Sorter endeligt dit affald, men tro ikke, at det har nær samme effekt som at skære ned på flyrejserne og de røde bøffer.

⚖️ Widespread misperceptions:
Across countries, people underestimated the impact of high-carbon behaviors like flying, eating meat, and electricity supply, while overestimating the impact of low-impact actions such as recycling.
These findings perfectly align with previous studies. (3/8)

Systems change is brought about by the collective actions of individuals.
So individual actions, when supporting systems change, is absolutely fundamental to climate action.

Western democracy is build short term renewed power intervals. That means power needs to take notes of what the people wants. And when people show power that they want change, by changing, change can happen. If they dont. It wont!

This is a really important point. Changing these behaviours now does two things:
1.Makes a start on the drastic lifestyle changes and gets communities thinking creatively and in solidarity
2. Sends a strong political message to #government and #business

Of course, we need system-level changes! But under no circumstances should we discourage people from changing high-impact behaviors like eating less meat, reducing air travel, or consuming less. If people can change now, they should. There’s no reason to wait for the perfect system to arrive first!
