Step-by-step explanation:
Since the 1950s, there has been a significant increase in both dairy production and dairy cows in the dairy industry.
Prior to the 1950s, dairy production was primarily done on small farms with a small number of cows. However, advancements in technology, breeding techniques, and management practices have led to higher milk yields per cow and increased efficiency in dairy production.
As a result, today, we have fewer cows but a higher overall production of milk and dairy products.
