2、hown that the pollution from cows canbe reduced by adding a little seaweed to their food.Scientists first discovered that seaweed could help control methane from cows several years ago.But this work was done in a laboratory,there were many questions about whether the idea could work in real life.In

3、the lab studies,the cows were given quite a bit of seaweed,and they would cause losing weight.That wasnt helpful,since cows are often sold by weight.It also wasnt clear if the seaweed would stop working if it was used for a longer period of time.Now,scientists from the University of California,Davis
