There are a number of projects helping to protect or clean plastic from our oceans through beach cleans, education, activism, raising awareness or exciting tech. We’ve chosen 5 of our favourite sustainable t-shirts from these projects.
Marine Conservation Society

We should all have the chance to connect with nature and escape from the rush of modern life. The sea is great but it needs to be a clean, safe space, free from pollution, plastic and sewage. Right now, it’s not and that’s not good enough. We need to raise awareness, work together and fight for change. This t-shirt raises funds to continue the fight for a cleaner, safer ocean.
The Marine Conservation Society work to ensure sustainable use of the seas. They do this by minimising harm when harvesting resources, for example through fishing. They also work to prevent and clean up marine litter and pollution. This helps to minimise damage from development and climate change. More than 15,000 of their volunteers clean up our beaches each year, and help to tackle marine litter at source.
They have a great range of fashionable and eco-friendly clothing. Each garment provides a voice for marine conservation in a fresh new way. You can show your support, spread the word and look cool at the same time.
