How often do you eat meat? Once a week? Everyday?
If that's the last case, your diet has a huge impact on the planet.
You've probably already heard that the best way to fight climate change is to reduce your meat consumption, but if you're not ready to become vegan, a new study has shown that you can reduce pollutant emissions by exchanging your steak for animal organs.
The meat industry accounts for 14.5% of total global greenhouse gas emissions, more than the direct carbon production of the transport sector.
Livestock products are particularly harmful because cows produce enormous amounts of harmful methane – a greenhouse gas 25 times more powerful than carbon dioxide – when they disgorge or transmit gas.
Despite growing awareness of its negative environmental impacts, we produce and eat more meat than ever before.
But even meat lovers can help reduce emissions by reducing meat waste and adopting a "nose-to-tail" diet, which aims to use every part of the animal.
According to a study published in the journal Environmental Science and Technology, exchanging beef ribs and pork chops for giblets, internal organs and pork feet could lead to a drastic reduction in emissions.
The study on the meat supply chain in Germany found that while reducing total meat consumption, emissions could decrease by 32%, but that eating more offal instead of Popular cuts could also result in a significant reduction.
If 50% fewer offal was discarded during slaughter and consumed as food, emissions could fall by 14%, according to lead author Prof. Gang Liu from the University of Southern Denmark.
There is "a huge potential [to lower emissions] by consuming more by-products and reducing waste all along the supply chain, "Liu said.
He added that the nasal diet was a more effective mitigation strategy than "transforming the [entire] World population vegetarian. "
"So you can use the meat more efficiently," he said, adding that in many Asian countries, the consumption of meat by-products, such as guts and lungs, is common.
Trevor Gulliver, who co-founded the first open-air restaurant, St. John, London, said Western countries "waste horrific amounts of food with all the potentially catastrophic effects of it."
"Offal brings to the Western world the sense of the beast as a whole, gives more value to these cuts and brings greater skills to our kitchens," he said.
