What we make and buy is a major indicator of society’s collective priorities. Among twenty-four key trends, Vital Signs Volume 22 explores significant global patterns in production and consumption. The result is a fascinating snapshot of how we invest our resources and the implications for the world’s well-being.
The book examines developments in six main areas: energy, environment and climate, transportation, food and agriculture, global economy and resources, and population and society.  Readers will learn how aquaculture is making gains on wild fish catches, where high speed rail is accelerating, why plastic production is on the rise, who is escaping chronic hunger, and who is still suffering.
Researchers at the Worldwatch Institute not only provide the most up-to-date statistics, but put them in context. The analysis in Vital Signs teaches us both about our current priorities and how they could be shaped to create a better future. 

This book will be especially useful for policymakers, environmental nonprofits, and students of environmental studies, sustainability, or economics.

Further highlights:

  • Aquaculture production has increased about 10-fold since 1984; today, almost half of the fish people eat are farmed.
  • China has built the world's largest network of high-speed rail, accounting for 40 percent of high-speed travel in 2013.
  • In the United States, only 9 percent of plastic was recycled in 2012; the rest makes up nearly 13 percent of the solid waste stream.
  • Coffee production is near record levels today, though prices remain volatile.
  • While global hunger is decreasing, 1 in 9 people still do not get enough to eat.
