Growing plants helps the environment - They take out CO2 -Carbon dioxide, and give out Oxygen {O} in their respiration system in the daytime -At night time they just stop as photosynthesis ends - they do not reverse the process as that's an old wives tale....Late to this one but I’m not going near my garden until we swing back around on this rock us scum have cultivated on.
So growing plants is environmentally friendly - that's why parks in the Victorian era were so popular constructed in the large cities - why Avenues had trees etc etc....
All to clean the air ways even back then.....
