What if the children go to schools unafraid of tear gas and bullets?
What if the birds come back, and the bees are healed, and every species moves from endangered, to threatened, to thriving?
What if the rainforest ADVANCES?
What if every parking lot had solar panels? What if every structure had solar panels? What if we built climbing gyms and terraced gardens in the skeletons of old coal power plants?
What if you baked your neighbor bread, and they shared their home-grown blackberries?
What if every person who needed a home, had one? What if every person who needed healing was healed?
What if every body was treasured for what it was, not what it should be?
What if every trans child's parents attended their graduation, their wedding, their new-name-day?
What if every warehouse became a closed-circle repair station? Goods flowing out, and back, and out again? What if landfills started to SHRINK?
What if the water and air were clean? What if there was enough public transit that the cars dwindled, leaving the streets safe for kids on bikes, evening deer, midnight cats and foxes?

These pescatarian birds are directly exposed to PFAS contamination due to the island's position near the St. Lawrence Seaway.
Over fifty years of data show a peak in PFAS (also known as "forever chemicals") content in seabird eggs in the 90s, followed by a decrease as regulations went into effect. The most recent findings show a 70% decrease of most common PFAS.
While continued vigilance a regulation is needed, this data indicates that regulations are working to reduce PFAS concentrations in marine ecosystems.

The slimy strings from okra and the gel from fenugreek seeds can trap microplastics better than the slightly-toxic synthetic polymer in use.
"The substances behind the slimy strings from okra and the gel from fenugreek seeds could trap microplastics better than a commonly used synthetic polymer.
Texas researchers proposed in 2022 using these sticky natural polymers to clean up water. Now, they’ve found that okra and/or fenugreek extracts attracted and removed up to 90% of microplastics from ocean water, freshwater, and groundwater.
With funding from the U.S. Department of Energy, Rajani Srinivasan and colleagues at Tarleton State University found that the plant-based polymers from okra, fenugreek, and tamarind stick to microplastics, clumping together and sinking for easy separation from water.
In this next stage of the research, they have optimized the process for okra and fenugreek extracts and tested results in a variety of types of water.
To extract the sticky plant polymers, the team soaked sliced okra pods and blended fenugreek seeds in separate containers of water overnight. Then, researchers removed the dissolved extracts from each solution and dried them into powders.
Analyses published in the American Chemical Society journal showed that the powdered extracts contained polysaccharides, which are natural polymers. Initial tests in pure water spiked with microplastics showed that:
One gram of either powder in a quart (one liter) of water trapped microplastics the most effectively.
Dried okra and fenugreek extracts removed 67% and 93%, respectively, of the plastic in an hour.
A mixture of equal parts okra and fenugreek powder reached maximum removal efficiency (70%) within 30 minutes.
The natural polymers performed significantly better than the synthetic, commercially available polyacrylamide polymer used in wastewater treatment.
Then the researchers tested the plant extracts on real microplastic-polluted water. They collected samples from waterbodies around Texas and brought them to the lab. The plant extract removal efficiency changed depending on the original water source.
Okra worked best in ocean water (80%), fenugreek in groundwater (80-90%), and the 1:1 combination of okra and fenugreek in freshwater (77%).
The researchers hypothesize that the natural polymers had different efficiencies because each water sample had different types, sizes and shapes of microplastics.
Polyacrylamide, which is currently used to remove contaminants during wastewater treatment, has low toxicity, but its precursor acrylamide is considered toxic. Okra and fenugreek extracts could serve as biodegradable and nontoxic alternatives.
“Utilizing these plant-based extracts in water treatment will remove microplastics and other pollutants without introducing additional toxic substances to the treated water,” said Srinivasan in a media release, “thus reducing long-term health risks to the population.”
She had previously studied the use of food-grade plant extracts as non-toxic flocculants to remove textile-based pollutants from wastewater and thought, ‘Why not try microplastics?’"
