All is not lost, however. We still have a chance to reverse ocean pollution and improve the future for all life on the planet. Here’s all you need to know about the world’s oceans, and the steps you can take to improve their health.
What is World Oceans Day?
World Oceans Day has been marked every year since 1992 as a way to celebrate the world’s seas and the vital role it plays in the vitality of all life on Earth.
Oceans don’t just provide a vital source of oxygen to the world – they’re also a key resource for food and medicines to humans around the world.
In addition to this, oceans are able to absorb vast amounts of CO2, mitigating some of the warming effect created by the release of greenhouse gases.
Each year, World Oceans Day has a different theme to highlight one important aspect of the world’s seas.
Human activity has created numerous threats to the vitality of oceans.
Ocean pollution is one of the most pressing threats created by humans, and comes from a variety of sources.
Many pesticides and nutrients used in agriculture end up in the sea, starving the water of oxygen and killing the lifeforms that depend on it.
Oil spills, plastics, and sewage are other key sources of ocean pollution, and all present threats to biodiversity in water bodies across the globe.
Without action on plastic pollution in particular, it’s estimated that by 2050 there could be more plastic in the oceans than fish populations.
Overfishing has also severely depleted fish stocks and upset the balance of ocean ecosystems. According to the UN, around 90 per cent of big fish populations have been destroyed as a result of human activities.
Particular fishing methods such as bottom trawling can also have devastating impacts on other marine life as well as disturbing the ocean floor and releasing CO2 locked into it.
Luckily, acting on ocean pollution starts with you – and there are plenty of easy ways you can help.
The easiest way to act on ocean pollution is to start being more conscious about your own plastic consumption, avoiding buying or using single use plastic items wherever possible.
If you must use plastic, try to think of new ways to use the item at home afterwards before throwing it away or recycling it.
Old yoghurt pots could become plant pots, for instance, or you could use old plastic bottles to make bird feeders.
If this isn’t possible, always try to recycle your plastic items rather than throwing them away. You should check with your local authority what you’re permitted to recycle at home and what you might have to take elsewhere to recycle.
Reducing pollutants in the cleaning or gardening products you use can also help reduce ocean pollution. Choosing non-toxic, non-chemical products will help avoid harmful chemicals entering the oceans in runoff.
Avoiding fish in your diet – or ensuring fish you do buy is sustainably sourced – is another way to avoid contributing to ocean plastic and overfishing in the world’s seas.
Beyond individual actions, you can also push for change on a wider scale. A number of businesses across the UK are signed up to the “Plastics Pact”, which is a voluntary target to eliminate single-use plastic and ensure all packaging is reusable or recyclable.
If your local supermarket or shop isn’t signed up to this, you could consider writing to them or campaigning to encourage them to take part.
Speaking with or writing to your MP to ask them to lobby the government is another way to push for change on a wider scale. The free “write to them” service offers an easy way to do this online. The government is consulting on environmental targets, including targets on plastic pollution, until the end of June. They’re asking for people’s views on these targets and you can give yours at this link.
And, here are some more top tips from Raffi Schieir, director of the Prevented Ocean Plastic programme:
Rethink your food shop
Wasted food means all the energy, fuel and water that went into its production is lost and, as it decomposes in landfill, it also emits greenhouse gases which have a significant impact on climate change, causing heat to be trapped in our atmosphere. This means the oceans are absorbing more heat, causing an increase in sea surface temperatures and rising sea level.
You can limit food waste at home by planning meals in advance. Where possible, choose loose fruit and vegetables to avoid having spare items that you don’t need and won’t use. Factoring in some meat-free days is another great way to reduce your carbon footprint.
Keep our beaches clean
We urgently need to stop plastic pollution reaching our oceans and we can all play a part. Those lucky enough to live by the sea can take part in beach cleans, picking up litter before it can get into the waterways. You can head out on your own with a bin bag and spend half an hour litter picking, or why not take part in an organised group beach clean with a group like Surfers Against Sewage?
Whenever we visit the seaside, we can all play our part by making sure to take all our rubbish away with us and recycling it
