How green is my lawn

Or, what exactly is it we’re trying to do?

I recently moved from a semi-tiny apartment to a house (don’t ask). Included in the package is a relatively small lawn. Despite its smallness, it bothers me for at least two reasons. The first is personal; I grew up in a pretty large and definitely suburban house with a typically large lawn. It was before the days of lawn services, so it fell to my teenage self to mow the acre of really hilly and only sometimes green expanse. That, by the way, is one of the (many) reasons I vowed to never become a dweller in the supposedly idyllic ‘burbs.

I know many will disagree with this aversion, but let me have my rant.

My second distaste for lawns came about as I became increasingly (and I hope not obnoxiously) a proselytizing environmentalist.

In my classes, as I describe the goals of sustainability, starting from the 3Rs through the triple bottom line and beyond, I use lawn mowing and lawns as an example. I first show a picture of a lawn mower and ask the class how, if they were tasked with making it greener, they would go about it. I get the obvious answers regarding fuel efficiency and recycled materials.

But then I push them further and, usually with some prodding, get them to think about lawns themselves rather than lawn mowers. I do this by asking them to take a step back and question what it is we’re really trying to do. A pedagogical goal of  mine is getting my students to question assumptions and thereby arrive at more sustainable solutions. So, the answer, in this case, is that we are trying to create landscapes around our buildings. But, I ask them, are lawns the only or best way to go about this?

Because we take lawns for granted, they often seem to be the only approach. That means it takes a conceptual leap to get past traditional lawns.

So the question becomes not how to make a more environmental lawnmower, but how to landscape more environmentally. Lawns are nice for picnics, Frisbees and dogs (or dogs catching Frisbees while devouring our picnics). But that doesn’t justify surrounding our houses or, even more egregiously, suburban office buildings with innumerable acres of non-indigenous (virtually all lawn grasses are not native to North America), unnecessary and – here’s the big point – resource intensive artificial carpets.

This whole topic came to mind the other day when the blog Earther posted “Lawns Are an Ecological Disaster.” The article provided supporting data for what I’d been saying for years:

  • There are 40 million acres of lawn in the US, nearly half the total acreage of our major crops
  • We collectively spend more money on landscaping – primarily on lawns – than on foreign aid (roughly $50 billion dollars)
  • We use 580 million gallons of gas each year for lawn mowers.
  • We apply 67 million pounds of pesticides – many carcinogenic or untested – to lawns each year.
  • 30% – 60% of municipal drinking water is used for lawn watering

Nor is this new news. Elizabeth Kolbert, among others, wrote about it in depth in the New Yorker back in 2008.

There are yet more issues with lawns, but, hey, this blog is about EcoOptimism. In the class discussion, we eventually get around to the alternative of indigenous planting, though it usually takes, as mentioned above, some prodding. I show them landscapes of wildflowers, xeriscaping and edible lawns.

I also startle them a bit with images of goats, rather than lawnmowers, keeping grass to acceptable height.

This alternative to lawns can take some getting used to. When I recently tried to convince some clients to plant wildflowers in their small urban front yard, they said the pictures I showed them looked like weeds in the Southwest. (They also wanted paving instead of a lawn because it was easier to maintain.)

Many of us think of lawns as being part of nature and therefore something desirable. But unlike forests, lawns are carbon positive. (This is an unfortunate term and unintuitively means that something – grass in this case – emits more carbon into the atmosphere than is removed.) They are also “monocultures.” Forests and other ecosystems are diverse, with their many plants and animals creating self-sufficient, resilient regions. Lawns, on the other hand, can’t exist without being created and maintained – at great natural and financial expense – by humans.

Looked at this way, getting rid of lawns is, as we like to point out here, win-win-win: ecologically, economically and, harking back to my childhood lawn mowing nemesis, a time-saver.

 

The Distillery: February 2, 2018

We can all use some positive news these days, especially on the environmental front in which science is considered evil, denial is an alternative fact and the EPA is now what I’m calling the Environmental Destruction Agency. And while I don’t want to gloss over the issues – there isn’t enough paint in the world to do that – I offer here The Distillery, a weekly (or thereabouts) selection of posts to help offset the PTSD of our current nightmare.

The posts I pick will be “real” in the sense that they aren’t pie-in-the-sky wishful thinking, as fun as those can be, but are evidence of EcoOptimism.


The theme here: good news disguised as bad news

2017’s costly climate change-fueled disasters are the ‘new normal,’ warns major reinsurer

2017 Set a Record for Losses from Natural Disasters. It Could Get Worse

And the “Bomb Cyclone” wasn’t even in 2017, so we’re off to an inauspicious start. But there’s optimism here ….

EcoOptimism’s take: On the face of it, this doesn’t sound like an EcoOptimistic post, but it in fact emphasizes the economic incentive to mitigating and adapting to climate change. Insurance companies – especially reinsurers, the ones who insure the insurance companies – have been concerned with this for a while. The Times article references Munich Re, but Swiss Re has also studied the potential costs of covering insurance losses due to climate change and has been ringing alarm bells.

Arguably, since politicians (American, that is) aren’t onboard, it may be the business world that spurs, finally, US action. Ironically, politicians cling to the belief that environmental action is bad for business.

And if the business case for climate action doesn’t work, maybe the military case can…

Climate Impacts Nearly Half of U.S. Military Bases

EcoOptimism’s take: The US military is a surprisingly staunch advocate for adaptation to climate change. Though Trump ridiculed Obama for saying so, climate change is a national security threat that could both create or exacerbate geopolitical and affect military readiness. This post, though, emphasizes the potential direct cost of climate change. As a military policy, it might even have Trump’s ear and bring him to his senses. But maybe that’s my EcoOptimism speaking.

China is going to stop accepting plastic for recycling, so…

America Needs a Plastics Intervention. Now’s the Time.

EcoOptimism’s take: So China’s going to stop taking the world’s plastic waste for recycling. That problem, though, creates the impetus for better recycling, plastics that are more recyclable, and/or plastics bans here and elsewhere. And, of course, to stop shipping our problems elsewhere.

A new twist to “Read My Lips” and taxes…

Would a Beef Tax Reduce Greenhouse Gas Emissions?

Photo source: Evolution News

EcoOptimism’s take: : Taxes are bad, right? Not if they discourage consumption of things that aren’t good for us or the environment – and meat is both. Think about, for instance, taxes on cigarettes or alcohol. Or sugary drinks, as is catching on in some places. (Though NYC’s proposed tax didn’t survive a lawsuit. On the other hand, the city’s proposal for congestion pricing which, arguably, is a tax, is getting some traction after a false start.)

Now if we can only institute carbon taxes. Or if not that, maybe at least an increase in the decades old gasoline tax, which has been 18.4 cents since 1993. That means it’s actually decreased significantly due to inflation.

But taxes are bad, right?

For the new year, let’s celebrate some renewal – in the form of reforestation. You probably knew that trees are one of the best methods of reducing carbon dioxide in the atmosphere. (Other than not putting it there in the first place.) Though it’s not all good news, here are some posts illustrating just how effective they can be.

EcoOptimism’s take: A Treehugger.com post on the same report put a different spin on it “Restoring nature is climate equivalent of stopping burning oil.


But just to make sure our EcoOptimism is not blind to reality….

“But… Tropical Forests Now Have a Serious Carbon Footprint Problem”

EcoOptimism’s take: All this tells us is that it’s even more important to maintain or, better yet, increase the size of forests and rain forests in particular.

Our end of the year Distillery is newsworthy updates to some recent – and not-so-recent – posts.
And here’s hoping that 2018 will bring us more EcoOptimism. (Because, well, 2017.)

EcoOptimism’s take: Despite first the Obama administration’s efforts and now Trump’s, this groundbreaking lawsuit continues to move forward.

On a related note, a different approach to environmental rights:

EcoOptimism’s take: You’d think that the right to a healthy environment for those who are alive NOW, would be a more straightforward concept than the intergenerational version. According to this post, though, it’s currently a constitutional right in only two states, Pennsylvania and Montana. But it’s being used to challenge pro-industry, anti-environment legislation.

Costa Rica Wants to Become World’s First Country to Eliminate Single-Use Plastics

EcoOptimism’s take: Only a fraction of plastics gets recycled. The rest of this persistent scourge ends up in the oceans and distant beaches or, at best, in landfills to live on virtually forever.

They’ve even been found in the deepest place on Earth: the Marianas Trench.

And in case that’s not nasty enough, bear in mind this doesn’t take into account the resources (oil!) and energy required to make them.

America’s Wind Energy Industry Passed a Major Milestone

EcoOptimism’s take:  in 2016, wind energy passed the generating capacity of hydroelectric power became the nation’s top renewable generating source.

For all the talk naysaying renewable energy – it’s too expensive or too unreliable because “the sun don’t always shine, the wind don’t always blow” – it’s now the most rapidly growing and inexpensive form of energy. More efficient solar cells and new types of batteries will only further the trend, and the renewable energy industry is already creating more jobs than fossil fuels are.
