Earth 3.0 - Scientific American

This model celebrates the launch of Earth 3.0, a new high quality publication from Scientific American. (www.sciamearth3.com). The model describes what is said in the editor's letter.

Note the use of a separation by Time to describe the three epochs described in the SciAm article. Focus (yellow), Goal (block green) and Risk (block red) have also been used to good effect. Note the use of an 'insufficient counteraction' (dotted crossed line) to denote that early argiculture produced only local impacts, not global harm. Note the use of the 'overloaded' (doubled line) effect to show the industrial consumption. Note the use of 'oppose' (double headed jagged effect) between the concerns about the environment, and the necessary third world development. Note also the use of 'required' (solid circle at source end of effect lines) to signify the necessary actions to bring about the potential (dotted line box) for economic and environmental progress.
