Question
Which of the following are the better household practices:
- Avoid setting fire to garbage, dry leaves
- Use of gas-powered lawn and gardening equipment
- Compost your yard waste
- 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.

The most important cause of air pollution is:
The correction of is c)Burning fossils fuels.
- Air pollution is a mixture of harmful substances from man-made and natural sources. Motor vehicle emissions, fuel oil and natural gas used to heat homes, by-products of manufacturing and power generation, especially coal-fired power plants, and smoke from chemical manufacturing are the main sources of anthropogenic air pollution.
- When fossil fuels burn, nitrogen oxides are released into the atmosphere, contributing to the formation of smog and acid rain. The most common nitrogen compounds released into the atmosphere by human activities are collectively called nitrogen oxides.

Burning of fossils fuels like petrol, and diesel causes:
The correct option is a)Global warming.
- Fossil fuels are formed by the decomposition of buried carbon-based organisms that died millions of years ago.
- They create carbon-rich deposits that are decomposed and burned for energy. They are non-renewable and currently provide about 80% of the world's energy.
- They are also used in the production of plastics, steel and various products. Fossil fuels include his three types: coal, oil and gas.
- When fossil fuels burn, large amounts of carbon dioxide, a greenhouse gas, are released into the atmosphere. Greenhouse gases trap heat in the atmosphere, causing global warming.
- The average global temperature has already increased by 1°C. Temperatures above 1.5°C increase the risk of sea level rise, extreme weather conditions, biodiversity loss, species extinction, food insecurity, and worsening health and poverty for millions of people worldwide. .
