Biodiversity in Change – Global Patterns of Biodiversity:
Life is the single unique feature of our planet. Around 1.5 million species have been described by science; extrapolations indicate that there are between 5 and over 100 million species on our planet. Global spatial distribution patterns of species and their changes are presented.
It is apparent that in the Anthropocene we face the beginning of an extinction crisis on a geological scale, a consequence of the exponential global population growth and the »growth philosophy« behind it.
This directly results in extensive destruction of natural habitats, pollution and global warming. Evolution is almost of no importance for these biodiversity changes, but rather the migration of invasive species.
This temporarily increases the diversity for a geographically limited area: today Germany presumably has the highest biodiversity than ever before in historical times. Globalization leads to a short-term regional increase of diversity, but inevitably in the long term to a standardization and reduction in diversity at the global level.
This is not a fundamental threat to our livelihoods – only their quality. There seems to be no escape from the main problem (population growth). Scientist can only deliver data and recommendations; society, education, politics and ideologies (incl. religion) determine what kind of world we will live in.
