“According to the National Parks and Conservation Association study in 2006 each federal dollar invested in national parks generates at least four dollars of economic value to the public. National parks are responsible for $13.3 billion dollars of local, private-sector economic activity nationwide, supporting 267,000 private-sector jobs. Outdoor recreation alone generates $646 billion in consumer spending and 6.1 million direct jobs in the United States each year, according to the Outdoor Industry Association.”
