Alan F wrote a good essay about this, which can be accessed off Randy Waters' site. Some stuff I recall, or have read elsewhere:
Human life span has increased dramatically in the past 100 years, as many childhood diseases have been either wiped out or successfully treated and prevented.
Pollution is on the decrease, as cars become cleaner burning, lead has been removed from gasoline, and scrubbers have been installed on factory smoke stacks. Also, cleaner fuel alternatives such as wind power and fuel cells and hybrid electric cars are nowunder development.
Man has studied damage to the ozone layer and has removed products containing ozone damaging chemicals, such as A/C refrigerant.
Medical treatments make many sugeries much less painful or unecessary. Advances continue to be made, and the sequencing of the human genome holds out prospects for still better treatments in the future.
Minorities and women have gained rights all over the world, something Mrs Q just commented on.
Sure, there's still some bad stuff going on. Crime is still a big problem. Terrorism is very scary (but so was the Cold War). But overall, I'd much rather be alive now than in Pastor Russell's time.
