It all depends on what the individual is prepared to accept or put up with really .
Yes we eat chemicals and poison the soil , the sea , the air every day , but we are all still here , not really the answer is it ?
Yes we are still here , but how many get cancer , or other terrible things ?
Fish in the sea are part plastic now , due to the breakdown of plastic , (that we dump in the sea) , into microscopic particles .
The list is endless .
Even fresh spring water off the shelf in 'plastic' bottles , contains certain poisons given off by the plastic .
Food grade plastic is better than other types , but even babies bottles leach poison chems , as does the container the milk power is in !
Tyres leach out chemicals for sure , i did look it up once and would rather not put the chems in the soil , then into the plants and thus into me , but that is my choice .
I am trying to be as free as i can of man made chems/poison , it isn't easy , but growing my food in it when the soil is underneath seems a bit strange to me .
Saying that , i do have some plastic flower pots that i use . I used to only use clay pots , but they are so dear now , and i have no money ( my choice , i did say it wasn't easy ) , i use s/h plastic pots when i have to .
I mainly try to grow directly in the ground though .
Personally , i limit the poison i eat as much as i can . Some people pump roundup over their ground wtf ? , but that is their choice . Even that affects other people though , run off into ditches , streams , the water table etc , but Monsanto says it is safe , yeah !
20% of agricultural land in China is contaminated with heavy metals , industrial pollution , i bet the figure is higher than that , yet they are still here , doesn't really answer the problem as far as i am concerned .
Not having a dig at anyone . Just saying i try not to use things like tyres and why .
Like i said we all have different levels of acceptance .
