Public Health workers are trained to remove all the grass besides the road boundary. They feel it as 100% Solid waste Management. In all the municipalities I worked , i instructed to stop the removing of grass on the road margins.
There are many advantages of up keeping the grass on road margins as follows :
1.It avoids the soil erosion .
2.Sucks and upkeeps the water during the rains.
3.It captures the solar insolation and avoids warming.
4.It allows at least small amount of sucking of corban dioxide and release of oxygen in to air.Thus ,reducing the pollution.
5.Grass is source of insects.Dragon fly , frogs eats these insects and also eats the mosquitoes as well. Thus, grass can indirectly reason for mosquitoes control by providing food for the mosquito eating insects. Also ,it is reason for biodiversity. Lack of grass, food chain has been disturbed in urban areas.
So, all the municipal officers should recognise the importance of the grass on the road margins and issue instructions not to remove the grass in the interests of environment Protection.
Ayyo gaddi kadha pikithe emautundante, tharuvatha pikadaniki gaddi kuda undadu. (What happens if I remove this useless grass, later you will not left with any work.).
I also share my experience that I was a regular visitor of the Compost yard of suryapet, during my tenure. Whenever the dragon flies( Booga in Adilabad district, tummiska in Nalgonda district and khammam districts, Tuniga in Andhra area) were existing, there were no mosquitoes were existing in the suryapet compost yard.On one day I noticed a lot of mosquitoes in the same compost yard. It due to the absence of the dragon flies.My elders also told me that dragon fly eats the mosquitoes. Now ,the eating of mosquitoes by dragon fly is part of curriculum for 4th class students.
