The Colombian army is claiming in a recent report that leftist guerrillas, far-right paramilitaries, and the illegal drug trade are causing ecological disasters within the country. The army says that pipelines blown up by leftists have caused more than 2 million tons of crude oil to pollute 1,625 miles of river in the last 10 years, and that the drug trade has contributed to deforestation and contaminated soil with 200,000 tons of chemicals a year. Overall, the army says that 3,600 square miles of jungle and agricultural land have been lost in the last decade.
