These Floating Sea Trees Could Bring Wildlife Back to Big Cities

These Floating Sea Trees Could Bring Wildlife Back to Big Cities
In the world’s biggest cities, it’s hard enough for humans to find a little elbow room—now think about carving out habitat for wildlife in places like Manhattan. Dutch architect Koen Olthuis thinks he has the design that can extend urban sprawl into city waterways—but instead of floating high-rises offshore, he envisions wildlife oases within city limits. Called Sea Trees, the steel structures are based on existing offshore oil platforms. Anchored to the ocean or river floor, Sea Tree pillars would extend above and below the water surface, providing “layered” habitats—almost like the floors of a skyscraper—for flora and fauna. “Oil companies have used these floating storage towers for years, we only gave them a new shape and function,” Olthuis said in a statement. Olthuis, head architect at Waterstudio, thinks Sea Trees could bring animals back to areas taken over by humans, helping to stem falling wildlife populations. Olthuis designed Sea Trees to be inaccessible to humans.

How to Stop Humans From Filling the World With Trash When the $20 billion Hudson Yards development is finished on Manhattan’s Far West Side in 2024, it will have six skyscrapers, 5,000 apartments, more than 100 stores, and a public school. One thing it will not have is municipal garbage trucks. Related Companies, one of the developers working on the project, plans to install pneumatic tubes that will whisk trash to a sorting area. Are We Missing the Big Picture on Climate Change? Photo The human hands in blue medical gloves spread out the swallow’s wings. The brown feathers jut out like spikes, their tips frizzled and scorched. These wings are no longer graceful fans capable of cupping and pushing off against the air. The left one is worse than the right, and the tail is a pitiful cluster of sticks.

The Surprising Source of Pollution Trashing San Diego’s Beaches When San Diego environmentalists tallied up how much trash they collected from local beaches in 2014, they found, not surprisingly, a lot of plastic. In fact, volunteers removed 23,477 pieces of plastic and 17,438 pieces of plastic foam. But that pollution was dwarfed by the 75,069 cigarette butts fouling beaches, according to a report released Monday by San Diego Coastkeeper and the San Diego chapter of the Surfrider Foundation. “Littered butts continue to be a major concern because they are nonbiodegradable and leach toxins into the water, poisoning marine life,” the report states. “They also move with ease through our storm water systems, meaning a cigarette butt need not be dropped directly at the beach in order to find its way there.”

Seattle 2030 District Releases New Strategic Plan High Performance Building Districts At our Summer Reception, the Seattle 2030 District unveiled a new Strategic Plan to make substantial progress toward achieving our ambitious energy efficiency, water and commuting goals for existing and new buildings. The Board has adopted two strategic priority areas – transforming our buildings and transforming our market. In the built environment, priorities focus on facilitating innovative, pragmatic and economically viable measures that reduce environmental impacts, increase resilience, lower operating costs, and improve property values. These measures expand upon existing efforts such as the Smart Building Initiative and Electrify Seattle as well as introduce new projects such as the Green Stormwater Initiative. In order to create a favorable business and regulatory environment, the Plan details the Seattle 2030 District's approach to informing and advocating for market-based solutions and public policies.

Zero Counties in the U.S. Have Enough Housing for Families in Extreme Poverty From Portland, Oregon, to Portland, Maine. From Jacksonville to Juneau. No matter where you look, there isn’t enough affordable housing. The Case for Mandatory Composting By Aubin Tyler Living in the country, I have the luxury of a backyard compost pile. Right now it’s overflowing with acrid slop, but eventually it will yield dark, rich soil nutrients for the garden. If my potato peels, leftover rice, and parsley stems had been buried in a landfill, deprived of sun or air, those same scraps would have given rise to methane, a potent greenhouse gas that contributes to global warming. Nationwide, there’s a lot of potential in all that slop. In 2008, Americans generated nearly 32 million tons of food waste, and less than 3 percent of that was composted, according to the US Environmental Protection Agency.

This Reusable Paper Saves Trees and Prints Using Ultraviolet Light Scientists are redefining what it means to go paperless. Researchers at the University of California, Riverside, have been working on an alternative to traditional paper that can be printed on and erased more than 20 times. Its low-cost production could help reduce waste, deforestation, and chemical pollution, according to chemistry professor Yadong Yin, who copublished a paper on the design in Nature. “If we are comparing the rewritable paper to conventional ones, it has the advantages of being more economical, environmental, and energy friendly,” he said. “It can be produced at about the same cost as regular paper and does not require additional inks for printing.” Ultraviolet light is used to print on the rewritable “paper,” which is a thin plastic film coated in nontoxic dye.
