00:57听My research is looking at听if microplastics affect productive soil systems听for my PhD.
01:34听I'm looking at听microplastics, which are plastic particles smaller than 5 mm in size, and they're such a huge problem mainly because of their tiny size.
02:41听It's hard to go for a walk anywhere, even to a park, even down the street, without coming across a piece of plastic. I'm focusing on the ones that we actually can't see.
02:53听The focus on productive soil systems, of course, is because they are really important for us. Microplastics might affect plants, it might affect their growth, or it might affect the community of microorganisms which are so, so important for soil health.
03:39听(Plastic is) ideal for a range of products but that's the problem, it doesn't go away, it just breaks down into smaller and smaller pieces, into these microplastics.
05:13听Our green bins in Christchurch, they don't have those conditions. They're just designed to compost our food scraps. They can't handle plastic.
06:00听I found that听doing a project on microplastics, it was really hard to not do anything about it.
06:24听The more that I learned, I really wanted to share that as well,听I felt responsible for sharing what I learned and helping other people out.
10:24听Once you look at (the sample) through a microscope, generally there's heaps and heaps of plastic, which is kind of sad for the environment, but also kind of exciting for me to say "Oh yay I've managed to get something."
10:42听We kind of joke that听from doing postgrad you end up with a lot of different life skills, and mine鈥檚 probably the ability to be a brain surgeon now from having such a steady hand with trying to pick out tiny, tiny pieces of plastic about 100 micrometres, which is just so small, with tweezers.
12:02 There's no point cleaning up the plastic after it's happened, we might as well turn it off at the source.

Helena Ruffell听is a PhD student in Environmental Science at UC. Her research area is environmental contamination, specifically, the amount of microplastics that can be found in our soils 鈥撎齛nd the effects they might be having. A big believer in walking the talk, Helena is passionate about finding ways to reduce her own plastic waste and inspires others to do the same by sharing her ideas on Instagram.
鈥淚鈥檇 love to see a reduction in the amount of plastic we use daily. There's nothing easy about cleaning up microplastics once they鈥檙e out there. We need to turn them off at the source.鈥
