Kourtney Kardashian is very eco-friendly and totally against drinking bottled water from plastic bottles. She is so against using plastic bottles that she banned the use of them in her home. She only uses reusable water bottles and is a big fan of 'Just Water' which was co-founded by a family friend, Jaden Smith. The bottles from Smith's company, 'Just Water,' are made from paper and the lids are made from sugarcane.
Because of how eco-friendly Kourtney is, she shamed sister, Kim Kardashian for drinking out of a plastic water bottle on a recent episode of 'Keeping up with the Kardashian's.' However, fans are now giving her the heat on social media for being seen in the same episode of doing the very same thing she shamed Kim for.
