 However, there's no particular reason to think that the fossil fuel industry is
 irrational or unscientific. In fact, fossil fuel companies are some of the
-world's most scientifically capable organisations. Fossil fuel extraction makes
-intensive use of technological and scientific resources, from the geological
-surveying needed to identify reserves to the hydraulic engineering needed to
-pump gas and oil from underground or subsea reservoirs. Despite these

 Even the production of so-called 'fake science' can be seen as the result of the
 fossil fuel industry acting rationally on the basis of the scientific evidence.
