Innovations in technology can also enhance sustainability efforts in animal agriculture. I was amazed to see the technology employed when I visited the dairy research barn at Penn State University’s animal science department. Each dairy cow is closely monitored with wearable sensors that provide information about their activity (a cow who isn’t moving a lot may have an infection or other health issue), body temperature, and milk production so they can more efficiently and accurately monitor their health and welfare.
Eating less meat is better for the planet
Some people believe that eating less meat is the answer to reducing the toll that agriculture, as a whole, takes on the earth. That may sound like a simple solution, but it’s not so simple.
A recent movement aims to replace meat with other forms of protein. As of now, it’s hard to say what the final answers will be, but it’ll likely be a combination of compromises. As previously mentioned, sustainability requires economic viability to be upheld. Critics are quick to point the finger at beef in particular, for producing excess methane (through burps primarily). They believe that ruminant animals like cows are key polluters when it comes to GHG. A lot of sources of data exist but no agreement on how the data is collected and what it means overall.
