How Your Morning Routine Affects Wetlands

Let’s trace a typical morning in your home and follow where everything goes.

You wake up and shower with body wash containing microplastics. Those tiny particles travel down the drain, through the sewage system, and – despite water treatment – many end up in waterways and wetlands.

You wash your face with an exfoliating scrub. More microplastics are on their journey to aquatic ecosystems.

You take your daily medication with breakfast. Years from now, when these medications expire, there’s a good chance they’ll be flushed down the toilet, sending pharmaceuticals directly into wetlands where they’ll disrupt fish reproduction and harm aquatic life.

You wash your car on the driveway before work or on the weekend. Soap, oil, grease, and grime flow into the storm drain and – untreated – straight into local waterways and wetlands. The phosphates in your car wash detergent will trigger algae blooms that suffocate fish.

You toss a coffee cup out your car window on the way to work. (Okay, hopefully you don’t, but someone does.) That cup washes into a gutter, travels through the stormwater system, and ends up in a wetland where it’ll persist for decades.

Welcome to the hidden journey of pollution.

This World Wetlands Day, let’s pull back the curtain on how our daily routines – seemingly disconnected from nature – directly impact wetland health.

The driveway connection

One of the most significant – and surprising – sources of wetland pollution is car washing at home.

When you wash your car on your driveway or street, you’re essentially creating a direct pipeline to the nearest wetland. The runoff – containing soap, oil, grease, road grime, and brake dust – flows into storm drains. And unlike sewage systems, storm drains don’t go to treatment plants. They flow directly into creeks, rivers, and wetlands.

Phosphates in many car wash detergents are particularly problematic. They act as fertiliser for algae, triggering explosive growth known as algal blooms. As these blooms decompose, they consume oxygen in the water, creating “dead zones” where fish and other aquatic life suffocate. It’s called eutrophication, and it’s one of the major threats to wetland health across Australia.

The solution? Take your car to a commercial car wash. They’re required by law to send wastewater to treatment plants or filter and reuse it on-site. They also use significantly less water – 150-230 litres compared to up to 380 litres for home washing.

If you must wash at home, do it on your lawn or gravel area where the ground acts as a natural filter, and always use phosphate-free, biodegradable products.

The bathroom cabinet problem

Your bathroom cabinet probably contains several products that, when washed down the drain, harm wetland ecosystems.

Sunscreen chemicals like oxybenzone and octinoxate wash off your skin in the shower and during swimming. These chemicals eventually reach wetlands and coastal areas where they damage aquatic life, disrupt reproduction in fish, and harm coral reefs.

Microplastics in face scrubs, body washes, and toothpastes are too small to be filtered by water treatment plants. They accumulate in waterways and wetlands, where they’re consumed by fish, frogs, and water birds, entering the food chain and concentrating as they move up.

Pharmaceuticals pose an emerging threat to Australian wetlands. When old medications are flushed down toilets, they bypass treatment systems and enter waterways. These drugs affect fish reproduction, alter behaviour in aquatic animals, and disrupt entire ecosystems.

The good news? There are simple swaps. Choose mineral-based sunscreens with zinc oxide or titanium dioxide. Avoid products containing microbeads. Take expired medications to your pharmacy’s free Return Unwanted Medicines (RUM) program.

The footpath that leads to wetlands

Here’s something most people never consider: that piece of rubbish on the footpath outside your house is on a journey to a wetland.

When rain comes, street litter washes into gutters. From gutters, it enters storm drains. Storm drains flow into creeks and rivers. And eventually, that plastic bottle, food wrapper, or cigarette butt ends up in a wetland.

In 2023-24, Australians consumed 4.0 million tonnes of plastic. We have the highest consumption of single-use plastic per capita globally at 60 kilograms per person annually. Approximately 87% of plastics go directly to landfill after use, but much of the rest ends up as litter that travels to wetlands.

Once in wetlands, this rubbish:

• Is mistaken for food by wildlife, leading to injury and death
• Breaks down into microplastics that contaminate the entire food web
• Destroys habitat and alters water flow
• Leaches chemicals into the water

The solution is simpler than you think: keep gloves and a bag in your car or backpack. Pick up rubbish when you’re walking the dog, commuting, or heading to the shops. Even collecting a few pieces intercepts pollution before it reaches wetlands.

The bin that determines wetland health

What you put in your bins matters for wetlands too.

NSW households’ red-lid bins contain around one-third food waste that could be composted instead. When food waste goes to a landfill, it produces methane – a potent greenhouse gas contributing to climate change. Climate change directly threatens wetlands through altered rainfall patterns, intensified droughts, and rising sea levels.

By composting food waste – or signing up for your council’s FOGO (Food Organics Garden Organics) service – you’re not just reducing methane emissions. You’re protecting wetlands from climate impacts.

Why these connections matter

The hidden journey of pollution reveals an important truth: we don’t have to live near a wetland to impact it.

In fact, some of the most significant threats to wetland health come from ordinary homes in ordinary suburbs, where people have no idea their daily routines affect ecosystems kilometres away.

But here’s the empowering flip side: if our daily choices can harm wetlands, they can also protect them.

Small changes – washing your car differently, switching sunscreens, picking up rubbish, composting food waste – close the pathways through which pollution reaches wetlands.

Individually, these actions might seem insignificant. But when thousands of people make these changes, the collective impact is substantial. Thousands fewer litres of contaminated water entering storm drains. Tonnes of rubbish are intercepted before reaching waterways. Significant reductions in chemical and nutrient pollution.

Take the 7-day challenge

This World Wetlands Day, Conservation Volunteers Australia invites you to understand and act on these hidden connections through our 7 Days to Protect Australian Wetlands Challenge.

Each day of the challenge addresses a different pollution pathwayfrom your driveway to your bathroom cabinet, from your footpath to your bins. You’ll learn not just what to do, but why it matters and how it connects to wetland health.

These aren’t complicated environmental actions requiring special equipment or major lifestyle changes. They’re simple swaps and small habit changes that anyone can make, anywhere in Australia.

Download the free guide and discover how your morning routine can become part of the solution rather than part of the problem.

Because every wetland-friendly choice you make closes a pathway for pollution – and opens a pathway for hope.
