"Argentina is the second largest country in South America. It is also one of the 25 most biodiverse country in the world. Argentina is home to several types of indigenous forests. Nevertheless, the rate at which these forests are being deforested is alarming. In the start of the 20th century, Argentina had 100 million hectares of forests but now it has reduced to 20 million hectares half of which are still being degraded. The major cause of deforestation in Argentina is logging by foreign and national companies, transportation projects, and establishment of pulpwood and carbon-silk monoculture tree plantation."
