I see that in 2050

　　Fellow students, Distinguished guests, Mr Chairman, Honorable Judges I'm very glad to stand here and give you aspeech. today my topic is “The Year 2050 as I see it”。
　　I see that in 2050. Technology is more advanced, and the world is sustainable.
　　Perhaps the world will use solar energy, water conservancy and other power generation, which will mark the end of the oil era. Cars could be vastly safer, smarter, and cleaner. In the future, there will be no one to drive the car. traffic will be more secure, reducing the traffic accident. Still have a large area of garden. Technology to prevent disease can also be improved, design a vaccine to prevent the spread of AIDS and malaria.
　　Everything has two sides, so there are still some big problems in 2050. For example, a large population is a serious problem. At present, the world's population is about 7 billion. The United Nations is expected to reach 9 billion 600 million by 2050, a 30% increase. The world will become very crowded. More serious environmental pollution, followed by climate change and other natural wildlife will be extinct, large areas of coastal areas will be submerged. Natural wild animals and plants will be extinct, and large areas of coastal areas will be submerged. Now what we can do is to do our best to protect the earth and to create a bright future for all mankind!
　　Thank you very much for your attention.
