<em>While rain forests are critically important to humanity, they are rapidly being destroyed by human activities. The biggest cause of deforestation is conversion of forest land for agriculture. In the past subsistence agriculture was the primary driver of rain forest conversion, but today industrial agriculture — especially mono-culture and livestock production — is the dominant driver of rain forest loss worldwide. Logging is the biggest cause of forest degradation and usually proceeds deforestation for agriculture.</em>
Burning fossil fuels moves carbon from the geosphere to the atmosphere.
Explanation:
A carbon cycle is a model that indicates how carbon is cycled across the spheres of the earth. Burning of fossil fuels is part of this cycle indicating movement of carbon from the geosphere – since fossil fuels are derived from the geosphere (the rocks of the crust) - to the atmosphere as carbon dioxide. Again this carbon will cross over to the biosphere when taken up by plants from the atmosphere during photosynthesis
