Blog Bonus Opportunity on Acid DepositionWhat you need to address:

•Describe the composition of a substance that is currently being added to our environment. •Next, biefly explain the risks and benefits associated with this substance. •Finally, present an argument as to how you think we should deal with this substance. •The substance you choose can not be the same as anyone else who has posted a response already. Therefore, you should look over the posts already made to insure you are not duplicating the work of anyone else. •Also, if you want to make a reasonable comment on someone else's posting [in agreement or disagreement] you may do so for an extra point!
