The warming planet

In the heat of summers
it was nice to bathe in the river
ten minutes from the houses.
A great place to cool off
Not crowded by tourists.
Cigano boys bronzed
And physically perfect
Diving from the branches
Of the generous oak.
Of the warming of the planet
I know little, only this
The river is dry as early as May
been so, for five years.
But old people, tell me
It has happened before.
The river, near the houses
Were dry for years
In the fifties.
