I've always wondered why you never hear about biotech or pharmaceutical companies buying up land with high biodiversity such as rainforests. Natural selection has been operating a trial and error laboratory running 24/7 for over 3 billion years accumulating DNA that by definition is useful for living organisms. Its just waiting there being slowly destroyed for short-term resources like wood and oil. Resources we already know won't be viable products within decades. If you look at medicine some of the most pivotal drugs like opioids and antibiotics were discovered rather than created. Even with the inability to patent naturally occuring genes I can't fathom how much R&D could leapfrog forward in a profitable way.
