Roger Hallam, a grassroots organiser, organic farmer and doctoral student of radical direct action organised Extinction Rebellion in the UK with Gail Bradbrook, a molecular biologist and fellow social activist last year.
They felt conventional environmental campaigning based on lobbying and petitioning had failed. The world emitted as much carbon since the early s as in the previous years. Hallam told the New Statesman last week that mass, non-violent civil disobedience is required to confront the environmental crisis, based on three principles: disruption to break laws; willingness to sacrifice in being arrested; and non-violent respect for the public and police.
Hallam comes from the left but is wary of the purist methods on its most radical fringes. He uses three intersecting circles to illustrate his case that in order for the first tiny one of committed and informed activists to make contact with the much wider circle of shocked and concerned citizens it is necessary to bypass or avoid the small left-wing ones also stuck in a political and organisational cul-de-sac. Left-wing environmentalists like the veteran US activist Cory Morningstar respond by criticising how readily movements like Extinction Rebellion and the school students led by Greta Thunberg can be co-opted by celebrity groups seeking to perpetuate a now environmentally unsustainable capitalism.
It is a lively and instructive exchange, now based on a genuine worldwide movement. The dynamics of such movements are illuminated in research by Erica Chenoweth of Harvard university, who has influenced Hallam and fellow XR activists. As important, she shows an average threshold of 3. That would be 11 million in the US, 2. A downward trend in voter participation should cause concern not just to politicians but to advocates of a vibrant, democratic system of government. The French president has a tin ear for the position of central and eastern European states for whom concerns about the Russian threat are very real.

Fact or Fiction?: The Sixth Mass Extinction Can Be Stopped - Scientific American
They calculated that over 40 percent of insect species are threatened with extinction, and each year about one percent is added to the list. This is equivalent, they noted, to "the most massive extinction episode" since the dinosaurs disappeared. The main drivers appeared to be habitat loss and land conversion to intensive agriculture and urbanisation, followed by pollution, mainly from pesticides and fertilisers, invasive species and climate change.

July 1, Insects, which comprise two thirds of all terrestrial species, have been dying off at alarming rates, with disastrous impacts on food chains and habitats, amateur German researchers have found. These butterflies are part of a collection of insects at the Entomology Society in Krefeld, western Germany that its president says is a "treasure trove" of quantitative data. Dutch professor Hans de Kroon uses the German group's data to back up his hypothesis on why the region's bird population is in decline.
The contents of an insect trap underscore Kroon's fears that western Europe could soon reach "a point of no return" in terms of shrinking biodiversity.
Are we heading for a climate apocalypse? Not again
Martin Sorg, head of the volunteer-run Entomology Society Krefeld says: "in western Europe our nature is getting smaller, the agriculture fields are very hostile to insects. Explore further.

Fossil suggests apes, old world monkeys moved in opposite directions from shared ancestor Nov 09, Nov 09, While the PETM pulse of carbon dioxide was rapid in geological terms, it pales in comparison to what humans are doing to the atmosphere. Modern rates of emissions are up to 10 times faster than they were during the PETM.
But whereas PETM emissions were likely the result of a mix of volcanism, wildfires, and methane seeping out of permafrost and the seafloor, the current situation is almost entirely due to carbon emissions from human activity. And those emissions still climbing, with the world setting new high water for carbon pollution last year.
