What do you need to design a poster for the debate? In the 20th century, the whole international community made unremitting efforts to ban biological weapons and made some progress. However, in the 2nd/kloc-0th century, the potential threat of biological weapons has greatly increased, and some countries and regions may continue to develop biological weapons. In addition, the rapid development of biotechnology has greatly increased the potential threat of biological weapons, and bioterrorism marked by the "anthrax incident" in the United States poses a real threat to international security.

With the development of economy, the acceleration of people's life rhythm and the improvement of living standards, the amount of plastics is increasing day by day. From 65438 to 0996, the consumption of plastic packaging in China reached 2.43 million tons, with an average annual growth rate of more than 20%, especially in the garbage of cities, main traffic arteries and tourist attractions. According to the survey, the annual output of domestic waste in Beijing has reached 3 million tons, of which waste plastics account for about 3%, with an annual growth rate of 48%. The content of plastic in garbage in coastal cities is higher, reaching 8- 10%. These waste plastics account for more than one third of the garbage volume, which greatly increases the difficulty and cost of garbage disposal. Because waste plastics are difficult to degrade for hundreds of years, if discarded in the natural environment, it will provide a hotbed for the survival and reproduction of mosquitoes, flies and bacteria; If buried underground, it is easy to pollute groundwater, hinder the growth of plant roots, destroy soil quality and affect crop harvest; If you burn with fire, it will produce a variety of toxic gases. "White pollution" has become a major public hazard to China's social environment, which has seriously hindered the sustainable development of China's economy and environment.

How many amazing changes have taken place in the world since mankind entered 2 1 century. While people are delighted with the rapid development of science and technology, they have also experienced better anxiety and even disasters. In addition to the panic caused by the development of high technology, especially biotechnology, war and disease seem to directly bring mankind to the door of hell.

At present, the annual consumption of disposable tableware in China is about10 billion, mainly foam plastic products, which should be banned.

To stop the production and sale of these disposable foamed plastic tableware, it is necessary to develop and produce its substitutes.

Articles and green disposable tableware came into being. Experts believe that the development of green disposable tableware

And production is becoming a new environmental protection industry in China.

Wang Zhixue and the managers of several production enterprises.

Wang Zhixue said: At present, the green disposable tableware developed and produced in China can be divided into paper according to the types of raw materials.

Pulp, rice husk, rice straw and starch. At present, there are hundreds of enterprises in China that produce paper disposable tableware.

The annual production capacity is about 3 billion.

The raw materials of paper tableware are seriously polluted in the production process, with high cost, high strength, water resistance and moisture resistance.

Gender difference

The development of science and technology has brought great changes to our lives. However, these changes are not all in the right direction.

Disadvantages: environmental pollution. This is the most direct and obvious disadvantage.

2. Species extinction is accelerating. This is caused by environmental pollution and human hunting. It also belongs to the disadvantages of scientific and technological development.

3. Personal safety is increasingly insecure. Now tens of thousands of crimes occur on average every day. Most of their criminal methods are related to the current new technology. Especially gun-related crimes, ordinary people can't prevent them. From the Second World War, we can already see that with the development of science and technology, the damage and losses caused by the current war are far from comparable. It may even lead to the fate of human extinction.

Human's physical quality is not as good as before. With the development of science and technology, the emergence of vehicles such as air cars, trains and planes has greatly changed human daily life. Human beings are no longer always dependent on their own legs, so the physical quality of human beings is not comparable to that in the past. In today's society, it is impossible for Xiang Yu to "pull out mountains and rivers". If this situation continues to develop, it may make people's limbs atrophy and make people appear.

5. All kinds of emerging germs appear constantly, and the lethality of many germs has far exceeded the destructive power of previous germs. This is because the rapid development of medical science and technology has accelerated the mutation of virus, so that the development speed of science and technology can not keep up with the mutation speed of virus. Maybe one day mankind will perish because of a great plague.

Hold a hero debate without success or failure, and write a poster in the name of the student union. Heroes are not judged by success or failure. Jing Ke is a hero, and Qin Shihuang is a hero. Jing Ke failed in stabbing Qin and was a hero of failure. Qin Shihuang unified the six countries and was a successful hero. They are all heroes. Jing Ke is a dead hero and Qin Shihuang is a living hero, but no one can avoid death.
