Practically - To scan the products I buy and reject those with Palm Oil in the ingredients list wherever possible
Proactively - To actively speak to my Supermarket Manager and ask him if he/she is aware of the issue and if not, who his Superior is and how I contact that person to make them aware and thereby influence Supermarket Purchasing Policy.
Positively - To sign the following petitions (and any others I become aware of) as a positive way of adding my name to the growing list of concerned consumers who value their health and prospects for endangered species such as Orang Utans.
