Assignment:
Food waste occurs when edible food is intenetionlly discarded by consumers after they fail to plan their meals properly and store food till it spoils or goes past the exipre date.Food waste that ends up in landfills produces a large amount of methane- a more powerful greenhouse gas than even CO2. For the uninitiated, excess amounts of greenhouse gases such as methane, CO2 and chloroflurocarbons absorb infrared radiation and heat up the earth's atmosphere, causing global warming and climate change.
With agriculture accounting for 70 percent of the water used throughout the world, food waste also represents a great waste of freshwater and ground water resources. It is said that a volume of water roughly three times the volume of Lake Geneva is used just to produce food that is not eaten. By throwing out one kilogram of beef, you are essentially wasting 50,000 liters of water that were used to produce that meat. In the same way, nearly 1000 liters of water are wasted when you pour one glass of milk down the drain.
If you look at land usage, around 1.4 billion hectares of land, which is roughly one-third the world's total agricultural land area, is used to grow food that is wasted. Millions of gallons of oil are also wasted every year to produce food that is not eaten. And all this does not even take into account the negative impacts on biodiversity due to activities like monocropping and converting wild lands into agricultural areas.
To stop food waste,consumers should also try to buy food in accordance with a meal plan so that they don't end up wasting edible food. Food may be cheaper when you purchase in bulk, but in reality, you are not really saving money when all you are doing is chucking it in the bin at the end of the week.
If the food still ends up unfit for human consumption, it can be used for feeding livestock, saving precious resources that would have otherwise been used for producing commercial feed. If the food cannot be reused at all, then we should at least try torecycleit in a responsible manner instead of sending it to the landfills where it continues to rot.
