Globally, often the countries with the highest fertility rates are least able to absorb and attend to the needs of a growing population. Family planning is a large step in ensuring that families are not burdened with more children than they can care for. On a macro level, the increased population, particularly in the poorest parts of the globe, also leads to increased stress on the planet’s resources.
Turning to human ecology, we know that individuals and the environment affect each other. As human populations move into more vulnerable areas, we see an increase in the number of people affected by natural disasters, and we see that human interaction with the environment increases the impact of those disasters. Part of this is simply the numbers: the more people there are on the planet, the more likely it is that some will be affected by a natural disaster.
But it goes beyond that. Movements like 350.org describe how we have already seen five extinctions of massive amounts of life on the planet, and the crisis of global change has put us on the verge of yet another. According to their website, "The number 350 means climate safety: to preserve a livable planet, scientists tell us we must reduce the amount of CO2 in the atmosphere from its current level of 400 parts per million to below 350 ppm" (350.org).
The environment is best described as an ecosystem, one that exists as the interplay of multiple parts including 8.7 million species of life. However dozens of species are going extinct every day, a number 1,000 times to 10,000 times the normal "background rate" and the highest rate since the dinosaurs disappeared 65 million years ago. The Center for Biological Diversity states that this extinction crisis, unlike previous ones caused by natural disasters, is "caused almost entirely by us” (Center for Biological Diversity, n.d.). The growth of the human population, currently over seven billion and expected to rise to nine or ten billion by 2050, perfectly correlates with the rising extinction rate of life on earth.
The four key elements that affect social change that are described in this chapter are the environment, technology, social institutions, and population. In 2005, New Orleans was struck by a devastating hurricane. But it was not just the hurricane that was disastrous. It was the converging of all four of these elements, and the text below will connect the elements by putting the words in parentheses.
Before Hurricane Katrina (environment) hit, poorly coordinated evacuation efforts had left about 25 percent of the population, almost entirely African Americans who lacked private transportation, to suffer the consequences of the coming storm (demographics). Then "after the storm, when the levees broke, thousands more [refugees] came. And the city buses, meant to take them to proper shelters, were underwater" (Sullivan 2005). No public transportation was provided, drinking water and communications were delayed, and FEMA, the Federal Emergency Management Agency (institutions), was headed by an appointee with no real experience in emergency management. Those who were eventually evacuated did not know where they were being sent or how to contact family members. African Americans were sent the farthest from their homes. When the displaced began to return, public housing had not been reestablished, yet the Superdome stadium, which had served as a temporary disaster shelter, had been rebuilt. Homeowners received financial support, but renters did not.
As it turns out, it was not entirely the hurricane that cost the lives of 1,500 people, but the fact that the city’s storm levees (technology), which had been built too low and which failed to meet numerous other safety specifications, gave way, flooding the lower portions of the city, occupied almost entirely by African Americans.
Journalist Naomi Klein, in her book The Shock Doctrine: The Rise of Disaster Capitalism, presents a theory of a "triple shock," consisting of an initial disaster, an economic shock that replaces public services with private (for-profit) ones, and a third shock consisting of the intense policing of the remaining public. Klein supports her claim by quoting then-Congressman Richard Baker as saying, "We finally cleaned up public housing in New Orleans. We couldn't do it, but God did." She quotes developer Joseph Canizaro as stating, "I think we have a clean sheet to start again. And with that clean sheet we have some very big opportunities."
One clean sheet was that New Orleans began to replace public schools with charters, breaking the teachers’ union and firing all public school teachers (Mullins 2014). Public housing was seriously reduced and the poor were forced out altogether or into the suburbs far from medical and other facilities (The Advocate 2013). Finally, by relocating African Americans and changing the ratio of African Americans to whites, New Orleans changed its entire demographic makeup.
