Analyses of recently-emerging infectious
diseases show that anthropogenic factors
including land use change (e.g. deforestation,
mining, oil extraction, etc.), food production
changes, and global trade and travel are among
the leading causes of disease emergence
The consequences of human actions on risks for infectious diseases: a review
Globalization's environmental and climate effects have also heightened some infectious disease threats. Deforestation, for example, has increased the threat of dengue fever and other mosquito-borne diseases in tropical areas. When animals are forced from their habitats and into residential areas, the insects that feed on them follow, increasing the opportunities for pathogens to infect the nearby human population.
Natural and Ecological Hazards. Very informative and comprehensive
How climate change is increasing the spread of infectious diseases
WHO
According to the United Nations International Strategy for Disaster Reduction (UNISDR), a hazard is a natural process or phenomenon that may pose negative impacts on the economy, society, and ecology, including both natural factors and human factors that are associated with the natural ones
Natural and Ecological Hazards. Very informative and comprehensive
Health geography is a broad and fast-developing field of public health that incorporates the information and methods of geography to study how both health and disease relate to the environment. The field is also known as medical geography. Most activities in health geography fall into one of three areas: disease ecology, healthcare delivery, or environmental health. In each case, scientists use geographic analysis and often its accompanying technologies to provide insights into health and disease.
Categories of environmental health hazards
Hazards are generally categorised as follows:
Physical hazards
Biological hazards
Chemical hazards
Cultural/practice-related hazards
Social hazards
Coronavirus is a wake-up call our war with the environment is leading to pandemics.
