I have been donating some money every month to an Icelandic tree planting project to offset my carbon emissions after reading an article on HN about how the Vikings cut all trees of the island. I find the numbers fascinating :

> Forests and bushes now cover over 2% of Iceland, Vísir reports. That number may not seem like much, but since 1990, the surface area covered by forest or shrubs in Iceland has increased more than six times over – from 7,000 hectares to 45,000. In 20 years, the number is expected to be 2.6%.

And from another article :

> The Forest Service intends to deliver six million plants this year, says Þröstur, which is equivalent to pre-crash levels of production. “It was around five million last year, and four million the year before that. This is a rapid increase. Then we need seven to eight million next year, which we may not manage, and ten to twelve in 2025.”
