Lots of truth in this. And we sure as hell need to be better stewards of that six inch layer:

This is the problem farmers on our area are experiencing this year. The flooding has washed away the topsoil in many places, or covered it with sand, or worse with heavy metals. Bad year in the heartlands.

Very interesting because ancient Egyptians relied on periodic flooding to renew their farms' soil. Of course it was a different time and circumstance. What do farmers do when their topsoil is washed away?

@RussRAB If they are lucky they can sell and move, start a new life in a city. Farmland with no topsoil is essentially parking lot.... where no one parks because it is in the middle of nowhere. Most of the farmers are mortgaged to the hilt. Not a good time.

Compost and mulch all you want, but top soil is NOT considered a renewable resource. The main component is weathered rock.

"mother nature is not a nudist--keep the soil covered and protected with vegetation or mulch."

Again (from my late partner) people are NOT more important than dirt. We seem to always forget that simple truth. Thanks for the reminder.

The bad news is that we have less topsoil every year.

The good news is that erosion is slowing down; Data from the 2003 Annual NRI, the most up-to-date NRI information available, indicate that average soil erosion rates on all cropland and CRP land have decreased more than 38 percent since 1982.

The bad news is, at this rate, crops will continue to degrade, plant diseases will rise, Chemical additives will rise. and that "six inch layer of topsoil" will eventually go to the sea, iwith the "fact that it rains".

Sorry; Scientific Agnostic here likes to look this stuff up....

Jeez.. you are one depressing fellow in the morning. 😉

@bigpawbullets Hell no! I'm feeling great. 2nd cup of coffee; birds singing in the garden...

..but I'm a 45 year retired environmental science teacher who likes to "wake and shake" those who get complacent about our environment.

I"m an optimist; I think EV's, alternative energy, and ZPG is just around the corner....

So thanks for your concern; I'm not depressed...but we need to get busy treating our soil better.

@Robecology
Ha! My comment was about your ability to depress me. 😉

wish a lot more people would get on board with the science....
and....not for nuthin'....but I'm getting a little tired of people not being able to distinguish the difference between being "negative" from being a realist. 😉

@bigpawbullets NO! There's two ways to react; get depressed or get pro-active. If you're doing what you can - from family planning, to recycling, to wise farming practices...then you're doing all you can do for the issue; you're being "pro-active"...so enjoy the birds in the garden and smile!

If you're not...then get busy....no....do NOT let this serious news depress you...it's intended only to motivate.

@Robecology
Have to agree with you Rob.

You forgot to mention the bad news is that we are not slowing down with our numbers and increasing need for dirt.

@Lavergne Far too many are willing to see negative news as "Doom and Gloom" and jump on the "Smile and Denial" bandwagen. I prefer to see it as a "Know and Grow" opportunity.

@JackPedigo I think we are "slowing down" with "our numbers"...conservation of topsoil is up. population growth rate is lowering (but will remain a "growth rate for several decades to come...but the rate itself is slowing down). So I'm optimistic we'll "fix this".

@Robecology I am not. Even if it were to stop today the momentum will mean we still keep adding more and more of us. Now, instead of 100 million net we have some 85 million net per annum. This was a big topic of discussion in ZPG and still is with population demographers.

@JackPedigo Your point isn't clear. "No I'm not"...what? Not "slowing down"? The statistics support what I'm saying; that we are, in fact, slowing down our growth rate. We're still growing; but much slower. And the slowdown should result in ZPG by the latter part of this century.

[ourworldindata.org]

It's true we are still adding to the population; 158 more births, than deaths, per minute; but this number is much lower than the rate was when it peaked in the 1960's.

True; we do increase 83-85 million per year; but that number was much higher decades ago; and we are slowing that down. Don't take my word for it; check the stats...be agnostic..

[poodwaddle.com]

@Robecology My point is we don't have until the end of the century. How many more billion people are we talking about? We can't even handle the present population and whenever the population starts to decline all the economists scream about a birth dearth. With them it's always the same story; a growing economy is paramount.

Posted by KateOahuI saw some pretty flowers on a walk today. I’d never seen a white Hibiscus before. And I do not know what the pink flowers are.

Posted by 1patriotOne of the main reasons for last year’s ‘spike’, which the media and government agencies have avoided mentioning, is the Hunga Tonga volcano eruption two years ago.
