If these school children are willing to advocate for Planet Earth, good on them, as it seems Planet Earth is poorly represented on the world stage.
For decades we have had well-established, peer reviewed studies and investigations that have documented the ever-increasing pollution of our land, sea and air; deforestation, loss of species, melting of glaciers, ice caps, etc. If I were Mother Nature, I would be very pleased that school children were showing some interest in my health and well-being.
