ok but you did not really say why this is a prob overall, yeah mention the ozone shield thing. why is it bad if holes appear? ok it causes cancer etc. but WHY?Originally posted by abdooooo!!!
i went through my trial CSSA few times and found i lost so many marks for some weird reasons.
For example:
Discuss problems associated with the uses of CFC's (2 marks)
"The use of CFCs causes the thining of ozone layer in the stratosphere, and in some cases it makes holes appear. This leads to the increase in the amount of u.v. light reaching the earth surface and has resulted in an increase risk of cancers in living organisms."
