Changes

* Environmentalists have been opposed to [[nuclear power]] since the 1970s.  Their cause gained more public support after the 1979 [[Three Mile Island]] accident.  As a result of this opposition, no new nuclear power plants have been commissioned in the United States since.  In conjunction with Carter's energy policy, this led to coal becoming the default electricity-producing fuel.  See above for the consequences.  Nuclear power, by contrast, does not produce any air pollution at all.

* [[Aerosol]]s are known to have an atmospheric cooling effect, possibly masking any man-made warming effects from greenhouse gases, assuming there is such a thing.<ref>http://www.enn.com/pollution/article/39303</ref>  Liberal environmentalists campaigned heavily against consumer use of aerosols starting in 1974 after an environmental scare hit the news that aerosol sprays could be harmful to the [[ozone layer]].<ref>http://www.predictweather.co.nz/assets/articles/article_resources.php?id=36</ref>  See above for the consequences.  Global mean temperatures began rising again in the late 1970s.

* The [[anti-DDT campaign]] leading to a ban on [[DDT]] on most places has led to millions of deaths from [[malaria]] in the developing world.<ref>Murray, Iain.  ''The Really Inconvenient Truths''.  Regnery Publishing, 2008.</ref> The popularity of Rachel Carson's ''[[Silent Spring]]'' was a significant factor in bringing about a ban on the use of DDT.  Replacement pesticides adopted after the DDT ban have proven to be less effective at eradicating [[mosquito]]es, and more harmful to the environment.  When properly used DDT's ecological impact is negligible.<ref>Lomborg, Bjorn.  ''Cool It'', pg 98.  Vintage Books, 2008.</ref>

* Liberal [[immigration]] policies adopted in the United States due to the passage of the 1965 Immigration Act, opened the floodgates to unsustainable population growth in the United States which continues to this day.  Had immigration levels been left at pre-1965 levels, U.S. population would have likely stabilized at around 240 million by now.  Instead it is over 300 million, and expected to reach 468 million by the year 2060<ref>http://www.cis.org/impact_on_population.html</ref>, mostly due to mass immigration.  The U.S. ecology cannot handle this rate of population growth.<ref>http://balance.org/alerts/alert122004.html</ref>

* Likewise, the ecology of U.S. National Parks and Monuments bordering [[Mexico]] has been trampled and is severely at risk from the [[illegal alien]]s coming into the U.S. who enter through those parks (such as Organ Pipe Cactus National Monument).  Liberal environmental groups responded to this threat, not by supporting the [[The Secure the Fence Act of 2006|border fence]], but by filing lawsuits against the fence claiming it would disrupt [[animal]] habitats.  When in fact, the flood of illegal aliens already did disrupt those animal habitats.<ref>http://www.desertinvasion.us/</ref>
