In this episode: A story about trash and dirt flowing from one side of the U.S.-Mexico border to the other, and two guys’ plan to stop it. The state of California spends $1.8 million annually on a system that keeps trash and dirt from clogging up the estuary in Border Field State Park, a park that butts up against the U.S.-Mexico border fence. The agency that takes care of the park, the Tijuana River National Estuarine Research Reserve, says the system has stopped approximately 2 million pounds of debris from entering the environmentally sensitive estuary. But the trash just keeps coming and coming, pouring through a culvert under the border that's connected to polluted canyons in Tijuana. And perpetually managing the pricey problem instead of actually solving the problem seems like the forever plan. That is, unless Steven Wright and Waylon Matson’s idea gets funded. The environmentalists want to use re-purposed trash from the canyon to build retaining walls and other structures in Tijuana's Los Laureles canyon that would prevent the trash and dirt from reaching the U.S. in the first place.
