About Us

Us & the boycott

We are Kate and Ami blogging as Polythene Pam and Village Boy. We live up north in West Yorkshire, U.K. in a small industrial town. We don’t have pets or kids.
We often shop at supermarkets (but don’t like them), eat meat, drink alcohol, munch cheese and scoff down cake. Giving up is not in our nature – we want to do everything – just without creating a huge pile of non-biodegradable, possibly carcinogenic, lethal rubbish that future generations will have to clean up. more on us, and why we don’t like plastic, here…
