"It's time for us to keep better track of our livestock as they cross borders"

In this quote, Collin C. Peterson is emphasizing the value of monitoring and handling livestock as they move across borders. This could describe the transportation of animals for trade or grazing purposes. By stating "it's time," Peterson is suggesting that this is a pushing problem that needs to be addressed. Making use of the word "us" indicates that it is a cumulative duty, perhaps directed towards farmers, government authorities, or other stakeholders associated with the animals market. The expression "keep much better track" recommends that there might have been previous issues with monitoring livestock, and it is now necessary to enhance this procedure. In general, this quote highlights the need for efficient and effective management of livestock as they cross borders.
