This week temporary forests were installed in London and Vienna
This week on Dezeen, Es Devlin created the Forest for Change at the London Design Biennale and Superflux installed fire-blackened pine trees at the Vienna Biennale for Change 2021.
British designer Devlin filled the courtyard of Somerset House, which is the main venue of this year's London Design Biennale, with 400 trees to draw attention to the UN Sustainable Development Goals.
These goals are displayed on colourful mirrored pillars arranged in a clearing at the centre of the forest.
Also aiming to draw attention to the impact of climate change, design studio Superflux installed 415 trees that had been damaged by forest fires around an oasis of living plants.
Called Invocation for Hope, the installation was created at the Museum of Applied Arts in Vienna as part of the Vienna Biennale for Change 2021.

The school said it was "aware of the issues" and was set to begin an investigation.
