Dangerous climate change
“On current trends, average global
temperatures could rise by 2 - 3°C within the next fifty years or so, leading to many
severe impacts, often mediated by water,
including more frequent droughts and
floods”
(Stern, 2006)

“The rich will find their world to be more expensive, inconvenient, uncomfortable, disrupted and colourless – in general, more
unpleasant and unpredictable, perhaps greatly so. The poor will
die.”

Grain and dairy export subsidies and import restrictions are creating an imbalance in food availability and livelihoods between countries
Fair and sustainable trade arrangements?

The food and agriculture sector contributes 16-29% of total global GHG emissions
~ 80% of agriculture’s GHG emissions arise directly from the livestock sector
