader and on the noxious weed of the United States list.
With careful plant selection and eco-friendly gardening strategies, you’ll enjoy a low-maintenance yard, save money, and benefit Mother Earth too! Check out the tips and plant recommendations in the following infographic from HomeAdvisor.

Classic Sustainability In Your Ear: Coastal Flooding in 2050 With Climate Scientist James Renwick
Turn back the clock to hear an early warning from James Renwick, co-author of the upcoming 2021 United Nations Intergovernmental Panel on Climate Change (UNIPCC) report and head of the School of Geography, Environment and Earth Sciences at Victoria University, Wellington, New Zealand, joins Earth911 to discuss the prospects for coastal flooding due to climate change. He shares troubling but important insights into how much seas have already risen since the 1800s — about one foot — and the potential for up to two feet more flooding in the coming century. He also reports the UNIPCC will acknowledge that the critical 1.5C warming threshold is locked in unless the world takes radical action to reduce emissions immediately. Humanity has already committed future generations to potentially disastrous climate impacts, he says.
Renwick explains how much water is stored in Antarctica and the projections for economic and housing losses along the U.S. East Coast, which is particularly prone to flooding because of the configuration of ocean currents. He also discusses the growing accuracy of climate models and how accelerated warming seen in recent years appears poised to continue speeding ice loss at the poles. But, Renwick argues, the international climate dialogue has shifted from resistance to acknowledgment of climate impacts and growing national and local action, which gives him hope. “Things are moving in the right direction,” he told Earth911’s Mitch Ratcliffe. “But we’ve got a lot of work to do.”
The upcoming COP26 meeting of global leaders, which was postponed to the fall of 2021 due to the pandemic, will feature many nations’ increased commitments to reduce emissions. In the meantime, he urges individual citizens to speak out and choose sustainably produced products, as well as support effective local remediation projects, such as tree-planting programs. Each of us can make a difference. Start your journey with this conversation with Professor James Renwick.

7 DIY Recycled Bird Feeders
Before you throw away that empty soda bottle, wine bottle, or milk carton, think about turning it into a bird feeder.
These seven DIY projects show how to reuse common household items to make useful backyard wildlife stations. There’s something for everyone, whether you’re crafting with kids or have experience with tools. Whenever possible, choose glass instead of plastic. Experts say glass bottles last longer in the sun and are easier to clean than plastic.
This article contains affiliate links that help fund our work.
1. Soda Bottle Bird Feeder

The soda bottle bird feeder is a classic project that’s easy for anyone to make. Start by saving a 1- or 2-liter soda bottle from the recycling bin. Then, find two wooden spoons, dowels, or sturdy twigs from around your home or yard. These will serve as perches for the birds.
To make one, follow the instructions from Gardening Know How: mark two sets of holes at right angles, insert the spoons or dowels, fill the bottle with birdseed, put the cap back on, and hang it up with string or fishing line. If you’re working with young kids, adults should handle the cutting.
If you prefer not to do DIY from scratch, you can buy soda bottle bird feeder kits. Just attach the tray and wire to your own bottle.
2. Milk Carton Bird Feeder
Making a bird feeder from a milk or juice carton is just as easy as using a soda bottle. The Audubon Society even has a version that’s great for kids. Cut a large opening a few inches from the bottom on one side, add a stick underneath for a perch, make two small holes at the top for hanging, decorate it, and fill with birdseed.
Keep in mind that milk cartons don’t last as long as plastic or glass feeders. Watch for signs of wear and replace your feeder when needed. Remember to recycle the old carton.
3. Tray Bird Feeder

If you have leftover wood from a home project, you can make a simple tray feeder using Birds & Blooms’ instructions. You’ll need cedar or pine scraps, an aluminum screen for drainage, panel nails, eye screws, and some chain for hanging. You should also be comfortable using a drill and hammer.
You can also reuse old windows, picture frames, or other wooden items from around the house to make a tray feeder. One Instructables tutorial shows how someone built a feeder from the wooden backing of an old bronze award.
Tray feeders bring in many types of birds, like cardinals, chickadees, woodpeckers, and mourning doves. However, they don’t keep out squirrels.
4. Floppy Disk Bird Feeder
If you have some old floppy disks lying around, you can turn them into a retro bird feeder using an Instructables guide.
You’ll need to take apart three disks, remove the magnetic film, cut a window for the seeds, put the pieces together to form a cube, and attach a string for hanging. Use tape or a hot glue gun to hold it together, then add birdseed inside.
5. Self-Refilling Glass Bottle Bird Feeder
This gravity-fed feeder is a smart upgrade from basic designs. Remodelaholic’s wine bottle bird feeder tutorial explains how to build a simple wooden platform with a notched holder that keeps an upside-down glass bottle just above the seed tray. As birds eat, gravity refills the tray with more seed.
You need only a recycled wine bottle (or any narrow-neck glass bottle) and some wood for this project. The screw-based mount makes it easy to remove the bottle for refilling. Use a low- or no-VOC wood sealer to protect the frame.
6. Plastic Bottle Hummingbird Feeder
Want to bring hummingbirds to your yard? Try this Instructables guide for making a hummingbird feeder from recycled plastic containers. It uses a pop bottle and a deli container lid, like the ones from grocery store takeout, with milk bottle caps glued on as feeding ports.
Fill the bottle with hummingbird nectar. The International Hummingbird Society suggests mixing one part white sugar with four parts water. Don’t use food coloring, honey, or artificial sweeteners. The red parts of the feeder attract the birds, not the nectar itself.
If you want something sturdier and easier to clean, Birds & Blooms offers instructions for a glass bottle hummingbird feeder that uses copper wire and a commercial feeding tube. This version takes more effort to make but lasts much longer.
7. Glass Soda Bottle Bird Feeder

This is a step up in craft and durability, and a good reason to save that glass Jarritos or Mexican Coke bottle. Birds & Blooms’ glass soda bottle feeder tutorial pairs a recycled glass bottle with a chicken feeder base for a sturdy feeder that holds plenty of seed and will last for years.
The most involved step is drilling a hole in the bottle’s bottom using a diamond drill bit under running water to keep the bit cool so the glass doesn’t crack. A steel rod threads through the bottle and into the chicken feeder base, locked in place with a washer and wing nut; a G-hook at the top completes the hanger. To refill, simply unscrew the base, add seed, and reattach.
This DIY project requires comfort with a drill and patience with glass, but the result looks intentional and well-made, not like a weekend craft project. For the nectar-recipe and feeder-cleaning guidance that applies to all glass bottle builds, the International Hummingbird Society’s feeding page and Birds & Blooms’ black oil sunflower seed guide are solid references depending on what you’re trying to attract.
To find out where to recycle glass bottles in your area, check the Earth911 Recycling Directory. Most curbside programs don’t accept them, but many drop-off sites do.
Tips for Bird Feeders
- Clean your feeders every one or two weeks to stop mold and bacteria from harming birds.
- Hang feeders at least five feet above the ground and away from bushes where cats might hide.
- Black oil sunflower seeds attract the most types of birds.
- For hummingbird feeders, change the nectar every two or three days. In hot weather, change it even more often.
- Plastic feeders break down faster than glass ones in sunlight. Check them regularly and replace when needed.
