Among growing concerns about rising food prices and global warming, many Americans are taking a closer look at what they do and don’t eat.
Research in the US estimates that at least 14 percent of purchased food ends up in the garbage.Some way view this as a call to return to the”clean your plate” atiitude, which was popularized in the mid-twentieth century, but this would be unwise.With a rising overweight population and a growing national health crisis, it’s time for a new approach.Instead,we should view these figures as motivation to reduce waste,cut grocery costs and maintain our health by shopping and eating smarter.
Food waste reportedly makes up about 12 percent of waste material.Aside from the costly operation budgets of the equipment,the environment is paying the real price.As organic material(like vegetables,fruits and grains)decompose in the garbage,they release the greenhouse gas methane(甲烷)into the environment.
In fact,garbage is the largest source of methane emissions(散发)in the US.While composting plant food, which does not produce methane,is one solution,strategies for wasting less food shoule also be explored.
According to a survey in the UK,one major source of food waste is “over shopping”.Buying more food than we need is easy to do when we shop without a list or when “buy one,get one free”offers tempt us to put food that will often go to waste into our shopping baskets.
The solution: shop smarter.Check your refrigerator to see what needs to be used or frozen before it becomes bad.Check your calendar to see if there are meals that you know you will be eating away from home.
Before you go to the store,decide how many days worth of food you need.Then ,take a few minutes to prepare a shopping list.Don’t make things different—no need to decide what will be served each day—just plan enough breakfast,lunch and dinner meals to last until your next grocery run.
