Human impact…
What is your ecological footprint? What are some things you can do to
improve your ecological footprint? Why should we care? How does the information from each of
the quizes compare?

How does our footprint (canadians) compare to other countries? What ‘s the difference between the countries i.e. what makes it worse or better?

Biodiversity within Ecosystems
Biodiversity of an ecosystem is the measurement of the number of species within that ecosystem.
It involves the dynamic abilities of species to adapt to and survive in an ever changing world.
There are presently over 10 million different species on Earth.

Each member of an ecosystem is a valuable participant in the stability of that area.
All organisms have a niche, or role to play within that ecosystem. Whether they are predators, prey, producers or decomposers, their position is valuable to the sustainability of the region.
