So far, „sky“ is pretty nice

It’s an investment? Just like an office building or a company car?

Depends. Is it stable? Does it pose a threat to passer bys ?

I‘d have to get my tables from work. It highly depends on the species, soil, size, location, age, natural area of the species and so forth. A decently sized oak at around 100-150 years old usually gets weighed in at around 2000€. Variation however is a given.

Trees prevent soil erosion, keep water clean, provide the basis for many beneficial insects and so forth and so on. They have a giant value in our financial system.

All of these views are valid. A tree has to be seen for what it can provide. If it’s more valuable to society and nature as a tree, leave it be. If other trees can gain from it being removed earlier than its natural decay demands, I’d argue to remove it.

Dogs would be a good example for ring species, which show the outer limits of the species definition, if they they occurred in the wild in their many diverse forms. But since they are not, I’d group them as one species still, as their origin is artificial and so are, at least partly, their means of reproduction.

In theory: yes, most likely. In practice? No.

Usually you’d go to the bank with the project and they ask you for securities, oftentimes the house your building or the ability to garnish your wages. Also they demand to know how much you’ve saved so far. Can’t give loans to everyone?

Why not? The concept is fairly easy to grasp and if I want a loan for a house, the bank can ask me to prove that I was able to put aside enough money beforehand to be able to chip away at a credit from now on.

And rightfully so. That movie was an utter atrocity.
