Flying over Amazonia in Bolivia. Areas of thick forest like this are less and less common. In neighboring Peru, the rainforest became a net carbon dioxide emitter rather than carbon sink for the first time in 2012, as deforestation released tree-trapped CO2 into the atmosphere.
A friend in Bolivia sent me into the jungle for a few weeks to volunteer with some nuns he knew who he said were doing health education work–teaching people about sanitation, boiling water, etc. I took a plane across Bolivia into the provincial capital of Trinidad, then another flight on a Cessna six-seater with no seatbelts to arrive at Bella Vista. The nuns greeted me warmly but it turns out they weren’t doing health education at all (and for their part, they thought I was going to be a doctor!) I ended up teaching English and chess at the boarding school the nuns run. Miss these kids.
