You're right, they'll all be underwater because their forefathers exacerbated climate change and car-dependent suburban sprawl by prioritizing a few urban trees over thousands of rural ones.

Kudos to Johnson for taking this on and trying to find the balance between our moral obligation to our children to add housing that promotes low-carbon living and the need to maintain (not add, that's an absurd goal to set) green space in our cities. Unfortunately there's quite a few "tree advocates" in this city that are not bargaining in good faith and are using tree retention is a useful Trojan horse for their real agenda - making sure it's still easy to park cars on the public Right of Way in their neighborhood.
