Prior to the Olympics in Beijing, China solved a pollution problem they previously claimed they never had by banning all cars except those for communist party elites. It did little for CO2, Beijing had a PM10 (smog) problem, but it showed drastic interventions could help the air.
If a school doesn't have a strong sports program, universities that have seen faculty and administrative salaries skyrocket have used the unlimited student loan debt program created in the late 1980s to fund growth. Yet a few years prior to that, a science fundraising option had also been made available.

In 1980, Democrats passed the Bayh-Dole Act and it reversed long-standing policy that if a discovery was made using taxpayer-funding, it could not be privately monetized. It became possible for scientists who did applied work to start a company or sell a patent so a corporation even if the American people had paid for it.
Obesity is closing in on smoking and alcohol as the top killer among lifestyle diseases. Over 25 percent of the world is overweight and in countries like the UK and US, that number is approaching 70 percent. It is correlated to things like heart disease.

 In 2019, nearly 12 percent of Black individuals experienced pre-term births compared with 7 percent of White individuals, according to a new demography paper.
Most opioid addicts are recreational users, not those who started on prescription pain medication and continued to have pain and migrated to illegal routes when doctors behaved ethically and shut them off. It just makes people feel good. It is no surprise that opioids are involved in far more deaths each year than guns. If opiods were legally available without a prescription, they'd be in the same category as alcohol when it comes to lifestyle killers. That is what addiction does.
