A report which always makes fairly shocking reading is the Living Planet report from WWF.
This is the latest edition of the report, dating from 2022. There will be at least one more update before the new specification starts to be prepared for first teaching.
A young person's version of the report is also available.
The Young Person's report would be a fantastic resource for the course. It has a global scale look at key ecosystems such as the Amazon, and the world's oceans, and is presented in an easily accessible visual style.
