Humans, like all other creatures, have apparently changed their environment, but their changes are generally more dramatic than those of other species. Some of these changes, such as the destruction of the world's rainforests, the provision of pasture for livestock, or the drying up of almost three-quarters of the Aral Sea, were once the world's fourth largest freshwater lake for irrigation, leading to changes in climate patterns, which in turn changed flora and fauna Species distribution, scientists are trying to understand the long-term impact of human activities on ecosystems, while environmentalists are dedicated to experts in various fields. Citizens of the United States and other countries are trying to reduce the impact of human activities on population growth in the natural world.
Human population growth may be regarded as the root cause of almost all world environmental problems, with more and more people each year Joining the world, with the increase of population, more pollution will be produced, more habitats will be destroyed, and more natural resources will be consumed. Even if new technological progress can halve the environmental impact on everyone, once the world population is doubled, the earth will not be better than before.
Good evening, ladies and gentlemen. I'm honored to be here to give a speech on punctuality. We all think that punctuality is very important in our daily life.
We must be punctual to establish habits for our students. We should be punctual in cl and abide by our promise. If we are late, the teacher must be angry and punish us.
Some teachers may not come in and shut you out. Otherwise, he will criticize you for facing the clroom or ask you to clean the clroom. Some people think that As long as a few minutes late, it doesn't matter.
We shouldn't be punished. I agree that it's impolite for teachers to punish them for being late, and we should respect our teachers. Once punished, we will never forget and correct the same mistakes.
Our lateness will affect the teacher's teaching mood and have a bad impression on you. So don't be late. Sometimes I'm late I'll say sorry for being late.
I'll try my best to avoid it. Everyone knows the meaning of being punctual. But how many people can say that it's not enough to know that I'm not late once.
So, thank you for your action.
