 So I've been working in the field quite intensively before coming here so I have a lot of knowledge on how supply chain looks like and those are small holder and plantations but I don't really understand where does the concept of sustainability come from and why sometimes the western world is demanding a lot in the developing markets. So that's why my manager actually encouraged me to come to Cambridge, come into the heart where a lot of the concepts on human rights, environmental policies come from, it really helped me to get more comprehensive view and also helped me to find a platform to share some of my own observations from my experience as well.
