&gt; <i>We have eliminated some diseases. But we have also created new, much horrible and powerful ones. We have discovered antibiotics, but that have also created disease causing agents that are resistant to them.</i><p>&gt; <i>When ever we change something fundamental, that has resulted in the creation of much bigger evil.</i><p>I disagree with the assertion. Sure, sometimes we screwed things up big time (e.g. climate), but sometimes the change really was for the better. For instance, even though we&#x27;re facing super-germs, life is <i>much</i> better for everyone than before we had antibiotics. Sure, we may end up defeated by the resistant germs, but it&#x27;s not certain - that&#x27;s why we have to push science and technology further, develop new methods like bacteriophages, because we <i>can</i> keep up with nature and have it our, better way.<p>&gt; <i>I think this is because we don&#x27;t have capability to see the whole picture. We look at a small portion of it and think. &quot;hey, we can make it better&quot;. But ends up messing up the bigger picture making it grotesque. So my point is, this is not an easy decision that should be made so lightly.</i><p>That I will agree with. We often suck at seeing the bigger picture. That doesn&#x27;t mean we&#x27;re screwed, because a lot of things can be dynamically adjusted and fixed as needed, but it does mean we should be careful with significant interventions into established systems. Death itself, for instance, is something that underpins a lot of our social structures and systems, so it is something we need to be extra careful about, but it doesn&#x27;t mean we can&#x27;t, or shouldn&#x27;t change it.
