This is actually a good idea though this is not really new. I already encountered some projects before dealing with environment and cryptocurrency but sadly they all failed to get the attention of the market, and they just died naturally. Maybe we need a new one, maybe even just focusing on planting fruit-bearing trees will do, we can have more trees to absorb pollution and produce more oxygen, and then we can also have income at the same time. There are many practical ways we can be helping the environment and at the same time make money with the use of cryptocurrency. I am hoping that a good, reputable organization can be carrying a viable project along this line so that we can all participate and be helping the environment in many small ways.
