Cheap Flights and Climate Change – Do We Want Too Much?
What can be done about this increasingly worrying contribution to global warming?
The most important options to reduce aircraft CO2 emissions are:
Changes in aircraft and engine technology; use of alternative fuels, such as (sustainably produced) biofuels; regulatory and operational measures such as improvements in air traffic management; economic measures such as inclusion of aircraft emissions in emission trading schemes.
But, as Giovanni Bisignani, manager of International Air Transport Association (IATA), stated: “Emissions trading schemes only make sense with efficient infrastructure. The IPCC estimates that there is 12% inefficiency in air traffic management globally: we produce up to 73 million tonnes of carbon emissions each year by aircraft flying inefficiently due to air traffic management limitations”. **
On a personal level we could ask ourselves especially in the developed world: “Do we really need to fly so frequently?” The use of telework, teleconference and video conference could be largely increased to plan work and meetings. Can’t the development of land and air transportation infrastructures be balanced better according to the real needs of people and businesses? Trains could connect cities better and more cheaply for example in Europe, where the prices are not competitive with those of many flights anymore (and night train services have been reduced if not cancelled).
Life styles do matter because if millions of people want to have cheap weekends in relatively close tourist locations, many flights are needed to satisfy their desires and consequently a lot of pollution is generated. Also, our per capita emissions could be cut also by reducing the “surplus” trips, by slowing down our life rhythms and enjoying more local attractions in our free time. Who knows? We could discover the “exotic” in our own neighborhoods without flying to the Caribbean Sea…
Furthermore the relationship between the costs and the environmental externalities (i.e. costs not included in the economy like health damages caused by pollution) needs to be considered as well: there are higher marginal impacts for short-distance flights that should be considered in prices paid by passengers.
All these political, technological and personal choices are some of the good examples needed by the developing countries to follow the 21st century’s Western society along a new sustainable path which looks like the only good alternative forward.

The Canada Pine Beetle
The Canada Pine Beetle
For some time now, the extremely destructive Pine Beetle ( Dendroctonus ponderosae ) is ravaging huge areas of Canada’s forestlands and its destruction is so virulent, that it is leaving massive and easily visible scars across otherwise green foliage landscapes. In numerous areas where the pine beetle is active, various solutions for its eradication have been tried and some of these in themselves, are so toxic in nature that they would normally be classed as being a larger risk than the beetle they are attempting to destroy.
These beetles have an average life span of about one year and generally, their eggs are laid through the bark of a tree where they develop into larvae that stay under the bark all through the winter months. During the spring the larvae continue to feed under the bark and then they will change into pupae during the months of June and July. During the rest of the summer and into fall, the new adult pine beetles leave the infested tree through emergence holes they create and after drying themselves in the warm sunshine, they take off to mate and commence a new cycle by laying the next generation’s eggs under the bark of new trees.
During the time they remain under the bark of a tree, they are known to transmit a fungus type substance that stains the sapwood of the tree a blue colour. Other than discoloration, this blue colouring appears to have no adverse affects on the actual structural integrity of the tree. However, we must not forget that the damage has already been done and like a rolling snowball, it gather momentum and range of spread with each summer that comes. These beetles prefer mature trees such as lodge pole pines which are considered mature after eighty years of growth and in the Province of British Columbia, current statistics show that there are three times more mature lodge pole pines than they had over ninety years ago. Hot and dry summers make the trees more stressed and thus more susceptible to attack and infestation by this ravenous little creature. Trees which have been attacked will turn red roughly one year after the infestation and then, between one and two years later the affected trees will turn grey and all of their needles will fall off.
Another interesting fact about these little guys is they do not like it too cold! Their eggs, larvae and pupae are very susceptible to very cold temperatures and if these temperatures remain below minus 35 Celsius for a prolonged period of maybe a week, then this will kill off the eggs, larvae, pupae and generally sizeable portions of the beetle population in that area of cold weather. This being said, unless we suddenly enter the start of a new ice age all across Canada, these sporadic cold spells are unfortunately not enough to rid us of this continually spreading plague of destruction. Yes, there are action plans prepared and in place and yes, the Canadian Ministry of Forests and Range are really trying to get to grips with finding a solution to this costly problem but to date, the efforts and methodology being used has had little or no effect on the overall problem.
The good news is that an answer to this massive problem does exist and better still, it is an answer, which consists of no chemicals, no toxins, no poisons and no danger to either the forest or to the people who would apply the solution. This answer can be found right now in the form of a golden all natural organic fluid formulated around a cedar oil base. This fluid can totally eradicate the pine beetle and a few other nasty insects at the same time. It is not cheap but then again it is not as expensive as some of the other treatment that have been tried. It is non hazardous and will not harm the environment in any way and it is here and available right now. Unfortunately, for now it appears that here it must stay as the Ministry of Forests and Range are continuing their quest with what they feel they know best. Maybe someday, hopefully soon, they will realize that we can defeat this natural pest by using a totally natural substance.

Green Tip – Moms Use Clothe Diapers
Sure, this is a little messier than the easier, disposable version. However, do you even realize the amount of disposable diapers that are filling landfills?? Cloth diapers are a choice that every mother should seriously consider. Let’s look at some facts that are quite alarming…
Disposable Diapers Sobering Facts:
* from birth to about 2-1/2 the average child will go through about 7,300 diapers
* the cost for that is about $2600
* 18 billion diapers enter landfills each year
* disposable diapers make up about 3.4 million tons of trash
* health risks such as fertility issues in males, eyes, nose and throat issues and even asthma-like symptoms have been connected to disposable diapers!
* long term negative affects on animal and water life.
* the chemicals that make disposable diapers white increase the risk of cancer
* affect development
* they use more water. yep. you may need to wash cloth diapers, however, way more water is used making disposable diapers!
* a study, conducted by Anderson Laboratories in 1999 and published in the Archives of Environmental Health, found that disposable diapers release chemicals called volatile organic compounds (VOCs), including toluene, ethylbenzene, xylene and dipentene. They have been shown to have toxic health effects, such as cancer and brain damage, when used over time or high exposure.
* they use 1.3 million tons of wood pulp. that’s about 1/4 million trees every year.
* they take up to 500 years to break down.
* more viruses than you want to know about…including polio, survive for two weeks or more after disposed of.
There are many many many more reasons to avoid disposable diapers. However, I think our readers are intelligent and the above information is enough to get you thinking! Research for yourself. You will be shocked!
Go for organic natural reusable cloth diapers. You will not only be helping the environment and saving money, you will also protect your sweet precious love bugs from harm!

Sea Levels Rise
Sea Levels Rise
It is no new scientific fact that there is a slow steady increase of temperature; we’ve been studying and recording changes for a few decades. For some reason people are only now starting to take notice of how desperate the situation is.
Due to the increased temperature, sea levels are on the rise. It now is easier for boats full of scientists to access the Northwest Passage for research due to the polar icecaps melting . Areas that were once almost unreachable are now becoming navigational and the search for precious gems, gold, and oil is on! There is no end to mans greed.It makes sense that when the sea levels rise the ground surfaces slowly disappear. We will lose our agriculture farmlands. There may not be enough food needed to sustain ourselves, let alone other countries that we already support. Many farmers will lose their farms and their lifestyle.
Should sea levels on the rise be a worry about freshwater? Our drinking water is not a luxury it is a necessity and is as important for people, plants, and animals. The possible damage to freshwater due to rising sea levels should be a major worry to all of us.
For hundreds of years polar bears have been the king of the Arctic ice and roamed over vast areas of icy tundra. But with the icecaps melting away, and the distance between ice flows becoming greater, many polar bears have drowned from exhaustion before reaching shore. It also makes hunting their primary source of food, the seal, more difficult. Dying of hunger is now a probable fate for many of them.
The total extinction of many of the world’s beloved land animals may be just around the bend due to rising sea levels.

Saving Energy with Your PC
Green and Clean Computing
Little thought may be given to the energy consumption of computers, but as more and more computers are purchased each year, it is not just the number of computers that forces increased energy consumption but the way in which computers are being used that adds to the building energy burden. Research has shown that most computer desktops are not being used a great deal of the time they are running and are left on for long periods of time. As with other forms of energy consumption, electricity is wasted when it is not being used and this burns fossil fuels that emit carbon dioxide into the air and cause smog, acid rain and other detrimental environmental side effects.
The typical desktop computer consists of a system unit which houses the central processing unit (CPU), a monitor and a printer. The CPU may require 100 watts of electrical power; the monitor, which may be 15 to 17 inches, may require another 50-100 watts; a laser printer can use as much as 100 watts or more while ink printers use as little as 12 watts while printing. The cost for operating a 200 watt system all day and night, everyday, would be $125 annually, while the cost of operation for normal business hours of 40 hours per week would range around $30 annually. Considering the tremendous benefits derived from using computers, this figure may not appear extensive, but when multiplied by the many computers used on a daily basis in this country, the total grows phenomenally.
There are many ways to reduce personal computer energy consumption. Computers, printers and monitors can be turned off when not in use. Many years ago, it was considered harmful to the computer if it were turned on and off periodically during the course of a day. However, the internal circuitry of personal computers is designed to be protected from power damages that might result from on and off switching. Doing so will not substantially affect the computer’s useful life.
The use of screen savers wastes energy and should not be used. They go back to the days when, if not used, images would be ingrained on screens if they remained on too long, but updates in technology have long made the use of screen savers unnecessary.
The United States Environmental Protection Agency has also developed technology for computers and monitors that can be programmed to automatically power down to a lower power state when not in use. This “sleep mode” can reduce energy consumption by 60% to 70% and these “Energy Star” computers serve to gain efficiency without any loss in computing performance.
Green computing extends beyond the personal computer to the use of related devices and materials. For example, paper waste can be reduced by printing as little as possible and only when necessary, recycling waster paper, using electronic mail instead of faxing to eliminate the need to produce a hard copy, and trying to print on both sides of the page when possible. In addition, printer and toner cartridges can be recycled. Although this is a practice that has been discouraged in the past by printer and toner cartridge manufacturers, such recycled cartridges save resources and reduce pollution and solid waste. Disposing of electronics as well can be done through recycling agencies to reduce waste and provide for recycling of functional equipment.
Finally, green computing also means not buying new equipment unless there is a real need for it. Close investigations can be made regarding upgrading hardware or software before purchasing a new computer. However, if the determination is made that a new computer system should be purchased, there are “Energy Star” computers, monitors and printers on the market. In addition, ink jet printers use 80% to 90% less energy than laser printers and soon, even “Green Computers” will reach the marketplace for sale.
