Yes, it is quite interesting if not alarming.

A very, very different view of the living world.

We are such a tiny spec in the whole chain of life.

It redefines biodiversity for me.

Chris Packham warns of 'ecological apocalypse' in Britain

Springwatch presenter says Britain is increasingly ‘a green and unpleasant land’



Birdwatchers have noticed the skies are particularly lacking swifts this year, a summer migrant that is declining at an increasing rate – 51% over 20 years but 25% in the five years to 2015.

Swifts are usually seen in 38% of the bird sightings logged with the British Trust for Ornithology in early June. This year they account for just 31%.

Britain's insects in catastrophic decline

https://www.theguardian.com/environment ... on-decline
Our creepy crawlies may have unsettling looks but they lie at the foot of a wildlife food chain that makes them vitally important to the makeup and nature of the countryside. They are “the little things that run the world” according to the distinguished Harvard biologist Edward O Wilson, who once observed:

“If all humankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed 10,000 years ago. If insects were to vanish, the environment would collapse into chaos.”

Thanks for that, ol.

I was wondering if folks could chime in on what they are seeing in their backyards and regions wrt biodiversity, especially for insects. I feel like I've seen a few more monarchs this year than in previous recent years, but maybe I've just gotten used to seeing so few. But bee populations definitely continue to be lower than they were ten years ago.

How about where you live?

Major reasons for collapse of insect biodiversity in Europe

1) intensive agriculture reducing remnant native habitat
2) agricultural petro chemicals
3) Electric lights at night disrupting reproductive biology of lepidoptera (light pollution)

Basically in Europe we have so efficiently converted native ecosystems over to artificial monoculture landscapes of human ecosystems what else would you expect to happen?

We need to debilitate the human juggernaut.

Imagine all those weeds colonizing one day all that vast mono culture agricultural land. All those larvae feeding once again on a diverse medley of plants. All those beetle grubs once again feeding on fallen deadwood and roots.

In the grand scheme of things Kudzu Ape is a blip on the map. Wont last much longer.

Maybe climate change will be a wedge to get the ball rolling?

Thanks for that link, ol.

The destruction is all around us, but mostly most of us don't see it, or choose not to.

Animals are going extinct 1,000 to 10,000 faster than you’d expect if no humans lived on Earth.

Sixty percent of primate species, our closest relatives on the tree of life, are threatened with extinction.
