1) A group of 50 techies from TCS volunteered on a Saturday to help maintain saplings and clean up an area near Gunjur Lake in Bangalore that was once a lake but had dried up due to development and soil theft. 2) They met with an environmentalist named Mr. Khan who runs a local school and has been working to restore the lake area by planting saplings. 3) The techies helped maintain the saplings while getting exercise and fresh air in contrast to their typical workweek spent indoors. They saw examples of environmental restoration and waste reduction efforts by Mr. Khan's school that gave them optimism about environmental causes.
