LOS ALIMENTOS ORGÁNICOS no sólo afectan el medio ambiente igual que los industriales, sino que podrían contribuir al calentamiento global en mayor medida que la agricultura intensiva:

Tomatoes

* 122sq m of land is needed to produce a tonne of organic vine tomatoes. The figure for conventionally-grown loose tomatoes is 19sq m.

* Energy needed to grow organic tomatoes is 1.9 times that of conventional methods.

* Organic tomatoes grown in heated greenhouses in Britain generate one hundred times the amount of CO2 per kilogram produced by tomatoes in unheated greenhouses in southern Spain.

Milk

* Requires 80 per cent more land to produce per unit than conventional milk.

* Produces nearly 20 per cent more carbon dioxide and almost double the amount of other by-products that can lead to acidification of soil and pollution of water courses.

Chickens

* Organic birds require 25 per cent more energy to rear and grow than conventional methods.

* The amount of CO2 generated per bird is 6.7kg for organic compared to 4.6kg for conventional battery or barn hens.

* Eutrophication, the potential for nutrient-rich by-products to pollute water courses, is measured at 86 for organic compared to 49 for conventional.

* The depletion of natural resources is measured at 99 for organic birds compared to 29 for battery or barn hens.
