What are the thing considered for the sustainable development?

Brief

The present economic level is already unsustainable for future survival. Sustainability is not mean to be kept going and not collapse immediately while drag along as far as it can until it cannot. Sustainability is the rational open process that can connect the closed natural process and bridge us into endless future.

Therefore, the only sustainable development for this economy is the rational order directed manmade and planned negative development.

More explanation:

Fundamentally, we have to adapt the nature given conditions to survive into future, because fundamentally, intelligent life cannot manipulate the nature to get our way ahead wilfully and subjectively. That is because:

We cannot reverse entropy growing process to create material value in this local space and time.

We cannot influence the natural evolution and distribution of material value in local space and time.

We cannot survive and travel in space to access the material value in other local space and time at our present level of existence (unless we can evolve in our nature given conditions for the next giga years to reach that evolution distance to realise that evolution level).

The only thing we can depend on to access future is the evolution level that enable us the fundamentally different existence state to survive that fundamentally different environment conditions of the future while that evolution level is defined by the evolution distance, and this evolution distance is supported by the material value as its material base. But our present way of production and consumption is irreversibly consuming/destroying it that is shortfalling it that will cut short our evolution time to extinct us.

We are locked in this self-destruction process because the natural order is running this social system.

Conclusion:

Therefore the most important thing for sustainability is the change to rational order for our social system.

this is an outline for the decisions that frankie is going to make

opportunity cost

willingness to buy

price or quality

of course, there could be many economic strategies that should be considered important while making decision. opportunity cost is the foremost significant factor while considering any economic option. when you buy something, you should know how much you are forgoing for this product. indeed, you could buy something different with this measure if you changed your mind. willingness to buy shows how much surplus you are earning while making a decision. it is important because it shows you buy what you want or you buy because you have only limited amount of money. the price or quality can be considered as a general economic option that we are applying while buying something. when you buy something, price or quality could be one of the options. indeed, they define the characteristics of the product.
