This seems like this is going too far in the other direction. The news is often very negative but that's because we don't have headlines like "Last month, more solar power was installed than any other week in history, again for the 40th month in a row." Similarly, many diseases that were death sentences a few years ago have with the advance of modern drugs been turned into manageable illnesses. Cystic fibrosis for example used to kill early almost everyone who has it. Now we have drugs which make people with it likely to have lifespans close to normal. Similarly, HIV invariably lead to AIDS and a functional death sentence within a few years. Modern HIV treatments give people with HIV life expectancies better than a typical person in the 1950s. Lots of positive things are happening even as lots of negative thing are happening also.
