EESA – Lecture 1:
Environment affects our health. Also other factors that influence our health (such as genetic
traits from mother, father, grandparents and etc.) For example, one person may be resistant to
disease more than another person. – This won’t be spoken about much in lecture.
What is environmental health? (1)
Disease and injuries.
Factors: (2)
Chemical – organic/inorganic that we come into contact with.
Physical – everything around us.
Social environment
- Housing: what type of house we live in (old, with lead pipes – means we will have lead in
our drinking water).
- Urban development: rural/urban areas or developing/developed areas.
- Land use: agricultural land, urban parts.
- Transportation
What is the environment?
Everything.
Everything that affects the living organism (wolf, type of bird, plant, oak tree and etc)
Mostly air, water, soil are the compartments that are part of our general environment. Also,
manmade environment (everything that is human work; buildings, roads).
Environmental Health
Humans change this climate very significantly.
Human altered the forests, lakes, rivers, the North, and etc.
1/3 or ½, or 80% of the Earth’s surface is already altered that it will probably never be the
same again.
2 major reasons why humans do this and why it’s getting so fast is b/c:
- change in the human population (the sig. Growth of individuals on growth (exponential
growth of number of ppl on earth).
- Also, 2
nd
reason is consumption; we want more goods to make our life more comfortable
(luxury), shopping and etc.
We have no idea how to stop it or slow it down.
This worry isn’t really that recent.
Main idea since 1978 is to protect the environment. In some areas there is results but will be
spoken about later.
Most environmental diseases are preventable.
Environmental factors are responsible for about 25% of all preventable diseases. Best ex, are
diarrhea and intestinal infections. Maybe not in Canada but in most developing countries.
