 <u>Why go through the numbers?</u>

+Researching the matter may be a tremendous, easily biased and forever evoluting task, the spreadsheet below is thus here published to allow us, as consumers and climate conscious citizens, to take a first step towards the understanding of the complex “environmental impact” of various foods. This step may therefore allow us to realize that there is no systematic relationship between land use, CO2 emission, soil depletion or water use. For instance, the document challenges popular believes such as “dairy is better for the planet than meat” or ”sea food has less impact than meat”. The numbers confirming that dairy production would produce more than 2x CO2, and contribute 4x more to the eutrophisation of the soil than pig meat as well as that crustaceans would produce nearly 3x more C02 and contribute 2x more to the eutrophisation of the waters.
 We will here be able to compare the overall CO2 emissions, the land use, the acidification, the eutrophisation as well as the water scarcity impacted by the 40 most produced foods in the world. These numbers, gathered from the largest database to date: 40,000 farms, across 119 countries include high impact industrials as well as small scale, organic or bio dynamic farms.
+<u>Note</u>
+As it gathers data from worldwide sources, this spreadsheet is not a set answer which should impact your diet. For it to be applied, you would rather delve further into statistics applied to your country or region of residence (as the results will most surely differ).

+These numbers are gathered from the largest database to date of the kind: 40,000 farms, across 119 countries.
+This comparative spreadsheet is based on 2 documents included in the research study titled “[https://science.sciencemag.org/content/360/6392/987/ Reducing food’s environmental impacts through producers and consumers]” published by J. Poore<ref>Zoologist from the School of Geography & Environment, The Queen's College& University of Oxford</ref> and T.
