Society is increasingly more aware of the detrimental impacts which biodiversity loss can cause on human well-being (Collen 2013). Biodiversity has a direct influence on those ecosystem structures and functions which affect our food supply security, spreading of contagious diseases, pollination, genetic resources for the pharmaceutical industry etc. (Collen 2013). For this reason, academics and policy makers' focus has shifted more and more towards developing a comprehensive methodology to allow a correct monitoring of biodiversity indicators as well as indicators of pressure in order to derive a better understanding of the causality of biodiversity loss (Collen 2013). Moreover, this can lead to a reconciliation of the current gap between global and national policy implementation leading to a more holistic approach (Collen 2013). Biodiversity loss differs in specific regions of the world. Notwithstanding the difficulties in measurements outlined above, the main driver of such diffe...

Biodiversity loss and with it extinctions of species are the main factors reshaping key processes in Earth's ecosystems which directly impact its related services such as water or food supply (Hooper 2012). In order to introduce just and effective policies it is important to understand the anthropogenic drivers of such phenomenon (Jaureguiberry 2022). Land use and farm land expansion is the main direct cause driving around 30% of biodiversity loss globally (The Royal Society). Overexploitation of natural resources is the second one followed by climate change, pollution and invasive alien species (Jaureguiberry  2022). Such ranking varies whether we're talking about human driven impacts on land or ocean ecosystems (Jaureguiberry  2022). The Sixth Mass Extinction, also called Holocene Extinction, is characterized by mostly human induced factors oppositely to the older mass extinction which were driven by natural causes (Ceballos 2015). Because of anthropogenic impact as well as ...

Already in Ancient Greece men pondered on the idea of evolution by questioning the origins of the human species (National Geographic). The ancient philosopher Anaximader reflected on the idea of evolution by observing human beings which, helpless at birth, must have originally derived from a more self sufficient species able to survive with no help  since childhood, such as fishes (National Geographic). However, the most scientific idea of theory of evolution came only much later with Charles Darwin and Alfred Russel Wallace in 1859 (National Geographic). This because of the intrinsic definition of "theory" which can be used to describe a scientific explanation only after rigorous testing through observations and experiments (National Geographic).  The idea behind this theory is that evolution occurs by natural selection, where the "fittest" that survive the environmental changes are those which traits are more prompt to such conditions (Darwin 1859). Nowadays, rese...
