I will start off by saying that this was written by a journalist not a scientist. For this reason, I would take the sensationalist tone with a grain of salt. However, the author also appears to have interviewed villagers, gatherers of various species of sea life within the mangrove estuaries, and scientists from multiple disciplines, so it is, if nothing else, well researched.
It shocked me how important these trees are and how widespread mangroves really are. I had no idea how many species there are. I knew that shrimp farms really do a number on our environment, but I thought it was due to nutrient dumping and not deforestation.
I'm glad that I know a little more about the anthropogenic impact of estuary destruction and plan to do more research on what I can do to help prevent the destruction of these forests and buy my food more responsibly.
