Answer 2

I am the alien from "Brainly "planet. My name is "The benefecator "Let me narrate you my visit to earth. We in our planet have heard that The earth is a special planet. We also heard that "There are intelligent humans on the earth". We thought "Earth was a safe and,happiestplanet. We wanted to occupy the earth because of its good nature. But my opinion changed with my visit to Earth.I with my space craft has landed on earth. But when we were landing we were troubled a lot with smoke. The source of that smoke was unknown. As we landed, we saw many humans. Firstly we saw that Trees were producing oxygen. But the saddest thing we saw was Some of tress were cut down for some cause. That cause was,know to us later. The people cut off the tress,for homes, furniture etc. They are cutting their own lungs. As we knew trees are producing oxygen required by them.Later, we went into water through our space craft. When we were in our planet, we knew that "Earth has pure water ".But the thing we say shocked us 
The water was being wasted in a huge manner. It was also not pure. Then we went further deep into the water,we discovered many dead remains of fishes,which found to be dead some 100 years ago. The cause which we came to know later was due to oil spills. We gathered information on that. We came to know that humans on earth use fossil fuels, which while transporting, fell into water. We finally came out of water. Then we were on a plan to go into habitats of humans in disguise. We saw that many were misusing two things. one was water. The other was food. We,in our planet brainly, value for each and every thing. We respect food as much as we respect our lifes.The major thing we saw was taps left running,taps leaking. We later saw that some producing shops which were named " Factories " were releasing some harmful gases which impurified the air.The waste without treatment was left into water. The final thing I want to say we discovered "POLLUTION "in earth. If they continue their work they may get two things. One is global warming. The other is ozone layer depletion. If global warming happens they get extinct. If the ozone layer depletes the ultra violent rays enter in earth and destroy the planet. The information and terminology was given to us by two scientists 1)Praneeth 
2)Govind krishnan.The one last thing I want to say "Don't pollute your resources "If the times passes, situation gets worse. so it is the right time to awake and save yourself from destruction. Protect, conserve before its too late. 

Hope essay helps you.
