Food waste is 3rd biggest source of greenhouse gas
Food waste amounts to 1.3 billion tons per year, which would make it the third-largest emitter of greenhouse gases, if it were a country, Newsweek reported.
Newsweek, citing international studies, said the amount of food lost per year is enough to feed 2 billion people.
In spite of this, it said 795 million people go hungry around the world.
However, food waste is also linked to climate change because the energy and resources used to make them contribute to global warming but the potential to feed more people is lost.
The report said food consumption per person more or less stayed the same over the past five decades while the availability of food rises. In 2010, the food industry produced more than 20 percent of greenhouse gas emissions.
But the food are not reaching people who are always hungry.
The report said by 2050, “food waste will amount to between 1.9 and 2.5 gigatons of CO2 per year from the agriculture sector, compared with the 0.5 gigatons of CO2 attributable to food waste now. By then, 14 percent of total agriculture emissions will come from making food that will feed no one.”
That is why scientists are urging that people to mitigate climate change by avoiding food loss and waste.
The Food and Agriculture Organization is optimistic that human behavior can change, which means hope for the environment.
A few countries have prohibited restaurants and supermarkets from throwing edible food away, and instead required them to donate in food banks.
Others have started to sell “ugly” or deformed fruits and vegetables.
