I personally think that is quite meaningful because of some reasons

I have done my first community service for my class requirement.

which is :

Environmental Justice Opportunities: San Bruno Mountain

https://parks.smcgov.org/san-bruno-mountain-stewardship-saturday

I have only attended this event 9/22 9:45am-1:00pm

My profess needs me to write a 2 pages essay about the events, it should talk about my experience of it. For example, what was I thinking when I was cutting the grass, weeding, in order to maintain the environment for butterflies. what is the meaning of doing this kind of volunteer service. I personally think that is quite meaningful because of some reasons, but this kind of jobs is not my interest.
