Search crews began immediately looking for pieces of the jet in vast bodies of water such as the Andaman Sea and the South China Sea—and came up empty. What if the answer to finding a piece of the missing aircraft was as simple as not littering the next time you are at the beach? According to a report released this week by the Ocean Conservancy, a nonprofit environmental advocacy group based in Washington, DC, the unfortunate missing plane scenerio highlighted another global problem: our trashed oceans. The report says volunteers retrieved 12 million pounds of trash during last fall’s International Coastal Cleanup, the highest ever in the event’s 28-year history.

The event spanned more than 92 countries with more than 5,000 separate clean-up sites. The trash that was found was staggering. According to the report, the trash collected by nearly 650,000 would fill roughly 38 Olympic-sized pools. The garbage weight was equivalent 823 male African elephants.

“Recently, the tragic loss and subsequent search for the Malaysia Airlines jetliner drew the world’s attention to large pieces of debris floating in the open ocean,” says Nicholas Mallos, Ocean Conservancy’s marine debris specialist and conservation biologist. “Now we have this data that shows the vast array of trash along shorelines and in the coastal ocean—and this is only a small fraction of what’s out there.” Mallos added that the sparkling blue waters you swim in at your favorite tropical resort have the same problems outlined in the report. “Even in those beautiful tropic waters, you will find debris because at the end of the day, we have one ocean,” he says. “It’s truly a global problem.” More From Rodale News: 5 Key Strategies for Living a Plastic-Free Life But is the answer really as simple as not littering the next time you head out to the beach? It’s something to think about as the unofficial start to summer begins, says Mallos. “It doesn’t have to be a complex solution when you’re headed to the beach; there are ways to minimize your impact,” he says. “We’re not saying don’t take your lunch or your drinks with you to the beach, just take everything with you when you leave.” And when you see that stray chip bag or bottle lying in the sand, pick it up, he added. “It could be a small answer to a larger, more global problem,” Mallos adds.
