All human activity, factories, cars result in CO2, which forms a layer with all the other green house gases above Earth's surface. This traps heat close to Earth, resulting in rising temperatures.
This is unexpected... I never knew how much harm we do to our planet!
I must warn the others! Before this gets out of hand!!!
I must warn everybody! My family, friends, everyone on this planet! By 2065 we'll be dead!
The robot began explaining how human activities result in rising temperatures, and the green house effect. John was very shocked how humans were technically killing themselves!!
We must stop global warming! By 2065, there will be no living things!! Tell everyone.
We will let everyone know! Let's raise awareness!!
John wanted to raise awareness about the issue as soon as possible, so he entered the time machine, and went back to the present time.
Have you guys heard about the future?
Yes this is terrible! Everyone is talking about it.
He was on his was back to the present time, to warn others about the damage they have caused.
What you did was great! You are the reason people, animals, and plants will live in the future. One small thing you did, makes a huge difference...
John started spreading awareness about the issue, and informed everyone how their daily activities cause global warming and will then kill all animals, plants, and humans by the year 2065.
The message spread between everyone, as all people were speaking about the issue worldwide.
In his dreams, John saw the robot he met in the year 2065, as the robot told him how he made a huge difference that will benefit all living things in the future!
