10 Amazing Facts about water crisis

🌕 Nearly 2 lakh people die every year in India because of consuming contaminated drinking water.

🌕 A 2018 paper published in the Journal Of Hydrology by IIT Indore researchers found that only about 32% of India’s landmass is resilient to water stress during

the course of a single dry season.

🌕 India, the world's largest groundwater consumer uses around 230 cubic kilometres of groundwater in a year.

🌕 According to NITI Aayog, Groundwater which is the source of 40% of India's water needs is depleting at an unsustainable rate.

🌕 India, the world's largest groundwater consumer uses around 230 cubic kilometres of groundwater accounting for 12% of global groundwater extraction in a year. At this rate by 2030, nearly 60% of India's aquifers will be in a critical state.

🌕 Out of total available groundwater of 253 BCM (billion cubic metres), agriculture (irrigation) alone consumes around 90%

🌕 Groundwater resources are overexploited in nearly 17% of total assessment units (blocks, talukas, watersheds etc) in the country : Jal Shakthi ministry

🌕 Nearly 13.8 crore household that comprise 16 crore people lack access to safe drinking water.

🌕 Niti Aayog's Composite Water Management Index (CWMI) report, pointed out that the country's water demand is predicted to be twice the supply available,

implying a subsequent 6% loss in GDP.

🌕 Forest Fires -- According to World Bank report Strengthening Forest Fire Management in India:

Why do the Indian telecom operators offer their services with 28 days validity, not 30 days?😡😡

Here telecom operator are very clever, b ecause telecom operators want to earn money of 13 months instead of 12 months. Let do the calculation and find out why telecom operators are offering 28 days validity. Each month they get 2 days more, therefore in a year they get additional 24 days. There are 7 month which has 31 days so they get additional 7 days.Now in case of February ,it has only 28 days not 30. So the total number of days they get are=24+7-2=29 days. So if you recharge 12 times then more 29 days are left in a year.🤔🤔 Means for another 29 days you have to recharge from that telecom operator.😫😫 So you have to recharge 13 times in a year instead of 12 times in a year. So telecom operators provide 28 days validity only. First one telecom operator started and then another telecom operators also understood this concept and they also applied 28 days validity both in data packs and voice packs.😱😱😱

What is the best way to set up the information to be transmitted to give the maximum information transfer across a given channel?

This is of interest in many applications; an example is sending a large document by email. The document may be several hundred kilobytes in size and to send it by email over a telephone line using a modem operating at 28.8 kbps may take a considerable time. If the data are compressed, the file can in certain cases be reduced in size by a factor of over 10, which would reduce the time taken to transmit the file, thus improving the convenience and minimizing cost. If the source information contains redundant information, data compression can shorten the message by removing redundancy. An example would be sending a text file over a communications link where the source device removes redundant characters before transmission. If the file contains sequences that are repeated, such as several space characters in a row, then instead of transmitting each of them the number of spaces could be transmitted. At the receiver the reverse process would allow the original document to be recovered. This...
