Branding glass-coated kite string as 'highly dangerous', the National Green Tribunal (NGT) on Monday asked counsel of Gujarat government and string-makers to file response in the regard.
The tribunal has given four days time to the Gujarat government and string-makers to file their responses.
The matter will be next heard on February 16.
The NGT on February 1 asked to bring samples of glass-coated cotton thread, known as 'manja', for flying kites to show if it poses a danger to humans, animals and birds.
A bench headed by NGT chairperson Swatanter Kumar sought demonstration of glass-coated cotton thread after a dispute arose between the states and PETA regarding the issue of harm caused by the sharp string.
In its petition, PETA has contended that 'manja' posed a grave threat to humans and animals as every year a number of deaths are caused by it.
PETA had also asserted that children were engaged by the cottage industry for the manufacture of 'manja' which caused respiratory problems as they inhaled harmful substances which were extremely detrimental to their health.
