To determine how much food is wasted every year, we need to consider the global estimates provided by various organizations and studies on food waste. Based on extensive research and reports from organizations such as the United Nations Food and Agriculture Organization (FAO), it has been estimated that approximately one-third (33%) of all food produced globally is wasted each year.
Here's an explanation of the given options:
1. 100 million tons:
- This specific number is often cited in discussions about food waste, but it represents just a portion of the global figure. While significant, it does not encompass the global scale of food waste accurately.
2. 25 tons:
- This is an extremely low figure, vastly underestimating the scale of food waste. It is not a realistic estimate for yearly global food waste.
3. 10% of all food produced:
- This is also an underestimation. Although 10% would still represent a large amount of waste, it is not consistent with the most widely accepted estimates.
4. 33% of all food produced:
- According to the FAO and other authoritative sources, approximately one-third of all food produced for human consumption is lost or wasted globally each year. This is equivalent to about 1.3 billion tons annually. This option aligns with the accepted data.
Based on the above explanations, the correct answer is:
33% of all food produced
