Can Nuclear Energy Save You From Global Warming?

Just imagine a world with abundant energy, enabling you to live the good life forever... Isn't that what most of us crave? Nuclear energy is magic isn't it?

Nuclear energy has no greenhouse gas emissions. The latest technology has made it safe and we can bury nuclear waste without worrying about radiation. Business as usual without doing any harm.

Perfect!

Well, is it?

Nuclear energy is magical thing. It's hard to understand how it works and it's easy to get bamboozled by claims made by the nuclear magicians – scientists – as well as by opponents.

Take veteran environmentalist Dr James Lovelock, of GAIA fame who says only nuclear energy can save us from global warming. Or Dr Helen Caldicott who says it's too dangerous and we do not need it.

And governments ... Well, depends on who you talk to.

Your life is full already without figuring out what is valid and what's not. Right?

Easier to just leave it to "Them."

But stop!

Find out the facts on nuclear energy and nuclear radiation hazards. Then make up your mind – and next time there is an election you vote with some knowledge under your belt. There is plenty of information out there to help you make up your mind and I'll give you a leg-up.

So, here is an easy framework. Imagine experiencing a certain "knowing"about this important issue on your way to the ballot box, or in talking with your friends.

Given that global warming is a real threat, and global energy demand is ballooning, then the nuclear energy debate is essentially about four Big Issues.

1) Can nuclear energy deliver on a low-emission or even non-emission basis?


2) Is nuclear energy for electrical power purposes safe?


3) Can it be delivered at a reasonable cost?


4) How does it compare with other low-emission alternate energy sources?

Here is an overview only of those issues. But don't just take my word for it. Find out more yourself!

Emissions

• 
  Yes, nuclear energy is emission-free if you just measure the exhausts from a reactor's chimney.
  
• In one study, nuclear energy came close to wind power in low emissions over its lifetime.
  
• There is no air pollution, with big nuclear energy user France having the cleanest air in Europe.
  
• No, it is not emission-free and is a greenhouse gas emitter, when measuring mining of uranium and transporting it, building and decommissioning nuclear power plants.
  

Safe?

• 
  Chernobyl still stands the only disastrous accident with a nuclear power plant, and the antiquated structure and action taken after the "melt-down" bears much blame.
  
• Any safeguards are only as good as the people that manage them, and any further accident will be one too many.
  
• Modern nuclear power plant structures are much safer.
  
• A terrorist attack, using radioactive material in a dirty bomb cannot be excluded.
  
• A terrorist attack using an airplane could be disastrous, even though deactivating a modern nuclear plant can be done in 5 seconds.
  
• A higher-than-normal incidence of childhood leukemia has been reported near power plants in the UK, France and Germany.
  
• So-called Generation IV nuclear reactors, including "fast breeders" are said to be cleaner (low radiation level waste), cheaper and safer but the first will not be ready before 2010, some not until 2030.
  

Cost

• 
  Economics of nuclear energy is a wobbly concept, depending on the assumptions about other energy sources and their end costs.
  
• Nuclear reactors currently have very high start-up and close-down costs compared to other low-emission, and renewable energy sources.
  
• Costs are more than just counting money.
  

Comparison to low-emission energy sources

• 
  You'll find many studies with different results.
  
• One must take into account the urgent threat presented by global warming, that of radioactive energy, and appraise the benefits of energy-wise living and currently available renewable energy sources.
  

The magical attraction of nuclear energy remains: throw enough money at it and all our problems will seem to go away. But the future is most likely one of a diversified use of renewable energy with some nuclear energy. It's a question of where to put the emphasis.

Nuclear energy sources removes people even further from tangible "natural" processes. More of the same kind of thinking that caused our global warming problems in the first place. Why not emphasize responsible energy use, and the use of the Great Big Nuclear Reactor In The Sky to drive wind, tidal and solar energy. And to try and live in harmonious relationship with each other and our environments.

But you just have to make up your own mind. My children's future and yours depend on you. Only your personal attitude – the greatest energy source we know – can help you live with global warming. And we are going to have to live with it for a long, long time.

Elephant Dung May Stop Ivory Poaching

The ivory trade was banned several years ago, but poachers have continued to kill elephants for their prized tusks. These ivory tusks are made into valuable items like figurines and jewelry that are treasured by people all over the world. The unfortunate side effect of these poachers continuing to hunt and kill elephants for their tusks is that the population of African elephants dropped quickly from over 1 million just over one-half million in a short time period. Poaching is the illegal killing of elephants so that their tusks can be harvested and smuggled to other countries so that ivory products can be produced and sold for a great deal of money. Elephant dung may actually be the key to helping to control the number of poachers getting away with this crime in the name of the ivory trade. Knowing how elephant dung can help elephants is sure to pique the interest of anyone who loves elephants and nature.

Using elephant dung and elephant skin samples, scientists have been able to map the DNA of elephants. Because scientists can now use DNA to track where an elephant has been, they are using the technology to track elephant poachers. By using the elephant DNA, scientists can trace ivory shipments back to where the elephants were originally poached. If researchers find that a large number of poachings have occurred in the same area, law enforcement can be strengthened so that these poachers will be caught and prosecuted for their illegal activities. Using this technique to track elephants is almost like a jungle version of Crime Scene Investigation. Instead of using hair samples or skin cells from humans, these scientists are using DNA found in the dung and skin of the elephant to trace where they have been.

The presence of DNA in elephant dung is a great thing for researchers. Instead of having to collect skin samples, which would be a tedious and difficult process, they can take dung samples and use the DNA in those samples to track where elephants have been. Because elephants go to the bathroom up to 16 times per day, scientists involved in this effort have a lot of samples to choose from. It makes it a little easier for them to track the elephants when they keep finding evidence that leads them closer and closer to the scene of the poaching. This method is usually used to work backwards. Law enforcement officials may confiscate a shipment of ivory or arrest someone who is suspected of being involved in the ivory trade. The surrounding area is analyzed and investigators search for DNA. Instead of looking to find the killer where the ivory is, these scientists then backtrack, checking dung samples along the way for any signs of the same DNA. When DNA matching the DNA found at the scene of the ivory confiscation is found, they follow the trail until it loads to where an elephant was poached. This is a very interesting way scientists are using technology to help keep elephants safer.

How Many More People Can This Planet Hold Anyway?

Indeed, growth and development are to be expected and since the human race is breeding like rats the world over it has been estimated and we can expect some 50 Billion people walking the surface of the planet by 2050. Very few of the largest population centers will have the water resources they need.

Systems theory would dictate that we must build and prepare for the future that awaits and remove corruption or the Status Quo barriers which attempt to subdue change, which is a constant. Human populations need to stop breeding so fast and we must pay attention to what is going on, because if we fail to plan, then Mother Nature has another plan and one we most likely will not enjoy.

You see, it is irrelevant to Mother Earth what we choose to do, as there are cycles, patterns and things that just are. Today we have a choice, if we fail to choice that too is a choice. It appears we cannot count on government to fix the problem and the masses are far too demanding to choose. The collective of human consciousness is simply not going to work, we need strength of character and strong individuals to lead the way.

It is the unreasonable man which molds the world to his favor, not the group clinging to the old which is moving out of flavor. All hail the individual and the societies made of strength of character and individuals whose efforts bring change, upgrades to systems.

Defending a Nation Against US First Strike

If one were a betting man, then betting against the United States in war would be a lousy way to play it. There is no doubt that the stakes are very high for the defending nation and any mistake or failure to understand the opposing force and their ability to be "all knowing" in the modern battlespace bubble will result in severe losses and perhaps the most important defense barriers.

One new technology which will change and tilt the scale of favor slightly towards the defending nation are the new materials such as carbon composites and vehicles made out of predominantly nano-tube structure. Some current sensors on strike aircraft might have trouble finding them, however generally the targets, their locations and type are already pre-known prior to the striking aircraft's mission.

The goal in the first series of strikes is to eliminate Surface-to-Air threats and the US Navy and US Air Force are extremely proficient at this. Older hardware such as tanks, mobile missile launchers and vehicles made of steal really will not be able to maintain their concealment in today's battlefield.

Other strategies will also be considered by the defending nation; "If" the military mobile defense systems are made of hard to see materials and well hidden from view and will be to turn off all electronic and allow the engines to cool completely they will render little if any heat signature. Is it therefore possible for them to remain hidden?

Yes and No, if something sits too long it will show up as an anomaly on the Spy Satellite and if it moves too often it will have a heat signature and perhaps a CO2 plume which also shows up under various spectrums of light. What if the vehicles were electric?

Indeed, this makes sense too, but electric motors also get hot and take a little while to cool as well and they will need to power up a motor of some type at sometime to re-charge. Even if they were solar powered, they would still require large solar panels thus giving away their position.

This does somewhat remind us of the saying; "No where to run, no where to hide!" Of course this is the goal of the opposing strike force. When a defending nation is in such a position, it makes their political will and demands somewhat fruitless, as if push comes to shove and political impasse rears its head then there is always hell to pay.

An Australian Environmental Warrior-Up The Creek, Without A Paddle

Very soon the realisation of months of hard ground work will begin to unfold. After a long time planning, lobbying, preparing and training, kayak4earth, driven by one man, will set out on the Odyssey of a lifetime. The aim is to paddle the length of the Murray-Darling River System, from Brisbane to Adelaide. Due to climate changes and drought directly experienced here, this river system is now in danger of drying up. Indeed, there are long stretches of the Darling River, in particular, that are no longer flowing. Steve Posselt has attached wheels to the kayak, so that it may be towed it on his back through these sections.

This is one driven individual, by whose example and tenacity, sheer determination to be heard and commitment to a cause could shame us all. The purpose of this gargantuan effort is to consult and educate the public, councils and farmers about the need to conserve and make better use of the diminishing waterways. Frustrated by the lack of Governmental commitment and aid in relation to this very real threat, the kayak4earth team has decided to take to the waters and do something positive to bring awareness to the public. This is not a protest, but a statement and an exercise in education.

The Murray-Darling River System, is one of the largest produce regions in Australia, particularly, those areas along the Murrumbidgee-Murray. At the moment, unless some much needed rain falls in these catchment areas, farmers face the threat of being disconnected from the water sources which irrigate their crops. We are talking about a massive economic impact on the Australian population, not to mention devastating losses for our farmers. We have already experienced the effect of crop destruction due to cyclones in Far North Queensland. If better planning and management strategies are not put in place, Australia imminently faces a food shortage the like of which we have never known before. Rising salt tables pose a huge problem from over use in certain regions, rendering them non-arable areas. Now we face the dilemma of no water flow.

Borne of a lifetime of living and working in the water industry, faced with continuous apathy and lack of awareness, the aim is to bring change to the thinking of the Politicians of Australia, to the regional councils and public in relation to Climate Change and water management policies.

Such a huge personal commitment from a citizen to rally and actively involve himself in the process of education and awareness, is an awesome undertaking. Were we all so personally driven and involved, perhaps our environment would stand a better chance of recovery and conservation. Should we not all have the impetus to make such a sacrifice?

Steve is another Australian Environmental Hero. One can only hope that his efforts are rewarded with recognition, both of the problems we face as a nation and the unbelievable stretch of personal endurance and commitment his odyssey will demand of him. The Australian Government will stand to learn a lot from this exercise. as scientific analysis and planning strategies will be formed along the way.

Do Not Brag About Being a Christian to Your Atheist Boss

Many people are very proud of their religion and go out of their way to tell people that they are in good moral standing due to their religion. This is excellent that they feel this way, but one word of advice - Do Not Brag About Being a Christian to Your Atheist Boss.

You see often atheists believe that those who are of a strong religious background use it as a crutch. Atheists see believers as those with weak moral values, needing a religion to remind them what is right and what is wrong. It is interesting that folks believe that one needs to be a certain religion to have a moral foundation. An atheist might say; That is the most silly comment I have ever heard?

The atheist believes that this comment about believers having a moral foundation above the rest is absolutely ridiculous, indeed it is the exact opposite in their opinion. They reason that if you need a religion to help you know right from wrong, then you do not have an actual moral foundation of self, but it comes from an external source of fear of a god or denial of heaven or fear of hell or not getting free toys from Santa.

The atheist does not see why others cannot see this, as they say it is so obvious. You are either good or bad, regardless of the team you play on or religion you believe. Perhaps this will help you understand your atheist boss and understand why he believes you have low-self-esteem and a problematic personal character and ethics boundary.

Bottled Water Industry Takes Off as Environment Suffers

The Bottled Water Industry has seen nothing but record profits in the last five years. Each year more and more companies enter the market and each year the environment suffers more and more. Although the plastic bottles are recyclable and fast decaying in the environment, it just is not fast enough it seems. Indeed, when was the last time you went for a hike or a jog. How many littered empty water bottles did you see?

This is now happening all around the World and it is getting to be a completely problematic issue. Of course the bottled water industry is a very high profit business, so much so that you would think they would go out of their way to protect it, by encouraging folks to not litter. The industry has put forth PR initiatives but very little has actually been done.

Now mind you that I am not environmentalist, far from it, but it sickens me to see all this trash, it is as if no one cares. Do you care? Yes or No? Well, how many empty water bottles did you pick up today? In the last five years bottled water usage has nearly doubled states the research from environmental groups, yet they claim only 21% of the bottles reach the recycling system.

Not only are these empty water bottles not making it into the recycling system, fewer than 65% ever make it into a trash can and mind you in many countries there are no trash services. Where does it all go or do you really want to know?
