Solution and Explanation

Step 1: Recall the core idea.
Sustainable development means growing the economy today without using up the resources that future generations will need.
Step 2: Resource and environmental protection.
Careful use of forests, water and minerals, along with practices like rainwater harvesting and afforestation, keeps resources from running out and keeps pollution in check.
Step 3: Shift toward renewable energy.
Using solar and wind power instead of only coal and petroleum cuts pollution while still meeting energy needs, for example through solar panel installations.
Step 4: Long-term payoff.
Balancing growth with conservation this way means development can keep going for a long time without damaging the environment or leaving future generations worse off.
Hence, sustainable development is essential because it protects resources and the environment while still allowing continued economic growth.
