how can I prevent changes being made to my family tree by
other people, because I see that someone has been added
to my tree which is not correct
Among the most commonly asked questions on this forum relate to the issue you are raising.
There is a common misunderstanding that there is any concept of a "my family tree", when it comes to the format FamilySearch's "Family Tree" program adopts. It is a fully-editable database that relies on collaboration between contributors and, often, a lot of exasperating additional work when another user makes incorrect changes to the profiles of your family members.
As is commonly advised, to keep such changes to a minimum, add as much back-up as possible for the data you have inputted. Specifically, provide reason statements against individual items (e.g., why you are sure of a certain birth or death date) and enter notes in the Collaboration section detailing your research. Also, add sources that relate to the data inputted.
Unfortunately, there just is no stopping the more determined - perhaps uncooperative - user, who refuses to accept the facts / relationships you have added for your family members. Of course, always keep a back up of your work in a separate program. If you do this online, be sure to keep it within a program where others are unable to edit the details. Better still, keep it in one of the many programs you can install on your personal hardware, where nobody else can see / touch it.
Using Family Tree can be very frustrating at times, so it is your choice as to whether the perceived advantages (e.g. valuable contributions from others that you would not have found elsewhere) outweigh the disadvantages (especially in others being able to make unwanted changes to the data and relationships you believe to be correct).
Thank you very much for the answer and it is clear
