Nature does not know best. The vast majority all species in history have been wiped out by their natural environments, many by their &lt;i&gt;own genes&lt;/i&gt;.&lt;p&gt;&lt;i&gt;All&lt;/i&gt; actions that we take to try to fix problems go on to create new problems. It&apos;s expected.&lt;p&gt;And, of course, this doesn&apos;t mean we shouldn&apos;t act, unless we have a good explanation &lt;i&gt;now&lt;/i&gt; as to why the harm of a proposed course of action outweighs the benefits.&lt;p&gt;The alternative is to follow some kind of &apos;Precautionary Principle&apos;, which, as David Deutsch has pointed out, can only damage our ability to handle threats which we do not foresee.&lt;p&gt;Meanwhile, people&apos;s lives are in known peril from malaria.</text><parent_chain><item><author>0x12</author><text>&lt;a href=&quot;http://www.nature.com/news/2010/100721/full/466432a.html&quot; rel=&quot;nofollow&quot;&gt;http://www.nature.com/news/2010/100721/full/466432a.html&lt;/a&gt;&lt;p&gt;Makes a good case for why eradicating mosquitoes will not be problematic.&lt;p&gt;But every time there is a large scale intervention like this the side effects only become apparent decades after the fact.
