In 1850 the weight of all the world's wild mammals equalled the weight of humans and our livestock
Today they are outweighed 1 to 20
Reconfiguring life on this planet to produce cheap meat and dairy

At this point "working people" just specifically means drivers doesn't it.

Imagine even just reducing meat and dairy enough to free up even a quarter of this. The JOY it would bring. The meaningful reconnection of local cultures to place and nature.
"If the world adopted a plant-based diet, we would reduce global agricultural land use from 4 to 1 billion hectares"
Imagine 3 billion more hectares for fully wild ecosystems.
Diet is THE elephant in the room when it comes to reversing nature collapse.

We could reduce the amount of land used for grazing and croplands used to grow animal feed.

The devastation on its way is unimaginable - like nothing humanity has ever witnessed before - and everyone will wish they had been climate activists and ‘hysterics’ when they had the chance. We are in a moment of unprecedented stupidity

We need to plant many more native trees in urban spaces, and better protect and value existing ones. This helps nature and wildlife. It's #ClimateAction. It reduces floods, pollution and urban heating. And it improves our lives. More: bit.ly/2eMCYds

Nobody ever planted a tree in this photo. It was a working gravel pit 30 years ago.
We need to get over our obsession with planting trees and let nature do the job. The results are just SO much better.
It's also about realising we are not, in fact, central to everything. 🌍
