Hello Andrea!
In the first few lines, you repeat the phrase "the water" quite a few times. You can employ the possessive case (
its) in such instances.
The second paragraph has too many details which may not interest the adcom. You can sum it up in fewer sentences and merge it with the third paragraph.
Likewise, the fourth and fifth paragraphs contain some irrelevant details. Instead you should focus on the topics which are relevant to your selected major. For instance, you can elaborate on the experiences you had while you were an Amnesty International member.
I want to use my very adaptive skills to become part of new communities and help those communities flourish. In college I want to continue discovering nature and learn more about other cultures. I want to help countries like my home country, because I have seen the damage that there is in the world.
This is all very good, but it's not specific. Talk about something specific, like a career you want to pursue, or the kind of job you like, etc.
Good luck! I'm sure you are on a roll ;)
