The zoo teaches environmentalism both in its exhibits and by personal example.
Since 1997 it has featured an "ecological maze" – a short path meandering through high bushes with signs that highlight ecological challenges in Israel.
In spring 2010 it unveiled a $1.5 million aquatic exhibit called "Wet Side Story" which stresses the importance of water conservation, ecology awareness, and water challenges in the Middle East and around the world.
This exhibit displays rare and endangered marine life in 17 large aquariums and three huge water tanks measuring 2 x 4 metres (7 x 14 ft).
There is also an outdoor "petting pool" where visitors can touch and feed koi.

In keeping with its "green" policy, the zoo maintains its own sewage treatment system and uses recycled water to irrigate its gardens.
Food and animal waste are mixed with plant material and placed in large compost piles; the compost is used to fertilize the trees and shrubs.
The zoo sells its organic compost in the gift shop.
In 2006 receptacles for collecting used plastic drink bottles were installed next to each of the snack bars, and used batteries are collected at the gift shop.
To reduce carbon emissions and traffic, the zoo schedules the use of delivery and security vehicles.
