week 6 Flashcards
what is eco health?
how environment influences human health and diseases
what is climate change?
any significant long term change in current normal climate conditions
what are some indicators of climate change?
increase in humidity, temp over oceans, sea surface temp, sea levels, temp over land
decrease in glaciers, snow covers, sea ice
what is economic globalization?
rising industrial production, energy extraction, trade, consumption of material goods/energy
what is global warming?
an example of climate change. it is a rise in average global temp
what is a serious impact of climate change?
how climate change will impact water resources bc it is tied to other resources and social issues like food supply, health, industry, transportation, ecosystem integrity
what are greenhouse gases?
gases in Earth’s atmosphere that traps warm air heated by the Sun
what is the greenhouse effect?
GHGs in atmosphere preventing some of the heat from returning directly to space causing a warmer planet
what are the three pollution sources?
point source (pollutants released from a single source), hazardous waste (any waste material that is harmful to the environment and humans), non-point source (diffuse like fertilizers or animal waste or animal operations for food production that contaminated water)
what are the 4 environmental principles?
everything is connected, everything has to go somewhere, impact is proportional to dose, todays solution may become tomorrows problem
how does climate change impact health?
increases malnutrition, increase of disease and injury, changes range of infectious disease vectors, malaria, increase of diarrheal diseases, increase in cardio-respiratory diseases
what are the environmental indicators?
air and climate, water, nature
what is a ecological footprint?
measure of natural resources needed to produce resources we consume and absorb the waste we make
how do droughts impact health?
starvation/malnutrition (water supplies dry, food becomes scarce)
poor hygiene (not having clean fresh water)
water is contaminated
dry weather affects disease-carrying rodents
what are the human factors to climate change?
agriculture, deforestation, habitat fragmentation, sprawl/urbanization, water control
who is at risk of climate change?
women and children, children, elderly, poor
what is environmental racism?
policies that place low-income and POC communities in polluting facilities (like power plants, methane gas pipelines, infrastructure) that leads to greater risk of serious health problems
what are the canadian government agencies involved?
health canada, public health agency of canada, environment canada
what are the provincial government agencies involved?
environment ministry, health ministry, local and regional boards of health
what is the current global situation?
depletions of resources, massive extinction of species, gap between rich and poor is widening, rise in human population
what is environmental justice?
reality that costs of environmental damage will affect certain groups the most and put those groups at greater risk of disease and injury
what are the 4 R’s in environmental pollution?
reduce, reuse, recycle, recover
