It is best to reduce the amount waste first through prevention and minimisation. The next best method is to reuse existing products to extend their lifecycle. These approaches are better than…
Cheese as a food product produces large amounts of carbon emissions. Most of the emissions in cheese production comes from the burps of cows. The way cows digest food mean that they produce methane, which is a greenhouse gas which contributes to global warming. Climate change scientists, such as Professor Bernes-Lee, argue cheese should be…
