The comment about alternative fuel sources such as biofuels from plants ( Item No $4 Plant Power) is not a method of saving the planet. It will continue to rush the planet to extinction.The process of burning any fuel means the consuming of oxygen to support the combustion process. The generation of carbon and the massive consumption of oxygen musy be totally stopped. No oxygen, no life. Alternative energy sources must be either, wind, tidal, sea water hydro from damming coves and bays along the coast, and solar . These energy sources do not use oxygen .

Ten ways to save the planet should have listed the following. Reduce population numbers by 75 %, stop using the process of combustion to generate energy, stop deforestation, stop pouring sewerage into the rivers and oceans, stop over fishing, stop resources depletion such as iron ore and other minerals, stop the eradication of species, stop business from running the environmental agenda, start educating the public about oygen usage, stop concentrating solely on carbon emissions as the solution to our problems environmentally

i think i see a way out of this... and we can turn the world on its head... africa and all equatorial countries have a surfiet of the best source of energy on the planet .... sun. The technology exists for the equatorial countries of the world to supply energy to the rest of us..but fortunatley for the neocons and the economic giants.it seems they are just cant be bothered.

The problem I see is that the Global warming types want to focus only on solutions that involve redistribution of global wealth. They downplay any solution that does not do this.

I find that odd! They call this the greatest threat to mankind, that we have to act now to save the world. But then are not willing to look at all possible solutions. Just ones that also happen to have other socio-economic outcomes. That seems a little odd to me!

Unless what they are really seeking are those "other socio-economc" outcomes!

And just a side comment. Wind, solar, tidal power? Doesn't all that "energy" already do something in nature? Don't all three of those play a role already in global weather? So why should we think that tapping into that energy will not also have a global weather impact?

You can not just take energy out of an existing system and then expect no change to that system!
