The framework has come just in time. This agreement to protect 30% of Earth's lands, rivers, lakes, and wetlands is a step in the right direction. It can prevent mass extinctions, bolster resilience to climate change, safeguard marine ecosystems, and allow humanity to transition towards a nature-positive world.
It's unlikely that this will be fully implemented, as shown by past UN treaties. The agreement could be undermined by its failure to mobilize the promised resources as the financial commitments — including the pledge to increase overall biodiversity financing to $200B a year from all sources — are not legally binding. Also, the US is not a party to the Convention on Biological Diversity.
There's a 32% chance that the European Union will achieve its 2030 Paris Climate Agreement goals, according to the Metaculus prediction community.
