Bamboo

Bamboo has been greatly associated with Indian culture. We use bamboo for house construction, for making paper etc. It flowers and set seeds once in 40to 50 years. During the flowering season, occurrence of famine is noticed. What may be the reason? The rats are attracted towards the protein rich seeds of Bamboo and the rats multiply enormously. as the seeds are exhausted the rats turn to food crops like paddy potato etc. which may cause famine in older days.
