Growing up, Kate had no interest in environmental causes. However, when she entered college in 2018, her study of geography coupled with peer influence led her to becoming increasingly conscious about environmental protection. She made changes in her own lifestyle but was frustrated seeing others use plastic products. So, Kate launched a nation-wide campaign in Singapore called Bring Your Own Bottle. The campaign cooperated with beverage companies to offer customers discounts if they bring their own containers or bottles. Last year, Kate also worked with more than 230 Singaporean hawkers and drink stalls to encourage the reduction in plastic usage.
