First off you are growing trees – what is being planted are seeds or saplings.
2 billion sounds a lot. but any competent planter can do over 1000 in an hour
(…the world record is 15 000 – but let’s go with the 1k)
So that’s employing one person for one hour 1000 trees planted.
Employing just 300 people – that’s 300k trees – in one hour.
If those 300 folk work a seven hour day. That’s 2.1million trees. In 1 day.
If they work a five day week. That’s 10.5 million trees in a week.
If they only plant trees for 30 weeks a year. That’s 315 million trees in a year.
So employing just 300 people – delivers over 15% of the target in a year.
…and it’s a twenty year target.
Oh and if you are wondering where there would be space for them all – the entirety takes up just a little bit more 2.7% of land mass than the amount of ground currently covered by golf courses (2.5%).
This is like Labour’s other policies – reasonable, doable, and necessary.
