“Not everybody in Alaska is a fisherman. But all of us live on salmon land….If you look at a map of the Kenai Peninsula, it just looks like a cardiovascular system. Salmon are like the heartbeat.”
These words, spoken by a young Alaska fisherwoman named Hannah Heimbuch, open a short documentary the Smithsonian created called The Heartbeat. Featured in the D.C. Environmental Film Festival this March, it tells the story of Alaska’s Kenai Lowlands—one of the few places on Earth where sustainable salmon management remains possible. Click to continue »

It would be tempting say Kallan Benson isn’t your typical teenage student. Homeschooled since preschool age, she has plenty of memories of doing homeschool programs at the Smithsonian Environmental Research Center with her younger brother, Reese.
“We made toothpaste one time,” she recalled. “Reese’s group, him and two of our other friends, their strategy was just put everything in….Every flavor, they just put it all in. No one wanted to taste it.”
But as an organizer for the grassroots climate group Fridays For Future, Kallan is one of thousands. Possibly even tens of thousands. The tidal wave of students striking to demand climate action is gaining momentum, and Benson is among those leading the charge. Click to continue »

A communicator with a passion for environmental and social issues, Christina Arena left her mark on the environmental film world with the 2018 series Let Science Speak. The short documentary videos go beyond the “war on science” headlines to humanize scientists and let them tell their own stories. Today, she’s donating her time and talent to help produce videos for the Smithsonian Environmental Research Center (SERC). Her newest short film will premiere this April at the Smithsonian’s digital Earth Optimism Summit April 22-24. In this Q&A, she talks about what gives her purpose and optimism.Click to continue »
Science comes with some wacky challenges. In the world of marine invasions, that might include sunburns from afternoons tying equipment to docks or worrying about how much seafood powder to feed a plate of invertebrates. But when someone dons a lab coat, they don’t shed their homelife, background, and personal responsibilities. At SERC-West, intern Jessenia Suarez got to know some of those unique challenges while working on her research project. But one of her biggest challenges was outside the lab.
Suarez is a senior marine biology major at San Francisco State University who found her passion for biology in her second year at community college. In summer 2019, she studied how a group of underwater creatures known as the fouling community responds to changes in water temperature. She found the work exciting and refreshing—but she admits that her biggest challenges were balancing the internship with a two-hour commute and finding childcare for her two-year-old daughter, Leia.
“I would spend about an hour and a half with her when I got home, and then it would be time to sleep,” she said. “Not only that, but I was still working my other job [as a CVS pharmacy technician]—very few hours, but it’s still time away from her. It was hard for me, and it was hard for her too.”
Besides caring for her daughter and working a second job, she also had to balance classes. Yet despite a heavier workload than the average intern, Suarez loved the internship experience, and she’s passionate about pursuing research after her degree.
“I had an idea that I liked doing research, but being in charge of my own project brought it to a whole new level, ” Suarez said. “I now know what to expect, and have a feeling that I can handle it.” Click to continue »
If there’s any constant in SERC research fellow Jason Thomas’ diverse career, it’s that he’s always looking for opportunities to learn something new. He’s a science teacher, and that’s one thing that brought him to education: It keeps him in a constant state of learning.
Originally, though, he wanted to be a doctor. After getting a bachelor’s in sociology and a post-baccalaureate in biology, he worked in a molecular lab analyzing octopus eyes, and then in a mosquito hatchery. He then got a medical doctorate—but after having trouble securing a residency, he found himself going back to school for a master’s in teaching.
“Once, someone called me ‘Graduation Jason’ because all I do is graduate,” Thomas joked. Now that he’s a science teacher at Browning High School in Long Beach, California, he’s helping his students graduate with the skills they need to pursue careers in STEM.
Welcome to the Plasticene. If you’re under age 70, it’s possible you’ve lived in the Plasticene for your entire life. It’s a new geologic age some scientists have proposed to mark the near-universal spread of plastic around Earth. Since the 1950s, researchers say, we’ve been living in the Age of Plastics.
You may have heard of another relatively new time period—the Anthropocene, or Epoch of Humans. (Yes, we live in confusing times.) However, the Age of Plastics isn’t meant to replace that. Instead, the Age of Plastics is a smaller piece of the Epoch of Humans that started in the mid-20th century. Scientists contend it deserves special recognition because, unlike many things we leave behind, plastics can leave a distinct mark in the fossil record.
Many strange things have begun appearing in the Age of Plastics, especially in our oceans and along our shores. Some are so new, scientists are just finding words for them. What do you call an animal that makes its home on plastic? How about one that accidentally swallows a bottle cap? For that reason, a team led by Linsey Haram from the Smithsonian Environmental Research Center, Williams College-Mystic Seaport and Hawai’i’s International Pacific Research Center put together a list of terms poised to become more common in the future. Here are 12 words that describe the new age:
Plasticene
The Age of Plastics, a proposed new age in Earth's history that began with the proliferation of plastics in the 1950s. Scientists believe the buildup of plastics will leave traces in the fossil record. The "Plasticene" would fit inside the larger "Anthropocene," or Epoch of Humans. (Credit: Bo Eide.

Plastisphere
Communities of organisms that live on floating plastic. While originally this word referred to only microbes, scientists now propose expanding it to include entire communities associated with plastics, from tiny bacteria to large bivalves and even fish. (Credit: Nancy Treneman)
Epiplastic

Plasticized
Describes environments or animals made more "plastic" by the spread of plastic pollution. "Plasticized animals" are ones that eat plastic inadvertently or get tangled in plastic litter, like this seal. (Credit: Nels Israelson.

Plastivore
An organism that ingests plastic accidentally, often mistaking plastic for one of its natural foods. The Laysan albatross has become a poster-child plastivore: These birds pick up plastic as they search the water's surface for food—food which they often feed to their chicks. While adults can vomit up the plastic, baby chicks can't, so it remains trapped in their stomachs. (Credit: Claire Fackler/NOAA)
Plastiglomerate
A hard material that forms when molten plastic fuses with rock or other materials. This can happen when plastic burns in campfires, especially on beaches. (Credit: Museon. Creative Commons License: Commons License: https://creativecommons.org/licenses/by-sa/4.0/deed.en)
Pyroplastic
A mass of melted plastic debris found on beaches. Unlike plastiglomerates, pyroplastics contain only plastic, making them less dense and able to float in seawater. (Credit: minustide. Creative Commons License: https://creativecommons.org/licenses/by-nc-nd/2.0/)
Plasticrust
Plastic debris attached to a rocky shore. A team of Portuguese scientists led by Ignacio Gestoso coined the term after discovering them on an island in Madeira in 2016. (Credit: Ignacio Gestoso)
Plastitrash
Garbage, litter, debris or other waste made of any kind of plastic. (Credit: KimF. Creative Commons License: https://creativecommons.org/licenses/by-nc/2.0/)
Plastic Confetti
Small, multicolored plastic fragments that form as larger plastic pollution degrades. Though long used in toy and party decoration stores, the term "plastic confetti" first began to describe pollution when it appeared in the Pacific Ocean, according to the paper's authors. (Credit: Annie Crawley)
Plastic Cycle
The origin and movement of plastic between different environments. This includes human environments, such as places that produce or transform plastic. (Credit: Bdx. Creative Commons License: https://creativecommons.org/licenses/by-sa/4.0/deed.en)
Nurdles
Tiny beads or pellets of plastic that act as raw materials for manufacturing plastic products. A word of many faces, "nurdle" has also been thrown around in the sport of cricket and described globs of toothpaste. (Credit: gentlemanrook.

The ocean is losing its breath. Two years ago, an international team of scientists known as GO2NE (the Global Ocean Oxygen Network) published a report in Science with a stark picture of oxygen loss in Earth’s waters: In the open ocean, the amount of water with zero oxygen has spiked fourfold since the mid-20th century. In coastal water bodies, places with dangerously low oxygen (2 milligrams per liter or less) have increased more than 10-fold. It’s a problem not just for animals, but for people and economies—especially those that rely on tourism or subsistence fishing.
On Dec. 7, a new report emerged from the International Union for the Conservation of Nature. The ocean could lose 3-4% of its total oxygen by the end of the century if nothing changes, with losses even higher in the top, biodiversity-rich 1,000 meters. Large fish like tuna, sharks and marlin are among the most vulnerable. In the closing chapter, led by Denise Breitburg of the Smithsonian Environmental Research Center, they created a massive blueprint for resuscitating the ocean.
We’ve pulled out the highlights below, but the key lies in cracking two global conundrums—nutrient pollution and climate change. Nutrient pollution happens when chemicals like nitrogen and phosphorus stream into the water and fertilize massive growths of algae, which suck oxygen out of the water. Climate change’s role is more subtle, but just as powerful: Warmer water can’t hold as much dissolved oxygen. Warm water also doesn’t mix as well, so oxygen from the atmosphere that’s abundant near the ocean surface doesn’t reach everywhere that needs it.
Fortunately, these two problems are linked. Cleaning up nutrient pollution can help solve climate change, and vice-versa—and the ocean will breathe easier for it. Here are eight highlights from the new report: Click to continue »

Every parent wants to give their children the best shot at life. But sometimes, this means more than protecting newborns after birth. Some species can prepare offspring for tough conditions before they enter the world. It’s called transgenerational plasticity. Sarah Donelan, a Smithsonian Environmental Research Center postdoc, has spent years piecing together how it works. This November she published a new article highlighting how humans could be changing this age-old parental strategy. Discover more in the Q&A here.

This article originally appeared in the November issue of the Smithsonian’s Sustainability Matters newsletter.
One small bag that could fit into an office-sized trash can. That’s all the waste that remained after a concert with more than 300 attendees, over 50 staff and volunteers, eight performing groups and four food vendors. Surrounding it, eight recycling containers and four composting bins waited for pickup. By and large, the first Chesapeake Music Festival achieved its goal of near-zero waste, to the exhausted but happy relief of its organizers.
Months of effort went into that lone trash bag: working with vendors, buying supplies, and encouraging the public to bring their own water bottles to cut down on single-use plastics.
