A holistic system of farming, which is primarily aimed at cultivating the land and raising crops in such a way, as to keep the soil alive and in good health in an eco-friendly pollution free environment.
Organic Farming
Assertion (A): Pollution affects the air we breathe, the water we drink and the soil in which we grow our crops.
Reason (R): A comprehensive set of preventive measures are required to check the growing menace of pollution.
Both A and R are true and R is the correct explanation of A.
Explanation — Pollution affects the air we breathe, the water we drink and the soil in which we grow our crops. Therefore, a comprehensive set of preventive measures are required to check the growing menace of pollution.
(i) The given picture depicts the scene of a Traffic Jam, indicating towards Vehicular Air Pollution. It can be reduced in the following ways:
(ii) The given picture shows industrial water pollution caused by untreated or poorly treated wastewater being discharged from a factory into a nearby water body. It can be reduced in the following ways:
(i) The given picture (i) shows solar panels, and they reduce energy consumption.
Solar panels use renewable solar energy to generate electricity. This reduces dependence on fossil fuels like coal, oil, and gas, which consume non-renewable resources and pollute the environment. Solar energy is clean, sustainable, and reduces both energy consumption and pollution.
(ii) The given picture (ii) shows people burning firewood. No, firewood does not reduce energy consumption, rather it substitutes one form of energy with another.
Firewood is burnt to produce heat, where chemical energy stored in wood is consumed to produce heat and light. Although it doesn't use electricity or fossil fuels directly, it still requires energy input (biomass) and therefore does not contribute to energy conservation.
'No Smoking Zone' is a area where people are restricted to smoke.
Under the Prohibition of Smoking in Public Places Rules 2008, smoking in public places was prohibited. A person caught smoking in public places or 'No Smoking Zone' has to pay a fine.
Fossil fuels refer to buried, combustible deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, and natural gas by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
Two fossil fuels are coal and petroleum.
Three measures to save energy are-
Organic farming is a holistic system of farming, which is primarily aimed at cultivating the land and raising crops in such a way, as to keep the soil alive and in good health by use of organic wastes and other biological materials along with the beneficial microbes to release nutrients to crops for increased sustainable production in an eco-friendly pollution free environment.
Vehicles cause air pollution in the following ways-
Two advantages of carpooling are-
In recent years, there has been an increasing trend for private vehicles. This has resulted in far more vehicles on the road leading to more vehicle emissions and thus more pollution.
If we have an efficient public transport, then people can be convinced to use the public transport instead of private vehicles. This, in turn, will contribute to a healthier environment by improving air quality and reducing oil consumption.
Passive smokers are those who do not smoke themselves, but unavoidably breath in second-hand tobacco smoke exhaled by the smokers at public places.
Smoking harms passive smokers as they have an increased chance of many health problems such as lung cancer, asthma, bronchitis and sudden infant death syndrome in children.
Two legal provisions meant to deter smoking are-
Two advantages of having a 'No Smoking Zone' are-
The measures which an individual can take to reduce consumption of energy and to create a cleaner environment are:
'Organic Farming' is so called because it is aimed at cultivating the land and raising crops in such a way, as to keep the soil alive and in good health by use of organic wastes and other biological materials along with beneficial microbes to release nutrients to crops for increased sustainable production in an eco-friendly pollution free environment.
It excludes the use of synthetic inputs such as fertilisers, pesticides, hormones and feed additives and rely upon crop rotations, crop residues, animal manures, off farm organic waste and biological system of nutrient mobilization and plant protection.
Two principles of Organic Farming are-
The main characteristics of Organic Farming are-
Organic farming is gaining popularity in recent times because people have become aware of their benefits. They contain no chemical pesticides and fertilizers and are grown naturally with manure or compost and only natural pesticides and insecticides are used.
Children are more susceptible than adults to diseases caused by chemical pesticide residues in food and so parents prefer to give them organic foods.
Another advantage is that organic foods do not contain growth hormones or antibiotic residues. Animals are often given growth hormones and antibiotics in animal feeds which are directly passed into animal foods like meat, poultry, fish, eggs, and dairy products and from foods to the consumers. In organic farming these practices are banned and animals feed outside in natural surroundings.
I think the following measures can be taken to check the menace of pollution before it is too late:
To implement preventive measures amidst a busy daily grind, individuals can:
