Key concepts

Sources of personal ghg emissions in Canada, 2001
My group's key concepts:
-Cause
-Change


Cause:
My group and I, chose connection because we would have to do some more research so we can learn more about climate change and it would be a fun thing to work on. There are many connections for climate change. Like let's say green house gasses. This pie chart shows how many personal contribution in Canada. The Dark green color is how many passangers road and it is 41.0%. The white colored one shows how many People use lightings. It's 2.7%
. I was surprised to see this result. The light green one shows how many space heating they use. The result was 25.7%. The black one shows how many water heating They use. The blue one shows how much they use appliances. The result is 7.9%. The last one, the really small one is for space cooling. The result is 0.7%.




Change:
Many fresh water ecosystem and their services, are unfortunately threatened. The changes humans create on land are mostly environmental pollution. Lets think for example if the services that the ecosystem provides us with are no longer provided, what would we have left to eat? or, what would we have left to drink? Sure we can catch fishes but we are reharvesting fishes. Reharvesting means that the source that we use can regrow but, we use it too much. It will grow the next time but, it will grow lesser and lesser and lesser until there won't be anymore of that source at all! :() ahhhh scary!
