Modern society is increasingly aware that humans and culture are components of the natural environment,and that human health is inextricably linked with environmental condition.Therefore,it is useful to explore methods and patterns of human settlement and landscape modification for their potential adverse effects on human as well as environmental health.The fields of landscape ecology and landscape architecture,among others,have generated a rich literature on the environmental consequences ofurban land use.By comparison,research and discussion are highly limited on the related issue of human effects.
The population of the United States of America(USA) is currently experiencing illness and mortality from a broad range of insults that have not traditionally posed significant public health threats here.The epidemics of today include asthma and allergies,animal-transmitted diseases,obesity,diabetes,heart disease,depression and other mental illnesses,and suicide.It is true that scientific advances have alleviated morbidity and mortality from many infectious diseases and injuries.Historic efforts to regulate public sanitation,factory emissions,workplace safety,food production,and other centralized activities have reduced the health risks of industrial and municipal origin.Many of these controls have also benefited environmental condition.In the most well-known cases,reduction or elimination of toxins has restored river biota and top avian predators.However,the natural environment remains very much under siege,suffering habitat loss and fragmentation,invasion of aggressive exotic competitors,and continued pollution despite the regulatory framework.Meanwhile,the human population exhibits signs of malaise,sickness,and even death from what appear to be dispersed,synergistic ambient causes.
