It's also hard to balance afforestation without causing scarcity of water and displacement of native forest habitats. For example, instances where shrubs are misclassified as forests inflate the report figures. China seems to be the global leader in biodiversity loss, with about 80% of its coral reefs and 73% of its mangroves gone since 1950. Everyone knows their abusive fishing practices, and the millions of tons of plastic pollution into the ocean every year.
So, keep up the good environmental efforts, China, and hope you do even better.
