Adapting to a world with people "walking around three feet tall"

The pygmies on this old photograph show  the  size  of most  people in the future,  if  one  is to believe  recent studies

Humans and other mammals as well as a lot of other living creatures are going to shrink dramatically because of human caused global warming, if we are to believe a number of recent studies.The newest shrinkers are 600 types of marine fish, which are about to dwindle up to 24% between 2000 and 2050, according to a report published in the journal Nature Climate Change. 

Warmist scaremongers of course are telling us that shrinking will cause all kind of calamities for humankind. A L.A. Times writer e.g. thinks that "Fewer, smaller fish could result in a supply crunch, leading to higher prices of seafood down the line." However, Philip Gingerich, the researcher who first looked into shrinking animals during the PETM (Paleocene-Eocene Thermal Maximum) does not see any reason to worry too much about a shrinking humanity:

"I joke about this all the time - we’re going to be walking around three feet tall if we keep going the way we’re going,” Gingerich, of the University of Michigan, said. “Maybe that’s not all bad and if that’s the worst it gets, it will be fine. You can either adapt, or you go extinct, or you can move, and there’s not a lot of place to move anymore, so I think it’s a matter of adaptation and becoming smaller.”

And in fact, a shrinking world population might not be a bad thing. Other scientists have suggested that getting a lot smaller might help with other global problems, like the fact that we're running out of food and using up too much fossil fuels to drag our obese selves around, thereby releasing too much carbon dioxide.

PS

However, adaptation to a world with ten billion pygmy sized people will not always be that easy. What will e.g. be the future of the NBA, now relying on players as tall as 7'7" (2.31 m)? It will probably be a whole new ballgame with three feet tall players! :)
