They'd succesfully managed to send a message back
and had arranged a rendez-vous point. All had looked hopeful.
They'd thought that sending children might help; might tug at the heart strings; might make people listen. “From the mouths of babes”, that sort of thing.
And when their ambassadors; a four year old boy and a five year old girl dressed in shining, golden one-piece suits, stepped out of the time machine, there were people there to greet them; important looking types in dark grey suits and black sunglasses who they thought might be from the U.S. government of the early 21st Century.
“We humbly welcome you”, said one of the men with a smile that seemed sincere, reaching out a large, firm bear paw with which he shook their tiny doll like hands, “Travellers from our future”.
“Good. We have an important message for humankind”, said the girl, who obviously, judging by her vocabulary, had an IQ far above that of an ordinary 5 year old, “And we hope people will listen. About what pollution and global warming will do to the planet and all the people; the millions of children like us who’s lives will be lost if the people of your time do not stop burning fossil fuels”.
There was a moment of tense silence among the men and then the children were escorted, by the man who had shook their hands, into the back of a stretched, black limousine.
“Do you gentlemen work for the government?”, asked the little girl, gazing up at the other suited men in the back of the limo with wide, brown, innocent eyes.
“Oh no”, said the man, to her right, smaning and smiling cruelly as he placed a heavy hand over her screaming mouth, “We represent the oil companies”.
No one knows what happened to those two children, but they were never heard of again.
