The federal government is in the process of trying to reduce methane gas emissions.
It believes it should start with cattle. But what do cows and bulls have to do with global warming?
Cattle are the biggest producers of methane gas, however, a local beef specialist says the numbers are not as alarming as you think.
"I think that when you look how much cattle contribute to the greenhouse gases all of animal agriculture is only 2.8 percent of greenhouse gases, and we've been improving that number lower and lower," Travis Meteer, University of Illinois Extension, Beef Specialist, said.
The government wants reduce emissions by 25 percent by 2020.
A local senator says its a good idea but it may not be feasible.
"But the reality of what they are trying to do is very questionable, now on the other hand I will have to say this, it is starting out to be voluntary but sometimes things that start off voluntary are mandatory," U.S. Senator Chuck Grassley, (R) from Iowa, said.
At the Orr Research Center, they have more than 100 head of cattle.
If the government imposes standards for reducing emissions, it could reduce their numbers.
"I think a tax is something that our producers would be hesitant toward of course that will increase the price of food, the production practice that go into producing food for Americans to eat,?? Meteer said.
While Meteer does acknowledge that the cost might pass on to consumers, it also means the Earth will be a little better off.
