Here's an article explaining "Why Only Degrowth Will Save The World."
From the introduction...
Let’s be clear. It isn’t ‘climate change’ that’s the problem. It’s a multitude of crises stemming from the fact that our current capitalist economy, predicated on endless accumulation and extraction, has tipped nature out of balance. And if we don’t change this system, we are screwed.
They suggest following these basic principles:
✦ Never extract more than ecosystems can regenerate.
✦ Never waste or pollute more than ecosystems can safely absorb.
And then they propose a plan of action...
End planned obsolescence — Guzzling materials and energy only for them to be useless in a few years, all in the name of the growth imperative, is madness. Policy options include extended warranties on products and the right to repair products. Take the Fairphone, for example.
Cut advertising — Advertising, especially when tied to social media giants like Google and Facebook, is mass manipulation on an unprecedented scale. Hickel calls it an “assault on our consciousness — the colonisation of not only our public spaces but our minds, to make us desire things we don’t need”. Policy options include quotas on ad expenditure, legislation, banning ads in public spaces, and social policies to reduce inequality.
Move from ownership to usership — especially for equipment that is necessary but rarely used. Take lawnmowers, for example, or cars. Common Asset trusts, anyone?
End food waste — Around 50% of all the food produced in the world, about 2 billion tonnes, is wasted every year. This is an insane ecological cost, in terms of energy, land, water, and emissions. Ending this could cut the scale of damage caused by the agricultural industry in half.
Scale down ecologically destructive industries — such as the fossil fuel industry (obviously), the beef industry, the arms industry, the commercial airline industry, etc.
