The sixth mass extinction

The Earth stands on the brink of its sixth mass extinction and the fault is ours ... The scientist Vaclav Smil, of the University of Manitoba, has calculated that simply measured by mass, humans now make up a third of land vertebrates, and the animals that we keep to eat – cows, pigs, sheep and so on – make up most of the other two thirds. All the wild animals – elephants, giraffes, tigers and so on – are now less than 5% by mass. It’s a measure of how they have been pushed to the fringes by humans.

One of the scientists who did the study, Anthony D. Barnosky, a Professor in the Department of Integative Biology, Curator in the Museum of Paleontology, and Research Paleoecologist in the Museum of Vertebrate Zoology at the University of California, Berkeley, has advice: 10 Ways You Can Help Stop the Sixth Mass Extinction

As Pope Francis mentioned in his encyclical ...

It is not enough, however, to think of different species merely as potential “resources” to be exploited, while overlooking the fact that they have value in themselves. Each year sees the disappearance of thousands of plant and animal species which we will never know, which our children will never see, because they have been lost for ever. The great majority become extinct for reasons related to human activity. Because of us, thousands of species will no longer give glory to God by their very existence, nor convey their message to us. We have no such right.

I hope people read Barnosky's advice linked to above ... I don't understand why a majority of people just don't care enough to make any efforts to save the plants ans animals of our ecosystem.
