Mankind has been changing the world for quite some time. Some would say that when Homo erectus tamed fire 1.8 million years ago … humans began dominating the planet. [1]  Others talk of the introduction of farming or the Industrial Revolution. More recently, humans have been described as a geophysical force on a par with the earth-shattering asteroids and planet-cloaking volcanoes. [2]

I’ve done quite a bit of surfing and reading about the results of mankind’s manipulation. It occurred to me that not everyone has the time to spend researching but everyone needs to know about what’s happening to our planet, our home.

I’ve amalgamated various articles on a particular topic into a readable summary. Read one page and you’ll get an idea of the thoughts out there, about that issue.

Please talk to your friends about what you’ve read. The more people in ‘the know’, the better. We can’t solve the problems if we don’t all know about them!

Soil degradation- water & wind

Soil is the earth’s fragile skin that anchors all life on Earth

Soil is the earth’s fragile skin that anchors all life on Earth. It is comprised of countless species that create a dynamic and complex ecosystem and is among the most precious resources to humans. [1]

Human activities that significantly reduce soil cover (e.g., tillage and clear-cutting) and/or intensify wind or water movement (e.g., the removal of windbreaks and channelization of streams) often result in accelerated erosion that exceeds geologic erosion rates by several orders of magnitude.

GROUND Water scarcity

This is a LONG post. It’s an BIG issue.

Nearly 20 years after the World Bank began warning of a looming water crisis, the combination of a surging population, a growing global middle class and a changiwater scarcityng climate is straining water supplies

“Humankind is running out of water at an alarming pace,” Peter Brabeck, chairman of Nestlé, says. “We’re going to run out of water long before we run out of oil.” Continue reading

Peak oil theory considered

This post begins with history. At *** it start discussion of the likely oil peak in the future.

The peak oil theory holds that any individual oil field (or oil-producing country) will experience a high rate of production growth during initial development, when drills are first inserted into a oil-bearing reservoir.  Later, growth will slow, as the most readily accessible resources have been drained and a greater reliance has to be placed on less productive deposits.  At this point — usually when about half the resources in the reservoir (or country) have been extracted — daily output reaches a maximum, or “peak,” level and then begins to subside.  Of course, the field or fields will continue to produce even after peaking, but ever more effort and expense will be required to extract what remains.  Eventually, the cost of production will exceed the proceeds from sales, and extraction will be terminated.

Clean energy vs. oil

ALTERNATIVE ENERGY

 When oil prices fall, low-carbon sources of energy such as wind and solar power may seem less attractive to investors, creating doubts about the pace of the world’s transition to clean energy.

Some renewable energy projects which aren’t completely bedded down are certainly … delayed but at the same time, (the low oil price takes) off the market very expensive oil projects. Tar sands and exploration in the Arctic have become less attractive due to the oil price crash. [1] Continue reading

Plastic Pollution

ocean plastic

Plastic Pollution has become a man-made global catastrophe

The proliferation of plastic products  has resulted in an increase in production from around 50 million tonnes in 1950 to 245 million tonnes in 2008 (Plastics Europe) [1]

To get that into terms you can understand, every two years we make enough plastic to be the equivalent of the weight of the 7 billion people on earth. [2] About half of this will be used just once then thrown away.

Annually, approximately 500 billion plastic bags are used worldwide. More than one million bags are used every minute. A plastic bag has an average “working life” of 15 minutes. Continue reading
