The two t-shirts have been made using recycled plastic waste which Holland hopes will help bring attention to the 7.7 billion single-use water bottles that end up in seas and landfill every year. “By wearing these t-shirts, we want people to make a pledge to stop using single-use plastic water bottles all together, and remind people that reusable is the more conscious option,” said Holland, who has become famous for his ‘cheeky’ slogan t-shirts. An average of seven waste plastic bottles were turned into yarn and mixed with salvaged organic cotton to create each slogan t-shirt. According to BRITA,who have launched the shirts as part of its #SwapForGood campaign, 5.5 billion plastic bottles were not collected to be recycled by UK households in 2016. BRITA hope the campaign will help in its mission to persuade people to switch from using single-use plastics to reusable alternatives such as its fill&go filter bottle. Rebecca Widdowson, director of marketing at BRITA UK said: “#SwapForGood campaign encourages people to make small changes to their lifestyle that can have a big impact on the environment. We will be offering BRITA fill&go bottles to purchase alongside these slogan t-shirts at a discounted rate so you can make the swap for less.” The initiative has been backed by actress and environmentalist, Lily Cole, who said that ‘since finding out that there will be more plastic in the ocean than fish in 2050’, she knew it was time to take action. “We have a responsibility be more conscious about our choices; by choosing a reusable bottle we can reduce the amount of needless waste plastic that ends up in our oceans and landfills,” said Cole. The t-shirts are on sale on the House of Holland website with the profits going to the Marine Conservation Society.
