Agriculture does not emit much CO<sub>2</sub> but does emit large quantities of methane (from cattle and rice paddies) and nitrous oxide (from | |||
fertilizers). In all, agriculture accounts for 25% of GHGs if we include the induced deforestation. | |||

* [[En-en adult card 5 fossil fuels|Fossil fuels]] Agriculture does not use much fossil fuel, just enough to keep tractors running. Its carbon emissions are high, bu mainly because of methane and nitrous oxide. | |||
* [[En-en adult card 7 co2 emissions|CO2 emissions]] Agriculture does not emit much CO2 except from deforestation. Its carbon emissions mainly come from othe GHGs. | |||
* [[En-en adult card 10 aerosols|Aerosols]] Spraying crops does result in aerosols and air pollution, but not to the same extent as incomplete combustion from power plants. | |||
* [[En-en adult card 12 carbon sinks|Carbon Sinks]] It doesn't matter if this link is not made, but it is true that agriculture can improve storage capacity through photosynthesis. This is the 0.4% principle (if we increased the soil's capacity to sequester carbon by even 0,4%, we would have a significant impact on CO<sub>2</sub>). | * [[En-en adult card 12 carbon sinks|Carbon Sinks]] It doesn't matter if this link is not made, but it is true that agriculture can improve storage capacity through photosynthesis.

*[[En-en adult card 25 terrestrial biodiversity|Terrestrial Biodiversity]] Here, we are thinking mainly of pesticides (especially Roundup or neonicotinoids).
