Tug-of-War between Carrying Capacity and Rising Demand—Can We Keep This Up?

Energy

Worldwatch Institute

The global economy continued to grow last year, world population surpassed 7 billion and the use of energy and other natural resources generally rose. The Worldwatch Institute captures the impacts of this rising consumption and the increasingly risky state of humanity in Vital Signs 2012, the latest compilation of indicators from the Institute’s Vital Signs project. The Washington, D.C.-based environmental publisher Island Press released the book today as part of a new partnership with Worldwatch.

Vital Signs 2012 provides up-to-date figures on our most important global concerns. Drawing from international agencies and organizations and from Worldwatch’s own research, the report provides authoritative data and analysis on some of the most significant global trends, including population growth, renewable energy production and oil consumption.  

“The information showcased in Vital Signs 2012 will inform governments, policymakers, NGOs and individuals about the current state of the world’s consumption patterns, economic priorities and environmental health, allowing for more well-informed policies and decision making,” said Michael Renner, Worldwatch senior researcher and director of the Vital Signs project. “Commitments are needed to reverse a number of harmful trends.”

Population growth combined with rising resource use, heavily tilted toward the world’s wealthy on a per capita basis but growing rapidly among the expanding global middle class, is reflected in rising worldwide resource consumption. Oil use reached an all-time high of 87.4 million barrels a day in 2011. Meat consumption increased 2.6 percent in 2010. Growing demand for timber translated into forested areas shrinking by 1.3 percent, or 520,000 square kilometers, from 2000 to 2010—an area roughly the size of France.

“The story that resource consumption is rising is hardly new,” said Worldwatch President Robert Engelman. “In fact, it’s an ongoing challenge to keep that critically important story fresh and interesting. But these rising trends will not last forever. They can’t. Their continued growth in our lifetimes reminds us how urgent it is to develop new ways of assuring decent lives and livelihoods for all—ones that do not result in increasingly negative impacts on the people and world around us.” 

The use of biofuels, for example, can play a role in the transition to more sustainable lifestyles. The U.S. is the global leader in corn-based ethanol, yielding 49 billion liters annually, or 57 percent of the world output. Yet demand for this renewable energy source is a double-edged sword. Under the right circumstances, biofuels can be a less carbon-intensive alternative to fossil fuels. But using corn to make biofuels comes at the expense of its availability to be consumed as food, and rising demand for ethanol has pushed up the price of staple grains. In April 2011, the Cereal Price Index hit a record high of 265, reflecting a 5 percent price jump worldwide.

Vital Signs 2012 also highlights the rising consumption of animal protein, as well as destructive industrial livestock practices that help make this growth possible. As more people in developing countries enter the middle class, meat consumption is rising and the intake of processed meat is shifting to unhealthy levels. Meanwhile, the expansion of factory farming to meet increasing meat demand fosters the spread of diseases such as avian influenza, swine flu and mad cow disease.

Not all of the trends highlighted in the report are cause for concern, however. Increasing demand for more time-efficient transportation systems has led a growing number of countries to invest in high-speed trains, which release 80 to 120 fewer grams of carbon dioxide per passenger-kilometer than automobiles do. High-speed trains demonstrate how environmental efficiency can be congruent with consumer convenience.  

Vital Signs 2012 analyzes the aforementioned trends and many more, using straightforward language and easy-to-read charts to explain global trends to governments, businesses and consumers, helping them to make more informed decisions for our future.

Further highlights from the report:

  • Organic agriculture: Challenges such as rising farmland prices, inconsistencies in organic standards, and higher prices of organic foods continue to impede a broad global shift to sustainable agriculture.
  • Overweight and obesity: A survey of statistics in 177 countries shows that 38 percent of adults—those 15 years or older—are now overweight, with trends on the rise across different regions of the world and different income levels.
  • Auto industry: Auto industry manufacturing and sales are back in action, with China eclipsing all other contenders and producing more vehicles than Japan and the U.S. combined. Japan, however, had the highest share of hybrid-electric vehicle sales at 11 percent in 2010.
  • Biofuels: Global production of biofuels reached an all-time high of 105 billion liters in 2010, up 17 percent from 2009, mostly as a result of high oil prices, global economic rebound, and new biofuel-related laws and mandates around the world
  • Oil: Global oil consumption reached a new all-time high of 87.4 million barrels per day in 2010. Oil remains the largest commercial source of energy, but its share in the global energy supply has slid for the last 11 consecutive years
  • Ecosystem services: In the U.S., payments for ecosystem services (PES) transactions total $1.5–2.4 billion annually, helping to restore the ecosystems and biological diversity that provide communities with free yet invaluable services
  • Meat: Livestock are responsible for 40 percent of the world’s methane emissions and 65 percent of nitrous oxide emissions. These greenhouse gases are 25 to 100 times more potent than carbon dioxide
  • Factory farming: Factory farming has contributed to a tripling in global meat production over the last four decades. It is associated with heavy use of chemical inputs, the spread of disease, antibiotic overuse and resistance, massive water consumption and declines in human health
  • Population growth: Although fertility rates are falling worldwide, many countries with high birth rates will have to accommodate a rapidly expanding labor force in the next few decades. In Uganda, where women give birth to six children on average, this means needing to generate more than 1.5 million new jobs by the late 2030s.
  • Grain production: Although preliminary data for 2011 indicate that grain production is recovering from a slump, its revival is being seriously hindered by climatic changes and by rising demand for ethanol fuel, producing ripple effects throughout the economy through increased grain prices
  • Nuclear power: Due to increasing costs of production, a slowed demand for electricity, and fresh memories of disaster in Japan, generation of nuclear power fell in 2011
  • Wind Power: Global wind power capacity increased in 2010 to a total of 197,000 megawatts, representing a 24 percent increase from 2009. China is in the lead, overtaking the U.S. in 2010 with 45,000 megawatts of total installed wind power capacity.
  • Natural gas: Driven by surging natural gas consumption in Asia and the U.S., global use of this fossil fuel increased 7.4 percent from 2009 to hit a record 111.9 trillion cubic feet in 2010.

President Donald Trump mocked water-efficiency standards in new constructions last week. Trump said, "People are flushing toilets 10 times, 15 times, as opposed to once. They end up using more water. So, EPA is looking at that very strongly, at my suggestion." Trump asked the Environmental Protection Agency (EPA) for a federal review of those standards since, he claimed with no evidence, that they are making bathrooms unusable and wasting water, as NBC News reported.

A volcano erupts on New Zealand's Whakaari/White Island on Dec. 9, 2019. Michael Schade / Twitter

A powerful volcano on Monday rocked an uninhabited island frequented by tourists about 30 miles off New Zealand's coast. Authorities have confirmed that five people died. They expect that number to rise as some are missing and police officials issued a statement that flights around the islands revealed "no signs of life had been seen at any point,", as The Guardian reported.

"Based on the information we have, we do not believe there are any survivors on the island," the police said in their official statement. "Police is working urgently to confirm the exact number of those who have died, further to the five confirmed deceased already."

The eruption happened on New Zealand's Whakaari/White Island, an islet jutting out of the Bay of Plenty, off the country's North Island. The island is privately owned and is typically visited for day-trips by thousands of tourists every year, according to The New York Times.

At the time of the eruption on Monday, about 50 passengers from the Ovation of Seas were on the island, including more than 30 who were part of a Royal Caribbean cruise trip, according to CNN. Twenty-three people, including the five dead, were evacuated from the island.

The eruption occurred at 2:11 pm local time on Monday, as footage from a crater camera owned and operated by GeoNet, New Zealand's geological hazards agency, shows. The camera also shows dozens of people walking near the rim as white smoke billows just before the eruption, according to Reuters.

Police were unable to reach the island because searing white ash posed imminent danger to rescue workers, said John Tims, New Zealand's deputy police commissioner, as he stood next to Prime Minister Jacinda Ardern in a press conference, as The New York Times reported. Tims said rescue workers would assess the safety of approaching the island on Tuesday morning. "We know the urgency to go back to the island," he told reporters.

"The physical environment is unsafe for us to return to the island," Tims added, as CNN reported. "It's important that we consider the health and safety of rescuers, so we're taking advice from experts going forward."

Authorities have had no communication with anyone on the island. They are frantically working to identify how many people remain and who they are, according to CNN.

Geologists said the eruption is not unexpected and some questioned why the island is open to tourism.

"The volcano has been restless for a few weeks, resulting in the raising of the alert level, so that this eruption is not really a surprise," said Bill McGuire, emeritus professor of geophysical and climate hazards at University College London, as The Guardian reported.

"White Island has been a disaster waiting to happen for many years," said Raymond Cas, emeritus professor at Monash University's school of earth, atmosphere and environment, as The Guardian reported. "Having visited it twice, I have always felt that it was too dangerous to allow the daily tour groups that visit the uninhabited island volcano by boat and helicopter."

The prime minister arrived Monday night in Whakatane, the town closest to the eruption, where day boats visiting the island are docked. Whakatane has a large Maori population.

Ardern met with local council leaders on Monday. She is scheduled to meet with search and rescue teams and will speak to the media at 7 a.m. local time (1 p.m. EST), after drones survey the island, as CNN reported.
