7. A large group of grays lived in the Atlantic for thousands of years: Scott Noakes, “Georgia’s Pleistocene Atlantic Gray Whales,” Gray’s Reef National Marine Sanctuary , http://graysreef.noaa.gov/science/research/gray_whale/welcome.html.
8. 20,000–30,000 individuals: This number is a point of some debate, as populations change every year, and the only way we can count them is by observing how many different individuals pass by observation stations along the Pacific Coast. The number that scientists seem to agree on most is 22,000 individuals, based on average numbers from data collected over the past two decades. The population is growing by over 2 percent every year, and in 2012 over 200 babies were born. I’m basing my numbers on two sources: S. Elizabeth Alter, Eric Rynes, and Stephen Palumbi, “DNA Evidence for Historic Population Size and Past Ecosystem Impacts of Gray Whales,” PNAS 104 (September 18, 2007): 15162–67, and the annual population estimate reports issued by NOAA, which collects data from several observation stations along the coast from Alaska to Mexico ( http://www.nmfs.noaa.gov/pr/sars/).

10. in 1949 the newly formed International Whaling Commission: The IWC was established in 1946, and included several member states such as the United States, Japan, and the then Soviet Union. You can see a record of every annual meeting online ( http://www.iwcoffice.org/meetings/historical.htm). What’s interesting about this and other early conservation groups is that it combined the interests of environmentalism with commercial interests. It’s also worth noting that some Inuit groups are still permitted to hunt a small number of grays every year.
11. Others argue, based on genetic data: Alter et al., “DNA Evidence for Historic Population Size.”

CHAPTER FOURTEEN: THE MUTATING METROPOLIS
1. In the past decade, the number of people on Earth living in cities: The highlights of “World Urbanization Prospects” (last revised April 2012), a U.N. Report on population demographics in cities, gives us this statistic, adding that “urban dwellers will likely account for 86 percent of the population in the more developed regions and for 64 percent of that in the less developed regions.” You can view the U.N.’s World Urbanization Prospects report, and the data that informs it, on the U.N. website at http://esa.un.org/unpd/wup/index.htm.
2. The World Without Us: Alan Weisman, The World Without Us (New York: Thomas Dunne Books, 2007).
3. It would require us to regulate the bodies of billions of women: I am talking here about what it would take to lower the population over the next half century. Many studies have shown that birth rates plummet dramatically in countries where women receive the same educational and economic opportunities as men. It is my fervent hope that over the long term, women’s equality with men around the world will lead to a population size that is better adapted to the Earth’s environment. Until that happens, however, we must accept that our population is growing and prepare for it.
