We seem to be bullish on wildlife this week. Two prominent developments have given those who are inclined towards environmental issues much heart. First up is Prime Minister Narendra Modi featuring in a special episode of Discovery's Man Vs Wild to air on August 12.

Then a roar of approval for a four-year tiger census report, known as 'Status of tigers, co-predators and prey in India' released this week. It shows a huge jump in tiger numbers across all landscapes in India from 2,226 in 2014 to 2,967 now, a rise of 741 individuals in four years. In percentage terms, it works out to 33 per cent.
