Jonathan Foley looks at what he calls the “other inconvenient truth” – the skyrocketing demand for food that means agriculture has become the largest driver of climate change and biodiversity and environmental destruction, in this informative TED talk.
Blue & Green Tomorrow is currently running a crowdfunder to ensure its survival. Please pledge.
Forley uses clear graphics and photos to demonstrate how dominant humans have become and the extent of our agriculture and its impacts. For example he emphasises how agriculture is putting immense pressure on water resources, particularly when farmland is in dry regions.
The figures in the presentation are stark, for instance the world currently uses around half of the frewhwater that is sustainable, with agriculture accounting for around 70% of this. Agriculture also accounts for a significant portion of greenhouse gas emissions and land use.
