Satellite image of thick smoke in Borneo from numerous fires, most of them likely started by the "slash-and-burn" technique of local deforestation for agriculture, though logging activities may have started the fires accidentally. The exceptionally heavy smoke is caused by the burning of the peat in the peat swamp forests of the area and it results in air pollution, disrupts air traffic, and significantly adds to greenhouse gas emissions.

An artist's rendition of an Allosaurus fragilis with its jaws open fully, based on the research of paleontologist Robert T. Bakker. Allosaurus were active predators of large animals, and probably had the ability to open their jaws extremely wide. Studies suggest that they attacked prey open-mouthed, slashing flesh with their teeth, and tearing it away without splintering bones. Allosaurus was a genus of theropod dinosaurs that lived in the upper Jurassic period. Image: Steveoc 86
