2. Do Now:
Read over the San Diego and Tijuana Case study on p in your book and answer the following:
1. List the problems in San Diego and Tijuana
2. Why do these problems exist?
3. Can you suggest a solution (or you may be aware of one)?

3. Tijuana River Watershed
Figure 5.1 The Tijuana River winds northwestward from Mexico into California just south of San Diego, draining 4,500 km2 (1,750 mi2) of land in its watershed (colored green in map) (a). Pollution entering the river affects people on both sides of the border and sometimes creates a visible brown plume of wastewater entering the Pacific Ocean (b). The photo shows an aerial view from the north, with Tijuana in the background.

5. Central Case Study: San Diego and Tijuana
Rain washes pollutants into Mexico’s Tijuana River
Then onto U.S and Mexican beaches
A new sewage treatment facility reached capacity
In 3 years
Poor Mexicans suffer most
Contaminated water, disease, industrial waste

6. We can develop sustainably
Environmental degradation affects the poor the most
Sustainability is more than protecting the environment
Sustainability means promoting social justice, economic well-being, and environmental quality at the same time

7. Seven steps to making environmental policy
Theoretically, in the U.S., everyone has a voice and can make a difference
But money wields influence
Some people and organizations are more influential than others
Creating environmental policy has several steps
Requires initiative, dedication, and the support of many people
