it is understandable, but could be phrased better. is this a letter to someone? or what is the porous? Irena Jaros founder of the Łódź Foodbank, has been involved in charity work for many years. Involved in numer of initiatives for children:( these seem out of place> „St. Nicholas’ Ambulance”, „We share what we have”, „Food fundraising”. maybe site where they are taken from?) She also organizes summer camps for kids. 1. how long have you been helping children? starting 1991, responding to Jacek Kuroń’s appeal “Let’s give summer to children”, I organised camps for young kids from disadvantaged families. Since then every summer we organize trips for children who wouldn't have seen the sea or lakes. Of course we owe a lot to volunteers. ( most believe that Volunteers are part of a thing not separate, so this phrasing gives credit to them with out separating them from the organization)

I see nothing wrong with this. As an English speaker, I understand it perfectly. Good job!

If you are writing in English, you should write your quotes in English style: "St. Nicholas’ Ambulance” - otherwise it looks strange and foreign. 'numer' - did you mean a number? You should also prefix that sentence with 'She has been...' I appreciate that this is probably only an excerpt, but even then it would be unusual to number questions...
