Message:

keeping in mind  issues such as water pollution and ourdwindling 
forests, are our oceans and forests abilities to produce oxygen 
being compromised ? 
Could there be a critical threshold beyond which life could not 
be supported ?
Does pollution lessen the oceans ability to create oxygen?
