Sir: Dolphins are very intelligent and they seem to be loved by humans. There are 43 species of dolphins found in the world. They are very smart and understand the concept of numbers. Dolphins may be well loved by many humans due to their playful actions and intelligence, but they are also at risk due to humans. It is sad to mention that this beautiful creature is not only ignored but also being killed in Pakistan. Moreover, a report says that 12,000 dolphins are being killed in Pakistan every year. The government is requested to save this beautiful creature from the risk of extinction. PARI TAHIR Turbat
