David Suzuki: Demanding Economic Growth on a Finite Planet Robs Future Generations
Aug. 2 was Earth Overshoot Day. Unlike Earth Day or Canada Day, it's not a time to celebrate. As the Earth Overshoot Day website explains, it marks the time when "we will have used more from nature than our planet can renew in the whole year." That is the definition of unsustainable and means we're using up the biological capital that should be our children's legacy. We would require 1.7 Earths to meet our current annual demands sustainably.
It doesn't have to be this way. "Our planet is finite, but human possibilities are not. Living within the means of one planet is technologically possible, financially beneficial, and our only chance for a prosperous future," said Mathis Wackernagel, CEO of the Global Footprint Network, an international research organization that uses UN statistics and other sources to calculate when overshoot day falls every year. This year marks the earliest overshoot date yet.
(Wackernagel was a student of University of British Columbia ecologist William Rees. They popularized the footprint concept in their 1996 book, Our Ecological Footprint. Andrew Simms of the U.K.'s New Economics Foundation conceived Earth Overshoot Day, partnering with the Global Footprint Network in 2006 on the first campaign, and with conservation organization World Wildlife Fund starting in 2007).
According to the website, overfishing, overharvesting forests and emitting more carbon dioxide into the atmosphere than natural sinks like forests can sequester are among the ways we overshoot Earth's capacity. The consequences are serious. "Impacts of ecological overspending are apparent already in soil erosion, desertification, reduced cropland productivity, overgrazing, deforestation, rapid species extinction, fisheries collapse and increased carbon concentration in the atmosphere," it notes. "Natural capital constraints also pose a threat to economic performance and economic stability."
Climate change is the most serious result. The Global Footprint Network says our carbon footprint makes up 60 percent of our total ecological footprint, and it's increasing rapidly. Basing its calculations on "the land area required to sequester carbon dioxide emissions from fossil fuel burning and cement production," the network says our carbon footprint has more than doubled since 1970.
The network also offers a mobile-friendly personal footprint calculator. Be warned: If you live in North America, your footprint will likely be much higher than 1.7 Earths, no matter how ecologically aware you consider yourself. We use far more energy and other resources than people in many parts of the world.
The site includes a range of solutions in four areas: food, cities, population and energy. In North America, reducing the carbon footprint by using less energy—especially fossil fuels—is major, but so is changing food habits. Food demand makes up 26 percent of the global footprint. Because raising animals for food requires far more resources and creates more emissions than growing plants, reducing the amount of meat and animal products we eat decreases our footprint. According to Oregon State University researchers, if Americans ate beans instead of beef, the U.S. could meet its 2020 greenhouse gas emissions goals, even if the country did little else and if people continued to eat other animal products.
Food waste is another major problem. One-third of the food produced worldwide is wasted or lost—as much as 40 percent in the U.S.
Population is an obvious concern. More people require more space and resources. Strategies to stabilize population growth also have social benefits. "Educating girls and providing access to safe, affordable and effective family planning" and "empowering women" are essential to reducing population growth and result in better economic development and health outcomes.
Because humans are increasingly urban dwellers—with 70 to 80 percent expected to live in cities by 2050—things like "energy-efficient buildings, integrated zoning, compact cities and effective options for people-powered and public transportation" are crucial to reducing our footprint.
Some have criticized the Earth overshoot concept, arguing it's not accurate or that it underestimates resource overuse. Wackernagel admits the calculations are only as good as the available data, but argues that it remains a useful way to put our unsustainable ways in perspective.
Demanding constant economic growth on a finite planet with limited ability to renew resources is a recipe for overshoot. We can and must do more to reduce our growing impact on the only home we have.

‘Companies Should Not Be Allowed to Use Hazardous Ingredients in Products People Use’: Michelle Pfeiffer Speaks Up for Safer Cosmetics
The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.
Michelle Pfeiffer wants to change that.
The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

Scientists at the United Nations' intergovernmental body focusing on biodiversity sounded alarms earlier this month with its report on the looming potential extinction of one million species — but few heard their calls, according to a German newspaper report.
The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.
Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.
President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.
"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
"There was a lot of devastation throughout the state," Governor Mike Parson said at a Thursday morning press conference, as NPR reported. "We were very fortunate last night that we didn't have more injuries than what we had, and we didn't have more fatalities across the state. But three is too many."
