Since natural resources are limited, if they are over exploited for short term gains, future generation will suffer heavily.
Reuse does not consume energy.
Sustainable management is a resource management technique which aims to conserve the resources, use them efficiently and avoid their misuse for individual Purpose such that they are conserved for future.
Reuse is better than recycle because:
(i) Reuse saves energy by using material again without any changes
(ii) Reuse prevents environmental pollution.
(iii) Reuse saves time as same material is used again.
