can you help me? Thank you Good morning, everyone.The subject of my presentation is 3 ways to make the world a better place. First are plant trees. As the population explosion, air pollution of the earth is becoming more and more serious. A lot of trees are cut down are one of the reasons of air pollution. In order to control air pollution efficiently, we should plant millions of trees because trees can clean the air. Secondly, is trying to help others. Everyone needs help and everyone can help others. I think human beings live in a same plant, we need to help each other to make our society better. Finally, is equal. Now in the 21st century, there are still a lot of people are prejudiced, and i think all individuals should be equal. I hope every place in the world should not be hierarchical, but be equal. This concludes my presentation. Thank you for listening
