Human activities have important impacts on all natural systems of the planet and several of these impacts cannot be reversed. For example, we divert rivers, use the power of waterfalls, extract metals and minerals from the ground, clear and cultivate the lands. Once these modifications have been made, and natural habitat and species lost, they cannot often be reversed.
A clean and healthy environment is vital for humankind. To better evaluate and minimize population impacts on the environment, it is necessary to study the distribution and the variation of population within ecological areas such as ecoprovinces. An ecoprovince is a natural area which is characterized by its relief, its fauna and flora, its soils, its hydrography and its climate. Canada encompasses 45 ecoprovinces. The more people in an ecoprovince, the higher the chance of loss
of habitat and species.
