The critically endangered Lake Titicaca water frog inhabits Lake Titicaca in the Andes, at elevations over 12,500 feet. This amphibian thrives in its high-altitude, cold, low-oxygen environment thanks to voluminous skin folds, earning it the nickname "scrotum frog." These folds increase surface area, allowing efficient oxygen absorption.

Despite its unique adaptation, the frog faces severe threats. Its population declined by an estimated 80 percent between 1990 and 2004, primarily due to human predation and water pollution. This alarming drop underscores its critically endangered status.

Not all "vampires" reside in Transylvania; some infest underwater pens of farmed salmon. Tiny parasites called sea lice make life miserable for both farmed and wild fish, weakening adults and killing juveniles.

These bloodsuckers pose a dual threat: the lice themselves harm fish, and the pesticides used to control them can be toxic to other marine life. Their prevalence signals a critical need for improved practices in certain salmon farms.

Poke, a popular raw tuna dish, raises significant sustainability concerns. Tracking the origin of yellowfin or bigeye tuna used in poke is often difficult, highlighting broader issues in the seafood supply chain.

This lack of transparency is common across the seafood industry, leaving consumers with little information about what they eat. To combat seafood fraud and promote sustainable practices, Oceana is actively working on solutions. Learn more about their efforts: https://bit.ly/2FvJLZo

Racism denies humanity, sexism demeans, and their intersection limits true freedom. Frances Cudjoe-Waters, a Black woman and Harvard Law alumna, realized the exhaustion of politely presenting her pain to predominantly white audiences. She decided to abandon polite conversation and speak her truth, declaring, "I Ain't Sorry." She never expected to witness the reemergence of civil rights issues like Charlottesville and repeated acquittals for killings of Black individuals, reminiscent of the 1960s. While seeking to facilitate discussions, she recognized the toll of maintaining dispassionate intellectualism. Her family was featured in the Dallas Morning News.
