I do wonder whether there will come a time when we can no longer afford our wastefulness - chemical wastes in rivers, metal wastes everywhere, and atomic wastes buried deep in the earth or sunk in the sea."
	- John Steinbeck

	"In an era when a chemical spill can kill thousands, when wastes buried 20 years earlier can contaminate community water supplies, when our environmental ignorance can plant the seeds for later diseases, environmentalists and industrialists cannot continue to draw false battlelines."
	- Jay Hair
