It is not silly to think that when polar bears become extinct,  that the human race won’t be shortly behind them; therefore, preserving the environment for the polar bears is of utmost importance.  As well as the high CO2 levels melting the ice, all the oil in the ocean undermines the polar bears food supply and when the polar bears food supply is undermined, so are the humans food supply.  Greed overlooks facts.

That’s all the world needs, more ‘hopeful’ online articles!

Yes, I do believe in the chance that we can change and make a positive difference.. no, I don’t rely on magical ‘hopeful’ thinking.

Adios!

Forget polar bears?? NEVER!! Shame on Truthdig! This in a nutshell illustrates the hubris of humans, who always put themselves first and can so quickly dispense with any concern for other endangered - and non-endangered - species. This is exactly why we have these kinds of monumental environmental disasters. Long live polar bears!

The article would have been much better if they had included their methodology of how the numbers were attained. Was it in a controlled setting where you deplete the oxygen levels while raising the carbon dioxide levels? If we don’t know how they reached their numbers, it becomes just another of the millions of poorly written scare tactics.

This is a typical gloom-and-doom article. The amount of CO2 needed to start harming plants would have us killed off before we could worry about the plants. TD, stop trying to terrify everyone with vague threats.

I seriously suggest to Truthdig editors that they do some research online and find some worthy articles with a more hopeful tone. The amount of pessimism in present choices is overwhelming and militates, I think, against empowering people to do anything more than moan and groan. In the back of my mind I know of significant steps that are being taken toward “saving the world” and mitigating the coming crisis of corporate capitalism. 

Of course there is a lot of “end of time” religious junk listed under broad headings like “hope for the future” but if one can wade through it, there is other worthwhile thinking and action going on—albeit on a small scale, usually. Stuff like Fromthewilderness.com and survivingpeakoil.com turned up for me in just a few minutes, as examples.

Maybe I’m wrong, but I just can’t tolerate so much negative feedback and accept it as “balanced.”

The over population of the planet demanding ever increasing amounts of every ressource available is a problem that must be faced. 
If religions continue to brow beat people into a so called reproductive mode they are just sawing off the branch on which they are sitting.
We will probably either kill each other or be culled by some new fast spreading disease.
Our present state is unsustainable.

The Right-Wing Corporate Conservative fascist Right-Wing Republican corporations’ socialist monopoly is only concerned about profit, capital, and money; killing the environment where the environment is no longer a habitat for humanity is the CEO’s profit agenda; protection of the environment for the non-human corporations, although run by humans, is not in the CEO’s repertoire.

whoohoo!
