When a plant is under attack it releases a gas which warns neighbouring plants to protect themselves.

Interesting. But I would like to know exactly how the other plants protect themselves cos they always seem to get attacked too. You just have to look at something like the colarado beetle on tatties, or the cabbage white caterpillar on cabbages. Greenfly on roses etc.  Their defence mechanism doesn't work very well

That is pretty interesting to watch.  So, the plant releases a toxic gas, and it looks as though the other plants start releasing the same gas. Who/what it's toxic too isn't mentioned though.  I wonder if this happens with all plants, or just certain kinds.

I don't feel we have ever touched the surface of our natural world and mother earth. Thanks for this. It just confirms my personal understanding of " Mother Earth".
