The article titled "Illegal logging takes big toll on Mexico City's crucial forests" published on NBC News, uncovers the devastating impact of illegal logging on the forest-covered southern half of Mexico City. The forests, which recharge aquifers supplying nearly 20 million people and help clean the city's polluted air, have been severely depleted. Alfredo Gutiérrez, a local resident, laments that the forest has been "finished off". The article suggests that organised crime gangs may have moved into the illegal logging business, possibly due to the federal government's crackdown on the sale of contraband gasoline and diesel. In response, Mexico City authorities have identified criminal groups behind illegal logging and have mounted operations involving hundreds of police officers and soldiers who raided clandestine sawmills in the mountains.
