Answer 7

Let me think now

.. . ..

The wheel is when it started to go down the tubes

.. .. .

The rocket is when it went the pollution of man went to the moon and Mars

.. .. ..

So what is the one thing that man did to make things better

.. . ..

Nothing there is not one thing that mankind has done that has had a 100% good effect on the earth

Everything that mankind has done has something connected with it that has caused destruction polution or something else that make things worse
