Awwww i'm stuck!
I keep getting bad marks, yet in class i seem to understand everything, just not sure exactly how to answer questions...
Well i have a report due where i need to "assess the effectiveness of steps taken to alleviate the problem of ozone depletion". Anyone have any idea as to how i should attack this question? What i should mention, any ideas that may help me get started?
I'm totally stuck, anything is very much a help
Thankyou guys!


Goodluck with your HSCs!

Talk about CFC's and explain why they are bad to the ozone layer.

Then talk about what has been done to restrict the amount of CFC's liberated into the atmosphere.

1. montreal treaty:
*replacing CFCs with HCFC or HFC
*helping developing nations phase out the production of CFCs
2. HCFC: breakdown in the troposphere
3. HFCs: no clorine
^ steps taken
need to assess how effective it is
