...Cancer spreads throughout the world because we release chemicals into the water, air and soil. The chemicals we spray on our crops contaminate our ground - water, while acid rain pollutes our freshwater supplies. Worse, First World countries use dyes, preservatives and other chemical additives in every facet of food production. We cause our own deaths with the poisons we inject into our food.

...visas. As much as I support the concept of brain drain—it’s such an extravagance to send those we educate back to their countries of origin, to waste their education among non-American peoples—the very presence of foreigners on our soil (especially that of the wild Canadian hordes) makes my skin crawl. And there’s only one thing that makes my skin stop crawling—apple pie, just like my mom makes (my mom, who is American?...

...things are getting worse. The water quality of the Yangtze's tributaries is deteriorating rapidly, as the dammed river is less able to disperse pollutants effectively. The incidence of algae blooms has risen steadily since the reservoir was completed in 2006. The rising water is also causing rampant soil erosion, resulting in riverbank collapses and landslides along the shores of the Yangtze's tributaries. Professor Lei Hengshun, an environmentalist at Chongqing University who has devoted years to studying and preserving the Three Gorges ecosystem, says that if the water level of the reservoir reaches its planned height of 165 meters...
...process is a no-brainer. Corrosion happens as a result of a pipeline throwing off a naturally occurring electrical charge. But cathodic protection creates a countercurrent, which flows from an anode placed near the pipeline, through the soil and directly onto the pipeline itself, effectively zapping the initial corrosion-making charge. As long as the new force field is operational, corrosion can be kept at bay indefinitely. That's good news. In 2002 a congressionally mandated study, titled "Corrosion Costs and Preventive Strategies in the United States," estimated that the annual cost of corrosion on large-diameter highpressure pipelines...
