Scholastic has a good environmental game called Virtual Forest Challenge. It’s very accessible to English Language Learners.
In the game, you are a virtual character going through a typical day. You regularly are faced with having to make choices between decisions that are ecologically helpful and ones that are not — you have to make the call.
I’m adding the game to The Best Sites To Introduce Environmental Issues Into The Classroom, and I’m place the link on my website on the Science page.
