( Please correct me if I was wrong )

( Our forefathers , ancestors should know this truth thousand years ago , ..... sadly )

A Earth before human kind appear is fresh by large amount of plants around the Earth . Human appear( 1 ) . We change the Earth , build house , road , building , airport , stadium , ............ exploit wood ( 2 ) . And we , our cars , bus , plane , gas , oil .....create CO2 ( 3 ) .

Here , just focus on O2 , CO2 , water of area :

( 1 ) This is a environment before human appear :



We mainly choose to build society near a place have water , rivers and that place will have plants . Or original Earth , original area have plants . Or original Earth , original area create O2 , absorbs CO2 / water . Than we build our society :

(2 )




Ex : we use 100 square acres for a building , 50 acres for a building , 50 ACRES FOR GRASSLAND . 100 acres in the past have adult trees , wild grass . So if we restore the environment after build the building , we MUST MAKE 50 ACRES IN PRESENT ABSORB CO2 VALUE = CO2 ABSORBING VALUE OF 100 ACRES OF TREES + WILD GRASS IN THE PAST . It’s meant about value of CO2 , O2 , water , after human use this area , it’s doesn’t change . It’s equal between past and present . Human don’t decrease absorbing CO2 , water , creating O2 value of that area . If after human restore the 50 acres and absorbing CO2 / water , creating O2 value less than 100 acres of the past , so we must find another area and create plants that absorb CO2 / water , create O2 in supply for the absorbing CO2 / water, creating O2 that we need , want . CONSERVATION OF CO2 , WATER , O2 .

Have you ever stand in front of a row of trees ,on the left are some skyscrapers , on the right is a road . Just imagine the environment in the past of area of all building’s size , the floor and the environment of the road . So the question is : The value of absorbing CO2/ water value , creating O2 value will equal with value of absorbing CO2 /water , creating O2 of the area of all skyscrapers ( left area ) add with the area of the row of trees in the past , what was here ( between ) add with value of absorbing CO2 , water , creating O2 of the environment of the road in the past ( right ) . Think about CONSERVATION OF CO2 , WATER , O2 .

We build a lot of roads . And a road go through a wild grass area , bush trees , a forest . Roads decrease of absorbing CO2 , water , creating O2 value of wild grass area , forest , …… We don’t have a CONSERVATION OF CO2 , WATER , O2 .

Have you ever see aairport ? No plants at landing field .If we destroy all plants for airport . We should find a empty place , and plant any kind plants , to make it replace absorbing CO2 , water , creating O2 value = value of absorbing CO2 , water , creating O2 of the airport’s environment ( plants )in the past .

And many things more , ………

All the process is 100 % comparison of absorbing CO2 , water , creating O2 value of the past and the present , for CONSERVATION OF CO2 , WATER , O2 .

All CONSERVATION OF CO2 , WATER , O2 of buildings , roads , house …. Add with CONSERVATION OF CO2 , WATER , O2 of forest we destroy , exploit for wood .
CONSERVATION OF CO2 , WATER , O2 of buildings , roads , house , forests , ….. => CONSERVATION OF CO2 , WATER , O2 of town , city , state , ……. => CONSERVATION OF CO2 , WATER , O2 of country => CONSERVATION OF CO2 , WATER , O2 of Earth’s plants .

After we have CONSERVATION OF CO2 , WATER , O2 of Earth’s plants . ( original Earth )

Add with :
(3)

We know cars , bus , ship , plane absorb O2 , create CO2 , CO2 of fossil fuel , gas , …….. So we must have area of plants for of absorbing CO2 , creating O2 if we don’t want CO2 from these things are our problem .

The architecture don’t know about CONSERVATION OF CO2 , WATER , no one know it before .

And no one can confirm land , soil in a city , town which under asphalt , rock , boardwalk , …. Will absorb , store CO2 equal with natural land , soil before we build city , town ( plants have root , root make land become good quality , and which asphalt , boardwalk , stone , brick above , no plant’s roots under it )

Just walk into town , city , look around and calculate . Even your city , town design with 70 % for plants and 30 % for buildings , house , it's not correct .

Even how large average plants size per each persong you have , it's not base on CO2 , O2 , water . Plants have different type , some absorb a lot of CO2 , some are just for fun .

So things are not simple .
