Cattle are a source of greenhouse gases, and experts say making subtle changes to one's diet can have an impact.

For years, animal agriculture has been a driver of economic growth across Indiana, but it could be damaging the environment?
One Indiana city could serve as a blueprint for the future as more Americans turn to plant-based protein instead of meat.
Most agriculture-related greenhouse gases come from large animals such as cattle and lamb. The animals graze on a large amount of grass.
In addition to the resources animals consume, cattle also release methane gas into the air through burping and flatulence. Burps are by far the larger source of greenhouse gases.
Here in Indiana and throughout the Midwest, animal diets are often supplemented with large quantities of grain.
Purdue University Climate Research Center Director Jeff Dukes says Americans are consuming significantly more meat today than ever before, which is putting a strain on the global supply chain.
“Even if you went back 50 years, people in the U.S. ate much less meat than they do today,” Dukes said. “If we get down to those levels where people are eating meat at the rate we did 50 years ago that’s getting a lot closer to sustainability.”
But, he’s not trying to keep people from eating meat entirely; Dukes admits his son is a fan of cheeseburgers.
“Cutting down a little bit is pretty easy just thinking every once in a while, about not having a cheeseburger or not having a steak,"Dukes says. “Switching to a more environmentally friendly option — that’s a pretty easy thing to do once.”
According to Dukes, estimates show about 18 percent of current greenhouse gases come from large animals like cattle.
For Farmers And Ranchers, Climate Change Argument Is Nuanced
A UN climate change report published earlier this year says raising meat requires more land and water resources than plants.
Jamie Hodgen, however, believes that statistic doesn’t tell the full story.
She grew up around cows, and comes from a family of ranchers in New Mexico. She’s currently raising her own on a farm in Roachdale and studies them professionally as a food scientist.
“We’re each trying to utilize the resources that we have in our area to raise our cattle, because in a lot of cases conservation means survival for the next year,” she looking over her cattle. “Having enough grass the make sure our cows can eat over the winter and other things we do to make sure that the land is available for my kids to come back and farm.”
Hodgen says farmers and the cattle they raise help support local economies. She and other rural economic development officials argue agriculture support schools in Roachdale and throughout the county. She finds it hard to believe plant-based alternatives will impact her operation.
“Why mess with a good thing?” Hodgen asks.She understands why some people don’t want to eat meat, but still believes the protein one receives is hard to replicate with a plant-based diet.
Shelbyville, Indiana: An Unlikely Place For The Nation's Largest Plant-Based Protein Facility?
However, the plant-based market is growing — and fast. That’s perhaps best illustrated in Shelby County.
Chicago-based Greenleaf foods recently announced it was building the largest plant-based protein production facility in North America there. The industry as a whole has seen double-digit growth.

“We started the process about a year and a half ago as we recognize where this category was going and our commitment to invest in adding more capacity into the system,” Dan Curtin, Greenleaf’s President and CEO said. The company “knew we needed to build another facility and we did extensive studies to figure out where was the best place.”
The Shelbyville facility will produce nearly 10 million pounds of plant-based protein per year when it is fully operational.
Curtin says the facility’s central location will contribute to the company’s conservation pledge and aid in the creation of new products. In addition to a significant shift in consumer tastes, he believes the taste of the products themselves keep people coming back.
“We actually did some product tastings down in Shelbyville,” he said. “We had a barbecue down there and a number of people from the town come." Curtin said "they were incredibly impressed with the quality of the products, the type of product it was and it was a bit of surprise yourself.”
Curtin says the meatless industry is quite fluid, but believes the market is here to stay.
“This category is changing so rapidly, there’s no doubt that this is a trend, it’s not a fad,” he said. “People are looking for options, they’re looking for alternatives, our plant-based food products give them those options.”
Most admit the taste has gotten better. Among them is Shelbyville’s Director of Economic Development, Brian Asher.
“Really it tastes like a normal burger,” Asher said.
A self-described a meat-eater, Asher admits in recent years the taste plant-based alternatives have improved.
“I hate to say it, but the taste of it is also a big change," he said from his office overlooking the town square. "Your soybean burgers back in the day compared to the taste of them now is a lot different.”
Asher says the Greenleaf meatless burgers went faster than traditional burgers and hot dogs at the Shelbyville event.
Despite all of the growth, Hodgen admitted farmers and ranchers should do a better job communicating what she calls a net-positive impact on the environment.
“When you put a pound of corn into a ruminant animal that has a very cool digestive system that can make a higher quality protein you actually end up with a lower calorie, higher quality product with all of your digestible amino acids that you’re not going to find if you’re looking at plant-based as a nutritional substitute for beef," she said.
Dukes disagrees. Nearly all of the analyses he’s read outline plant-based alternatives lead to a lower impact on the environment than beef products.
Regardless, nearly everyone agrees the plant-based industry is a substitute — rather than a threat to the meat industry.
Greenleaf is an independent subsidiary of Maple Leaf Foods, a packaged meat company.
