A friend of mine, who owns property in San Diego, enlightened me on an ongoing environmental and public health crisis along the southernmost coast of California. Each year, 10 billion gallons of raw sewage (residential and industrial) enters the Pacific Ocean via the Tijuana River. A known and increasing problem for almost a Century, this pollution has not been significantly addressed by either the Mexican or U.S. Governments.
Spreading northward along the Imperial and Coronado Beaches, the marine pollution poses a health threat to humans and wildlife alike; indeed, these scenic beaches are now officially closed most of the time due to hazardous levels of bacteria in the water. Though not documented, one can imagine that industrial chemicals also pose a threat, contaminating the water, sand and air.
When we learn that neighboring Governments cannot cooperate to remedy a local, fixable disaster, it is hard to imagine that humans can adequately address global crises such as climate change. For a concise overview of this tragic scenario, including its medical, environmental and economic consequences, watch The Big Dump documentary on YouTube.
