Hello guys! Tomorrow is our free talking and all of my students will have the same topic. Our topic will be about "THE WORLD'S BIGGEST PROBLEM IN FUTURE TIME". I just want to ask some opinions about this for me to use some in my classes. All opinions will be highly appreciated and will be very useful. I'm looing forward to reading some responses. Thank you in advance. :)
