Biodiversity and its conservation: - Introduction, definition, genetic, species & ecosystem diversity and biogeographical classification of India (जैव विविधता और इसका संरक्षण: - परिचय, परिभाषा, आनुवंशिक, जातीय व पारिस्थितिक विविधता और भारत का भूगोलिक वर्गीकरण):-

Biodiversity (जैव विविधता):- It is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species and ecosystem level.

(यह पृथ्वी पर जीवन की विविधता और परिवर्तनशीलता है। जैव विविधता आनुवंशिक, प्रजाति और पारिस्थितिकी तंत्र स्तर पर भिन्नता का एक माप है।)

> Scientists have estimated that there are around 8.7 million species of plants and animals in existence. 

(वैज्ञानिकों का अनुमान है कि लगभग 8.7 मिलियन पौधों और जंतुओं की प्रजातियाँ अस्तित्व में हैं।)

> However, only around 1.2 million species have been identified and described so far, most of which are insects. This means that millions of other organisms remain a complete mystery.

(हालांकि, अब तक केवल लगभग 1.2 मिलियन प्रजातियों की पहचान और विवरण दिया गया है, जिनमें से अधिकांश कीट हैं। इसका मतलब है कि लाखों अन्य जीव पूरी तरह से रहस्य बने हुए हैं।)

Types of Biodiversity (जैव विविधता के प्रकार):- 

i. Genetic Biodiversity (आनुवंशिक जैव विविधता)

ii. Species Biodiversity (प्रजाति जैव विविधता)

iii. Ecological Biodiversity (पारिस्थितिक जैव विविधता)

i. Genetic Biodiversity (आनुवंशिक जैव विविधता):-
