10. Agriculture 
Studies have shown that the global food system is responsible for up to one-third of all human-caused greenhouse gas emissions, of which 30% comes from livestock and fisheries. Crop production releases greenhouse gases such as nitrous oxide through the use of fertilisers.

60% of the world’s agricultural area is dedicated to cattle ranching, although it only makes up 24% of global meat consumption.

Agriculture not only covers a vast amount of land, but it also consumes a vast amount of freshwater, another one of the biggest environmental problems on this list. While arable lands and grazing pastures cover one-third of Earth’s land surfaces, they consume three-quarters of the world’s limited freshwater resources.

Scientists and environmentalists have continuously warned that we need to rethink our current food system; switching to a more plant-based diet would dramatically reduce the carbon footprint of the conventional agriculture industry.
