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. | |||

Since then, the impact of human activity on its environment has been growing. Plant species have been domesticated (today, domesticated rice is no longer able to reproduce without human intervention), forests have been cleared to expand cultivated areas, depriving animal species of their natural habitat, and since the Green Revolution (green for agricultural, not for ecological), we have been using [https://simple.wikipedia.org/wiki/Pesticide pesticides] and inputs that are harmful to the environment and to our health. | Since then, the impact of human activity on its environment has been growing.

* [[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.
