David Suzuki: Stop Buying So Much Stuff
How much stuff will you give and receive this holiday season? Add it to the growing pile—the 30-trillion-ton pile. That's how much technology and goods humans have produced, according to a study by an international team led by England's University of Leicester. It adds up to more than all living matter on the planet, estimated at around four trillion tons.
Scientists have dubbed these times the "Anthropocene," because humans are now the dominant factor influencing Earth's natural systems, from climate to the carbon and hydrologic cycles. Now they're labeling our accumulated goods and technologies—including houses, factories, cars, roads, smartphones, computers and landfills—the "technosphere" because it's as large and significant as the biosphere, atmosphere and hydrosphere. Researchers estimate it represents 50 kilograms for every square meter of Earth's surface and is 100,000 times greater than the human biomass it supports.
As CBC science commentator Bob McDonald wrote, "Our technology is a super-organism that competes with the biosphere for resources and is winning that competition by taking over the surface of the planet."
Report co-author Mark Williams explained the significance: "The technosphere can be said to have budded off the biosphere and arguably is now at least partly parasitic on it. At its current scale the technosphere is a major new phenomenon of this planet—and one that is evolving extraordinarily rapidly. Compared with the biosphere, though, it is remarkably poor at recycling its own materials, as our burgeoning landfill sites show. This might be a barrier to its further success—or halt it altogether."
Living systems renew and recycle. Organisms die, get eaten or absorbed by other organisms, and other life takes their place. But much of what we produce takes enormous amounts of natural, mostly finite resources to make and breaks down slowly, if at all. It covers the land and fills oceans, and even extends into space. As the human population continues to grow and consumerism shows no signs of abating, the technosphere expands, causing pollution, contamination and resource depletion, further upsetting the delicate natural balance that keeps our planet habitable for humans and other life forms.
Many things we've invented have made our lives easier in some ways. But much is unnecessary and, we've learned, a lot comes with consequences we didn't foresee—such as climate-altering greenhouse gas emissions from our obsession with private automobiles and cheap energy.
If this pace continues, we'll leave a fascinating fossil record for any intelligent species that comes across our planet in the future. But that may be all. If we want to survive as a species, we must get a handle on population growth and consumerism. It's something to consider this time of year, when so much time and energy are spent on acquiring new stuff, for ourselves and others.
Although population growth is starting to stabilize, curtailing growth requires greater access to effective, voluntary family planning and birth control, increased women's rights including the right to make decisions about their bodies and reproduction, and reducing poverty.
We can all do our part to reduce consumption. We might find we're happier when we do. At the end of his life, my father didn't talk about accomplishments or possessions or wealth. He talked about connections to friends and family and shared experiences. Although he didn't have a lot of material possessions, he felt wealthy and happy.
That's what life is about. A new car or smartphone won't make you happier in the long run. Nor will it fill gaps caused by loneliness or lack of connection to others. That doesn't mean we should live without material goods, but we should consider what we really need, and make sure we recycle items we can no longer use. Reduce, re-use and recycle! And reconsider what really makes us happy.
More important, during the holiday season, we should nurture our connections to friends and family, and give gifts that won't add to the technosphere. We can share time, experiences and food. Those who find themselves alone might consider volunteering to help others during what can be a difficult time.
May you all have a joyous season, focused on the important things in life. And may the New Year bring humanity a greater understanding of what truly makes life worthwhile.

Two years ago—long before coal became one of the most dominant and controversial symbols of the 2016 presidential election—Bloomberg Philanthropies approached production company RadicalMedia with the idea of creating a documentary exploring the U.S. coal mining industry. Last spring, they brought on Emmy-nominated director Michael Bonfiglio, tasked with forging a compelling story out of the multitudes of facts, statistics and narratives underlying the declining industry.
The Sierra Club released a new analysis Friday that found that transitioning all 1,400+ U.S. Conference of Mayors member-cities to 100 percent clean and renewable electricity will significantly reduce electric sector carbon pollution nationwide and help the U.S. towards meeting the goals of the Paris climate agreement.
As Trevor Noah noted during The Daily Show episode last night (starts at 2:25), the real reason Trump has these rallies is to "get back in front of his loyal crowds and feed of their energy." Noah believes that "Trump supporters are so on board with their dude he can say anything and they'll come along for the ride."
Watch above as Newsy explains that the decision comes despite serious concerns from the environmental and scientific community, and Tribal Nations about a declining, isolated grizzly bear population with diminishing food resources and record-high mortalities.

Seismic airguns exploding in the ocean in search for oil and gas have devastating impacts on zooplankton, which are critical food sources for marine mammals, according to a new study in Nature. The blasting decimates one of the ocean's most vital groups of organisms over huge areas and may disrupt entire ecosystems.
And this devastating news comes on the heels of the National Marine Fisheries Service's proposal to authorize more than 90,000 miles of active seismic blasting. Based on the results of this study, the affected area would be approximately 135,000 square miles.

Is coconut oil:
- good for you
- bad for you
- neither good nor bad
- scientists don't know
The subject of this question is the source of a disagreement. Initially, the question was thought to be settled decades ago, when scientist Ancel Keys declared all saturated fats unhealthy. Coconut oil, which is solid at room temperature, is a saturated fat.
The U.S. Fish and Wildlife Service removed grizzly bears in the Greater Yellowstone region on Thursday from the Endangered Species List. The decision comes despite serious concerns in the scientific community about a declining, isolated population with diminishing food resources and record-high mortalities, as well as strong opposition from an unprecedented number of Tribal Nations.

ArborGen Corporation, a multinational conglomerate and leading supplier of seedlings for commercial forestry applications, has submitted an approval request to the U.S. Department of Agriculture, Animal and Plant Health Inspection Service to deregulate and widely distribute a eucalyptus tree genetically engineered (GE) to be freeze tolerant. This modification will allow this GE variety to be grown in the U.S. Southeast. The reason this non-native and highly invasive tree has been artificially created to grow outside of its tropical environment is to greatly expand production capacity for the highly controversial woody biomass industry.
