I am an Honours student studying Biomedical Sciences. Through the years of my study, I have used the public transport to reduce my fossil fuel footprint. This is despite the fact that I can drive to and from the university. According to the United Nations' twitter page, we can cut the carbon dioxide emission in the cities by up to 50% if we switch from cars to buses. I want to play my part and advocate this to my friends, family and relatives. I have implemented this action and plan to maintain this throughout my studies and career. I recommend catching the public transport or using other modes of transport such as bicycles or car pooling so that we could play our role in reducing the emission of greenhouse gases. The use of public transport, bicycles and walks can also have positive impact on our health and wellbeing.
