Have you ever looked at the leftover food on your plate at school or after a family dinner and wondered where it goes? While it may seem like a small amount, it is part of a much larger global issue. Worldwide, about one-third of all food produced is never eaten. This is not a minor problem; it has serious consequences for our planet, contributing to the waste of resources like water and energy used to grow and transport that food.

When food ends up in a landfill, it decomposes without oxygen and produces methane, a powerful greenhouse gas. It is over 25 times more potent at trapping heat in the atmosphere than carbon dioxide, making food waste a significant driver of climate change. The journey from our plates to the landfill, therefore, has a surprisingly large and harmful environmental footprint that many people are not aware of.

In Vietnam, this issue is especially visible during large celebrations like Tết, where preparing abundant food is a tradition. However, this often leads to a large amount of waste. Fortunately, awareness is growing, and organizations are taking action. For example, Food Bank Vietnam works to rescue surplus food from supermarkets, farms, and restaurants. Their mission is to redistribute this edible food to orphanages, elderly homes, and people in need, turning potential waste into valuable meals.

The good news is that we can all be part of the solution. As young people, you can make a difference starting today. Simple actions include being more mindful of what you buy, taking smaller portions of food to avoid leftovers, and creatively using uneaten food for other meals. By making small changes in our daily habits, we can collectively reduce the amount of food that ends up in the landfill and help protect our environment.
