<human>: Can you succinctly summarize the text in 1-3 sentences?

I work in a lab where I have a research associate working under my actual mentor that I suppose is my boss too but he also works in the lab. Anyway we work back to back every day. He is SUPER into recycling and being earth friendly- for example- he will compare protocols and choose the one that is more eco friendly, or grow bacteria in tubes that are reusable but compromises the sterility. 

Anyway he has started watching when I throw things away at my desk and telling me to go recycle it. I am not an earth hating monster however I feel that if I want to throw a piece of paper away at my desk that's my choice not his. It has gotten progressively worse where if I say I don't feel like taking a trip down the hall to the recycling bin he will remind me that he isn't having children and I am and that he is doing this for them. The point where he is crossing the line is that he has now started going through my trash and taking things out to recycle them. I mean it's mostly lab stuff like gloves in there but I do throw away personal things too like prescription bags and whatnot. I just feel this is crossing a personal boundary and I don't know how to ask him to stop!
<bot>: A person above me at work is so into recycling he has started going through my trash. I feel invaded. How can I ask him to stop?
