I'm Neil. And I'm Sam. Now tell me about your teeth cleaning routine. OK, well it's pretty good. I think I brush twice a day and change my brush every couple of months. And what kind of brush do you use? Nothing fancy奇特的, just a regular cheap plastic one. Oh dear亲爱的人. What do you mean? Well, imagine all the toothbrushes you've used in your life from your first brush as a child to the one you currently当前 have. You do realise that probably they all still exist in the environment somewhere.
We used them for a couple of months, yet they will last for hundreds of years. Oh dear亲爱的人. And I thought I was actually实际上 quite environmentally在环境方面地 aware知道的. But that's quite shocking. I hadn't thought of that. Well, it's just one of the problems we're facing with our use of plastics. A marvellous invention that has given us so much. But we are beginning to realise it's causing many long lasting environmental环境的 problems.
