Man is causing changes in temperature and in the bioavailability of resources at a global level and at a frantic pace. The scientific community has already sounded the alarm on several occasions, but governments continue without adopting drastic measures to stop the catastrophe that is approaching us. Our expansion across the planet has caused the destruction and decline of various natural habitats . All this added to pollution and overexploitation of resources translates into a decline in the populations of living beings.
If populations decrease in size, it is not surprising that the genetic diversity within them suffers the same fate, leaving them much more E Commerce Photo Editing vulnerable to environmental variations. The numbers behind the sixth mass extinction... If we take into account that since the pleistocene, the rate of extinction due to natural causes is approximately 0.5 species per year , during the last 500 years around 250 species have disappeared due to causes beyond the control of man. According to a 2014 iucn red list publication , 338 species of terrestrial vertebrates have been declared extinct since the year 1500 of our era.
Subtracting these two figures, we obtain a total of 88 species that have become extinct due to human action (a ratio of 0.18 species per year). If these data do not alarm you, i can tell you in advance that terrestrial vertebrates represent less than 5% of the total fauna of our planet. 90% of the terrestrial fauna is made up of insects and it is estimated that within the same period a total of 653 species have disappeared.
