Pandas are known as the animal who eats bamboo.
Bamboo shoots are not rich in many nutrients, and therefore pandas can eat up to 12 - 15 Kilos of shoots in 1 day! They eat for over 12 hours a day.
Pandas eat almost nothing but young bamboo shoots and leaves.
Pandas need at least 2 different bamboo species in their range to avoid starvation.
Instead of using this highly important food source for endangered animals like pandas, IBANSS uses mature bamboo, which no species of pandas eat, and therefore does not affect the food chain in any sort of way.
This generates livelihood for the farmer who has been growing bamboo for a long time, and has no use for it.
