Answer:
Two of the main criticisms towards the theory of sustainability are: 1. That humans tend to deplete the land of resources without a care for what the future will bring, and 2. That Earth´s resources do not have a limitation in the face of human activities, resources will not, and do not, become scarce, and that the definition of what a resource really is changes continually.
Explanation:
Sustainability is the belief that humanity has to consider Earth´s renewable and non-renewable resources to order its society, its economic activities and the use of the environment for the present and future generations. It is based on those three precise pillars: the environment, society and the economy, and it seeks to organize, and control, human activity on the environment, so that resources may be wisely used and thus become available for future generations. However, despite the wide acceptance of this theory, there are also criticism to it. One is the view of humans almost like viruses that just move, deplete, and then move again, and the second, the disbelief that resources can be finished on Earth, and truly defining what a resource is, and whether it is renewable, or non-renewable.
