For whom and for what does it breaks down? (I'm not only talking to
you Martin, you understand). Is it to plant a petunia after
eliminating an unsightly taraxacum or to provide 200 tons of potatoes
to feed the starved? What does it take for people to understand the
cycle of life? What does it take to make people who love their garden
understand that even the smaller amount of chemical will have
inevitable desastrous consequences either by the reduction of insect
populations which will in turn impact on birds and mammals that feed
on insects?!! How can anyone call themselves a lover of nature, a
gardener and justify the use of chemicals in their gardens?! Ever?!?

Science Society Sustainability said about the threat of glyphosate
when speaking about genetic modification in forest trees: Glyphosate
is the most frequent cause of complaints and poisoning in the UK.
Disturbances of many body functions have been reported after exposure
at normal use levels. It nearly doubled the risk of late spontaneous
abortion, and children born to users had elevated neurobehavioral
defects. Roundup (Monsanto's formulation of glyphosate) caused cell
division dysfunction that may be linked to human cancer. Glyphosate
caused retarded development of the foetal skeleton in laboratory rats.
It inhibits the synthesis of steroids and is genotoxic in mammals,
fish and frogs. It is lethal and highly toxic to earthworms.

Glufosinate ammonium is linked to neurological, respiratory,
gastrointestinal and haematological toxicities and birth defects in
humans. It is toxic to butterflies and a number of beneficial insects,
also to the larvae of clams and oysters, Daphnia, some fresh water
fish such as the rainbow trout. It inhibits beneficial soil bacteria
and fungi, especially those that fix nitrogen".

Find below countless photos for all of you parents and especially
grandparents, find articles and reports showing children born without
arms, legs, eyes ... and as I write this hundreds of children are born
from poor families working in fields using weed killers and pesticides
so that we can get some Fine Green Beans in Sainsburys next January.
Please take a second, especially those of you who are still using
chemicals in your 10sqm back gardens because you just can't stand
taraxacum. For every time you use chemicals, you kill not only a weed,
but hundreds of insects, countless birds and a child.
