David Suzuki: Food Waste Is a Crime Against the Planet
Thanksgiving is a time to gather with friends and family to appreciate the bounty of the fall harvest. Eating is both a highly social and personal part of our lives and food preferences can even make for lively dinner table conversations.
In North America we tend to focus on how food is grown and harvested. Consumers face a myriad of labels when they shop for Thanksgiving feasts—organic, free range, cage-free, Marine Stewardship Council, fair trade, non-GMO, vegetarian-fed and locally grown among them. From a sustainability point of view, though, the most important question is missing from these labels: Will this food be eaten or will it end up contributing to the world's growing food-waste problem?
We're hearing a lot about food waste lately. Every year a staggering one-third—1.3 billion tons—of the world's food is wasted after it has been harvested: 45 percent of fruit and vegetables, 35 percent of fish and seafood, 30 percent of cereals, 20 percent of dairy products and 20 percent of meat. Food waste ends up in landfills, increasing methane emissions and contributing significantly to climate change. A recent study found Americans waste close to $200 billion on uneaten food while Canadians throw away $31 billion.

These figures only account for 29 percent of the full cost of waste. They don't include factors such as labor, fuel to transport goods to global markets, inefficiency losses from feed choices used to produce meat and fish or food left unharvested. As methodologies are improved and accounting becomes more inclusive, we're likely to find even higher waste figures. Dozens of studies across many countries with different methodologies not only confirm the increase in food waste but suggest food waste is even higher and on the rise. In Canada, food waste cost estimates increased from $27 billion to $31 billion between 2010 and 2014.
In a world where one in nine people doesn't get enough to eat—many of them children—this is unconscionable. According to the World Food Program, poor nutrition kills 3.1 million children under the age of five every year. It's the cause of almost half of child deaths in that age range. When it comes to feeding the world, distribution and waste appear to be greater problems than population. And yet we continue to destroy more forests, drain more wetlands and deplete the oceans of fish to meet the needs of a growing world population.
Not only that, the monumental economic losses from food waste represent money that could be used to fund much-needed social and environmental programs. Money lost in North America would cover most of Canada's federal budget. Food waste in Metro Vancouver homes adds about $700 a year to a household's grocery bill.
Every morsel of food wasted represents unnecessary greenhouse gas emissions, conversion of natural ecosystems to agricultural lands and disruptions to marine food webs. Based on 2007 data, the UN estimates that the equivalent of 3.3 gigatons of CO2 emissions globally can be attributed to food waste. Canada's total emissions, in comparison, are about 0.7 gigatons. If food waste were a nation, it would be the world's third-largest emitter.
We need to tackle food waste at all levels, from international campaigns to individual consumption habits. In September, the UN agreed to an ambitious global goal of reducing food waste by 50 percent by 2030 as both an environmental and humanitarian imperative. Earlier this year, Metro Vancouver joined the international effort Love Food Hate Waste to meet municipal waste goals and encourage individual behavioral change. A similar UK campaign led to a 21 percent cut in food waste over five years. Grocery stores in France and other countries are offering discounts for misshapen produce under an “ugly fruits and vegetables" campaign. Businesses are using audits to map out where food waste is affecting bottom lines.
Food waste is a crime against the planet and the life it supports. Reducing it not only addresses food insecurity, it benefits everyone. This Thanksgiving dinner, whether you're vegan, vegetarian, carnivore, locavore or pescetarian, plan for a zero-food-waste meal. Show thanks for ecosystems, growers and harvesters by buying only what you will eat and eating all that you buy.

More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
