Most sites I check, about becoming carbon neutral, suggest a number of trees I must plant to offset my carbon usage. I have grandchildren, who are far too impatient to watch a tree grow. Sunflowers, being annual, are great to grow, with fairly instant results for them to look at. I would like to know if anyone knows how many must be grown to offset 1 ton of carbon dioxide - though I appreciate it would be a huge number!
