Environmental health threats: we can adjust daily routine to reduce threats,
your environment is your health – these statements are old -when we realize
everything around us has an impact.
Environment is everything that affects a living organism
Effect of environment on human health is so great – air, water, soil, biota,
manmade environment (created by society), volcano is a physical hazard.
Beside all chemical and physical impacts- some people will be impacted and
others may not be affected.
What is environmental health? According to the who: in its broadest sense,
environmental health comprises those aspects of human health, disease.
According to the Who” This includes the study of both the direct and the indirect
pathological effects of various: chemical, biological, physical, social agents
(housing, urban development, land use, transportation)
Environmental crisis: human alteration of earth. Atmosphere: CO2 increased
30% since the beginning of the industrial revolution, lots of carbon dioxide.
Worries about environments because its in crisis.
Environmental hazards Started off with industrial revolution
Geosphere: 1/3 to ½ of the land surface has been transformed by human action
Biosphere: another part of the environment, clear cutting, forests, trees
Industrialization – great disrupters, pesticide distribution, dioxins.
Overpopulation and overconsumption – affects human health – leads to more
problem in future, actions that can be done, birth rate and death rate and how it
affects human health.
Overconsumption – lots of base and landfills
Health effects of pollution – air pollution, water pollution, soil contamination.
The declining health of other organisms is the clearest indicator of
environmental threats to human health – no single factor is responsible: increase
UV, Traces of toxic chemicals, infections (fungi and bacteria), predators.
Living creatures are in jeopardy.
Climate change –make educated guess. – the number of frogs are declining –
there’s no single fact that can be responsible.
We’re exposed to many chemicals. Environmental health – environmental factors responsible for 25% of all
preventable diseases – in a developing countries diarrhea and respiratory
infections are heading the list
Protecting the environment has been a mainstay of public health practices since
Reach and poor, African Americans and Hispanic- low income and whites [high
income] –income differences. – people with the low income always go for
