All living things need to eat every day to survive, most notably humans. As the effects of climate change become increasingly evident, the choices humans make for food have more significance now than ever.

More and more people are cooking at home, and this could be an opportunity to use food and fight climate change during the pandemic. All there is to do is swap and tweak some eating habits to make a more positive impact both to one's health and on the planet.

Minimize Eating Red Meat

Minimizing or cutting red meat and animal consumption has the most significant immediate impact on fighting climate change.

GreenChoice CEO and founder Galen Karlan-Mason said that in a study in 2018 published in the journal Science, a diet with no meat reduces greenhouse gas emissions by 49% as well as water-scarcity weighted footprint by 19%.

He mentioned several factors that make industrial agriculture one of the most environmentally demanding processes in food production globally. For instance, the farmer's mono-crop corn and soy then process it to become feed which is then shipped to the cattle, and provide land and water for the cattle to survive. This process is done, all the while the animal releases methane gas daily.

However, plant-eating animals are no one-to-one replacement for steaks and sausages. Associate professor and chair of the Montclair State University's nutrition and food studies, Douglas Murray, said that soy production is second to beef in environmental damage. That means replacing beef with soy is also like replacing the first-degree murder with second-degree murder.

According to Harvard Medical School, these processed burgers contain more sodium and are just as high in saturated fat as the original beef patties. Choosing a meatless option for a burger is not a free pass to eating a soy-based burger daily.

Eat unprocessed foods with a lesser carbon footprint

Vegetarian protein sources might be the best swap-in for meat. As noted in the 2018 Science study, most vegetables have less carbon footprint than even the fish, eggs, and dairy, which are all considered as least impactful animal protein sources.

A plant-based diet may include high-protein vegetables, such as beans, quinoa, leafy greens, and unprocessed foods or ingredients. Eating a more plant-based diet may be a small change, but studies show that it can have a positive impact on one's health, like weight loss, lower risks for cancer, and heart disease.

Incorporating these foods into the diet is now made easier thanks to a new popular mindset that embraces recipes using these ingredients. Plus, keeping quinoa and beans on hand makes it easier to cook from the pantry more often. Hence, skipping the frequent grocery store visits during this pandemic.

On the other hand, eggs are also considered a climate-friendly change in the diet, especially those coming from a local farm as they are packed with a lot of protein, and they are less environmentally damaging. For those who want to switch to non-dairy milk, oats, soy, and hazelnut milk are the best alternatives.

What About Local and Seafood?

According to the USDA, the number of farmers' markets in the country has increased significantly from 1,755 in 1999 to 8,771 in 2019. While the mantra "eat local" is an essential part of the economy, it is not necessary to look for something that is not readily available.

Moreover, it is surprising that land use in growing these local foods account for 80% of a food's carbon footprint compared to only 5% of the transport.

Conversely, it is recommended to skip farmed shrimps as they have the greatest environmental impact in the seafood category. They are the largest driver of mangrove deforestation, which are trees that play a significant role in absorbing carbon dioxide.

For seafood alternatives, anchovies and sardines do not take as much fuel or energy to process compared to tuna. Also, oysters and mussels help clean up waterways by their filtering and eating habits in terms of sustainable aquaculture.
