Sixty percent of all anthropogenic N2O emissions are from agriculture. The list of human and animal victims of the Australia wildfires keeps growing – one species might already have gone extinct – as the smoke even reaches South America. Furthermore, pesticides can kill beneficial insects, soil microorganisms, birds and some rare small species like butterflies which have far-reaching effects on biodiversity. When she is not writing, she loves watching sci-fi movies on Netflix. It is also linked to increased incidence of paralytic shellfish poisoning in humans, leading to death. 5 0 obj These changes to the climate are a direct result of changes to natural moisture levels in the surrounding atmosphere.

While global agriculture faces a number of challenges, the most surprising challenge to food security may come from agriculture’s impact on our climate. 7 0 obj It’s time to change the way agriculture affects the environment, and vice versa. Conventional farming uses about 70% of our fresh water supply. The fertilizers, pesticides, manure, herbicides and other agrochemicals have given rise to widespread contamination of waterways and ground waters, in turn affecting plants, wildlife, humans, and animals. Like fresh water, our oceans are also being contaminated. Most of the land on Earth that’s suitable for agriculture has already been converted to fields or pasture. Emissions from agriculture and deforestation are three times greater than emissions from the global building sector, and equal to all industrial emissions. Since agricultural pollution mainly impacts water systems and ground water, aquatic life forms are severely affected.

Dominant sources of agricultural greenhouse gases (GHGs) include carbon dioxide (CO 2) from tropical deforestation, methane (CH 4) from livestock and rice production, and nitrous oxide (N 2 O) from … Volatilization, also called vapor drift, is caused when a pesticide turns into a gas or vapor after spraying. Agricultural emissions from deforestation, while still very large, have dipped slightly over the period, and comprise a smaller share of total emissions over time.

In addition, saltwater makes its way from the ocean into estuaries in increased amounts, which significantly changes the ecosystem and habitat of these waterways as well. It’s rather simple, especially when you talk to organic farmers and realize that bees who feed exclusively on organic flowers are thriving.

The result: Globally, about a third of agriculture’s methane emissions come from livestock. Gerber, James S., Kimberly M. Carlson, David Makowski, Nathaniel D.
