Drawing on a wide range of sources, the institute's latest Vital Signs report shows trends related to today's often record-breaking levels of consumption by providing data and concise analyses of significant global trends in food and agriculture, population and society, and energy and climate.

 "Consumers often do not know the full footprint of the products they are buying, such as the embedded water in a t-shirt or steak, the pesticide exposure of cotton farmers, or the local devastation caused by timber companies cutting down forests to produce paper," says Michael Renner, Vital Signs project director.

 The 24 trends tracked in Vital Signs illustrate these and other consequences of consumption on a scale never before experienced on Earth. With a global population of over 7 billion and growing, the need to preserve ecosystems is undeniable. Yet, for many products, the growth of consumption is reaching new levels:

Global meat production has more than quadrupled in the last half century to over 308 million tons in 2013, bringing with it considerable environmental and health costs due to its large-scale draw on water, feedgrains, antibiotics, and grazing land.

Coffee production has doubled since the early 1960s. However, an estimated 25 million coffee growers worldwide are at the mercy of extreme price volatility.

For more than 50 years, global plastic production has continued to rise, with 299 million tons of plastics produced in 2013 alone. Recycling rates remain low, however, and the majority of plastics end up in landfills and ocean-polluting ecosystems, entangling wildlife, and blighting communities.

The world's fleet of automobiles now surpasses 1 billion, with each vehicle contributing greenhouse gases and reducing air quality.

"Untrammeled consumerism lies at the heart of many of these challenges," writes Renner. "As various articles in this edition of Vital Signs show, consumption choices matter greatly."
