I must admit that when it comes to science, I am a bit thick. As thick as two short planks as we say here in Yorkshire. I am to science what Atilla the Hun was to embroidery. Frigging useless.
Therefore would you please forgive me as I pose this conundrum. It is something that has been in the back of my mind for a long while.
Okay, here we go.
On this planet we have trees and fields. Every year the trees bear masses of leaves, fruit, nuts and seeds. The fields sprout corn, potatoes, turnips, rice and plenty of other stuff.. That's a lot of volume wouldn't you agree? If these products of the earth were all piled up together we could make massive mountains every year.. Then the next year there'd be more mountains till the planet would be covered with such piles.
Effectively, the planet would be growing - expanding every year - as long as we didn't eat the stuff or burn it. And we would have to protect it from natural rotting processes.
The wheat and the apples and the courgettes (American: zucchini) grow where once there was nothing - creating an extra volume of matter.
It's all very puzzling. I just don't get it... but as I say with regard to science I am a dunce in a pointy hat.
P.S. I hope the trees and the fields continue to produce in the bountiful manner described because climate change has already begun to curtail this timeless process.
