We will here be able to compare the overall CO2 emissions, the land use, the acidification<ref name=acid />, the eutrophisation<ref name=eutro /> as well as the water scarcity impacted by the 40 most produced foods in the world. These numbers are gathered from the largest database to date: 38,700 farms, across 119 countries includes high impact industrials as well as small scale, organic or bio dynamic farms. | We will here be able to compare the overall CO2 emissions, the land use, the acidification<ref name=acid />, the eutrophisation<ref name=eutro /> as well as the water scarcity impacted by the 40 most produced foods in the world.

|Acidification<ref name=acid>The acidity of a soil is defined by its hydrogen potential (pH). Below a certain threshold (~ 6 on the pH scale), the soil is too acidic for most cultivated plants: it limits biological activity (fertility) and its structure is degraded. Indeed, acidity influences the uptake of nutrients and trace elements by a plant, as well as the presence of deep roots or earthworms that structure and aerate the soil.</ref><br>(kg SO2eq.<ref>soils or waters (ex: ocean acidification due to fish and crustacean water farming)</ref>) | |Acidification<ref name=acid>The acidity of a soil is defined by its hydrogen potential (pH).
