1 Impacts of consumer choice on the environment

2 Air miles / food miles Flowers Perishable Must have air freight More carbon dioxide released More impact on Global Warming BUT … Kenyans say less GH Gas emission that if grown in heated greenhouses in Europe DO / DON’T BUY KENYAN FLOWERS?

3 LOCALLY GROWN MAY NOT LEAD TO LESS CARBON EMISSION. Even allowing for extra transport Spanish tomatoes release much less carbon than those grown in heated greenhouses in colder countries

4 Some foodstuffs are shipped not flown US food emissions found 83% of carbon emissions in the food system result from food production, 5% from wholesaling and retailing food, and 11% from transporting it. SO BUY IT IF ITS SHIPPED!

5 Pressure for low prices = intensive production Pesticide use in a banana plantation (Ecuador) can be 20 times greater than the average on crops in MEDCs. Pesticide exposure causes illness among workers and pollution of land, watercourses and aquifers, and a reduction in biological diversity.

6 Irrigation – water stores dry up In the 1960s, Aral Sea (between Kazakhstan and Uzbekistan) fishing was big business—ships like these brought in 50,000 tons of fish a year. In the 1960s river water which normally flowed into the Aral Sea from the mountains was diverted to irrigate cotton and rice fields

7 Subsistence Farmers pushed to marginal lands Kenyan flowers 23% of GDP 150,000 employees The industry is massively water intensive. Subsistence farmers growing food Pushed to more marginal land … Not enough water - Soil erosion occurs – called DESERTIFICATION

8 Food Waste – by retailers & consumers
