"There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved."

Anthropocene, Eremocene, and Biodiversity loss (VII).
We humans are predators. We target more than a third of the vertebrate species. Pet trading, medicine, and other uses now affect almost as many species as those targeted for food, and we threaten almost 40% of exploited species.

Biodiversity loss (VI). We waste too much food
According to the World Wildlife Fund (WWF) we waste up to a third of the food produced. Only in the European Union (EU), with about 450 million inhabitants, eighty-eight million tons of food end up in garbage dumps every year. That is close to 200 kg of food per inhabitant.

New Zealand—antipodal of Spain—with 4.5 million people, has fifty million sheep, more than ten sheep for every human. The municipality of Lorca, in Spain, has about 96,000 inhabitants and one million pigs.

Lands, Seas, and Biodiversity (IV)
More than 50% of humanity already lives in cities. In China, this figure reached 67% in 2024. This fact, together with the slowing rate of global population increase, could represent an opportunity for the recovery of a part of the planet's surface to a state like its original condition, prior to human transformation of the land.

Ecological serial killers and Biodiversity loss (III).
Yuval Noah Harari, in his book Sapiens: A brief History of Mankind, coined the term "ecological serial killer" to describe our image in the eyes of other living beings. Since the departure of our species from Africa, this image has not improved—quite the opposite.

Biodiversity loss (II), Homo Sapiens: an invasive species
Each extinct species because of human action, including those that we will never know about, is associated with a cost impossible to calculate. I refer both to the moral damage and the economic cost. Scientists discover around 20,000 new species every year, but they still expect to discover about 85% of the world’s animal species.

Joan Baez, Connie Francis, and Biodiversity Loss (I)
We function as if resources were inexhaustible and there was no impact in dumping waste under the carpet of the surface of the land and sea, into the air, and even into space, which far from becoming the final frontier can become the most recent garbage dump.

Climate Emergency (X): Future
David Attenborough and many scientists tell us that we have already surpassed the threshold of planetary stability in four areas: 1) climate change; 2) fertilizer use; 3) land conversion; and 4) biodiversity loss.

Climate Emergency (VI): Ice disappears and sea level rises
The Northeast Passage winter navigation could allow an increase of Russia’s exported natural gas from thirty-two million tons in 2020 to eighty million in 2024, and to 130 million in 2035—precisely what the environmental doctors ordered, and the planet needs.

Climate Emergency: Why? - Emergencia climática: ¿Por qué?
Seventy thousand years ago Homo sapiens was still an insignificant animal minding its own business in a corner of Africa. In the following millennia it transformed itself into the master of the entire planet and the terror of the ecosystem (Yuval N. Harari.)

Evolution carries on (III), Overpopulation, and Fertility
