Would you believe that cow farts contribute to air pollution! I read this article (see link below) about these cows in Callifornia.
The article states that: "The San Joaquin Valley is home to a thriving dairy industry that includes some 2.5 million cattle. With more new dairy operations planned, an additional 400,000 cows are expected to arrive in the valley within the next few years.
But the dairyland is also known for its smog. Over the last six years the valley has violated the federal limit on smog levels more often than any other region in the country. "The valley air basin harbors some of the worst air quality in the entire country, and on far too many days air quality is unhealthy," said Kelly Hogan Malay of the San Joaquin Valley Air Pollution Control District."
Does that mean that cows contribute to Global Warming?
Each student must post a comment about this.
