A lot of people talk about carbon footprint, but what does it really represent? According to the World Health Organisation (WHO), an individual’s carbon footprint is a measure of the impact his or her activities have on the amount of carbon dioxide (CO2) produced through the resultant burning of fossil fuels. It is expressed as a weight of CO2 emissions produced in tonnes. in 2008, the WHO published a report on the world’s carbon footprint per capita. It was said that global experts called for a target limit of approximately two tonnes per person per year, but that average stood at four tonnes per person, with wide variation between countries. In simple terms, our actions have a direct effect on the environment. Simple changes in our daily life can reduce our footprint. According to a report published by the UK newspaper The Guardian, eating less red meat would be a better way for people to cut carbon emissions than giving up their cars. This is because meat production has a heavy impact on the environment. Climate change caused by the carbon emissions affects the determinants of health, such as clean air, safe drinking water, sufficient food and secure shelter. The WHO states that between the years 2030 and 2050, climate change is expected to cause approximately 250,000 additional deaths per year. And we are responsible...
