Trees of life

Re “It’s a tidy answer to global warming,” April 29

Scientists’ efforts to find technological solutions to remove carbon dioxide from our atmosphere are admirable, even if they require massive amounts of electricity.

But Mother Nature long ago provided us with free devices that remove carbon dioxide from our air using natural solar power: trees and forests. One fast-growing tree can sequester many tons of carbon.

In addition to curtailing carbon emissions, let’s get back to basics. How about planting trees?
