Networks of crafters around the world are creating crocheted coral reefs to advocate for climate action (2024)

For craftivists who love to use their passion for fiber arts to do good, there is no holier grail than the Crochet Coral Reef.

The wildly detailed art and geometry project by sisters Christine and Margaret Wertheim uses unwieldy, colorful, hand-stitched coral to respond to climate change and has been brought to life in museums around the world over the past two decades.

It started with what is now called the “Core Collection,” or a mass of crocheted reefs created by the Wertheims that has traveled to the globe’s most esteemed museums and galleries.

But the other strand of the project, which invites thousands of handicrafters to contribute, exists in a poetic contrast to the real-world state of the planet’s reefs; it’s growing rapidly.

“At a time when living reefs are dying from heat exhaustion and our oceans are awash in plastic, the Crochet Coral Reef offers a tender impassioned response,” the project’s website reads.

“This is a crafty retort to climate change, a one-stitch-at-a-time meditation on the Anthropocene.”

Described as the “environmental version of the AIDS quilt,” per the New York Times, the Crochet Coral Reef is a work of grief and action — an attempt to convey the beauty of the natural world, made by the hands of humans.

“Like the organic creatures they emulate, these handmade sculptures take time to make – time that is condensed in the millions of stitches on display, time that is running out for earthly critters,” the website continues.

According to the Wertheims, the project — which has been supported by over 25,000 volunteer crocheters — also speaks to the feminist arm of the environmental movement.

“The Crochet Coral Reef project is a condensation of human labor – particularly female labor – hundreds of thousands of hours of stitching quietly performed,” the artists write.

“Handicrafts have always been aesthetic tools rich in symbolism and expressive possibility, and ‘ladies’ doing their embroideries have long been artists, even if they are rarely acknowledged as such.”

The “reefers” who have contributed their handiworks to the project have responded with zeal to create “satellite reefs.” The biggest community piece, completed in 2022, is a reef at the Museum Frieder Burda in Germany — consisting of over 40,000 coral pieces by 4,000 contributors.

Two other recent satellite projects were completed in 2023 and are still on display in Austria and Pittsburgh.

But the satellite reefs are not limited to the fine art world. Some have been made in science centers, colleges, civic centers — and even women’s prisons and juvenile detention centers.

“Each new site adds further layers of social complexity, extending an experience of art making to citizens in diverse communities and settings,” the website says.

The best part? All contributors are credited in formal exhibitions.

“Just as living reefs are created by the efforts of billions of tiny coral polyps working together, so the Crochet Coral Reef is constructed by communities, thousands of people working together,” the artists explained on their website.

“Every crafter who contributes to the project is free to create new species of crochet reef organisms by changing the pattern of stitches or working with novel materials. What started from simple seeds is now an ever-evolving, artifactual, hand-made ‘tree of life.’”

While these projects can’t necessarily save the earth’s reefs from the devastating impacts of climate change, some include collected plastics from reefs themselves, as well.

Above all, what the Wertheims have accomplished is a deeper understanding of humanity’s connection to the natural world — and its desire to protect it.

“These crochet reefs are time-laden rejoinders to a culture of doom, quietly asserting … a message of hope. What can we humans do when we work together, not ignoring ecological problems?” the artists write.

“By insisting on the value of the hand-made, the Crochet Coral Reef project makes a claim about history and the importance of material labor to prospects for human survival.”

In other words? The project does what all climate movements dream of: bringing people together to do the most important work on the planet — saving it.

“The Crochet Coral Reef has its utopian quality above all in the fact that a positive project emerges from joint work,” reviewer Ann-Katrin Gunzel said of the German satellite reef in 2022. “It shows the beauty and power of collective action.”

FAQs

Networks of crafters around the world are creating crocheted coral reefs to advocate for climate action? ›

The wildly detailed art and geometry project by sisters Christine and Margaret Wertheim uses unwieldy, colorful, hand-stitched coral to respond to climate change and has been brought to life in museums around the world over the past two decades.

How do coral reefs help climate change? ›

The ridged structure of the corals acts as a natural barrier that reduces the energy within waves by up to 97%, thus lowering the impact of Tsunamis and hurricanes globally [4]. Consequently, the impact that the reefs have when reducing the impacts of climate change is immense.

What purpose do the coral reefs serve in our world? ›

Coral reefs hold enormous ecological, economic, and cultural value to hundreds of millions of people around the world, providing valuable ecosystem services, including nutrition, economic security, and protection from natural disasters.

How are coral reefs used as a climate proxy? ›

Coral reefs provide proxy information about rates of sea level change in the past, and individual coral colonies can be used to reconstruct the annual cycle of temperature and salinity variations for up to three centuries.

What are the 5 importances of coral reefs? ›

Benefits of coral reef ecosystems

Coral reefs protect coastlines from storms and erosion, provide jobs for local communities, and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food, income, and protection.

Why is the coral reef dying? ›

Globally, coral reefs have declined by half since the 1950s, largely due to climate change. Indeed, the leading scientific authority on climate change suggests that if the world warms by 1.5 degrees Celsius, relative to pre-industrial times, coral reefs could decline by 70 percent to 90 percent.

How do coral reefs protect the environment? ›

Coral reefs provide a buffer, protecting our coasts from waves, storms, and floods. Corals form barriers to protect the shoreline from waves and storms. The coral reef structure buffers shorelines against waves, storms, and floods, helping to prevent loss of life, property damage, and erosion.

Do coral reefs clean the ocean? ›

Many corals and sponges are filter feeders, meaning they consume particulate matter (pollutants that do not dissolve in water) in the water. This prevents these particles from settling on the bottom of the ocean and dirtying the ocean with harmful materials.

What would happen without coral reefs? ›

If all coral reefs were to die, 25% of marine life would lose their habitat. There are roughly around 1 million different species that rely on coral reefs for food and shelter.

What jobs do coral reefs provide? ›

Healthy coral reefs contribute to fishing and tourism, providing millions of jobs and contributing to economies all over the world. Scientists develop important drugs from coral reef organisms as treatments for cancer, arthritis, and viruses.

How can corals teach us about climate? ›

These seasonal variations in density produce growth rings similar to those in trees. Scientists can study these rings and other characteristics to determine the climate conditions during the seasons in which the coral grew. These growth bands also allow scientists to date coral samples to an exact year and season.

Why are corals so important in climate research? ›

Coral reefs are found in less than 1% of the ocean but are home to nearly one-quarter of all known marine species. They also help regulate the sea's carbon dioxide levels and are a crucial source for scientists searching for new medicines.

What is the largest structure ever made by life on Earth? ›

Satellite photograph of the Great Barrier Reef situated off the northeastern coast of Australia. Stretching for 1,429 miles over an area of approximately 133,000 square miles , the Great Barrier Reef is the largest coral reef system in the world.

What are the two major threats to coral reefs? ›

Increased ocean temperatures and changing ocean chemistry are the greatest global threats to coral reef ecosystems. These threats are caused by warmer atmospheric temperatures and increasing levels of carbon dioxide dissolved in seawater. As atmospheric temperatures rise, so do seawater temperatures.

How do coral reefs impact humans? ›

Half a billion people rely on coral reefs for food and income. But reefs provide more than food. They also provide protection. Healthy reefs protect land from the damaging effects of tropical storms, shielding the shoreline from waves.

What are 3 major benefits coral reefs provide why are they worth saving? ›

In summary, healthy coral reefs provide:

Food: For people living near coral reefs, especially on small islands. Protection: A natural barrier protecting coastal cities, communities and beaches. Medicine: The potential for treatments for many of the world's most prevalent and dangerous illnesses and diseases.

What are coral reefs made of and why are they so important? ›

A coral reef is made of thin layers of calcium carbonate

Coral polyps form a living mat over a calcium carbonate skeleton. Stony corals (or scleractinians) are the corals primarily responsible for laying the foundations of, and building up, reef structures.

Why are coral reefs important and are they in danger? ›

To date, we still have around 74% of our coral reefs left. The continuously growing human population and global warming is threatening our coral reefs – where 25% of marine animals live and where 90% of them rely on for one reason or another. The whole marine ecosystem is being threatened by the loss of our reefs.

Why is saving the coral reefs important? ›

Coral reefs provide coastal protection for communities, habitat for fish, and millions of dollars in recreation and tourism, among other benefits. But corals are also severely threatened by rapidly worsening environmental conditions. Learn how NOAA works to restore these valuable habitats.
