Battling ocean acidification and CO2-related climate change simply requires industrial complexes to wean the world of fossil fuel energy, plus a worldwide campaign to plant billions of trees.

Fields not used to grow food should be planted with trees. All trees that are cut down should be replaced by new saplings.

Buildings shaded by deciduous trees are naturally cooled in the summer and heated in the winter. Buildings that aren’t shaded by trees should have solar panels installed. Industrial parks, shopping malls and parking lots are perfect for solar farms.

Industrial parks are also good candidates for wind-powered energy. Off-the-grid systems in Maine often fully recharge their batteries by midday, proof of economic feasibility.

Several years ago, on-grid homeowners in New York were recouping solar energy investments within seven years. Today, electricity costs more, and solar equipment costs less!

The best time to plant a tree was 20 years ago – the second-best time is now.
