B. Manimegalai, president, Central Government Women’s Employee Association, Shastri Bhavan, Nungambakkam, delivered a lecture on the ‘Usefulness of Birds in the Growth of Plants’.
She urged the gathering to place water in bowls for birds. “Many factors are attributed to the dwindling population of house sparrows. Lack of open space, rise in the number of high-rise buildings, increasing use of pesticides and insecticides on fields and gardens, radiation from cell phone towers and rising pollution levels,” she said.
People should grow more fruit-bearing trees to conserve and protect the species, she added.
Garden experts were present during the sale to give guidance on gardening, urban farming and composting.
Free Nochi saplings, sponsored by Chennai Corporation, were distributed to more than 100 people.
