70
Q

What is Toronto’s main watershed. What is Toronto’s sub-watershed.

A

Main Watershed: Great Lakes Watershed. Sub-Watershed: Lake Ontario and Niagara falls

71
Q

What is the rating of pollution in our watershed? Why?

A

Rating: Very High. Because Toronto is one of Canada’s largest city that creates a lot of pollution.

72
Q

What is the rating of Habitat Loss in of watershed? Why?

A

Rating: Moderate. Because there are so much infrastructure in this area which is destroying habitats

73
Q

What is the rating of Overuse of Water in our Watershed? Why?

A

Rating: Very High. Bedause there are so many people on this watershed using too much water.

74
Q

What is our watersheds rating of Habitat fragmentation? Why?

A

Rating: Very High. Because of more roads, railroads, and dams.

75
Q

What is our watersheds rating of Invasive species? Why?

A

Rating: Very High. Because of more marine shipping bringing in more things on their hulls, like zebra mussels.

76
Q

What is our watersheds rating on Climate Change? Why?

A

Rating: Moderate. Because there haven’t been many drastic changes to our water shed because of climate change.

77
Q

What is our watershed rating on Alteration of flows? Why?

A

Rating: Moderate. Because of more damming in the watershed.
