Crosmary, Cote, and Fritz analyze the benefits and complications of trophy hunting in their publication, "Evaluating the Role of Trophy Hunting in Wildlife Conservation." A concern expressed in this article is that the paper recognizes that the costs of land protection for wildlife can be crippling to governments and local communities due to competition between land use options such as agriculture or urban development . Funds provided by trophy hunting provide an economic incentive for governments and local community members to support wildlife conservation. There are 23 African countries that allow trophy hunting within their borders, generating $201 million per year in sub-Saharan Africa alone. To accommodate 18,500 international hunting customers, 1.4 million square kilometers of land has been set aside for trophy hunting in sub-Saharan Africa. The largest trophy hunting industry is South Africa, which generates $100 million a year and is still growing. In addition to providing less income than trophy hunting, tourism often leads to greater use of fossil fuels. When tourists visit they often want comfortable living conditions and expect conditions similar to those at home, this requires fuel for vehicles, light sources, air conditioning and heating and others
