Beautiful illustrations and story with a purpose
Get those little ones started young on understanding the impact of our actions on the world around us! This reads like a children's story should but does address a real issue. The illustrations are also beautiful.

Should Be In Every School, Home, and Library
During the 2009 International Year of Astronomy and beyond, this book should be in every school, home, and library.It is so valuable in advocating dark skies that our PHM Educational Foundation haspurchased copies for our entire school district. We highly recommend the hard copy, and we include a digitized version created by Crelin and Ziner on the Let There Be Night DVD. See www.LetThereBeNight.com.There Once Was a Sky Full of Stars is doing its part to preserve the heritage of our night sky, which many children are denied.And after you buy and read the book, pass it along to someone else to read.Don't let this book languish on a shelf.

It's okay.
This book is a little juvenile, but well written.I only hope that those who read this to their kids take the necessary effort to escort them to a dark sky place (at any cost) and show them the real sky.Otherwise, what's the point?

Join the dark sky movement and help remedy this growing problem.Most people have never even heard the term "light pollution."

A Reminder: Sky Glow is Killing Our Imaginations...
I love the whole idea of this book because it reminds people that, "Once upon a time," people did look to their night skies in awe, in wonder, in complete reverence. AND so profound was this effect, that minds were set in motion--ideas, arts, philosophies, religions, fantasies, stories, songs, adventures, inventions, hopes, dreams, faiths were born! The stars may not have been the author of human affairs; however, I would say that they were the muses, the inspiration.

This excellent book captures our modern dilemma: for all our light, we cannot see what is important and what is truly extraordinary and timeless.The illustrations of "There Once Was A Sky Full of Stars" are amazingly rendered, and they draw readers into the time before wicked sky glow begin to destroy our world, our living rhythms, and our imaginations. Crelin writes, "The Milky Way stretched overhead, once the Sun had retired to bed. Its soft cotton glow, like a river of snow, looked so close it could tickle your head." How can one not react to such sensational and yet personal imagery?

I especially like the "Points of Discussion" at the end of the story, which summaries the main lessons of the book: Viewing the Milky Way; the Problems of Sky-Glow; Environmental Considerations; Solutions.

This book is targeted at children; however, I believe it is of direct benefit to any age because of the awareness it creates. Truly, older folks have forgotten that There Once Was A Sky Full of Stars and what that simpler time meant to their development as human beings. Do we then wonder why our young people are restless or apathetic? Too much information and too much light showers down on them at such an early age... It's so sad to think of a city child locked into a concrete, man-made environment where he / she may see only one or two stars in the sky...at most, if even that!

Buy this book! Share with everyone that you know! Support changes to reduce light pollution in your own communities. Dark skies and imaginations are worth preservation.

Too Pretty...
This is a beautiful book with an important message. The illustrations are gorgeous--that being the problem! My 3.5 year old daughter thinks that the illustrations with the "pretty lights" (the ones of the cities overloaded with too many lights--"light pollution" were prettier than the ones the writer meant to be the more important ones--the lovely night skies with the stars being the important "light"). No matter...this is still a favorite story of hers and I love it too. With my coaching, she's beginning to understand the message. Just lovely! ... Read more

Description:
Five-month old hybrid poplar clones NE388 and NE359 were exposed to square-wave 30, 55, and 80 ppb O"3 (8 h/day, 7 day/week) under constant high light (HL) and light fleck (LF) during 28 May-29 June 1999, and exposed to 30 and 55 ppb O"3 under HL, LF, and constant low light (LL) during 22 May-28 June 2000 within Continuously Stirred Tank Reactors (CSTR) in a greenhouse. Ramets of these two hybrid clones received similar total photosynthetically active radiation (PAR) within the LF and LL treatments. Visible foliar symptoms, leaf gas exchange, and growth were measured. More severe O"3 induced foliar symptoms were observed on ramets within the LF and LL treatments than within the HL treatment for both clones. The LF treatment resulted in significantly greater foliar injury than the LL treatment for NE388. The LF and LL treatments generally resulted in lower photosynthetic rates (Pn) for both clones, but did not affect stomatal conductance (g"w"v); therefore, the ratios of g"w"v/Pn and the O"3 uptake/Pn were greatest in plants grown under the LF treatment, followed by those grown under LL treatment; plants grown under HL had the lowest ratios of g"w"v/Pn and O"3 uptake/Pn. Greater ratios of g"w"v/Pn and O"3 uptake/Pn were consistently associated with more severe visible foliar symptoms. The negative impacts of the LF treatment on growth were greater than those of the LL treatment. Results indicate that not only the integral, but also the pattern of photo flux density, may affect carbon gain in plants. Increased foliar injury may be expected under light fleck conditions due to the limited repair capacity as a result of continuity of O"3 uptake while photosynthesis decreases under LL conditions. ...

Description:
The responses of ramets of hybrid poplar (Populus spp.) (HP) clones NE388 and NE359, and seedlings of red maple (Acer rubrum, L.) to ambient ozone (O"3) were studied during May-September of 2000 and 2001 under natural forest conditions and differing natural sunlight exposures (sun, partial shade and full shade). Ambient O"3 concentrations at the study site reached hourly peaks of 109 and 98 ppb in 2000 and 2001, respectively. Monthly 12-h average O"3 concentrations ranged from 32.3 to 52.9 ppb. Weekly 12-h average photosynthetically active radiation (PAR) within the sun, partial shade and full shade plots ranged from 200 to 750, 50 to 180, and 25 to 75 @mmol m^-^2 s^-^1, respectively. Ambient O"3 exposure induced visible foliar symptoms on HP NE388 and NE359 in both growing seasons, with more severe injury observed on NE388 than on NE359. Slight foliar symptoms were observed on red maple seedlings during the 2001growing season. Percentage of total leaf area affected (%LAA) was positively correlated with cumulative O"3 exposures. More severe foliar injury was observed on plants grown within the full shade and partial shade plots than those observed on plants grown within the sun plot. Lower light availability within the partial shade and full shade plots significantly decreased net photosynthetic rate (Pn) and stomatal conductance (g"w"v). The reductions in Pn were greater than reductions in g"w"v, which resulted in greater O"3 uptake per unit Pn in plants grown within the partial shade and full shade plots. Greater O"3 uptake per unit Pn was consistently associated with more severe visible foliar injury in all species and/or clones regardless of differences in shade tolerance. These studies suggest that plant physiological responses to O"3 exposure are likely complicated due to multiple factors under natural forest conditions. ... Read more

Description:
The impact of a mixture of oxytetracycline, chlortetracycline, tetracycline and doxycycline on Myriophyllum sibiricum and Lemna gibba was investigated using fifteen 12,000-L microcosms (k=5, n=3). Significant concentration-response relationships were only found for M. sibiricum, where dry mass was 69, 47, 30, and 7% of controls at respective treatment concentrations of 0.080, 0.218, 0.668, and 2.289@mmol/L. Somatic endpoints were strongly and negatively correlated with percent light transmission, except plant length, which was positively correlated. Treated microcosms experienced a reduction in the percent of surface irradiance penetrating the water column as high as 99.8% at a depth of 70cm, relative to controls. Position relative to the water column was likely responsible for the differential effects observed between floating (L. gibba) and submerged (M. sibiricum) species of macrophytes. A hazard quotient assessment of the lowest EC"1"0 value indicated significant risk, exceeding the critical HQ value, but not the lowest EC"2"5 value. ... Read more

Description:
The response of tobacco plants (Nicotiana tabacum L.)-non-transformed and transformed with a metallothionein gene MThis from Silene vulgaris L.-to increase cadmium supply in the nutrient solution was compared. The transgenic plants accumulated significantly more Cd both in the roots and the leaves. Visual toxicity symptoms and disturbance in water balance were correlated with Cd tissue content. Treatment with 300@mM CdCl"2 resulted in inhibition of photosynthesis and mobilization of the ascorbate-glutathione cycle. Treatment with 500@mM CdCl"2 led to irreversible damage of photosynthesis and oxidative stress. An appearance of a new peroxidase isoform and changes in the leaf polypeptide pattern were observed at the highest Cd concentration. The level of non-protein thiols gradually increased following the Cd treatment both in transgenic and non-transformed plants. ... Read more

Description:
The relationship between ambient fine particle (PM"2"."5) concentration and children's personal exposure was investigated in Prince George, British Columbia. Repeated personal exposure measures (10 per subject) of 15 children and ambient concentrations at their neighbourhood schools were collected for a 6-week winter period in 2001. PM"2"."5 mass, sulphate (SO"4^2^-) and light absorbing carbon (ABS) were determined for all samples and the relationship between ambient concentration and personal exposure was investigated. Overall, lower particle exposures and a lower personal-ambient regression slope were found for Prince George children compared to results from other longitudinal studies of children. This suggests that in this setting indoor environments may have less influence from ambient sources and greater influence from non-ambient sources. Comparison of personal exposures and ambient concentrations for each individual indicated higher Spearman correlations for SO"4^2^- (median=0.95) and ABS (median=0.73) compared to total PM"2"."5 mass (median=0.55). A large degree of individual variability in the personal-ambient correlation was found for PM"2"."5 mass, while SO"4^2^- showed very consistent results, supporting its use as an indicator of exposure to particulate matter of ambient origin. ABS was slightly more variable than SO"4^2^- due to the influence of non-ambient or very local sources in a low number of samples. The impact of local meteorology was also investigated and inversion conditions were connected to all high ambient levels (>30@mgm^-^3). In addition, associations were found between inversion strength and personal exposure. This finding suggests that reduction of ambient concentrations during stagnant periods would result in lower personal exposure levels. This study highlights the importance of both ambient and non-ambient sources, supports the use of both SO"4^2^- and ABS as tracers of background ambient particle exposure and demonstrates the significant effect of winter meteorology on both outdoor levels and personal exposure in a valley community. ...

Description:
In situ phytoplankton microcosms were developed and characterized for use in toxicity testing. The microcosms contained 225 @mm filtered seawater maintained in 1 liter glass bottles attached to a plastic frame and immersed at 3 m under the sea surface. Synechococcus and picoeukaryote population dynamics in microcosms and the surrounding water were compared. A bloom-like behaviour observed for Synechococcus in these phytoplankton microcosms was avoided when 10% of the culture volume was replaced, every two days, by filtered seawater. After 2 weeks, no significant difference in Synechococcus and picoeukaryotes cell counts was observed in microcosms compared to the surrounding free seawater. Synechococcus fluorescence at 545 nm (phycoerythrobilin) fluctuated with a similar pattern in such microcosms and in free seawater and were shown to be correlated to light intensity fluctuations over a two week experiment. The in situ microcosms were used to study the impact of low copper additions. Synechococcus populations were dramatically decreased by copper addition, while picoeukaryote populations were increased simultaneously. Our data show that drastic changes in species composition can occur at copper concentrations encountered in polluted coastal areas. ... Read more

Description:
Tropospheric ozone (O"3) levels are predicted to stay high, being a factor within ''global change'' with potential effects on the carbon sink strength of forest trees. Hence, new approaches to O"3 risk assessment and their validation are required, although appropriate databases for adult trees are scant. Approaches based on external O"3 exposure are presently being evaluated against the ones on O"3 flux into leaves, as the cumulative uptake has the capacity for deriving O"3 risk from cause-effect relationships. The effective dose, however, needs to account for the trees' O"3 defence and tolerance in addition to O"3 uptake. The current status of promoting the preferable mechanistic O"3 flux concept is highlighted for major regions of Europe, addressing refinements and simplifications needed for routine use. At the pan-European scale, however, the flux-based concept is ready for use in O"3 risk assessment and has the potential of meso-scale application at the forest ecosystem level. ... Read more
