Look at this and really look at it calmly and gently and closely.
Then if you can be bothered, think about how that fresh lovely breathable air has over A BILLION cars and trucks pumping poisonous and hot CO2 into it all day, all night 24/7 come rain or shine winter summer, whenever. Don't forget all the lawnmowers and scooters and chain saws.
Then think about all those POWER STATIONS pumping hot coal and oil exhaust gases into the atmosphere all day all night etc etc
Then think about all those thousands of Hectares of trees that are cut down, every day, all night and all day long and then
Think how long does it take for HUMAN BEINGS to open their eyes and stop ignoring what is the utterly bleeding obvious that no one needs a scientist to measure and to tell them? Think about that thing that a five year old can figure out and then ask yourself why do we keep doing it? Why are we so stupid?
ALL THAT GAS being pumped into the air we breathe is killing the planet's ability to sustain human beings and all the other mammals, and fish and and and if you can be bothered, think about the weather.
And then DENY CLIMATE CHANGE IS CAUSED BY US.
