The Environment

Environmental problems cannot be fully understood without appreciating their social context. In this regard, we discussed two major emphases of environmental sociology. First, environmental problems are largely the result of human decision making and activity and thus preventable. Second, environmental problems disproportionately affect the poor and people of color.

These two insights have important implications for how to improve our environment. Simply put, we must change the behaviors and decisions of individuals, businesses, and other organizations that harm the environment, and we must do everything possible to lessen the extra environmental harm that the poor and people of color experience. Many environmental scholars and activists believe that these efforts need to focus on the corporations whose industrial activities are often so damaging to the air, water, and land.

Beyond these general approaches to improving the environment, there are many strategies and policies that the United States and other nations could and should undertake to help the environment. Although a full discussion of these lies beyond the scope of this chapter, environmental experts recommend a number of actions for the United States to undertake (Lever-Tracy, 2011; Madrid, 2010; McNall, 2011). ^[1] These include the following:

1. 
   Establish mandatory electricity and natural gas reduction targets for utilities.
   
2. 
   Expand renewable energy (wind and sun) by setting a national standard of 25 percent of energy to come from renewable sources by 2025.
   
3. 
   Reduce deforestation by increasing the use of sustainable building materials and passing legislation to protect forests.
   
4. 
   Reduce the use of fossil fuels by several measures, including higher fuel economy standards for motor vehicles, closing down older coal-fired power plants, and establishing a cap-and-trade system involving large payments by companies for carbon emissions to encourage them to reduce these emissions.
   
5. 
   In cities, increase mass transit and develop more bicycle lanes and develop more efficient ways of using electricity and water.
   

Another strategy is perhaps delightfully simple: turn rooftops and paved surfaces white! In many US cities, roofs of houses, high-rises, and other buildings are covered with dark asphalt shingles. Dark surfaces trap heat from the sun and promote higher air temperatures. Painting roofs white or using white shingles to reflect the sun’s heat would reduce these temperatures and help offset the effects of global warming (Levinson et al., 2010; Lomborg, 2010). ^[2] A similar offset would occur from changing the color of our streets. Many roads in cities and other areas are composed of dark asphalt; using a lighter material would also help reduce air temperature and counter global warming. If these measures reduced air temperature in warm cities, less air conditioning would be needed. In turn, electricity use and carbon dioxide emissions would also decline.

To repeat what was said at the outset of this chapter, it is no exaggeration to say that the fate of our planet depends on the successful implementation of these and other strategies and policies. Because, as sociology emphasizes, the environmental problems that confront the world are the result of human activity, changes in human activity are necessary to save the environment.
