GR: By 2050, our global population will increase by more than 2 billion people. That’s if nothing gets in the way. The projected growth comes at a time when the Earth’s capacity to support us is in decline. Add the increasingly fierce storms of an unbalanced climate system to the problems of dwindling resources, and calamity becomes unavoidable. It’s too late to rebuild Earth’s food-producing ecosystems, prevent climate upheaval, or control our reproductive urges in time to avoid disaster, but we can prepare for the inevitable crash. Those of us who can’t stuff our pockets with oil money can use our minds instead and begin studying the options.

Here’s a link to the U. S. Census Bureau’s population clock :  https://www.census.gov/popclock.

“The global population will reach 9.8 billion in 2050, up from 7.5 billion now, according to the 2017 World Population Data Sheet. This year’s edition includes a special focus on the world’s youth (ages 15-24), with indicators and analytical graphics that assess whether youth are poised to become productive adults.” –2017 World Population Data Sheet (Population Reference Bureau)

GR:  I just ran across another good discussion by Richard Heinberg (http://www.postcarbon.org/why-climate-change-isnt-our-biggest-environmental-problem-and-why-technology-wont-save-us). It’s certainly worth a read.
