Land use change is still a major source of carbon dynamics emission due to burning and cultivation, which caused to decline soil organic carbon contents in soils and degrade soil quality.

因烧垦而引起的土地利用变化仍然是碳素释放的主要来源，从而导致了土壤有机碳含量下降和土壤质量退化。

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).
