Explanation for above question

• Sustainable use of resources means that we use the resources in such a way that meets the demands of the
present without compromising the ability of future generations to achieve their own requirements.
• The following measures need to be taken to avoid over-exploitation of resources:
o Cultivation of land taking adequate care of soil fertility.
o Development of irrigation facilities with proper water management. Use of water-saving devices such
as traditional conservation methods and roof-top-water harvesting should be used.
o Use of bio-fertilisers and bio-pesticides in order to have a biological balance. Hence, option 1 is
correct.
o Judicious use of underground water to avoid steep fall in underground water level.
o Use of traditional seeds instead of the high yielding hybrid varieties to avoid spread of diseases
capable of wiping out the entire crops it happened with the Irish potato crop in 1985 and Bengal rice
famines in 1942. Hence, option 2 not is correct.
o Avoiding the use of non-degradable material like plastic to prevent problems of waste
management. Hence, option 3 is correct.
