NOAA CWCP base on 50 acres area . 24 acres for building , 26 acres for grassland .

So first they need to re - create the 26 acres become grassland + ( 300 trees / per acre * 26 )

And because of A0 = A1 " + " A2 . If the Earth only have 1 building create CO2 pollution , so even they we have more 26 acres back to normal ( we must wait about 15 years for all the trees become adult so they can absorb 48 lbs CO2 per year ) , we lost 24 acres for the building , 24 acres never can absorb CO2 / water as the past . So we need more 24 acres of grassland + ( 300 trees * 26 acres ) . We use area for building , we must have another area with same size for replacement .

And for pollution of 800 cars , we need more area with plants to absorb CO2 of 800 cars . Relly plant more trees or plants , and not base on the original Earth - Original Earth don't have 1 building NOAA CWCP .

So how many State of US have a rule : you spent 1 square foot for the building , you must find another 1 square foot don't have trees , plants and then plant trees / plants for replacement 1square foot of building you build .

And the owner / company / org of the building must solve CO2 of cars of employees .

We build a city near a forest and then increase the size of the city , destroy forest , the area of the city ( house , road , buildings , ......... will under cement , stone , .... not asorb CO2 / water anymore ) . We need absorbing source of CO2 / water for replacement . All countries did it , all countries have the same !!!!

. Where is my absorbing source of CO2 / water for replacement when they destroy forest for EPA buildings ? This is what a United States Environmental Protection Agency can do in Climate Change ?

Even CO2 of cars , nucleAR POWER PLANT , Coal power plants , planes , ... become 0 , we still make Climate Change .

Next will be a exercise .
