Logging roads trigger debris avalanches that accelerate erosion 25 to 340 times more than intact forests
Trees use CO2, converting it into oxygen for other organisms to breathe. Deforestation leads to higher CO2 levels, which directly contribute to global warming.
Due to the color of the sediment runoff in Madagascar, many have commented on aerial photography, like this one, by saying that it appears as though the country itself is bleeding. In a way, that is exactly what is happening.
“The rapidity at which this country is being stripped of its forests must alarm everything thinking man…It is high time that we should turn our earnest attention to this subject which so seriously concerns our national prosperity”-U.S. Secretary of the Interior Carl Shurz, 1877
