Reminders:

• Loss of land plants because of human activities will not result in a reduction of atmospheric oxygen because most of planetary photosynthesis and its resulting oxygen production is in the oceans.
• Be sure to back up your explanations with some research before discussing this topic online with your classmates. Be sure to read relevant sections of your text (and supplementary readings from this Module) and look online.  Start with the links in this question and the Resources listed for this Module.
