Habitat loss threatens all our futures, world leaders warned

GR: I suppose that we all know what’s causing habitat loss. The human population has grown without limits and like bacteria in a petri dish, we are using up the Earth’s resources. The outcome was predicted long ago. Couple those predictions with the unexpected rapid intensification of climate change and you can see why our ultra rich citizens are hoping to find water on Mars and other planets. They hope to soon be saying, “So long and thanks for all the fish.” Of course, the rest of us can’t wait for the day that they all fly away in an Elon Musk version of the Golgafrinchan Ark Fleet Ship B.

“As a UN conference convenes to work out a new deal for protecting the planet’s biodiversity, the focus falls on the nations that are not attending.

“Amid the worst loss of life on Earth since the demise of the dinosaurs, the agenda at the Convention on Biological Diversity (CBD) in the Egyptian resort of Sharm el-Sheikh could hardly be more important, but the spirit of international collaboration appears to be as much at risk of extinction as the world’s endangered wildlife. The United States has never signed up and Brazil is among a growing group of countries where new nationalist leaders are shifting away from global cooperation.

“The two-week meeting of the CBD is its first in two years. It has always been the neglected sibling of its twin, the United Nations Framework Convention on Climate Change. The two organisations were conceived amid great hope at the Rio Earth summit in 1992 but while the energy transition has attracted heads of state interested in billion-dollar renewable projects, the effort to save the natural world has been left to weak environment ministries, conservation NGOs and underfunded scientists” –Jonathan Watts. Habitat loss threatens all our futures, world leaders warned | World news | The Guardian

World Scientists Warning to Humanity

Scientists Warn of Global Dangers

Tomorrow is World Population Day. A good day to take note of the warnings coming from the world’s scientists.
“Humanity is on a collision course with Nature.
A damaged Nature will survive. We may not.
We must change course to avert an ecological disaster.”
Twenty-five years ago, 1700 scientists published a warning and recommendations for controlling environmental pollution and population growth. Except for global efforts to curtail ozone emissions, the warning had no effect. Last fall, more than 20,000 scientists issued a new warning urging efforts to change our disastrous path toward global ecosystem devastation.

Switch to Renewable Energy

GR–Ode to concerned scientists: They see the danger, they blow the horns and clang the bells, and they wait. But the ramparts remain empty. They turn to their family and friends, but dreamlike their voices are too soft and none respond.

“Fifteen thousand scientists have issued a dire warning to humanity about impending collapse but virtually no-one takes notice. Ultimately, our global systems, which are designed for perpetual growth, need to be fundamentally restructured to avoid the worst-case outcome.

“For a moment, the most important news in the entire world flashed across the media like a shooting star in the night sky. Then it was gone. In November, over fifteen thousand scientists from 184 countries issued a dire warning to humanity. Because of our overconsumption of the world’s resources, they declared, we are facing “widespread misery and catastrophic biodiversity loss.” They warned that time is running out: “Soon it will be too late to shift course away from our failing trajectory.”

“This is not the first such notice. Twenty-five years ago, in 1992, 1,700 scientists (including the majority of living Nobel laureates) sent a similarly worded warning to governmental leaders around the world. In ringing tones, they called for a recognition of the earth’s fragility and a new ethic arising from the realization that “we all have but one lifeboat.”

“This second warning contains a series of charts showing how utterly the world’s leaders ignored what they were told twenty-five years earlier. Whether it’s CO2 emissions, temperature change, ocean dead zones, freshwater resources, vertebrate species, or total forest cover, the grim charts virtually all point in the same dismal direction, indicating continued momentum toward doomsday. The chart for marine catch shows something even scarier: in 1996, the catch peaked at 130 million tonnes and in spite of massively increased industrial fishing, it’s been declining ever since—a harbinger of the kind of overshoot that unsustainable exploitation threatens across the board.” –Jeremy Lent (What Will It Really Take to Avoid Collapse?).

How Many of You Switched to Renewable Energy?

In recent posts, I described the warnings of impending disaster. I didn’t expect to have an impact, and I wasn’t wrong. As Jeremy Lint points out in the article above, the media avoidance of unappetizing topics is too complete. And of course, our leaders in power avoid the subject in their subservience to wealth. My first hint that good advice for avoiding collapse would be futile was the minimal response to my discovery of the simple and inexpensive means for everyone to switch their homes from fossil fuel energy to renewable energy. Like Pangloss, I’ve remained hopeful. But I read that book, and now I’ve turned to a more practical concern; the post-anthropocene survivors, the weeds, have absorbed my attention. Today’s weed is Shepherdspurse, a foreign but familiar little mustard that feeds butterflies and yields medicines for us humans.

How Marine Algae Could Help Feed the World

GR: If we stay on our present path bringing 200,000 more mouths to feed into the world every morning, bugs and algae will be well on their way to replacing hamburger by 2050. The article below and many like it, consider feeding our growing population a challenge, not a catastrophe. Need to change.

“Our planet faces a growing food crisis. According to the United Nations, more than 800 million people are regularly undernourished. By 2050, an additional 2 to 3 billion new guests will join the planetary dinner table.

“Meeting this challenge involves not only providing sufficient calories for every person, but also assuring a balanced diet that includes the protein and nutrients that are essential to good health. In a newly published study, we explain how marine microalgae could be a sustainable solution for solving global macro-hunger.

Problems with Current Food Production Systems

“The current Western diet requires vast amounts of land, water and energy, is heavily polluting and is a major contributor to climate change. Providing nutritious food for an ever-growing global population with increasing per capita demand is pushing our current food production system beyond its limits.

“Livestock production is replacing forests with cropland and pastures for meat and animal feed. Nitrogen and phosphorous fertilizer used to grow feed grain and other crops is degrading soils and creating biological dead zones in some 400 estuaries around the world.” –William Moomaw and Asaf Tzachor (How Marine Algae Could Help Feed the World).
