an emerging problem, you get long cancer and so on. Important in Canada because
we have a lot of granite and shale which have a lot of uranium.
•Climate warming effects: sort of disappearing, was big a few years ago, but there’s
other problems we have to worry about. Part of the problem is we don’t know the
direction of climate change the next 10-20 years.
•Environmental impact of resource extraction and energy supplies: mining,
quarrying, this is a big area now. Biggest one in Canada is in Alberta, oil sands.
Huge amounts of sand that will be removed and treated to get oil out. The resource
industry is creating a lot of jobs in the environmental sector.
•Environmental policy and planning: how should we design urban areas and so on.
•Scope of environmental geosciences: understanding earth processes, providing
resource security, helping society adjust to global change; global change NOT so
much climate change; the way in which the earth is changing naturally, providing
reliable information for planning and environmental decision making; this is very
important, protection from natural hazards, and public health and safety; field
called medical geology, people are beginning to realize that there is a connection
between the geology of our area and our health.
•Slide 3: costs of natural disasters: we can divide natural disasters into what we call
hydrometeorological , geological, and biological (diseases). The United States
experiences the greatest costs from natural hazards because they have a bigger area,
bigger cities, urban areas. Urban areas are more susceptible to risk. In the US,
China, Japan more cost, as urban areas get bigger the more susceptible they are to
hazards, life becomes more dangerous. 80% of all Canadians live in urban areas, the
highest in 81% in Australia.
•Anthropocene: “the epoch of man” the period of earth history that we live in, taken
to begin with the invention of the steam engine, because that was the beginning of
the industrial revolution and demand for resources, factories. Movement of people
from poor paying jobs, to the cities. Urbanization is the number one environmental
issue, though a number of other things stem from this. In this picture we see a built
landscape, built on top of the natural, will produce contaminants that will flow into
•Slide 7: Scarborough Bluffs on the left, just get a blanket of urbanization without
any regard for watershed, we say that we’re doing it better nowadays, but it’s the
