In 2008, fifth-grader Cassandra Lin founded Turn Grease Into Fuel (TGIF) after learning used cooking oil could be converted into affordable, clean-burning biodiesel for home heating. TGIF partners with local restaurants to collect kitchen grease, which is then recycled and distributed to charities assisting families with heating needs. This initiative has already helped offset over two million pounds of carbon dioxide emissions.

Lin and her team further championed environmental efforts by drafting Rhode Island's Used Cooking Oil Recycling Act in 2011. Passed into law in 2012, this legislation expanded TGIF's reach, establishing a robust network that effectively addresses community needs while significantly reducing waste and pollution.

David Wallace-Wells observes that few Silicon Valley titans are addressing climate change, despite the opportunity to leave a significant legacy. He points to Bill Gates-funded negative emissions technology, which could enable current industrial activity without global warming.

This technology would cost $3 trillion annually to operate worldwide. While substantial, this figure is less than the $5 trillion spent each year on global fossil fuel subsidies.

The U.S. House of Representatives has passed bipartisan legislation to ban the domestic shark fin trade. This action addresses shark finning, a cruel practice where fins are removed at sea and the shark's body is discarded. While finning is illegal in U.S. waters, fins are still traded, often imported from countries with inadequate protections.

The global shark fin trade is a primary driver of declining shark populations worldwide, impacting an estimated 73 million sharks annually. This unsustainable demand has led to over 90% declines in some populations, threatening one-third of species in major trade hubs with extinction. The U.S. ban aims to mitigate this devastating impact.
