Question

1. which sequence of events can be correctly cited with the map above? (teks 21c)

a. existing crude oil reserves deplete, the oil sands have become an important energy resource, deforestation increases in the boreal forest as the active mining footprint increases.
b. deforestation occurs in the boreal forest, the oil sands mineable area increase. crude oil dependence decreases
c. water pollution occurs in the hudson bay, environmental activists protest the destruction of the ecosystem, the government creates policies to protect the hudson bay, the active mining footprint decreases
d oil sands mineable area increases, oil sands extraction increases, pollution decreases, the boreal forest is protected

Explanation:

• When existing crude oil reserves deplete (a common resource - depletion scenario), oil sands (shown on the map) become more important as an energy resource.
• As mining (active mining footprint) for oil sands (part of the oil - sands area) increases, it is logical that deforestation (since the oil - sands area is within the Boreal Forest region as per the map) in the Boreal Forest would increase.
• For option B: There is no clear indication from the map that deforestation causes an increase in the mineable area. Usually, the need for resources (like oil from oil sands) drives the expansion of mineable areas, not the other way around.
• For option C: The map does not show any direct connection between water pollution in Hudson Bay and the elements related to the oil - sands and Boreal - Forest areas (active mining footprint, etc.).
• For option D: An increase in oil - sands extraction (due to increased mineable area) is more likely to lead to more environmental impacts (like potential pollution, not a decrease) and less protection of the Boreal Forest (as mining expands into it), which is contrary to what is stated in this option.

Answer:

A. Existing crude oil reserves deplete, the oil sands have become an important energy resource, deforestation increases in the Boreal Forest as the active mining footprint increases.
