Answer 1

Answer:

1. Public transport is a system of transport, in contrast to private transport, for passengers by group travel systems available for use by the general public, typically managed on a schedule, operated on established routes, and that charge a posted fee for each trip.
2. Explanation: In fact, to assess the emissions of a type of transport we must first know its fuel consumption per km. This number must afterward be multiplied by a specific emission factor (that depends on the fuel used).
3. By moving people more efficiently, public transit produces significantly less air pollution per passenger mile than a standard car carrying a single driver. Buses emit 20% less carbon monoxide, 10% as much hydrocarbons, and 75% as much nitrogen oxides per passenger mile than an automobile with a single occupant
4. Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers
5. Atomic energy, solar energy, and energy from wind and bio fuels are just a few of the promising alternatives for a cleaner and greener future. Other relatively new sources of energy such as fuel cells, geothermal energy, and ocean energy are also being explored.
6. Energy conservation is the decision and practice of using less energy. Turning off the light when you leave the room, unplugging appliances when they're not in use and walking instead of driving are all examples of energy conservation.
7. Pros of CFLS
8. Longevity—With an average lifespan of approximately 10,000 to 15,000 hours, a CFL bulb lasts about ten times longer than an incandescent bulb—which means they need to be replaced less often, making them convenient for those hard-to-reach light fixtures and lamps.
9. Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes.
10. Solar Energy. Our beautiful bread and butter, solar energy. ... ₹Wind Energy. Another clean energy source, wind energy is technically another form of solar energy since the sun is partly responsible for all weather patterns on Earth. ...
11. Organic farming is an agricultural system which originated early in the 20th century in reaction to rapidly changing farming practices. Certified organic agriculture accounts for 70 million hectares globally, with over half of that total in Australia.
12. modern method of farming are not environmental friendly because of the following reasons : ... fertilizers are used in modern farming and that is harmful to the soil. 2. in modern farming pesticides are used which kill the bacteria that is useful for soil fertility.
13. The most commonly used biopesticides are living organisms, which are pathogenic for the pest of interest. These include biofungicides (Trichoderma), bioherbicides (Phytopthora) and bioinsecticides (Bacillus thuringiensis). There are few plant products also which can now be used as a major biopesticide source.
14. In agriculture, green manure is created by leaving uprooted or sown crop parts to wither on a field so that they serve as a mulch and soil amendment. The plants used for green manure are often cover crops grown primarily for this purpose.
15. Key Benefits
16. Farm Yard Manure is a valuable soil improver which enhances and restores a range of natural properties of the soil; Increases soil fertility. A natural source of available nitrogen. Adds humus and slow releasing nutrients to the soil.
