I have argued that if more people were vegetarian, we could free up agricultural land to grow food directly for human consumption, rather than growing food for animals that are then slaughtered for food. Tim Harford has noted that there is another beneficial environmental consequence of a higher level of vegetarianism: It would lead to a lower level of greenhouse gas emissions from the animals that are being raised for food. Even more importantly, there is an enormous environmental cost associated with transporting meat from slaughterhouse to market. Think about that the next time you order a Big Mac.
This blog is intended to go along with Population: An Introduction to Concepts and Issues, by John R. Weeks, published by Cengage Learning. The latest edition is the 12th (it came out in 2015), but this blog is meant to complement any edition of the book by showing the way in which demographic issues are regularly in the news.
