Vandalur zoo's "night safari"?

I read this news item today and it set me thinking.

A senior officer said 124 mammals, 124 birds and 42 reptiles, totalling 290, would be exhibited. As per the plan, the authorities would source an adequate number of birds, mammals and reptiles from the zoo, and the rest would be acquired from other zoos in the country under an exchange programme.

The safari area required 20 lakh litres of water every day. For this, the officials proposed to draw seven lakh litres from the ground, and 6.5 lakh litres from the Palar and Veeranam. The rest would be treated water that would be obtained from Perungudi.

The facility needed 5,000 MW of power. The cables for power supply would be laid underground. For viewing the animals, special lightings would be provided, but they would not disturb the animals. To overcome disruption of power supply, a back-up facility would be created with silent generators.

First we, as a race, set about destroying forests, killing wildlife and generally making a mess of the planet. This results in a situation where mankind cannot see wildlife in any place on this planet except in zoos that are built in the name of wildlife preservation. Then, we go about building night safaris that use over 20 lakh litres of water every day and 5000MW of power - further destroying nature. I'm not an expert on such issues but I'm guessing that 20 lakh litres and 5000MW of power could be put to better use.
