There is this pending catastrophe of global warming, but precious little action being taken to reduce our fossil fuel emissions. A much greater urgency is required at this time as the Greenland Ice Sheet is about to slip into the ocean and raise sea levels by a significant amount, displacing millions of people dwelling near the coastal areas.

Meanwhile, Earth's 946 $Billionaires are "the least concerned" about global warming, because they can handle it, they can buy what they need to survive any catastrophe. Also, they are causing it with their financial decisions, and they have the ability to do the most about it.

The poor will suffer the most, and they are the people with the fewest emissions that cause global warming. From the outside, it might look like the Final Act in global domination by the Wealthy Elites as the poor are killed off by global warming. From our viewpoint, however, it just looks like our pollution is coming to get us.

People have long termed those engaged in preserving the natural world as 'environmentalists.' This label is preposterous. As humanity destroys its home, we should be calling those engaged in preserving the natural world at least human rights activists, humanitarians and at most heros in this war to save future generations from risk and the tragedy of unsafe, unreliable resources that support the basic levels of human rights. The war Sir David Attenborough has joined is for much more than global warming. But who is fighting this war, and how do you tell what side you are on? Who is fighting in this war?

Humanitarians, those fighting for human rights, environmentalists, forward thinking politicians, such as Tony Blair or Stephan Dion, and many aboriginal groups around the world, loosely consist of one side; the good guys seeking to preserve our planet and our lives. The opposing side are the unsustainable industries raping the planet for short-term profit: big-oil, big-lumber, big-mining, other industry, supported by politicians like George Bush and Stephen Harper.

We should tell the story like it is: the good guys fight to preserve life on earth. The bad guys fight to keep destroying life for thier immediate profit. Like the Nazis were beaten for a better future, so too must be unsustainable industry. The battle cry is not for global warming. It is for the health, safety and freedom of humanity.

How does a Canadian know which side they are on? No North American can justify ignorance or disbelief of the environmental crisis that beleagers us now. If a person is not living as sustainably as they can, minimizing waste, utilities use, pollution, meat eating, oil consumption, among other things, then this person is on the side of those raping the planet, the unsustaianble side, destroying our future health, freedom and prosperity. The side that must be stopped.

Canadians especially need to realize this, and choose which side they are on. It great that Sir David Attenborough has added his voice to the battle cry. Canadians must also be expected to add thiers to one side or another, and in doing so chose which future to fight for.

Very likely the most damaging eco-process happening in the world today is the projected increase of 3.5 billion souls added to the present 6.5 by 2050.

Nothing any one could possibly do in terms of curbing energy use could possibly offset this reality.

Further Canada is on track to migrate 300,000 people from sub-saharan climes to sub-artic climes in a country that happens to be the most energy imtensive country in the world per capita.

Al Gore, David Suzuki and now Richard Attenborough care of the passionate eye have all added their two cents worth but through fear of stepping outside the boundaries of the politically correct, ignore population growth and more importantly the negtaive global footprint that population growth in countries like Canada can make.

With all the experts out there someone please have the courage to do the mathematics of what it means in terms of global warming when the populatiom of India surpasses China and what it means to bring a single Indian family from temperate climates to a sub-artic energy intensive country such as Canada. Or is this still to politically incorrect to discuss!!!!!!!!!!!!!!

Corporate tobacco manufactured a cancer epidemic

The fast, fat, sugar contaminated food corporations have manufactured an epidemic of illness.

Now the carbon corporations of coal electrical generating, the automobile corporations and urban sprawl developers are fooling million with their ads that this is acceptable behavious of cool, powerful, intelligent, sexy people. But more and more leader are waking up to the lies.

The leaders of Enron were found guilty of financial accounting fraud. The CEOs of the Tar sands must be pursued for having committed scientific accounting fraud to justify massive increase in greenhouse gasses. While lying as to the human mental and physical, the economic and environmental impact of destabilizing a planets climate.

After watching the first episode "Can We Save Planet Earth?" my only question is why isn't this brilliantly made series on DVD and widely distributed to the public? All students should have a copy of this to take home for their families to watch, libraries should have copies, and it should be made available to all movie store outlets. Mass collaboration on this issue is the key!

Previous comments reveal a fear of population growth, migration of peoples from warmer latitudes to Canada, and the attendant energy consumption. Nowhere did I find a reference to clean, GHG emission-free CANDU nuclear power, or electric cars.

Submitting that we can use energy somewhat liberally whilst being good stewards of the biosphere, I stand behind CANDU nuclear power. Electric-based transport then becomes almost emissions-free.

The power to save our planet is within our reach both technologically, and socio-demographically; what remains doubtful is the question of overcoming an anti-nuclear bias that slows the deployment of this key pillar of biosphere preservation - to the detriment of all creatures, not just us humans.

Technically speaking, Plug-In Hybrid Electric Vehicles are an unnecessary precursor to battery EV's; nonetheless, for various socio-political reasons, they present a good opportunity to roll-out a substantial fleet of vehicles equipped with electric drive.

Here's a tipping point worth noting. When market penetration of PHEV's (& all EV's) reaches a certain point, the mass appeal of driving in electric mode - at 1/10th the cost of gasoline for the first 100 km driven after a nighttime charge - will create a sustained demand for electric transport.

In addition to nuclear power, the smaller-scale initiatives of wind and solar should also be pushed as the "micro-power" slice of the electricity generation pie. An optimistic analysis of this mix is treated well in Vijay Vaitheeswaran's recent book "Power To The People".

EV's present an opportunity to solve 25% of the GHG emissions problem: transportation. Wider adoption of nuclear power, in preference over fossil-fired stations, will do further good.

Any pessimism I harbour as to the global warming threat doesn't stem from doubts related to our technological prowess; rather, I fear that we won't reach the tipping point whereupon we conquer a pervasive anti-nuclear bias that inhibits our collective will to adopt this readily available solution to the global warming crisis.

Wow! I just watched the documentary and asked my 8yr old son to watch it with my better Half and I. Wow! The way you showed the the carbon dioxide entering the atmosphere in tiny little black squares was awsome. That was the perfect way to open an eight years olds eyes to exactly how much damage we are doing to the planet. I watched the expressions on his face as I watched the documentary and was amazed how concerned he was about that "big black cloud" above the Carbons home.

I am proud to say that my family has already started to make drastic changes as well, after watching the documentary by Al Gore "An Inconvenient Truth" , but your approach was simple and to the point. I as well think that this documentary should quickly be put into school circulation. I know for a fact that it made my eight yr old begin to think a little more about the world he will be facing when he matures. My hats off to u guys.

Being able to purchase episodes of this show needs to be an option for viewers, especially after this episode.

Unfortunately the CBC has only purchased broadcast rights to this series as it was produced by the BBC.

We don't have any purchase information at this time. Sorry about that...
