STRASBOURG, France — The European Union’s legislature on Tuesday approved a watered-down plan to better protect nature and fight climate change in the 27-nation bloc, despite opposition from the biggest party in parliament and fierce protests from the farming community. The plan is a key part of the EU’s vaunted European Green Deal that seeks to establish the world’s most ambitious climate and biodiversity targets and make the bloc the global point of reference on all climate issues. Yet the Nature Restoration plan has had an extremely rough ride through the EU’s complicated approval process and only a watered down version will now proceed to a final vote among the EU member states, where it is expected to pass easily. …Under the plan, member states would have to meet restoration targets for specific habitats and species, with the aim of covering at least 20% of the region’s land and sea areas by 2030.
