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.

 

Plastics: A Combined Distillery and EcoOptimism post

I’ve been meaning to do a Distillery post on plastics for a while but, like plastics, the news has been accumulating faster than I can keep up with….

They barely existed until Leo Baekeland invented Bakelite in 1907. In the 60s, they were the future, at least according to the advice Dustin Hoffman was given in The Graduate. Now, of course they’re everywhere. Literally. This thoroughly unnatural human-made detritus has been found in the deepest trench in the ocean.

Plastics are no longer the future. But they’re definitely the past in the sense that all the petroleum-based plastic ever made is still here. And will be for a very long time since they break down excruciatingly slowly.

What’s so insidious about plastic is that it’s in virtually everything. So much so that we don’t even notice it anymore. And it’s perhaps the egregious example of take, make and waste, especially since we tend to use plastic – which essentially lasts forever – for things have only a fleeting life of usage. Consider take out containers. The food goes in and gets consumed, often in a matter of minutes, but then the plastic container may end up in a landfill for hundreds of years or more. Or it may end up in ocean garbage patches of unfathomable size, killing fish and animals that mistake it for food.

The newest topic in plastics is straws. They weren’t on anyone’s radar until now. Among all the other things around us made of plastic, they seem insignificant. But it turns out they aren’t and it just takes some simple visualization to get it.

We could say something like “if you put every straw end on end it would circle the Earth a million times.”  Never mind the actual number; it’s too abstract. Like the national debt, it’s so big that we can’t grasp it. It’s unrelatable. But make it something we can see, and everything changes.

But the Distillery and this blog are about positive “EcoOptimistic” news and topics. And on the topic of plastics, amidst all the bad news – indeed because of it, which qualifies it as “good news disguised as bad news” – there’s been a strong, almost startling, movement by governments and companies to address this scourge. In Facebook terms, it’s trending. So let’s look at the extent of this overdue but amazing trend.

As evidenced by these posts, the UK seems to be a leader in the movement to eliminate plastics. The “Together We Can” pact involves governments, businesses, local authorities, NGOs and citizens and is described as “is the only way to truly transform the UK’s plastics system.”

Amidst this, companies other than supermarkets are getting the message, too. McDonalds is trialing eliminating plastic straws in the UK. There have been many reports about this, but as perhaps a sign of its wide support, here’s one from – get this – Fox News.

“McDonald’s working to remove plastic straws from UK restaurants”

McDonalds in the UK, however, is more enlightened than the mother ship here in the US, where the board of directors is fighting a stockholder initiative to get rid of plastic straws.

And then there’s the issue of plastic bags. They, too, have a fleeting useful life, usually less than an hour (unless you reuse them – and the dog-poop excuse doesn’t count). One stat says “Worldwide, a trillion single-use plastic bags are used each year, nearly 2 million each minute.”

Plastic bag bans have been instituted in various locations around the world, but of course the US is lagging behind. And also, of course, California led the charge last year by becoming the first state to ban them. An effort to curtail usage in NYC by charging five-cents per bag failed last year, but almost exactly a year later, Governor Cuomo is proposing an outright ban rather than a fee. Washington, DC’s five-cent charge imposed in 2010, it should be noted, is credited with reducing usage by 87%.

And the most comprehensive approach yet is from a tiny island it the South Pacific, known for its beaches and coral reefs – now being marred by plastic debris.
