The food we eat contributes equally to the greenhouse emission as the other factors. According to Tubiello all the steps that food takes from the farm in reaching our plates cause 25 to 30% greenhouse emissions.
Emissions Database for Global Atmospheric Research highlighted the fact that developing countries are contributing more to the food system emission, compared to the developed countries.
It is mainly meat consumption that is responsible largely for food system emissions. When talking about production, animals use more land than plants. Meat consumption is endangering our existence in the world.
In this regard, Brent Kim, a program officer at Johns Hopkins Center for a Livable Future, suggests that residents of the US should shift from meat to plants. Consuming plants for food mean fewer emissions while food production.
The changed food choices are the only way we can save the earth from food system emissions.
