There is so much involved in growing, processing, transporting, and disposing food. This covers climate-related greenhouse gas pollution at all levels of the food chain, including water, fertilizers, processing, labour and more. Unfortunately, at the end of this, much of this food ends up in the trash. Wasted food is harmful to the environment as it creates an influx of methane gas. Methane is a powerful greenhouse gas which contributes to the problem of global warming.
There are some areas where it is unavoidable to waste food, such as modern day farming. Similarly, food lost in packing houses, manufacturing, and transportation facilities. On the other hand, food waste in households is something we can control. There is a large problem of overbuying at the consumer level. Buying in bulk in large retail stores often results in too much food that ends up getting spoiled. Another common thing is throwing food away by the “sell by” date. The “sell by” or “use by” dates are not actually the same as the expiry date. In conclusion, try not to throw away leftovers and buy your food accordingly.
