All I am saying is that this idea that CO2 is the big(gest) polluter, is not only false,but dangerous, because people/industry, can claim it is going green and people will buy the product or otherwise, but in reality going green only meant they reduced the carbon “foot print” but they will keep releasing or release new pollutants (I am looking at you CFLs).
RE CFLs what I understand is that the mercury released from air pollution for powering incandescent bulbs (thru burning fossil fuels) over less power needed for CFLs is greater than the mercury that ends up in the environment from peole who inappropriately disposed of their CFLs. See

But you raise a very valid concern – some of the solutions also have risks and harms. And this is a very good topic for this thread.
We want to do the right thing to mitigate climate change, but we need follow a holistic approach and consider ALL the negatives and positives of the alternatives v. all the negatives and positives of conventional measures.
In addition to those fossil fuels which release mercury when burnt (which has been decreasing due to EPA regs), they also release other local and regional pollutants that harm and kill, such as miscarriages. Just read this about health consequences of coal burning:
wwwp.dailyclimate.org/tdc-newsroom/2013/03/coal-health-costs. And there are cancer alleys in places where oil is processed, oil spill harms, and also harms from mountaintop removal for coal and from coal ash spills (like in Tennessee – see
en.wikipedia.org/wiki/Kingston_Fossil_Plant_coal_fly_ash_slurry_spill
Even with nuclear there are harms and dangers, starting with uranium mining wreaking havoc for local peoples and miners, then the risk of disasters such as Fukushima, and where to deposit spent uranium and radioactive waste. I know nuke power has been proposed as a way to mitigate AGW, and many “warmers” promote it. I am not totally againt nuke power, but we need to look at it holistically. Are there more GHGs involved from cradle to grave in the nuclear power production chain than in burning fossil fuels? And we also need to do much much better to safeguard the health and well-being of uranium miners and locals in mining areas, and make sure nuke plants are safer, and address the disposal issue (and possibilities of dirty bombs, etc). Also the (usually coal) peaking plants needed to supplement nuke power in peak electricity times (which amounts to about 25% of the energy mix), since nukes have to run at a fairly constant level. For instance, the energy nukes generate on off-time could be “stored,” e.g., by pumping water into a higher reservoir, then releasing it as hydro-power during peak hours, etc., reducing or eliminating coal peaking operations.
People against wind power often bring up bird kills (which are a very tiny fraction of bird kills from other human activities and from cats), but compared to what? GW, exascerbated by fossil fuel burning, is expected to make over 50% of bird species go extinct by next century, and is already harming birds in various ways. And the other pollutants from extracting, processing, burning, and spilling fossil fuels also harms birds in various ways. Also, I’ve read the wind power people are working on measures to reduce bird kills, like radar detecting migrating flocks and shutting down the wind-generators, and locating wind generators in less bird-sensitive areas.
Probably the the most important thing we can do re the negative side-effects of all these energy sources is to to reduce our energy usage, which can be done in ways that do not reduce our living standards. That is step one, REDUCE.
When they ask “paper” or “plastic” in the check-out line, we could be presenting our own reusable bags, REUSE.
So doing the EC (environmentally correct) thing is not always a matter of “somewhat less harmful A” v. “somewhat more harmful B,” because there is often C, D, and so on that are even much more benign alternatives.
RE CFLs, they now have “super-low” mercury CFLs (see
allegroshops.com/bulbrite-industries-cf13sd-lm-13w-super-mini-low-mercury-compact-fluorescent-coil-soft-daylight-set-of-12-509114.html?gclid=COjzusWoibYCFWamPAodN2MA6w).
Also I’ve heard they are doing better with LED lights now – making them less eye-blinding, softer & warmer with more natural glow.
Bless all who seek to be part of the solution.
