Aliens save the world

“Look, it’s over there!” squeaked a squat figure with bushy, green hair and a crumbling, brown body like a tree bark,pointing excitedly at a blue ball spinning in an endless pitch black lake,“I see planet earth!” Identical creatures to the one who had just spoken,rushed to the window, pressing their wrinkled hands on the glass,their tennis ball sized, bright eyes wide open. “Reduce Speed! We are entering the earth’s orbit,”ordered the largest alien in the spaceship,handing over a metal object which sparkled like a diamond. It had six rubber buttons with different letters embroided in red on them.The other aliens squabbled excitedly among themselves while Polez pressed the buttons. “What’s it like there?,” Zolez asked Golez, who was the only one who had visited earth before. “Earth is the best.It has lots of different landscapes and creatures, humans,are the most intelligent.” replied Golez, then shaking his round,green head,he said,"but they don't seen very grateful .They don't look after it and do terrible things such as dropping litter and killing other creatures. Our mission is to change their ways before it's too late,"
Meanwhile,three boys wearing hooded jackets and ripped jeans strutted down the street,dropping litter all over the place. A plastic bag drifted to the nearby pond in which swimming peacefully,with white beautiful feathers was a swan.The swan dipped it's head into the murky waters of the pond and suddenly emerged,flapping helplessly.Her head was stuck in the bag. They laughed,"you pathetic bird!"then started pelting the bird with litter. "Simon!"called Thomas,pointing at the sky.
"Chuck bricks at it to bring it down,"said Simon. The boys,who had no respect for anything,picked up the pieces of brick from the crumbling walls and flung them at the spaceship.CLANK.A particularly large brick smashed the wings of it,causing it to hurtle down.The doors opened and Golez,followed by the rest, stomped out furiously. Polez pointed his metal object at the shocked boys. Helplessly as the swan, they tried to move. "The technician snorted ,"You are paralyzed.Your behavior is antisocial and unacceptable.You damaged our spaceship and the swan. What will you do about it?" "We are very sorry, we'll help you fix it" they stuttered terrified.When they were released,the boys enjoyed helping to fix the spaceship. "Wow, this thing is actually pretty cool!"said Thomas. "What on earth are those!I'll just clean it up with my astrol spray," screeched a lady in a stuffed vulture hat."Achoo! Achoo! God This thing always makes me cough!" The aliens explained to Mrs Mozzy that astrol spays harmed living things and that it was cruel to kill animals. Next,the aliens visited some gangsters who were driving a car. "Come on! Come on! Drive faster!" shouted one. The aliens were appalled. "Sir you must stop at once!" squealed Golez bravely,"You are polluting the air,why don't you just walk or use a bus?" "Good idea!Come on guys get jogging!" said the gangster. The next day everyone gathered around the spaceship to say goodbye tearfully and promised to look after the world.
