We Can All Do
We Can All Do
Saving the rainforests and environment is not an easy task. It took many years of neglect, mainly on our part, in keeping the environment clean. We polluted our air and our water through chemicals and different types of bacteria and debris. We used paper products that were not recyclable and or were not biodegradable.
Rome wasn’t built in a day as the old cliche states, but we managed to ruin our planet over the years and unfortunately it will take longer than a day to rid the Earth of all the garbage we have dumped on it. It is so easy to throw a piece of paper out of your car window, instead of finding a receptacle to dispose of it, or to throw empty cans in with your regular garbage instead of separating them for the recycle pickup or to bring bottles back to the store. Let’s not forget the broken down refrigerators, t.v.s, mattresses, etc on the side of the road.
I have traveled to third world countries and it breaks my heart to see that. They have no means of garbage disposal and they certainly don’t know how to recycle. Most of the people, although poor, take pride and keep their properties neat and debris free, others do not care. The same goes for people who live here on Earth. Some are proud of what they own and others could care less.
By the inch it’s a cinch, by the yard it’s hard. If we all do our part in what ever little way, we can help improve Mother Earth and make it liveable for generations to come. Let’s start by picking up our litter, don’t let the water run when brushing your teeth, use rags instead of paper towels, carpool if you can, don’t discard items on the side of the road to make it look unsightly, but for the most part…. Be Proud Of Where You Live and What You Have!!!!!!

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.

Conservation Efforts
Conservation Efforts
How often have we come across lovely historical sites suffering from neglect and misuse? Every country needs to take good care of its historic places. Because things like malls, stadiums and highways can be built again. But a historic place which is neglected and misused will lose its glory and slowly disintegrate into zilch. And no amount of action plan or noble intentions can ever bring a historic place back to its former glory when it has been totally neglected and abused by us. The oldest of historic sites can be preserved for the future generations if we have a proper plan for their conservation.
Conversation of historic places requires a systematic approach. If the historic site is conserved with the help of a proper plan, it will show amazing results. While chalking out a plan for the conservation of historic sites, it’s very important to keep the costs under control. If the costs go up to an unwanted level, it will draw criticism from the general public and act like a death sentence for the conservation of other similar projects in the future.
The first thing which should be done by the restoration experts is to check the age of the historic site. This can be easily achieved by conducting a series of scientific tests. It can also be done if there are public or archaeological records of the site. Once we know the actual age of the historic site, we get to know the actual worth of the site – this doesn’t mean that if a site is not very ancient – it’s not worth taking care of.
Also check the sturdiness of the materials which have been used on the historic site. This will need a proper list of all the materials used on all the structures found on the site. Factors such as the effect of temperature, humidity, weathering, fire, air pollution, storms and flood on the material found on the site needs to be studied in detail, so that best possible plan to prevent further degradation of the site can be prepared.
Don’t forget to note the architectural design of any structures present on the site. This is needed to take help of conservation experts according to the style they specialize in. Taking the help of the best of experts who are not competent in the architectural design displayed at the historic site would create a major problem for your conservation project.
Your team of conservation experts also need to keep a track of all the past repairs and changes made on the historic site. The problems faced by the previous restoration team while restoring or repairing the historic site too needs to be researched and noted down. Always remember materials like wood and leather rot quite easily, on the other hand stone articles and pottery items always manage to survive better. Once you have finished your complete study of the historic site, you can then do the restoration part of the site step by step in a phased manner till it is complete. You might even have to restrict the number of visitors, once it has been restored, as although the site has got its former glory, it might not be in a state that it can be exposed to an endless number of people everyday.

Gasification Sees a New Dawn and How it Will Benefit Us All
Gasification Sees a New Dawn and How it Will Benefit Us All
If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.
So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?
What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.
This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.
Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.
Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.
These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.
Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.
Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.
Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.
Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.
Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.
