The limitations are not in resources, but in energy

Consequently, if the access to energy is limited, then resources will be limited.

What this mean is that limitations are built into environmentalism. The main premise of environmentalism is that the amount of resources is limited. But resources aren't limited. Here's why. All matter is reusable, provided that sufficient amount of energy is available to break down the chemical bonds that make up most matter. Chemical bonds are far weaker than nuclear bonds within the nucleus of an atom. It is on the order of a million times stronger than chemical bonds. In forcing energy limitations you also impose resource limitations because nuclear energy can be used to recycle materials as long as sufficient energy exists.

Nuclear energy exists naturally from the sun. But it is possible to harness nuclear energy from fission of the atom. The environmentalists are managing to block access to that energy source, which in turn, makes resources limited. If allowed to proceed over the course of time, the sun may break down bonds that are formed which may be harmful to life forms. But not at the rate in which is useful for the type of energy required for modern industrialized societies. Hence, the limitations against energy, in particular nuclear energy ( and fossil fuels as well) will always limit access to all resources. Modern societies require access to resources.

Again, the key to understanding this dynamic is the access to energy. With sufficient energy, all resources can be reused over and over again. That makes resources virtually unlimited, because you cannot wear out an atom. It exists whether in one compound, or in another. Or perhaps in its pure elemental form. The point is that it isn't destroyed. It will always be there, and therefore, be available to use. There is no limitation there. The limitation is in making it useful again. That won't be possible with any other form other than nuclear. The pace of civilization will require a virtually unlimited source of energy, and atomic power can supply than need.

Modern environmentalism must block energy access to achieve their goals. This will have the effect of grinding modern society down to nothing. Without the access to energy, resources will indeed become too scarce to support large populations. All environmentalism is based upon these premises, and therefore, it requires blockage to access to energy for its goals to be reached.

Unless it is not understood that modern enviromentalism is incompatible with advanced civilization, these people will continue to block the advance of society to a higher level.

We are basically stuck at a lower level of development due to this very fact. The GDP of the USA in terms of ounces of gold per person has never advanced beyond the level it was in the late sixties.

There is no limit on resources. Indeed, the limitations are imposed, and completely unnecessary. More to the point, these limitations are quite harmful to human advancement. Without access to abundant energy, the future will be bleak. It makes little sense to block access to energy unless the goal is to cause harm to human advancement.
