The World Economic Forum is proposing that we plant 1 trillion trees by 2050 to replace those lost by logging and other means. 1 trillion sounds like a lot of trees, but I suppose that over 30 years and across the world it's not such a daunting job.
I did my bit for the environment at the weekend by planting about 30 saplings in an area of grass. I did similar last year so I can sleep easily on the aeroplane. I have a few more year old saplings coming on, so they will be going into the field in a couple of years. The thing about trees is that the grower rarely sees the benefit, so unless big landowners are incentivised to plant them, it will rely on small scale planters like me plus the odd rich landowner who is a bit concerned about the planet.
However, I planted a row of lime trees down my drive about 25 years ago and they look great in spring and summer so you can get benefits in a lifetime (if you live long enough).
p.s. just did a quick calculation on the trillion trees - that's 63 per minute over 30 years. I had better get digging.
