Lenin's birthday
Here we see about 100 middle-school kids walking to school today to "celebrate Earth Day."
Well now, let's see how much energy they're saving. Assume they're 7th graders. Today would be about their 1400th day of school. (180 days per school year * 7 full years, plus about 140 this year.)
Until today (and again after today!) each of them has been ferried back and forth in Mom's SUV. Mom's SUV is rated at 17 miles per gallon, but the way Mom drives it's more like 12. 1400 trips of about 4 miles = 5600 miles. 5600 miles / 12 MPG = 466 gallons. So all 100 kids have used 46600 gallons of gas up till today.
By walking today they saved 33 gallons altogether. Roughly 7 hundredths of one percent of their lifetime total up till now.
Even if you buy the Carbon Cult's monstrous structure of genocidal lies, this is completely trivial.
Far more important, but not even mentioned in the Earth Day ratshit:
If these kids walked every day, they'd live longer, better and saner. With 4 miles of exercise and sun each day, they wouldn't need ADHD drugs. They'd be in closer contact with the physical world, they'd have a better understanding of seasons and proportions and causality, thus they'd be less likely to fall for fantastic evil propaganda like Earth Day.
