These affect all of us, and

Taking these stepsdepends on whether people know about them and for fatigued people on whether they believe that mostother people a

Therefore, when there is good publicity for these steps, green fatiguewhich is limited anyway will disappear.Conclusion Green fatigue exists in the mind of a limited number of people. It is probably temporary. It can be changedwhen people know about the small positive green steps that they can take every day. The small number offatigued people will change when they see that everyone is doing something to benefit the environment.Guided writing
