Human over-consumption causes far more biodiversity loss than climate change

Human over-consumption causes far more biodiversity loss than climate change

Preface.  Human ancestors began reducing biodiversity 4 million years ago, when large carnivores in Africa began disappearing, probably due to our ancestors stealing food predators had caught, starving them to death and eventually driving some of them extinct (Faurby, S., et al. 2020. Brain expansion in early hominins predicts carnivore extinctions in East Africa. Ecology Letters.)

2016-8-13. Climate change isn’t the biggest danger to Earth’s wildlife, our thirst for natural resources is even more damaging

2016-8-10 “Biodiversity: The ravages of guns, nets, and bulldozers” Nature)

Even though climate change is going to have a very powerful impact on plants and wildlife world-wide, climate change has also become a scape-goat, with a “growing tendency for media reports about threats to biodiversity to focus on climate change.”

But scientists have found that over-exploitation, including logging, hunting, fishing and the gathering of plants is the biggest single killer of biodiversity, directly impacting 72% of the 8,688 species listed as threatened or near-threatened by the IUCN. Agricultural activity comes second, affecting 62% of those species, followed by urban development at 35% and pollution at 22%.  Species such as the African cheetah and Asia’s hairy-noes otter are among the 5,407 species that find themselves threatened by agricultural practices, while illegal hunting impacts several populations such as the Sumatran rhino and African elephant.

Climate change on the other hand comes in on a surprising, if somewhat unimpressive, 7th place in the 11 threats identified by the team. Even when you combine all its effects, it currently threatens just 19% of the species on the list, the team reports. Species such as the hooded seal, which the team reports has seen a population decline of 90% in the northeastern Atlantic Arctic over the past few decades as a result of declining ice cover, are part of the 1,688 species directly impacted by climate change.

How learning to share again cuts waste, and makes more resilient communities

How learning to share again cuts waste, and makes more resilient communities 

 See lessons

Sharing is one of the very first things we are taught to do as children, it’s almost the defining difference between being ‘good’ or seen as selfish. But from the moment we become adults the focus quickly shifts in modern economies to everyone having their own things and protecting ‘private property’. Not only does this exclude people with little money, it leads to a lot of environmentally wasteful over-consumption as households duplicate often underused items. If we shared more in modern life it could cut waste and bring us together. Now a movement is emerging to rediscover the benefits of sharing.

The Share Shed is a library of things in the town of Totnes in the southwest of the UK (also home to the Transition Town network). People can donate useful items to the library – like ladders, drills, carpet cleaners, camping, cooking and gardening equipment, and sewing machines – and others can borrow them for an affordable fee. This enables locals to borrow items rather than buy them for themselves and then leave them unused in a shed or cupboard for years. The aim is to build a more resourceful community, allowing people to connect with each other and share things they may need just once in a while, helping people to save money, space and resources.

Share Shed was set up in Totnes in April 2017 by the Network of Wellbeing, with the help of Totnes town council and Lottery Fund support. It was inspired by a similar initiative in the UK West country town of Frome, where the sharers had helpfully designed a kit to encourage others to set up sharing schemes.

Paul Ehrlich: ‘Collapse of civilisation is a near certainty within decades’

Fifty years after the publication of his controversial book The Population Bomb, biologist Paul Ehrlich warns overpopulation and overconsumption are driving us over the edge

The toxification of the planet with synthetic chemicals may be more dangerous to people and wildlife than climate change, says Ehrlich.

Ashattering collapse of civilisation is a “near certainty” in the next few decades due to humanity’s continuing destruction of the natural world that sustains all life on Earth, according to biologist Prof Paul Ehrlich.

In May, it will be 50 years since the eminent biologist published his most famous and controversial book, The Population Bomb. But Ehrlich remains as outspoken as ever.

The world’s optimum population is less than two billion people – 5.6 billion fewer than on the planet today, he argues, and there is an increasing toxification of the entire planet by synthetic chemicals that may be more dangerous to people and wildlife than climate change.

Ehrlich also says an unprecedented redistribution of wealth is needed to end the over-consumption of resources, but “the rich who now run the global system – that hold the annual ‘world destroyer’ meetings in Davos – are unlikely to let it happen”.

The Population Bomb, written with his wife Anne Ehrlich in 1968, predicted “hundreds of millions of people are going to starve to death” in the 1970s – a fate that was avoided by the green revolution in intensive agriculture.

Many details and timings of events were wrong, Paul Ehrlich acknowledges today, but he says the book was correct overall.

“Population growth, along with over-consumption per capita, is driving civilisation over the edge: billions of people are now hungry or micronutrient malnourished, and climate disruption is killing people.”

Ehrlich has been at Stanford University since 1959 and is also president of the Millennium Alliance for Humanity and the Biosphere, which works “to reduce the threat of a shattering collapse of civilisation”.

“It is a near certainty in the next few decades, and the risk is increasing continually as long as perpetual growth of the human enterprise remains the goal of economic and political systems,” he says. “As I’ve said many times, ‘perpetual growth is the creed of the cancer cell’.”
