Eating Less Could Help Save the Planet

A recent study suggests that a significant portion of the global population needs to adjust their eating habits to combat climate change. The research, led by Dr. Juan Diego Martinez, indicates that 44% of people worldwide must change their diets to keep global warming below 2 degrees Celsius. The study analyzed data from 112 countries, covering 99% of global food-related greenhouse gas emissions. It divided each country's population into income groups and calculated a food emissions budget for each person. The findings show that half of the global population and 90% of Canadians need to change their diets. This number is expected to rise to 90% globally by 2050 due to increasing emissions and population growth.The study highlights that the world's food systems are responsible for over one-third of human greenhouse gas emissions. The top 15% of emitters contribute 30% of total food emissions, equal to the bottom 50%. This group includes wealthy individuals in high-emission countries like Brazil and Australia. However, the problem is not just for the rich; everyone needs to eat, so everyone can make a difference. So, what can we do? The study suggests eating only what you need and reducing food waste. This means fewer emissions, less cooking, and more tasty leftovers. It also recommends reducing beef consumption, as it accounts for 43% of food-related emissions for the average Canadian. The study acknowledges that this is a big ask, especially in cultures where beef is a staple. The study also encourages voting with your fork, meaning making dietary changes and talking about them. This can influence politicians to care about food system policies. The goal is to make positive changes to our food systems and reduce emissions.
