  • Plastic pollution continues to wreak havoc on the planet. It can be found everywhere on Earth, from the highest mountain peaks to the deepest parts of the ocean. According to the National Resources Defense Council, nearly ten billion tons of plastic have been produced since the 1950s, with more than half created in just the past 25 years.
  • The sources of U.S. electricity production have changed dramatically over the past 15 years and continue to change as the political winds blow in different directions.
  • A coalition of 24 states as well as a dozen cities and counties has sued the Trump administration over its decision to relinquish the government’s legal authority to fight climate change. The lawsuit is likely to be consolidated with a case that 18 environmental, healthcare, and scientific groups already filed in February.
  • The Trump administration is pushing to scale up oil and gas production in the US, despite heavy criticism and environmental concerns. It is urging the establishment of an 11th National Outer Continental Shelf Leasing Program to open up areas in Alaska, California, and the Eastern Gulf of Mexico. The Interior Department is advancing a new 5-year leasing program to increase oil and gas development, reversing prior restrictions.
  • Last year, Congress eliminated the federal tax credit that made electric cars more affordable. As a result, enthusiasm for and interest in electric cars diminished. But the war in Iran has resulted in soaring gasoline prices and suddenly electric cars seem more attractive again.
  • There are vibrations occurring in the ground nearly all the time. They happen when cars pass by, when machines are operating, and from natural forces in the earth’s crust. For the most part, we don’t notice these vibrations. But they are there, and they represent an untapped source of clean energy.
  • As warmer spring temperatures spread across much of the country, people and pets are spending more time outdoors, and fleas and ticks are becoming active again. Many pet owners rely on flea and tick treatments to keep their animals protected, but new research suggests that some of these medications may have unintended consequences.
  • Utility-scale solar power is the fastest-growing source of electricity in the U.S. Well over half of all new U.S. electric capacity added in 2025 was utility-scale solar. As of late 2025, total utility-scale solar capacity surpassed 153 GW, enough to power 45 million homes.
  • Since the 1950s, Madagascar has lost over 27,000 square miles of forest – more than half of its natural forest cover. The decimation of the forests has been the result of small-scale agriculture, illegal logging for fuelwood and charcoal extraction, and from uncontrolled fires.
  • The world is moving towards the electrification of vehicles. In 2025, EVs grew by 33% in Europe and 20% worldwide. They represented 50% of new car sales in China. It’s a very different story in the United States, where EV sales actually fell by 4% year-over-year.
