First of all Greta is from a first world country so chances are that she and her classmates are already well aware of global warming warming and it’s effects on the planet https://twitter.com/lucasdigrassi/status/1322161059529170945

Secondly, it’s not that developing countries don’t know about global warming, our citizens have to prioritise worrying about putting food on their plates first and keeping themselves alive from day to day

Thirdly, we are not “poor” countries. We are the countries who sit with all the natural resources and as a result are overly exploited countries who pay for the sins of first world countries and their consumerism
