The Ratatouille effect

Tuesday, March 10th, 2009

I have heard references at various times to the so-called “Bambi Effect”, the supposed effect of the classic Disney animated film, where Bambi’s mother is killed by hunters, as a contributing factor to the decline in hunter numbers across North America in recent decades.

There is no denying that deer are attractive animimals, and people understandably don’t enjoy the thought of them being killed, even if it is for food.

So I’ve been waiting to see if folks are going to start cuddling up to rodents, considering the popular success of the wonderful Pixar animated feature Ratatouille.

Some radical environmentalists are on record as stating that the earth’s population should be reduced by several billion people, perhaps by re-introducing diseases such as the bubonic plague.  Even Prince Philip is quoted as stating, “In the event that I am reincarnated, I would like to return as a deadly virus, in order to contribute something to solve overpopulation.“  If they play their cards right, they might be able to use the Ratatouille Effect to ban rodenticides, and they would be well on their way to their goal.

Personally, although I thoroughly enjoyed watching Ratatouille, I still detest rats, and will kill them at any opportunity.

But then, I also hunt deer.

The Great Tar Sands Debate
Tuesday, March 17,
7:00pm

Andrew Nikiforuk, author of Tar Sands: Dirty Oil and the Future of a Continent, and Dr. Carolyn Preston, Executive Director of the Petroleum Technology Research Centre, will present both sides of the Tar Sands development debate. This is your opportunity to learn the facts and form your own opinion.

Andrew Nikiforuk’s book will be for sale. Refreshments will be served and everyone is welcome.

The Great Tar Sands Debate is cosponsored with the Council of Canadians—Prince Albert Chapter.

With the interest generated by a recent article about Canada’s oil sands in National Geographic magazine, this debate should attract a good crowd.  Barring something really important preventing me, I know where I plan to be on the evening of Saint Patrick’s Day.

Toilet paper guilt

Saturday, March 7th, 2009

When I was a kid back on our bush farm I knew what it was like to wipe my backside with pages from the Eatons catalogue, and compared to that experience I think most toilet paper is  pretty luxurious.  In other words I don’t require quilted TP that’s been soaked in skin lotion.  Recycled content is fine, and I don’t mind if it hasn’t been bleached to a brilliant white.

However when I read about the latest Greenpeace campaign against soft toilet paper I thought it went overboard in demonizing the Canadian forest industry.

I think that this response by Patrick Moore (former Greenpeace director) provides a good rebuttal.  A couple of  excerpts:

…Paper is made from the sawdust and chips left over from sawmilling, and from logs that are not suitable for making lumber. In environmental terms this is the beneficial use of what would otherwise be a waste product. Indeed, the parts of the log that are not suitable for paper, such as the bark and fine sawdust, are burned to make energy to run the sawmill and to dry the lumber.

In the end, 100 per cent of the tree is used. What is wrong with that?

Greenpeace and the NRDC claim that cutting trees to make paper is causing deforestation and huge emissions of greenhouse gas. This is simply false. Nearly all deforestation is caused by clearing forests for agriculture or for human settlement. Forestry causes reforestation, the opposite of deforestation. To verify this all one need do is read State of the World’s Forests by the Food and Agriculture Organization of the UN.

The International Panel on Climate Change and the Kyoto Climate Treaty specifically recognize that forest management plays a positive role in absorbing CO2 and preventing its release in the first place. It is stunning that Allen Hershkowitz, senior scientist for the NRDC, seems to be unaware of this.

Three wolves

Wednesday, February 18th, 2009

Logan and Arnie have managed to harvest three wolves so far this winter.  The first two are black, and the most recent one is grey.

The wolf population in Saskatchewan’s agriculture/forest fringe area has been increasing dramatically in recent years, to the point where predation on livestock is a problem in some areas.

Some people are opposed to trapping.  However I see it as a valid way to supplement an income, provided it is done in compliance with provincial legislation.  In fact the trappers that I know tend to have a good understanding of conservation biology, and see themselves as responsible stewards of our province’s renewable resources.

May they have continued success, and here’s hoping that fur prices increase.

Wolf Willow

Monday, January 26th, 2009

I’ve never been to Eastend, Saskatchewan.  In my mind it’s mostly been associated with Scotty the T-Rex.

However I have been to Cypress Hills Interprovincial Park, straddling the Saskatchewan/Alberta border a bit to the west of Eastend.  It is a fascinating area, with its lodgepole pine forests stuck in the middle of the prairies.

My perception of Eastend, Cypress Hills and southern Saskatchewan in general has been changed by the book Wolf Willow, by the American author Wallace Stegner.  It’s been on my to-read list for some time, and I finally got around to reading it during my days off around Christmas.

Wolf Willow works for me on a lot of levels.  It is a strange blend of non-fiction and short stories.  Stegner reminisces about his childhood in the village of Whitemud (Eastend) and a homestead on the Saskatchewan-Montana border, makes the history of the area breathe, and describes the natural environment in a way that makes it come alive – the shrub wolf willow (Eleagnus commutata, also known as silverberry) does indeed have a distinctive aroma.

I highly recommend this book for anyone interested in ecology, history, frontier attitudes, homesteading, law enforcement (North-West Mounted Police), Blackfoot/Sioux/Cree and other native peoples, Métis, Canadian vs. American attitudes, or just a good read.

Green stimulus

Thursday, January 22nd, 2009

The new federal budget will be presented in just a few days.

That’s the Canadian federal budget, in case you’ve been totally immersed in Obama news.

There’s a lot of pressure on the Conservatives for big spending projects to stimulate the flagging economy.  As much as I hate to see Canada getting into deficit spending again, building up the debt for our children to pay off, I do understand that in times of recession a case can be made for the government running deficits while spending more to stimulate the economy.  I just hope that the feds will choose their spending priorities wisely.

If spending is to increase, I agree with the four former Prime-Ministers who have issued a call for a Green Stimulus package as part of the budget.  I don’t know if all of the elements are sound, but I like the idea of increased spending on alternative energy sources, including biomass from the forest.

I also would like to see a more generous grant for home energy retrofits.  The current ecoENERGY Retrofit program provides some incentive but it could certainly be improved.

And maybe the feds could match or increase the new $50 Low/Dual-Flush Toilet rebate water conservation program announced by the Saskatchewan provincial government last week.  I’d follow my cousin Roger’s lead and save on my water bill by peeing behind the shed but the neighbours would probably complain.

Toilet talk

Tuesday, January 20th, 2009

If it’s yellow

Let it mellow

If it’s brown

Flush it down

I must admit that I don’t make a practise of following that old water conservation slogan.  If I tried it, someone in my house would have a talk with me.

However I do feel somewhat guilty about using 13 litres of municipally-treated water each time I tinkle (which happens more frequently since I turned 50 than it used to).  Water conservation is an important part of natural resource stewardship.  Not to speak of saving money.

So when I found out that the Saskatchewan Watershed Authority is willing to pay me $50 per toilet to replace my old porcelain thrones with new low-flush (6-litre) or dual-flush (6-litre and 3-litre) models, I decided to look into what dual-flush models are available.  Since I was in Saskatoon on Saturday anyway, it was a good excuse to browse through Home Depot.

Unfortunately I was still thinking in mid 1990s prices, from the last time we replaced a toilet.  I’m sure we paid less than $100 for a basic model at that time. On Saturday the only dual-flush toilet that Home Depot had in stock was selling for just under $300 before taxes.  The $50 rebate would help, but I’m still having trouble with the cost of replacing the three toilets in our house.

Apparently there are technical factors to consider when buying a low-flush toilet – such as whether the trap is glazed, or only the bowl itself is glazed.  It makes sense that the brown stuff would clog less in a nice slippery glazed trap than in a rough-surfaced trap, but I admit I had never pondered that fact.  The news story at the link above says a good model would cost in the $400-$600 range.

I guess the $300 toilet at Home Depot must have an unglazed trap.

However it seems to me that it would take a lot of low-flushes to justify the extra cost of a more poop-friendly model.

Lots to think about.  The research will continue.  Meanwhile any practical toilet advice would be appreciated.

(Please excuse my potty-mouth language in this post – I’ll try to get my mind out of the sewer before my next post)

Mack Williams – woodlot role model

Wednesday, January 7th, 2009

For the one or two of my readers who might have an interest in private woodlot management, I refer you to the Mack Williams Woodlot Story.

It’s inspiring to read about how Mack transformed a degraded Ontario farm into a thriving mixed forest.   As he states,

… As I age I relax on the property much more than ever before, with a folding chair at various points on the trails. I may read, or just enjoy what Mother Nature has been doing. It is exciting to see, within my adult lifetime, a transition from an open, windswept eroding sandy landscape, to plantations up to 59 years old, some with dense sugar maple understory. I have seen quality logs from trees planted by myself and by family members. I see it becoming a sheltered place of peace and refuge from a hectic world. I am aware of gradual changes happening in the soil. I marvel at the contribution I am sure it is making to quality of air and ground water. I dream that it may become a place for teaching health, biological and artistic subjects. I can see the potential growth that lies ahead, including both the maple syrup and timber potential of the hardwood parcels. I can also see much work I could have done, had I had more time and energy, to make the stands even better. I can see other courses of action I could have taken, with equally exciting results. 
I marvel that Canada is a nation of trees and forests, an ecological, economic, social and spiritual treasure. I wish more Canadians could share this awareness and appreciation. I wish more landowners could have similar dreams and the energy and skills to make them happen. I wish that society might recognize how much it benefits from such a forest, perhaps much more than the individual owners, and how it might benefit greatly from offering realistic support to those engaged in private land forestry …  (ref)

Inspiring stuff for a someone who is just a year into being a private woodlot owner (part-owner).  Mack is a role model worth emulating.

However it’s discouraging to consider that he bought the land in 1946 when he was 22 years old.  I recently had my 52nd birthday, so when I reach Mack’s age (84, 85?), any trees that I plant this year will still be juveniles.  However his story ends with this encouragement …

… And I would hope that landowners everywhere will understand that it is never too early or too late to start.  (ref)

I suppose that if I plant fast-growing hybrid poplar I could still be around to reap the benefits.  However I’m more likely to choose slower-growing native species, and hope that my children and grandchildren will appreciate the results.

Good scum

Tuesday, December 9th, 2008

With increased concern about the apparent link between elevated atmospheric CO2 levels and climate change, there has been a real push recently to produce liquid fuels from organic matter. However enthusiasm over grain-based ethanol is tempered by concerns about increased cost of food, especially for poor countries where a significant increase in the price of grain could make a difference between having a meal each day or going without.

As a forester, I would like to see more research into the production of cellulosic ethanol, especially if it can be produced economically from parts of the tree that presently get piled and burned.

However a really fascinating option is the idea of producing fuels from algae. Those disgusting scummy green ponds may have a lot more value in the future.

Here’s a video clip about one private research facility that’s investigating algae biodiesel.

Carbon bomb?

Saturday, October 18th, 2008

As reported in various news media earlier this year, Greenpeace recently put out a report calling Canada’s boreal forests a “carbon bomb”. Interestingly, this article seems to assume that the instant a tree is harvested, all its carbon is instantly vaporized into the atmosphere.  There is no mention of the long-term carbon sequestration in wood frame houses and other wood products.  There is also no serious analysis of the natural role of fire in the boreal forest.

For some balance, click here for a science-based article on boreal forests and the carbon balance.
