The industrial farming is hugely responsible for the ecological destruction on the planet, for the extinction of thousands of species and for the ruin of millions of small farmers (see the FAO report).
It takes part in the depletion of water resources and widely contributes to the global warming.
Livestock farming, single-handedly, is responsible for 18% of the greenhouse gas emission. Each year, 65 billion of animals are bred in insufferable conditions just to be killed afterwards. To feed them, millions of forest acres are cut down to grow soya and corn, thus exhausting and polluting the soil (because of the pesticides). Many populations and species who used to live there are deported.
A few agents of the food-processing industry are now controlling most of the seeds, as the giants of the retail chain are controlling a major part of production, retailing and food prices. Our ability to feed ourselves by our own means is in danger.
Cultivate and learn about permaculture or agroecology.
On market places, try to find small independent producers or independent organic stores (such as Biocoop), join an AMAP, join or launch an Incredible Edible group, use direct systems of supply with small producers, such as La Ruche qui dit oui.
Find on Le Marché Citoyen a map of organic stores and producers close to your place.
