Drug-resistant infections – the new pandemic? And, a tangled network of tiny tubes, pulsating beneath our feet. Fungal networks below ground sustain life above.

I met Vivien Sansour for the first time back in 2016, in her home town of Beit Jala, on the southern edge of Bethlehem, in Israeli-occupied Palestine. An anthropologist by training, Vivien has turned to the promotion of food and the cultural sovereignty tied to growing one’s own and saving the seeds, as her life’s work.
Earth’s oceans are warming at a remarkable rate. Over ninety percent of the atmospheric heat humans have generated in the course of the past decades has been absorbed by Earth’s oceans. The consequences for oceans and atmosphere have been dire, and promise to play out over centuries, regardless of what we do.
The cedar is Lebanon’s national symbol. But Lebanon’s renowned cedar forests are not what they used to be. Today, all that remains of Lebanon’s cedar forests are a dozen fragmented islands, threatened by livestock grazing and climate change. The key to restoring them is their genetic diversity.
Planet Earth is covered in water. Ninety-seven percent is in earth’s oceans. Most of the rest is frozen solid — locked up in sea ice and terrestrial ice sheets, glaciers and permafrost. Earth’s cryosphere plays a huge role in regulating climate. As our planet warms, its cryosphere is slowly melting, triggering positive feedbacks that make earth scientists worry.
Climate change is a human rights issue. Nowhere is this clearer than in Israeli-occupied/colonized Palestine, where land and natural resources required for climate adaptation are controlled by Israel, and systematically denied to Palestinians. Of all these resources, none are more vital than water.
Long before the ‘intractable conflict’ between Israeli Jews and Palestinians gets resolved, climate change will have thrown everything up for grabs — literally. It already has.
It’s the ultimate green dream: some device or substance that can capture the sun’s infinite flood of energy, store that energy, release it as heat and electricity — in controlled fashion — then absorb it all over again in a continuous closed loop. A little organic molecule called norbornadiene promises to make dreams come true, in the crucial realm of home heating and cooling.
Earth’ surface is one degree warmer today, on average, than it was at the start of the industrial revolution 200 years ago. One degree doesn’t seem like much. The Paris Agreement would limit global temperature rise to two degrees. Sound like a conservative precautionary measure? Perhaps it isn’t.
Bacteria and fungi, Earth’s quintessential biochemists, are famous for the odd molecules they produce. But human beings are no slouches. According to one estimate, global commerce swells with thousands of industrial chemicals, many completely novel, some very toxic
Thirty-five years after gaining independence, Belize, Central America’s youngest nation, stands on a cusp of development that will either protect crucial wildlife habitat or gradually lose it to wide-scale agriculture.
For those who thought that corporate concentration in the food industry couldn’t get tighter, wake up and smell the coffee. The Big Six seed and farm chemical producers are now on the verge of coalescing into three. Amazon may soon be the world’s biggest supermarket.
Standing on the edge of little Battir, I feasted my eyes on an astonishing sight: an amphitheater of ancient stone terraces covered in a cornucopia of fruits, vegetables, herbs and trees — including olive trees over a thousand years old.
Imagine an electric-powered fleet of Canada Post vehicles, along with vehicle charging stations at post offices. And postal banking, where loans could be secured for renewable energy installations and home energy retro-fits. Listen up.
Last fall I rode 1500 miles from Taos, New Mexico to New Orleans on a 1983 Yamaha xs-650. It was my first solo, long distance bike trip and New Orleans — a legendary city — seemed like a good destination.
A mild mid-March in Canada’s notoriously frigid prairie capital cannot be definitively pinned on global climate change. Still, for anyone willing to listen, read and watch, the writing is on the wall. Earth is warming — and fast.
Will global capitalism eventually wean itself off fossil fuels? Can wind, solar, geothermal and other renewable energy sources generate enough joules to drive permanent economic growth? Should carbon emissions be taxed?
Things constantly change. Everyone knows it. Steady, sometimes sudden change provides contour to individual human lives. Now, it seems humans have changed planet Earth like it’s never been changed before.
Like Earth’s climate, Manitoba Hydro’s office tower — in the city of Winnipeg — is an integrated system. As Earth’s climate warms, energy efficient buildings like this will be in demand.
