The tours are preceded by an interactive session with the students, which brings out the students' perception of the environment, and their notion of development and progress. This is followed by interactive discussions that draw many interesting responses. Experts from other NGOs and government institutions accompany the children on the field trip, and fact sheets and informative poster kits are distributed amongst the students. An audio-visual show on each issue is presented before each trip. We offer a choice of five educational ecotours in Delhi: Yamuna Yuk Ride: The Yamuna is one of the many 'sacred' rivers of India. The city of Delhi depends on the Yamuna for its water needs, yet it is one of the most polluted, with Delhi's pollution load virtually killing it. A boat trip down the polluted Delhi stretch, to create awareness about the state of the river. Water walk: The ingenious water harvesting structures Delhi contains were built over the centuries to ensure against drought and invasion. This tour creates awareness about the history of water use in the city, the conservation and revival of these structures, and relates it to the existing water problems plaguing the city. Jungle Jog: Nature walks in the Ridge Forest to understand the role of an urban forest, its flora and fauna and conservation. We're also starting overnight camps. Raising a stink: The ecotour entails visits to landfill sites and recycling plants, meetings with ragpickers and NGOs working on the issue of waste to get students understand the enormous problem of waste disposal in a metropolis, their role in waste generation and disposal. Sanitation: A visit to the Sulabh international toilet museum to understand sewage and toilet systems, state of scavengers, and to understand how our toilet habits are connected to the wellbeing of the environment. We'll also be starting eco-tours to a car manufacturing unit and a water treatment plant.
