Without a doubt, the Panama Canal is one of the most notable engineering projects in the world. Through a length of 82 kilometers, this artificial waterway connects the Atlantic and Pacific oceans using a locks system.
“But deforestation threatens more than the tourist dollar or endangered species. Each time a ship passes through the canal, 52m gallons of freshwater – enough for a day’s supply for a small city – is discharged from the locks into the ocean. This water comes from the canal’s watershed, and if that is denuded of trees, it comes laden with silt and in unpredictable surges. The silt raises the bottom of the manmade lakes designed as storage for the canal, critically reducing their capacity.” Source.
