The Anthropocene Biosphere

Humans are transforming Earth in absolutely unprecedented ways.

A study shows how homo sapiens has radically changed their natural home, planet Earth and has "caused shifts in world ecosystems unprecedented in the last 500 million years." (source)

• Similar to the Great Oxygenation Events 2.3 billion years ago, human impact has produced a new kind of biosphere.
• Intervention in the diversity of life has been the greatest for the past half billion years.
• Our only home, planet Earth is entering a new kind of planetary state

Some of the key changes are:

•         "The homogenisation of species around the world through mass, human-instigated species invasions – nothing on this global scale has happened before

•         One species, Homo sapiens, is now in effect the top predator on land and in the sea, and has commandeered for its use over a quarter of global biological productivity.  There has never been a single species of such reach and power previously

There is growing direction of evolution of other species by Homo sapiens

•         There is growing interaction of the biosphere with the ‘technosphere’ – a concept pioneered by one of the team members, Professor Peter Haff of Duke University - the sum total of all human-made manufactured machines and objects, and the systems that control them" (source)

Afterthoughts:
The global homogenisation of flora and fauna is obvious. People support a world full of poodles and horticultural weeds. They do not appreciate the endemic biodiversity of the place they dwell in. The eradication of bio-diversity is replaced with a monoculture.

Only one species (Homo sapiens) grabs 40% of net primary production

Burning fossil fuels and biomass seems an unstoppable addictive behaviour. We would rather burn to death, than modify our way of life.

Humans dictate the evolution of all other species, also having a go at their own imperfections.

We are constructing a gestell/ artifact that "could persist over geological timescales, an interaction of the biosphere with the technosphere (the global emergent system that includes humans, technological artefacts, and associated social and technological networks)." (source)

This noosphere (mind sphere) or a distributed agency seeks to expand the domination of space as well as planet Earth.

Spaceship Earth is fully in the hands and the code of the human helmsman. While vandalising the cradle of humanity and depriving the rest of life of a habitable planet, man steers for the goal of more and more.
