In short words:
The prices of timber is growing from year to year (you can ask Teodor to have more details), so planting the wood is a good but long term investment. Hard and rare timber, like mahogany, is expensive. It's a good business to plant other trees like oak or pine tree (in eastern Europe there're thousands of hectares of it, being planted, after some years cut and sold). Some of them - rare and hard - are really good investment. This is one branch of trees & trade - Investment Trees.
Second branch is trees 4 bees. It is a bit different, because it concerns only the trees that are pollinator-friendly, so it combines investment with ecology support. As you know, we have a bee disaster because of pesticides used all around the world for the last 50 years and monocultures of certain plants. We have to support the bee population (and all the pollinators populations), because if we don't, we won't have fruit or rapeseed anymore (pollinating is necessary for those plants). This is how the nature regulates itself. The species in this branch would be eg. accacia, lime, maple - the trees that support pollinator by feeding them and letting them make home (therefore they rebuild their natural population). According to scientists I've talked with, even a small (several dozen trees) plantation makes a big difference to a local ecosystem (e.g. a county). Those trees after cut they are used for several things from furniture to guitars.
Trees24 is an upcoming website, where you'll be able to buy or sell the trees online during they grow - something like stock trading of corn, soy or wheat that is still growing somewhere on the farm. The trees will have their "time-to-cut" fixed, so after certain time their valid owners will be able to monetize them (or wait some more time and let them grow bigger and therefore to enlarge their profit). I think that trading online will make a very good profit for you personally if you buy some trees and wait a bit, because there're a lot of people who want to support the ecology and they would learn about cryptocoins, try them and buy the trees4bees to be more eco-trendy. Ecology is trendy, and this is the way for all the crypto community to popularise the coins.
If you wish, I can send you more detailed description and draft plan.
