The researchers of this article had a hypothesis that the vast majority of new agricultural land was coming at the expense of disturbed forest and natural tropical forest land. This is land that has not before been cleared and is apart of our growing scarcity of natural forest and wildlife. They used satellite taken pictures to examine and cover map projections of the newly cleared land for agriculture. A map depicting some of the increased clearing for the agriculture can be seen below :
In conclusion of the research they learned that 80% of new land for agriculture was coming from intact and disturbed forest. Combined with the fact that food needs are expected to grow ~50% by 2050, this puts our Earth's natural forestry at risk to be completely cleared to make room for more food to be harvested. Work like this helps shed light on the rising risk of losing some of the Earth's natural ecosystem which we use to survive. I wonder if work like this continues to be done, if it will begin to shed light on a growing problem before it is too late.
