What you can do to reduce marine pollution

There’s plenty you can do, either on your own or in a group, to make a huge difference:

  1. Organise a beach clean-up.
  2. Reduce your rubbish.
  3. Make sure only rain goes down the drain. Most drains flow straight to the sea … which means we could end up swimming in anything that goes down them!
  4. Take care of a local stream.
  5. Find out more about your local beach.

For lots of other great ideas on how to take care of your beach and coastline check out the following websites:

1. “Organise a beach clean-up”

Wouldn’t it be great if we never saw any rubbish on our beaches? Unfortunately, this isn’t always the case. Picking up other people’s rubbish, if it is safe, is an easy way to help reduce pollution on our beaches and in the of the ocean. Some people pick up beach rubbish in groups – this is called a beach clean-up. Beach clean-ups are doing great things to reduce marine pollution. If you would like to join a beach clean-up group first contact your council to see if any groups already exist.

If there aren’t any groups in your area, you could start your own!

To find out how to organise one check out the Sir Peter Blake Trust's Clean Up Our Coasts webpage where you can download the Clean up your Coasts kit and find summaries of past beach clean-ups.

Collecting information on the rubbish that you find on the beach is also really important. The Sir Peter Blake Trust beach clean-up kit helps you to collect this information. Once you’ve collected the information, send your results into the Sir Peter Blake Trust. They will receive results from lots of beach clean-ups. This information will tell us about the kinds of rubbish being collected and maybe where it is coming from. This can be really helpful in finding ways to reduce rubbish at the source.

Don’t forget to check out our competition where we can help get you and your classmates to a beach for a clean up.

2. Reduce your Rubbish

"Sometimes rubbish looks like food
to me, but it tastes yuck and
it’s really bad for me. Some
rubbish is hard to see and
I can swim into it and get tangled."

Studies have shown that about 70 percent of marine pollution comes from the land. So, one of the main ways to reduce marine pollution is to get rid of rubbish carefully, wherever we are. If we reduce the amount of rubbish we make on the land it is likely there will be less rubbish in the ocean.

As well as good tips for reducing rubbish, this website has some amazing facts about waste in New Zealand. It also has some links to projects in your region that help reduce rubbish.

Some organisations are working hard to reduce rubbish too. The Ministry for the Environment is working with New Zealand businesses to find ways to lessen packaging of their products. Some organisations are using science and technology to discover ways to use recycled items in their products. And more and more organisations are reducing their rubbish by recycling their waste.

3. “Make sure only rain goes down the stormwater drain!” Most drains flow straight to the sea … which means we could end up swimming in anything that goes down them!

my pipi lunch. Hope it’s cleaner
up the coast!"

One way rubbish from the land makes it into our oceans is through stormwater drains. These drains collect and remove the rainwater from our streets. Unfortunately anything collected by the rainwater as it travels across the road and down the gutters – like cigarette butts, oil from cars and other bits of rubbish – also goes into the stormwater drains. The drains then transport this mix of rainwater and rubbish to our streams and rivers. These streams and rivers flow out to our oceans and this is where the rubbish can end up.

Fortunately there are lots of things we can do to make sure rubbish is not washed down stormwater drains. Important actions are to dispose of your rubbish carefully and reduce your rubbish. If there is less rubbish on the street there is less chance it will be washed down the stormwater drains. Check out the Reduce your Rubbish section above to learn more.

Children in Auckland Schools decorationed a drain. Another great idea is to not wash your cars on the road or on driveways, as the suds and waste from the car washing flow straight to the stormwater drain. Wash the car on the lawn or take it to a commercial car wash that collects and treats the car wash water.

A fun way to get the message out about stormwater drains is to do some drain decoration. Drain decoration is where a picture or a sign is placed near a drain to remind people that what goes down the drain goes into streams and then into the ocean. You need to ask your council whether you can do this first.

4. “Take care of a local stream”

"All this sediment can clog up us

for us to breathe and eat.
It also shades the plants over
there from the sun, which they
need to survive."

As most streams and rivers flow into the ocean, taking care of them can help reduce marine pollution. If rubbish ends up in a stream or river it will very likely end up in the ocean. Another type of marine pollution that comes from streams and rivers is soil or sediment pollution. Sediment pollution can happen when soil enters waterways that flow to the sea. It is natural for some sediment to enter the ocean, but when there is a lot of it entering the ocean it becomes a problem. Sediment pollution can be increased by human activities such as earthworks near streams or when plants near streams have been removed.

Taking care of streams and rivers can include picking up rubbish, if it is safe, and/or planting trees near the stream – which is called riparian planting. Plants on the banks of streams help to hold stream and river beds together, making them stronger, and stopping soil from being washed away (eroded).

Getting together with a group to take care of a stream is fun. Your council may help groups taking care of streams by giving you some plants, helping you understand how to take care of a stream and even showing you how to test the stream’s health. To find out if there are any groups taking care of streams and rivers in your area, just contact your council. If there aren’t any groups in your area, you can ask the council to help you set one up!

5. Find out more about your local beach. Get your friends and family involved in helping out.

Picture of te coastline. Your local beach is a great place to start learning about the marine environment. You can see many living things at the beach – not just humans! Your local beach is also a great place for you to make a difference. You can make a difference by picking up rubbish and making sure you take your rubbish home with you.

 

Humans can be affected by marine pollution. Marine pollution can make us sick if we swim at or eat seafood from a beach with certain types of marine pollution. Our regional councils monitor the popular swimming spots in summer and let us know whether it is safe to swim there or not. They also monitor popular shellfish gathering sites and let us know if it’s safe to eat shellfish from these areas. To check out the condition of your local beach you can visit your regional council’s website – almost all the regional council’s websites have up to date information on the popular swimming spots. Use this link to select your regional council’s website.

Ask your family and friends to get involved in reducing marine pollution! You can work together to:

  1. Organise a beach clean-up
  2. Reduce your rubbish
  3. Make sure only rain goes down the drain
  4. Take care of a local stream.
