Solution
The effects of environmental degradation caused by human activities can be controlled by the following measures except
A
reclaiming the land
B
converting mining pits into fish ponds
C
resettling indigenous inhabitants
D
educating people
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
While resettling indigenous inhabitants might be a consequence of environmental degradation or development projects, it doesn't directly control or mitigate the effects of environmental degradation.
Reclaiming the land by restoring degraded lands can help revive ecosystems, Converting mining pits into fish ponds, can be a form of rehabilitation, making use of existing excavations, and educating people can also help in raising awareness and promoting sustainable practices which can significantly reduce environmental degradation.
Consequently, option C is the correct answer.
Education, land reclamation, and innovative reuse of areas like mining pits can all contribute to controlling environmental damage.
