Straws, Bags and the Other Small Sacrifices That Only Make Us Feel Green

You are standing at the checkout with three oranges and a loaf of bread, and the cashier asks whether you brought your own bag. You did not. So you pay a dime for a paper one, it tears in the parking lot, and a loaf of bread rolls under a minivan. Somewhere in that moment a politician pats himself on the back for saving the oceans.

I want to talk about the small sacrifices: the straw you cannot get, the bag you must pay for, the paper tube that dissolves into a pulp before the milkshake is gone. They are cheap to impose, easy to cheer for and very nearly useless. And they matter, because every hour of public attention spent on a straw is an hour not spent on the things that would actually keep plastic out of the sea.

Defining the Term

Let me define what I mean by symbolic environmentalism. It is a policy chosen because it is visible, easy to explain and morally satisfying, rather than because it measurably improves the environment. It has three marks. It targets something the public can see and hold in its hand. It imposes costs on millions of ordinary people in small, annoying doses. And it produces a benefit so small, or so poorly measured, that its supporters talk about "awareness" instead of results.

Notice that I am not claiming plastic pollution is imaginary. It is real, it is ugly, and it harms wildlife. I am claiming something narrower and more useful: that the policies we have chosen for it are aimed at the wrong target, and that the right target is boring and expensive and unfashionable.

The Case for the Bans, Fairly Stated

The strongest defence goes like this. Single-use plastic is designed to be thrown away, and a thing designed to be thrown away will be thrown away carelessly. Bags blow out of landfills and snag in trees. Straws are small, light and hard to recycle. A ban changes habits at scale, and the habits it changes spill over into other choices. Even if a ban does little by itself, it is a first step that builds support for larger measures. And the sight of a turtle with a straw in its nose has moved more public opinion than a hundred waste-management white papers.

I will give that argument its due. Litter is a genuine nuisance, and a bag in a tree is a real thing. Awareness is not worthless. But a policy has to be judged by what it does, not by what it signals, and when you check the record the bans do not hold up well.

One: The Bag Replacement Problem

A ban on thin plastic bags does not make the need for a bag disappear. People still have to carry groceries, and so they carry them in something else. That something else turns out to have its own environmental footprint, and sometimes a heavier one.

In 2018 the Danish Environmental Protection Agency published a life-cycle assessment of grocery bags, looking at the whole path from raw material to disposal across a range of environmental categories, not just litter. The finding that went around the world was about reuse. To match the overall environmental impact of a standard plastic bag used once and then reused as a bin liner, a paper bag had to be reused dozens of times, a conventional cotton tote thousands of times, and an organic cotton tote on the order of twenty thousand times. Those numbers come from the study's own tables, and I encourage you to read them rather than trust my summary. The reason is not mysterious. A cotton bag takes a great deal of water, land and energy to grow and process, and a thin plastic bag takes very little material to make.

Nobody uses a cotton bag twenty thousand times. Most of us own a closet shelf of them, bought on impulse, given away at conferences or forgotten in the trunk. If the average tote is used a few dozen times and then retired, the ban has replaced a light bag with a heavy one and called it progress.

This does not mean thin plastic bags are good. It means the question "plastic or not plastic" is the wrong question, and a ban that fixes on the material rather than on the full lifecycle can easily make the total outcome worse.

Two: California's 2014 Law and the Trash Bag Surprise

California became the first state to ban single-use plastic grocery bags statewide when Governor Jerry Brown signed Senate Bill 270 in September 2014. Voters upheld it in a 2016 referendum. Stores had to stop handing out thin bags and had to charge at least ten cents for paper or heavier reusable ones.

Here is what ought to interest anyone who cares about results. People do not stop needing bags. Many used those thin grocery bags for a second job, lining the kitchen wastebasket or picking up after the dog. When the free bags vanished, they bought bags to do the job instead. An economist, Rebecca Taylor, studied this and found that sales of small plastic trash bags rose after local bag bans, offsetting a meaningful share of the plastic the ban had removed. Check the paper yourself; I am describing its direction rather than quoting a precise figure. The point is not that bans have no effect. It is that the effect is smaller than advertised, because behaviour adjusts.

I am delighted to report that the market solved the problem the legislature created, in the sense that it invented a new product to fill the gap. I would rather the legislature had asked before it acted.

Three: The Straw and the Sea

Now the straw, which has become the moral emblem of the entire movement. Seattle's ban on plastic straws and utensils at restaurants and bars took effect in 2018, and California followed with a law (signed in September 2018) requiring dine-in restaurants to hand them out only on request. Corporations announced their own phase-outs. Whole sections of the grocery aisle changed.

Let us ask the only question that matters. How much of the plastic in the ocean is straws? The honest answer is that straws are a tiny fraction of the total by weight, and that is why the debate was always more about symbolism than about the sea. I will not give you a percentage, because the estimates in circulation have been disputed and I would rather you look at the underlying sources than at my number. I will give you the direction: it is small.

Meanwhile the substitute has problems of its own. Paper straws go soggy, which is bad for the customer and bad for the cup. Some of the substitutes use materials that are no easier to recycle. And the people for whom a rigid, flexible straw is not a convenience but a necessity, including many disabled people, found that the replacements did not work for them. A policy that quietly makes life harder for the people who needed the old product, in exchange for a gesture, is not a bargain.

Four: Where Ocean Plastic Actually Comes From

If straws and grocery bags in wealthy countries are not the problem, what is?

The best-known estimate came from a 2015 study in the journal Science by Jenna Jambeck and colleagues, who modeled how much plastic waste entered the ocean from coastal countries in 2010. The central finding was that the largest flows came from countries with rapidly growing economies and weak waste-collection systems, where garbage is dumped, burned or washed into rivers because there is no truck to pick it up. The authors identified a limited group of top countries as the largest sources. Later river studies pointed the same way: a limited number of rivers, concentrated in a few regions, carry most of the plastic that flows to the sea. A 2021 study in Science Advances estimated that a thousand rivers account for the bulk of it.

Read the lesson carefully, because it is not about blame. It is about plumbing. The plastic in the sea is overwhelmingly mismanaged waste: waste that was never collected, never landfilled and never burned in a modern plant. The United States has its own litter, and we should clean it up. But a shopper in Ohio who skips a straw is not reaching the place where the plastic enters the sea. The most effective policy is to help build the boring infrastructure that wealthy nations take for granted: collection, sanitary landfills, waste-to-energy plants, and the property rights and local governance that make a system like that work.

Five: What Effective Waste Policy Looks Like

If we wanted results instead of applause, the program would look something like this.

• Collect everything. The foundation is a reliable system that picks up waste before it reaches a river. Where such systems exist, the ocean is not the destination.
• Landfill and burn responsibly. A modern, lined landfill and a modern waste-to-energy plant are tools, not sins. They keep material out of waterways, and the second one makes electricity.
• Pay for the real source. A dollar spent helping a fast-growing river city build collection does more good than a dollar spent lecturing a coffee shop.
• Enforce existing law. Dumping and illegal disposal are already crimes. Enforcing those rules costs less than inventing new categories of nuisance.
• Let innovation work. Recycling technology, better materials and private reuse systems have more room to improve when government does not fix them in statute.
• Measure. Any program should state its target, its cost and its result in numbers, and be repealed if it fails.

None of this fits on a bumper sticker, which is the real objection to it.

The Founding Anchor: Scale, Consent and Cost

There is a constitutional point buried in this, and any student of the Founding would insist on it. The Founders designed a republic in which most matters of everyday life, including how a town handles waste, belong to the states and localities. The Tenth Amendment says that powers "not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people." A bag ordinance is just the sort of thing a city council can pass, and a neighbouring city can decline to pass, and the two can learn from each other. That is the system working. I have no complaint about a town trying a ban and finding out that it does not work.

My complaint is about the national mood that treats every symbolic gesture as a moral test and every skeptic as an enemy of the planet. A free people is entitled to ask what a rule costs and what it buys. When you tell a family that their paper bag is an act of virtue, you owe them the evidence. For a deeper look at how Washington reaches into the household, see Low-Flow Toilets and Banned Bulbs, How Washington Moved Into Your House, and for the broader question of how to weigh climate measures by what they deliver, see Grant the Warming, Then Ask What Each Climate Policy Actually Buys.

The Objection About Small Steps

The most intelligent reply to all of this is: "Fine, but even small steps are steps. You are letting the perfect be the enemy of the good."

I have three answers. First, a small step that distracts from the big one is worse than nothing. Political attention is a limited resource. A legislature that spends a session on straws has not spent it on waste infrastructure. Second, a small step with real costs is not free. Fees fall hardest on people with the least room in the budget, and a family counting grocery dollars notices a dime per bag. Third, a symbol teaches the wrong lesson. It tells the public that the problem is the individual shopper, when the largest contributors are failures of municipal systems half a world away. People who believe they have solved a problem stop looking for the solution.

None of this is hostility to the environment. A conservative who cares about clean rivers and clean beaches should be the first to insist that the policy actually work. The tradition of conservation we admire, from Theodore Roosevelt Made Conservation a Conservative Cause, and It Still Is to the farmers in Farmers Saved the Soil After the Dust Bowl, Long Before Earth Day Existed, was practical, measured and tied to results. It did not need a slogan to make it real. And if you want to see what clean air looks like when the numbers are respected, read The Air Got Cleaner While the Economy Grew, and the Numbers Show How.

What I Would Say to the Cashier

So, back at the checkout. The next time someone asks you to pay a dime for a bag, you can smile and pay it. It is a small thing, and a free society tolerates small things. But you can also ask a question when the ordinance comes up for a vote, and here it is: "What will this reduce, by how much, and how will we know?" If the answer is a gesture, we have learned something. If the answer is a measurement, we have learned something better.

The Case in Brief

1. Symbolic environmentalism favours visible, easy policies over measured results, and bans on straws and bags fit the description.
2. A 2018 Danish life-cycle assessment found that replacement bags, especially cotton, must be reused many times to match a thin plastic bag, which most totes never are.
3. California's 2014 bag law was followed by increased sales of small plastic trash bags, so part of the saving was offset by changed behaviour.
4. Ocean plastic comes mostly from mismanaged waste in a limited number of countries and rivers, not from straws and grocery bags in wealthy cities.
5. Effective policy builds collection and disposal systems, enforces existing law and measures results, and leaves local gestures to local voters.

What you can do: Before your city council or county board votes on a bag, straw or packaging ordinance, email the members and ask for the expected reduction in waste, the cost to residents and the plan for measuring the result.
