The term "contemporary food paradox" refers to the fact that more than a third of the world's food is currently wasted along the production, distribution and consumption chain, while, in parallel, some eight hundred million people suffer from extreme malnutrition. In addition to the enormous economic loss and the fact that these residues generate detritus and pollute water and soil, the undeniable ethical, environmental and social justice aspects associated with them must be assessed. We first address here the philosophical foundation that revolves around food and environmental justice in relation to aliment waste. From a philosophical point of view, we believe that the global food regime not only violates food justice by failing to ensure the food security to millions of people worldwide, but also constitutes and drives despoil and violates certain minimum requirements of environmental justice. We also describe the preventive policies for such misuse. [ABSTRACT FROM AUTHOR]

In this work, we present the cultural evolution that has allowed to overcome many problems derived from the limitations of the human body. These limitations have been solved by a "cyborization" process that began since early anthropogenesis. Originally, it was envisioned to deal with some diseases, accidents or body malfunctions. Nowadays, augmentations improve common human capabilities; one of the most notable is the increase of brain efficiency by using connections with a computer. A basic social question also addressed is which people will and should have access to these augmentations. Advanced humanoid robots (with human external aspect, artificial intelligence and even emotions) already exist and consequently a number of questions arise. For instance, will robots be considered living organisms? Could they be considered as persons? Will we confer the human status to robots? These questions are discussed. Our conclusions are that the advanced humanoid robots display some actions that may be considered as life-like, yet different to the life associated with living organisms, also, to some extend they could be considered as persons-like, but not humans.

The human being has changed in time due to both biological and cultural evolution. In a first step, biological evolution was the cornerstone of the changes in our species; later cultural evolution provided key adaptations. These adaptations include clothing, tools, reading and writing, calculation and some forms of rudimentary prosthesis. Technoscience has enhanced these adaptations conducing to a broad-sense cyborg. Our contemporary society includes a huge proportion of these latter individuals. In this article we discuss this reality and our future based on the interconnections between humans, cyborgs and robots. [ABSTRACT FROM AUTHOR]
