With man inching out deer’s habitats across the country, deer have become a problem coast to coast by eating shrubs and crops, spreading diseases and causing car accidents. However, the problem goes even deeper. “Fast-multiplying herds are altering the ecology of forests, stripping them of native vegetation and eliminating niches for other wildlife,” writes Andrew Revkin. For the most part, the current methods of controlling deer population -- sharpshooting, trapping, birth-control darts, repellents -- have not been successful. The problem is compounded by the man’s (and children’s) love/hate relationship. “Deer generate more than $10 billion a year in revenue related to wildlife watching and hunting … but they spread Lyme disease and livestock ailments. They are struck by cars, trucks and motorcycles … killing more than 100 people annually and causing more than $1 billion in damage.” “Ultimately, … more hard-nosed intervention, either airmed at stopping reproduction or increasing mortality, will be needed.”
