There are many causes of food waste. One of the most common is over-ordering, which happens when restaurants or other establishments over-produce and end up throwing away the excess. It's important for businesses to be mindful about how much food they order so that they don't end up wasting it. Another way that businesses contribute to food waste is by ordering more than what their customers can finish in one sitting. This often happens when you order an appetizer, like a bowl of soup, but only want a small amount - but there's no option for ordering less than what's recommended.

No matter how much you try to be conscious about your food consumption, there are always some sources of food waste. The first and most important step is to identify the sources of your food waste. Once you know where it comes from, you can take steps to eliminate that specific source.

to Fight Food Waste In 2015, the United Nations General Assembly committed to the Sustainable Development Goals (SDGs) for the year 2030. One of those goals is to reduce food waste by 50 percent by 2030. Although that goal is a long way away, there are some steps you can take today to start reducing your contribution to food waste.

The world wastes 1.3 billion tonnes of food a year. This means that, on average, each person in the world throws away a quarter of their food. This volume of waste is not only morally wrong, but it also has a huge environmental impact. The amount of energy, water and land used to produce this food is all wasted. Can you imagine all the hungry people in the world who could be fed if we didn't waste so much food? The good news is that there are things we can all do to help. And the first step is to understand how and why food gets wasted in the first place.
