I recently re-read Wastelands and got inspired to write a new riddle...
I will donate $10 to the HF if someone solves it in less than 7 days from now!
I came from the sea,
Although my predecessors came from the trees.
When I was young, I was huge,
As I gained strength, I lost weight,
Now I am 1000's of times stronger, but you can barely see me.
What am I?
