Jobs in Environmental Cleanup and Emergency Hazmat Response [PDF ebook] 

When the environment suffers, so do humans and wildlife. Many green jobs require only high school or one or two years of post-high school studies. For other jobs, special training or four-year or postgraduate degrees are required. Some of the careers that are examined in this enlightening book include environmental engineer, geologist, microbiologist, science technician, conservationist, forester, park ranger, soil scientist, air control technician, toxicologist, dredge operator, ecologist, hazardous waste manager, and zoologist. For young people willing to commit to such work, for the sake of the planet, career paths are numerous, expanding, and exciting.
