Devarabettas- Insurance against drought
Voluntary organizations, Government and forest officials all know that natural regeneration of denuded lands is a thousand times more effective than artificial afforestation, where protection and nurturing is almost impossible, survival is low, and pits or trenches for planted saplings often cause more soil disturbance and erosion than they are meant to avoid.
Mercury Pollution Prevention
One 40W tubelight contains 20-40 mg mercury, depending on the brand. This quantity, which is equal to the daily safe exposure limit for 4000 persons, is released within 8 hours of tubelight caps being removed on roadsides for the sake of recovering 50 paise to Re 1 worth of aluminium for sale for recycling. (Currently, unless analyses prove the contrary, I believe these mercury limits fall below the 50mg Mercury and mercury compounds limits forHaz-waste in Class A Schedule 2 of the Haz-Waste Rules).
