Federal investigators say they have "significant safety concerns" about a Ford SUV recall repair that doesn't fix gasoline leaks that can cause engine fires. The U.S. National Highway Traffic Safety Administration is demanding volumes of information from the automaker as it investigates the fix in a March 8 recall of nearly 43,000 Bronco Sport and Escape SUVs with 1.5-liter engines. Ford says the SUVs have fuel injectors that will crack, allowing gas or vapor to leak near hot engine parts that can cause fires. But the agency says the recall fix does not proactively replace fuel injectors before they fail.

Thousands of negotiators and observers representing most of the world's nations are gathering in the Canadian city of Ottawa this week to craft a treaty to end the rapidly escalating problem of plastic pollution. Each day, the equivalent of 2,000 garbage trucks full of plastic are dumped into the world's oceans, rivers and lakes. People are increasingly breathing, eating and drinking tiny particles of plastic. Some at the talks thinks there should be less plastic produced. Oil and gas companies and some countries rich in these resources disagree. Most plastic is made from fossil fuels. Inger Andersen, at the UN, says it's a once-in-a-lifetime opportunity to fix something everyone knows must be fixed.

Dozens of the children of Flint's lead-contaminated water crisis have turned their trauma into advocacy 10 years after it began. Now as teenagers and young adults, they're providing input on public health initiatives, campaigning for social issues, distributing filters and providing free water testing for homeowners. The crisis was set in motion April 25, 2014, when the city of Flint halted the flow of water supplied by Detroit for decades. Flint stills struggles with issues like population loss, poverty and school achievement. But young activists say they hope to make a difference — and defy expectations.

Marijuana advocates are gearing up for April 20. Known as 4/20, marijuana's high holiday on Saturday is often marked by large crowds gathering in parks, at festivals and on college campuses to smoke together. This year activists can reflect on how far the legalization movement has come. Medical marijuana is now legal in 38 states. Of those, 24 also allow recreational use. Additionally, the Biden administration has shown an openness to marijuana reform. Biden has pardoned thousands of people with federal "simple possession" convictions. The Department of Health and Human Services has recommended marijuana be reclassified as a lower-schedule drug, which would affirm its medical use under federal law.
