Sona Sharma, Looking After Planet Earth
Looking After Planet Earth by Chitra Soundar.
When Sona learns about the climate crisis at school and is very worried that no one is doing enough to combat it, she takes up the challenge herself. But Appa isn't amused when Sona throws out her baby sister's nappies and Thatha isn't happy when she tells him to get rid of his colour-coded plastic files. When Sona learns that many of the kolams – the traditional art that people draw in front of their homes to celebrate the winter months and the festival season – are not organic, she sets out to make some big changes by getting everyone involved.
