7 things we’ve learned about Earth since the last Earth Day

Our understanding of Earth — and how we’re changing it — just keeps expanding.

Earth Day turns 48 today, April 22, and Google is celebrating it with a Google Doodle of conservationist Dr. Jane Goodall, who nudges us in a video a “do our part for this beautiful planet.”

When Senator Gaylord Nelson (D-Wisc.) founded Earth Day in 1970, his hope was to make the environment a political issue in an era where US rivers caught on fire and thick smog choked cities.

In many ways, it worked. Since then, major environmental laws have helped clean up much of the vivid toxic detritus in the soil, air, and water in the US. But our challenges today are no less daunting. The accumulation of greenhouse gases in the atmosphere, the loss of wilderness and species, and the acidification and pollution of the oceans have all become more acute — and more destabilizing.

In keeping with the tradition started by former Vox writers Brad Plumer and Joseph Stromberg, here are seven of the most troubling, intriguing, and encouraging things we learned about the Earth since the last Earth Day.

Achieving 100% Renewable Energy is Within Our Reach

“..if you pay a power bill [100% renewable] is increasingly the common-sense path forward.”

We watch in horror as the damages from climate change continue to mount.

Last year, Hurricane Harvey dropped more rain on Houston than any storm has ever dropped on any American city, ever. Hurricane Maria set back development in Puerto Rico 25 years, according to early estimates. And the tab keeps mounting: in 2017 alone, the economic cost of hurricanes and wildfires was greater than the cost of paying tuition for every American in a public college or university. We can’t have a working nation or a world if we don’t stop the climate from careening out of control. That’s been clear for decades now, but what’s been less clear is precisely what we should do about it.

Happily, that’s no longer the case. We now know exactly what to do, and we’re increasingly certain it can be done. We have to switch off of coal, oil, and gas, and on to 100% wind, water, and sun energy sources. And though this drive for a conversion to clean energy started in northern Europe and northern California, it’s a call that’s gaining traction outside the obvious green enclaves. More and more major US cities have taken the pledge to go 100% renewable by the year 2050, while others have taken action to sever their ties with the fossil fuel industry, signifying a global shift in how we’re thinking about our energy system.

Americans waste 150,000 tons of food each day – equal to a pound per person


Research shows people with healthy diets rich in fruit and vegetables are the most wasteful and calls for better education for consumers

https://www.theguardian.com/environment/2018/apr/18/americans-waste-food-fruit-vegetables-study

About 150,000 tons of food is tossed out in US households each day, equivalent to about a third of the daily calories that each American consumes. Fruit and vegetables were the most likely to be thrown out, followed by dairy and then meat.

This waste has an environmental toll, with the volume of discarded food equivalent to the yearly use of 30m acres of land, 780m pounds of pesticide and 4.2tn gallons of irrigated water. Rotting food also clogs up landfills and releases methane, a powerful greenhouse gas.

Researchers at the US Department of Agriculture analysed eight years of food data, up to 2014, to see where food is wasted and also what members of the public say they do at mealtimes. The research has been published in Plos One.

 

Portugal reaches 100% renewables, ends fossil fuel subsidies

Portugal’s renewable energy sources generated enough power to exceed total grid demand across the month of March, a new report has found, setting a standard that is expected to become the norm for the European nation.

According to Portuguese grid operator, REN, renewable energy output over the month reached 4,812GWh, surpassing the nation’s total electricity needs for March, which only topped 4,647GWh.

In that time, power generated by Portugal’s hydroelectric dams accounted for 55 per cent of monthly consumption – boosted by drought-breaking rainfall of four times the monthly average – and wind power, 42 per cent.

The achievement comes nearly one year after hydro, wind, and solar power helped push the Iberian country to run on 100 per cent renewable electricity for 107 hours straight. Last March, however, the average renewables supply was 62 per cent.

Wrapped in a Sea of Plastic

Half a century of this “uncontrolled experiment” is fast becoming as serious a problem as climate change.

Plastics everywhere was bad enough, but now multiple studies have found that 94 percent of our drinking water and 93 percent of sampled bottled water worldwide are full of plastic particles and chemicals, including BPA, heavy metals, phthalates, pesticides, PCBs and other chemicals, many of which are linked in animal studies as well as some human studies to cancer, premature puberty, reduced immunity, birth defects, endocrine disruption, insulin resistance, and other major diseases.  And we have no idea and neither does the FDA, EPA, or any other federal agency, whether this lethal cocktail, which binds together with other toxins, is having an even more profound impact on our health and that of our kids.  What we get now from those agencies is “conflicting findings” and “uncertainties” about the potential impact of plastics-related chemicals. What we do know is that governments only test or analyze the impacts of individual chemicals to determine the levels of potentially life-threatening exposure, making it impossible to figure out the combined total load of chemicals from plastics our babies can safely absorb.

Most plastic waste appears to come from five developing nations in Asia.

Around 8 million tons of plastic waste is dumped in the ocean annually. That equates to emptying a garbage truck of plastic into the sea every minute , most of it single-use products, such as plastic bags, candy wrappers, sachets and soda bottles.

This mismanagement not only pollutes oceans and harms marine wildlife, but also makes life harder for locals, whether they are residents of neighborhoods that regularly flood (owing to drains clogged with plastic), workers at coastal resorts that cater to tourists or fishermen facing dwindling fish stocks. The economic implications are startling. Marine debris cost the 21 Asia-Pacific Economic Cooperation member economies around $1.3 billion in 2008, and that number is only going up as the problem gets worse.

We’re encouraged that the world is waking up to the crisis of plastic waste in our ocean, and working together to resolve it. News outlets around the world highlighted the shocking video earlier this month of the British diver swimming through plastic waste off the coast of Bali. The recent World Ocean Summit, held in Mexico earlier this month, focused extensively on plastic waste. The sixth International Marine Debris conference convened last week in San Diego and highlighted new and emerging science that will help us tackle this growing problem. Earlier this year, Evian, Coca-Cola and other businesses announced efforts to address packaging waste and improve recyclability of their products. 

US Electricity: Natural Gas & Coal Fall, While Renewables Continue to Rise

Electricity generation from both natural gas and coal fell in 2017. At the same time, renewables – especially hydropower, wind, and solar – continued to rise according to new data from the U.S. Energy Information Administration (EIA).

We Are Drowning In Plastic, and Fracking Companies Are Profiting

Plastic production wreaks havoc on people and the planet—from fracking wells and pipelines in Pennsylvania, to air pollution from plastic plants in Scotland.

We are choking the planet in plastic. Everything from wasteful water bottles to grocery shopping bags are polluting our waterways, and endangering marine life and the natural environment. It’s fair to say that even the most casual news consumer has probably encountered a Facebook post, TV report, or radio segment about the garbage patches in the Pacific Ocean.

But what’s less well-known is what is fueling this plastics binge: fracking. As the Guardian recently reported, in less than a decade, tens of billions of dollars have been invested in creating new manufacturing sites around the world to turn fossil fuels into resin pellets used to manufacture plastic products. The companies profiting off this surge in plastics are contributing to a growing climate crisis while generating mountains of plastic garbage.

CLIFFE, KENT – JANUARY 02: Plastics and other detritus line the shore of the Thames Estuary on January 2, 2018 in Cliffe, Kent. Tons of plastic and other waste lines areas along the Thames Estuary shoreline, an important feeding ground for wading birds and other marine wildlife. According to the United Nations Environment Programme (UNEP), at current rates of pollution, there will likely be more plastic in the sea than fish by 2050. In December 2017 Britain joined the other 193 UN countries and signed up to a resolution to help eliminate marine litter and microplastics in the sea. It is estimated that about eight million metric tons of plastic find their way into the world’s oceans every year. Once in the Ocean plastic can take hundreds of years to degrade, all the while breaking down into smaller and smaller ‘microplastics,’ which can be consumed by marine animals, and find their way into the human food chain.

What Does China’s ‘Ecological Civilization’ Mean for Humanity’s Future?

Imagine a newly elected president of the United States calling in his inaugural speech for an “ecological civilization” that ensures “harmony between human and nature.” Now imagine he goes on to declare that “we, as human beings, must respect nature, follow its ways, and protect it” and that his administration will “encourage simple, moderate, green, and low-carbon ways of life, and oppose extravagance and excessive consumption.” Dream on, you might say. Even in the more progressive Western European nations, it’s hard to find a political leader who would make such a stand.

And yet, the leader of the world’s second largest economy, Xi Jinping of China, made these statements and more in his address to the National Congress of the Communist Party in Beijing last October. He went on to specify in more detail his plans to “step up efforts to establish a legal and policy framework … that facilitates green, low-carbon, and circular development,” to “promote afforestation,” “strengthen wetland conservation and restoration” and “take tough steps to stop and punish all activities that damage the environment.” Closing his theme with a flourish, he proclaimed that “what we are doing today” is “to build an ecological civilization that will benefit generations to come.” Transcending parochial boundaries, he declared that his Party’s abiding mission was to “make new and greater contributions to mankind … for both the well-being of the Chinese people and human progress.”
