    Question

    Which of the following are the better household practices:

    1. Avoid setting fire to garbage, dry leaves
    2. Use of gas-powered lawn and gardening equipment
    3. Compost your yard waste
    4. All of these

    Hint:

    Household wastes means kitchen-garden wastes.

    The correct answer is: All of these

      Avoid setting fire to garbage, and dry leaves, Use of gas-powered lawn and gardening equipment, and Compost your yard waste are the better household practices.
      • Smoke from burning leaves contains numerous toxic and/or irritating particles and gases. Small particles in smoke from burning leaves can collect in the lungs and remain there for years.
      • Gasoline lawns and gardening supplies emit air pollutants such as carbon dioxide, carbon monoxide, hydrocarbons, volatile organic compounds, nitrogen oxides, and particulate matter. Some of these air pollutants contribute to ground-level ozone and haze formation.
      • Composting is effective for most garden waste, including leaves, vegetable and flower plant parts, straw, limited amounts of stumps, grass clippings, and weeds. Woody twigs and branches larger than 1/4 inch in diameter are passed through the shredder chipper first.
