Deforestation—clearing forests for agriculture (e.g., cattle ranching, soy), logging, mining, and urban development—is the primary driver of the large loss of tropical rainforest acreage. Volcanic activity and solar eclipses are not major causes, and temperature changes alone do not explain the scale of the observed deforestation.
