Travelling the world is a dream for many people，but do you want to make a difference while enjoying the world? 1
Volunteer travel is an act of taking a trip where all or part of the purpose of the trip is to do voluntary work. 2 During the trip，volunteer travellers often provide services like teaching，cooking，animal caring，and cultural activities. In exchange for their help，they may get free or cheap accommodations(住宿)，meals or classes.
Volunteer travel isn't a new way to explore the world. It first became popular in the 1960s. 3 However，as time goes by，more and more volunteer trips are taking place in the volunteers' home countries.
4 Volunteer travel allows you to give back to the communities you visit. Whether you're teaching English to children，cheering up sick kids，or working with wildlife，your efforts can make a real difference in the lives of others.
5 It's also a great way to explore new cultures，meet new people and open our minds to the world around us. By working alongside locals on community projects，you'll gain a deeper understanding of the places you visit and learn some valuable life skills.
