Why is food waste bad for the environment?
When food is disposed in a landfill it rots and becomes a significant source of methane – a potent greenhouse gas with 21 times the global warming potential of carbon dioxide. Growing and transporting the food that goes to waste emits as much carbon pollution as 39 million passenger vehicles.
Why is waste bad for climate change?
When food waste ends up in landfill, it rots, producing methane – one of the most damaging greenhouse gases driving up climate change. … And as they break down they emit methane, which is many times more harmful in the short-term to our climate than carbon dioxide (CO2).
What are the cons of food waste?
When food and other organic matter decomposes, it produces methane gas. Methane is a greenhouse gas that is 30 times more potent than carbon dioxide. Since food waste is the biggest component of landfills, landfills are a major source of greenhouse gas emissions.
Why is food waste bad for the economy?
Food waste also drives up prices, reducing the number of people who can afford the healthy food they need. On a local scale, this food waste is a lost opportunity to help feed the food insecure – those who don’t know where or when they’ll have their next meal.
How does food waste affect the society?

The fuel that is burned to process, refrigerate and transport it also adds to the environmental cost.
How does food contribute to climate change?
Between farms and plates, most food-related greenhouse gas emissions are from producing food—particularly beef and dairy. … Food system activities, including producing food, transporting it, and storing wasted food in landfills, produce greenhouse gas (GHG) emissions that contribute to climate change.
Does food waste cause global warming?
Today, an estimated one-third of all the food produced in the world goes to waste. … And if food goes to the landfill and rots, it produces methane—a greenhouse gas even more potent than carbon dioxide. About 6%-8% of all human-caused greenhouse gas emissions could be reduced if we stop wasting food.
