Its indeed very sad that tourists don't behave when inside the forest. I visited Tadoba earlier this year and was very depressed on witnessing the dismal attitude of some of the tourists. Some of them wanted a rest place and eating and drinking facilities inside the forest.
One more thing what I observed was that some of the if tourists failed to spot a tiger they came back and were like there is noting inside the forest. They fail to understand that there are lot of other species of plants and animals too.
Spreading awareness will surely help the cause.
