Question

Environmental degradation has been seen everywhere.' Explain any three values that can help to prevent environment degradation. 

Answer 1

Our environment is precious to us. We should not exploit the beauty of it in any way.
Three values that can help prevent environmental degradation are as follows:Responsible behaviour: We should always switch off the lights and fans when they are not in use.Being conscious about the environment: We should be conscious in what we are doing towards the environment. For example, we should encourage car pool and use public transport to control pollution and save fuel.Sustainable thinking: We should preserve and protect the resources so that all of them are not exploited by us and some are left for the future generation.
