What nations should do to restore biodiversity and reverse pollution

The 6th Session of the United Nations Environmental Assembly (UNEA) opens on February 26th to March 1st 2024, in Nairobi, known as United Nations Office in Nairobi (UNON).
UNON is the only UN headquarters in the global South, although the UN has offices globally. The other three are in New York, Geneva and Vienna.

The theme of the 6th UNEA is "Effective, inclusive, and sustainable multilateral actions to tackle climate change, biodiversity loss, and pollution," aiming to accelerate actions to mitigate climate change, biodiversity loss, and pollution, which are urgent existential crises that we must address now to survive and achieve the Sustainable Development Goals (SDGs) by 2030.
