Why Patrick Moore Left Greenpeace....

More reasons to loath Greenpeace....

The breaking point was a Greenpeace decision to support a world-wide ban on chlorine. Science shows that adding chlorine to drinking water was the biggest advance in the history of public health, virtually eradicating water-borne diseases such as cholera. And the majority of our pharmaceuticals are based on chlorine chemistry. Simply put, chlorine is essential for our health.

My former colleagues ignored science and supported the ban, forcing my departure. Despite science concluding no known health risks – and ample benefits – from chlorine in drinking water, Greenpeace and other environmental groups have opposed its use for more than 20 years.

Opposition to the use of chemicals such as chlorine is part of a broader hostility to the use of industrial chemicals. Rachel Carson's 1962 book, "Silent Spring," had a significant impact on many pioneers of the green movement. The book raised concerns, many rooted in science, about the risks and negative environmental impact associated with the overuse of chemicals. But the initial healthy skepticism hardened into a mindset that treats virtually all industrial use of chemicals with suspicion.

Sadly, Greenpeace has evolved into an organization of extremism and politically motivated agendas. Its antichlorination campaign failed, only to be followed by a campaign against polyvinyl chloride.

Greenpeace now has a new target called phthalates (pronounced thal-ates). These are chemical compounds that make plastics flexible. They are found in everything from hospital equipment such as IV bags and tubes, to children's toys and shower curtains. They are among the most practical chemical compounds in existence.

Phthalates are the new bogeyman. These chemicals make easy targets since they are hard to understand and difficult to pronounce. Commonly used phthalates, such as diisononyl phthalate (DINP), have been used in everyday products for decades with no evidence of human harm. DINP is the primary plasticizer used in toys. It has been tested by multiple government and independent evaluators, and found to be safe.

Despite this, a political campaign that rejects science is pressuring companies and the public to reject the use of DINP. Retailers such as Wal-Mart and Toys "R" Us are switching to phthalate-free products to avoid public pressure.
