The La Martiniere Girls' College in Lucknow established the PALS Nature Club in 1996. PALS aims to promote environmental protection and recycling. They identified polythene as a major threat, especially to animals in the Lucknow Zoo who were dying after ingesting plastic. To address this, PALS began making paper bags from recycled newspaper and calendars to replace polythene bags for snacks sold at the zoo, in order to protect the animals. The zoo officials accepted their help and the paper bags are now used by all vendors on zoo premises.
