As well as destroying such native ecosystems, deforestation also diminishes so-called "carbon sinks" -- thereby reducing the Earth's capacity to absorb and re-process atmospheric carbon dioxide -- while also adding to air pollution through the burning of land to clear it for cultivation (sugarcane fields are traditionally fired prior to harvest to remove leaves and drive away snakes).
