From sufficiency to regeneration: paths for the next decade

ZERO

From sufficiency to regeneration: paths for the next decade

In a context of ecological changes and crises, we propose a dual reflection on the limits and possibilities of the planet. Initially, we explore ways to regenerate food and production systems, proposing a culture of sufficiency and equity that respects planetary limits. We then instigate the debate based on the question: is it possible to reserve half of the planet as “pure nature”?

At the end of the debates, we showed the documentary Ecossistema ZERO, by Paulo Lucas, which portrays 10 years of the ZERO Association, and its role in building an environmentally fair future.

7:00 p.m. – Biodiversity: is it possible to reserve half the planet as ‘pure nature’?
Preserving a large area of the planet free from human activity requires us to increase the sustainability of our activities, such as fishing or agriculture, and to have more sustainable cities, but how can we reverse the trend of not achieving these goals when we are in an emergency situation?
