The Environmental Protection Agency has proposed strict new limits for PFAS “forever” chemicals in drinking water. PFAS are associated with health concerns including cancers and reproductive issues, so the move is being called a huge win for public health.
Also, so-called “chemical recycling” is a greenwashing term used for incinerating plastic according to critics, who say it’s contributing to climate change and poor air quality for many marginalized communities.
And the topography of the coastal seafloor has a lot to do with how much flooding coastal areas will experience during hurricanes. A team of scientists is working on a new technology to create more accurate seafloor maps in the Gulf of Mexico.

2023 was the hottest year on record, at 1.48 degrees Celsius above preindustrial levels. That’s just below the 1.5 C increase that the UN says is the limit to avoid the worst impacts of climate change. As the summer of 2024 approaches in the Northern Hemisphere, climate scientists are raising the alarm on dangerous impacts of ongoing heat waves.
Also Shell’s flagship carbon capture and storage project in Canada generated millions of dollars in carbon credits based on greenhouse gas emission reductions that never took place. According to a study by Greenpeace Canada, the scheme was part of Shell’s billion-dollar Quest carbon capture project. While these phantom credits were legal from 2015 to 2021 under approved carbon tax rules, Shell’s actions raise questions about carbon capture practices in Canada’s lucrative fossil fuel industry.
And a paper published in the journal Scientific Reports describes the case study of an orangutan who treated and healed his own wound. Zoologists have long seen behaviors of self-medicating in the animal kingdom, but until now it has rarely if ever been documented in scientific literature.

To replace the Clean Power plan the Obama Administration failed to get past the courts the EPA published new rules for existing coal plants and new gas power plants that tighten standards for mercury emissions, wastewater, and coal ash and also curb coal plant CO2 emissions over time.
Also how the 2024 Goldman environmental prize winner from Asia mobilized his community to protect the Hasdeo Aranya forests in the state of Chhattisgarh from coal mining. As well as how 2024 Goldman Environmental Prize recipient from North America, Andrea Vidaurre led a campaign that convinced the California Air Resources Board to make rules designed to decrease air pollution and lead to zero-emission trucking by 2036. 
And the fourth meeting of UN talks aimed to address plastic pollution took place this April in Ottawa, Canada. The goal is to have a legally binding international agreement on plastics pollution by the end of 2024.

New Power Plant Rules, Protecting India’s Forests, Fighting Pollution Linked to Online Shopping and Plastic Pollution Treaty Talks

The Biden Administration is helping finance advanced nuclear power reactors and refurbishment of traditional nuclear power stations to promote the generation of zero-emission electricity. Some designs offer more flexibility in power output to an electrical grid where renewable energy is intermittent. 
Also after years congressional battles the EPA is finally banning all uses of asbestos, a highly toxic substance. Maria Doa of the Environmental Defense Fund discusses why it took so long and the anticipated public health benefits of the phaseout.
And despite an international agreement to phase out financing for fossil fuel projects abroad, the Biden administration recently approved a $500 million dollar loan guarantee for an oil and gas drilling project in Bahrain.

On Earth Day President Biden announced the official launch of his new climate-focused jobs program, the American Climate Corps. Special Assistant to the President on Climate Maggie Thomas discusses the thousands of jobs the Corps offers in community outreach, biological surveys, invasive species removal and more.
 Also, small towns in Appalachia are being targeted for so-called chemical recycling plants, but residents are pushing back and citing concerns about chemical fires, air pollution, and toxic wastewater polluting local rivers. Opponents in Point Township, Pennsylvania succeeded in canceling a project there, and we discuss two other proposed chemical recycling plants in Ohio and West Virginia.
And lithium is used in electric vehicle batteries and plays a key role in the global shift towards clean transportation, but current extraction methods come with environmental costs. Some companies are exploring an alternative that taps brine water deep in the Earth. We explore how it works and what questions about its impacts remain.

Our Earth Day special examines this decisive moment for the human species and our challenging relationship with our planet.
We meet people who envision a future reshaped by an emerging energy system and new power structures, as we wean off of fossil fuels.
Next we take a big-picture view of Earth as a complex and sustaining organism known as Gaia. Over billions of years life has interacted with the elements of this planet in cycles of constant change and adaptation. With the help of deep ecologists, children, an astronaut and more, we survey our place on this ever-evolving living planet.
And while science and policy are vital in building a more sustainable world, they can't convey the values we need as we strive for ecological harmony. Indigenous stories, holy scriptures, East Asian cosmologies, papal encyclicals and divine revelation all shed light on our duties and relationship to each other and to our common home.
