Hello Dhanya, 
 
I hope you are doing well! Please reference this page from AMCAS. Environment classes are not listed under the science courses. Essentially, you can appeal these classes on your application if you believe they include primarily relevant science-content, however I would not necessarily expect this request to be granted. 
 
Hope this helps! If you have other questions, feel free to respond to this post or attend our advising hours. 
 
Cheers, 
Cate, PMH Co-President
