Research, Education and Conservation are the key functions of any botanical garden. Almost all the botanical gardens in the world preserve several plant species to protect Biodiversity. Besides, many botanical gardens in the world have plant shops selling flowers which are economically significant. Have we ever thought why the Earth’s ecosystem has become exaggerated? The cause is rapid industrialisation, urbanisation and overpopulation.  They pose threats to our ecosystem.

How can we minimize these threats?  Botanical gardens can minimize these threats by providing a medium of communication between the general public and botanical science. It’s a matter of regret that many botanical gardens have become closed for lack of financial support. Nowadays the reputation of a botanical garden is judged by the publications from herbarium instead of focusing it’s living collection. Government and NGOs should come forward to protect their botanical gardens.
