Elizabeth Sherr had always had a passion for the ocean since she was young so trying to clean up the trash that litters beaches and the sea seemed a natural move. When she moved to live next to the sea in Barcelona, the native New Yorker posted some videos on TikTok encouraging others to help rid the beach of cigarette butts and plastic bottles but did not hold out much hope it would catch on. This undated handout photograph released on Jan. 14, 2021 by the University of Barcelona shows an underwater view of a Posidonia Oceanica seagrass meadow in the Mediterranean Sea.

People on TikTok thought it was very funny.  That was the video which went viral with 1.3 million views,” said Sherr, who works for a nonprofit organization that works to combat deforestation.   “I never imagined it would take off like this. It has taken me aback but it has been good. I have always loved the ocean. It has always been my passion.” The European Commission’s directive will oblige all 27 member states to ban the use of plates, glasses and paper packaging covered with a single-use plastic film from July 3. Opposition The measure has met with opposition from some countries like Italy, which produces large quantities of these products. Frederique Ries, the European Parliament lawmaker who led the campaign to ban single-use plastics across the bloc, recently told an Instagram conference on trashchallenge:  “There were people who were hard to convince but we brought them on board for the ban on single-use plastics.” FILE – French skipper Catherine Chabaud stands on her boat as visitors pass by at Les Sables D’Olonne harbor on France’s Atlantic coast on Nov. 2, 2000.Catherine Chabaud, the first woman to travel solo around the world by boat, is a European Parliament lawmaker who has compiled a report on how to combat single-use plastics. “We must strengthen knowledge of nano-plastics, integrate the land-sea link as 80% of pollution in the seas comes from the land and we must launch an action plan to collect litter in rivers and estuaries,” Chabaud told an Instagram conference about #trashchallenge.   Holding a masters graduate in marine conservation, Sherr was inspired by the pioneering marine biologists Jacques Cousteau and Sylvie Earle. FILE – Captain Jacques Yves Cousteau poses on the French Riviera, April 9, 1995.She said Cousteau’s book “Silent World” and Earle’s “Sea Challenge” put her on the path to trying to save the oceans. “Cousteau opened my eyes but I would say that Dr. Earle was my real inspiration,” Sherr said. Earle was the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration. Cousteau, who died in 1997 at 87, was a former French naval officer who wrote a series of influential books and films about marine conservation, the most notable being “The Silent World.”Carolina Sevilla, founder of the conservation group 5 Minute Beach Clean-Up was also involved in the European Parliament’s #trashchallenge. She said that her country, Costa Rica, hopes to become the first in the world where cleaning up the ocean will be part of the educational curriculum for 7 to 11-year-olds.   “We really hope that Costa Rica will become the first in the world mandatory program for students about cleaning up the ocean,” she said.
