From Satyug to Kalyug , there has been a slow , but incredibly vast change in different things. Degeneration in the way of living , knowledge and wisdom. There has been decline not only in the morality , but also in the mental and physical strength of an individual. Do you know that average people used to live for 100,000 years in Satyug?
Then it decreased to 10,000 years in Treta Yuga( Shri Ram ruled in Ayodhya for 10,013 years). In Dvapara Yuga , the average age of a human was 1000 years . The life expectancy has gone below 100 years nowadays , or in Kalyug. It it said that it will decrease to about 50 years in the upcoming future. Average Human height will deteriorate , too.In Shrimad Bhagvatam it is mentioned that in Kalyug people will destroy the natural resources so much that it's outcome will come in the form of severe cold , floods , heat , rain and snow. People will suffer from diseases , hunger , thirst and mental illness.
Moreover people will no longer take care of their parents.They will leave their elders alone on themselves. People will become so much hateful that they will fight for a few coins of wealth , or anything of their desire. They would be ready to die themselves or kill someone to fulfill their needs. There will be no more greenery left on Earth. People will have to eat rotten food which will be mostly derived from animal flesh.
It feels strange because most of the things written in the Puranas and scriptures are getting true , moreover worse nowadays. Isn't it ?
