For 45 years, the Marine Mammal Protection Act (MMPA) has provided vital protections for dolphins, whales, and seals in U.S. waters.

Unfortunately, a new congressional bill threatens these safeguards. It would facilitate harmful activities like seismic airgun blasting—a loud, dangerous process used for oil and gas exploration—making it easier to injure these iconic animals.

Doorae Shin fell in love with Hawai‘i's majestic landscapes as a freshman on O‘ahu, but was dismayed by Styrofoam litter and its devastating impact on marine ecosystems. In fall 2012, she partnered with the Surfrider Foundation to lead a student petition, gathering 1,000 signatures. This effort successfully prompted the University of Hawai‘i Mānoa to ban single-use foam packaging from all campus dining locations.

Following this campus victory, Shin spent two years advocating for a statewide Styrofoam ban. When that initiative failed, she joined efforts for a county-wide ban on O‘ahu. Shin will soon begin her role as the University of Hawai‘i system's first student sustainability coordinator.

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.

Inspired by a 2004 Wall Street Journal article on the E-Waste crisis, Alex launched Project WIN '05 with his Westerly Innovations Network team. This initiative achieved significant local impact, collecting 21,000 pounds of E-Waste and establishing a permanent town receptacle that has gathered over 60,000 pounds. Project WIN '05 also helped enact local and statewide E-Waste dumping bans.

Alex further integrated computer refurbishing into his school's curriculum, restoring and distributing 260 computers to students locally and in Sri Lanka and Mexico. His recent work includes building an Internet café in Cameroon, developing a UN Environment Program pilot for international youth, and launching a "Bridging Divides" program with U.S. businesses and schools.

Imagine living beside the world's largest freshwater body, yet being unable to afford its use. This is the reality for Highland Park, Michigan residents, who face soaring water costs and demand accountability for these rising expenses.

This critical situation highlights issues of water access, community rights, sustainability, and civil rights, with particular relevance to women's rights, government responsibility, and local activism in Michigan. The topic is explored in a film by Liz Miller.
