This is the artist's comment from his Facebook profile:

"We are facing an unprecedented global emergency. Governments have failed to protect us despite the known and recommended solutions. It is therefore our duty to act as quickly as possible.
WE DEMAND:

1. The acknowledgment of the seriousness and urgency of the current ecological crises and honest communication on the subject.

2. The immediate reduction of greenhouse gas emissions to achieve carbon neutrality by 2025, through reduced consumption and a planned decrease in energy use.

3. The immediate halt to the destruction of oceanic and terrestrial ecosystems, which is causing a massive extinction of living species.

4. The creation of a citizens’ assembly responsible for deciding on the measures to be implemented to achieve these objectives and ensuring a fair and equitable transition."
