hindi should be the national official language

Hindi is defined as (1):the most widely spoken language of northern India, with over 200 million speakers; one of the official languages of India. It is an Indic language derived from Sanskrit and is written in the Devanagari script.As I can agree with that statement of 'Hindi is the most popular language in India' it doesn't make up the rest of the world. Given that 60% of people speek Hindi there, that is 6/10 of India, let alone the whole world itself. In a matter of fact, (2) shows what languages are most popular worldwide:1. MandarinThe first ranker language in the whole world is Mandarin. This language is mostly spoken in china, Taiwan, Malaysia and Singapore. Mandarin has more than 1000 million native speakers. This large no. of speakers made this language as the most spoken language in the world. If we talk about the percentage total then, in the whole world population, 14.1% people speak Mandarin.The main reason behind the large native speakers of Mandarin is the area of that country where this language spoken widely for example, china, the third largest country of the world and also is the biggest populated country of the world.2. SpanishThe second most probably spoken language in the world is Spanish. This language is mostly spoken in Hispanic America, United States, Spain and Equatorial Guinea. More than 410 million people speak Spanish as their native language and this total no. of Spanish native speakers covers a 5.85% of the world population. Now, we can say a large no. of people speak Spanish as compared to another languages.3. EnglishThe third most spoken language of the world is English. The countries in which this language is mostly spoken are Australia, Canada, Ireland, New Zealand, United States, United Kingdom and South Africa. More than 360 million speakers speak English as their native language. And this total no. of speaker covers about 5.52% of the world population.We all know that the English is an international language, hence used everywhere. But here we mentioned about only those countries which speaks English as their native language.4. HindiThe fourth most spoken language is Hindi (Hindustani Language). Hindi is mainly spoken in India. We here included all variety of Hindi languages which are mainly spoken in India for example Main Hindi, Haryanvi, Hindi-Urdu, Awadhi, Chhattisgarhi, Bagheli, Marwari, Magadhi, Bhojpuri, Kumauni, Pahari etc. more than 300 million speakers speaks Hindi as their native language. This count of native Hindi speakers covers about 4.46% of the total world population.The one best reason for the large no. of Hindi speaker is the population of India. We all know that India is second largest country in term of population.As you can tell, Mandarin, Spanish and English are more preferable than Hindi. Plus, hy should we disreguard all the other languages all around the world? What about the fewer tribes left that speak unique languages? Why should everyone speak the same? I believe, that if we all spoke the same, looking forward to trips (tourism) and learning about new cultures and languages could be a problem. How am I meant to learn French at school if no one if ever going to speak it again? Overall, we certainly should all have our individual language and feel free to speak in any way we want to. It will increase tourism (rather than decrease) and there is always money coming in to see cultural events. We never should say we have to speak one language. We have the freedom and right to, don't take that fact away.Sources:(1) http://www.google.com.au... (2) http://www.listsworld.com...
