I was familiar with Honduras and Nicaragua in the 1980-90s through my Army associations. One of my compatriots was in Honduras in 1986 and 1996. In that 10 year span he watched the same camp go from jungle to arid biome. He traveled into the country and saw the same thing in other areas he was familiar with and was shocked at how denuded and arid the land had become. That was 20 years ago. It has spread since.
