ХІД УРОКУ

 

І. INTRODUCTION.

Підготовка до сприйняття іншомовного мовлення.

 

1. Організаційна частина уроку (привітання, оголошення теми та мети уроку)

T.: Good morning, everybody! Glad to see you here. Welcome to our English lesson. Pupils, please, check if you have your text-books, copy-books, handouts and pens on you desks. Anton, what date is it today? (Учень відповідає) Open your copy-books and write down today's date, class work.

 

1. Warming-Up.

We have been discussing global problems for several lessons already as the theme of the program is “It’s Your Planet”. I expect you know much about the threats our Earth is facing nowadays. What can kill our planet? You can answer all together.

 

Учні називають загрози життю на Землі.

Natural disasters Man-made disasters Asteroids Terrorism Technological advances

Вправа на поєднання.

 

T.: Look at these newspaper headlines and define the dangers.

 

2. Revision. Checking homework.

At home you were supposed to write short reports about the dangers you are worried about the most. I am eager to listen to your and check your homework.

 

Учні зачитують домашні твори

 

S1: Natural disasters are getting more destructive by the year. 

The number of people vulnerable to them has risen by 50,000 to 60,000 per decade since the early 1970s. At least half of their casualties are children.

Natural disasters like earthquakes, tornado, tsunami and floods happen more frequently nowadays. We like to think of ourselves as victims.

There are many reasons why they occur, but the main one is related to human activity on Earth which often has a negative impact on our environment.

There are many natural disasters which are dangerous for all of us. We should be careful and treat our planet better in order not to die with it.

 

S2: The matter is that some disasters are made by people. Natural and man-made disasters connect with each other.

Man-made disasters are the result of carelessness or human errors during technological and industrial use. The disasters are in the form of accidents, which occur all of a sudden and take a huge toll on life and property. Mostly such disasters cause injuries, diseases and casualties where they occur. Common examples of these disasters are train accidents, aero plane crashes, collapse of buildings, bridges, mines, tunnels, etc. Chemical spills and groundwater contamination can be caused by humans. Workplace fires are more common and can cause property damage and loss of life.

 

S3: Terrorism is considered to be the pressing problem of our time. Extremist groups use violence against both people and property.

At the beginning of the 21^st  century Israel, France, Germany, Great Britain, and Sweden suffered from the terrorism most of all. Terrorists attack military and civilian government buildings, international airports, large cities and famous landmarks. Cyber-terrorism involves attacks against computers and networks done to frighten or make a government or its people do what the terrorists require.

The danger of terrorism has changed our lives. Countries are now gathering information about terrorists on a more worldwide level. But in spite of all the efforts terrorism is still a serious global problem for humanity.

 

S4: I am afraid of stories about the end of life on Earth after a powerful asteroid attack. An asteroid striking our planet -- it's the stuff of science fiction. But it is also the stuff of science fact. There are craters on Earth (and the moon) that show us a long history of large objects hitting the planet.

Scientists have put a date to Armageddon. It will occur on 21 September 2030, when earth is in danger of being hit by an asteroid. It could strike our planet with a force 100 times greater than that released by the atom bomb that destroyed Hiroshima.

The new prediction is unlikely to be withdrawn, but not enough is known about the asteroid. Our planet is struck regularly by objects crashing down on us from outer space. There is always a chance it can happen.

 

II. MAIN PART.

FEEDING THE WORLD IN THE FUTURE

 

Today there are 7 billion people on earth. By the year of 2050 there maybe 12.5 billion. This is a lot of people to feed. Can farmers all over the world provide enough food for everyone? The answer is ‘yes, but...’

The western world’s answer is to use technology to produce the main foods more quickly. They have been very successful. Since 1961, it has produced nearly a quarter more food per person and it is 40% cheaper. Three foods, wheat, maize and rice, provide half of all the food we eat.

One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season they pick the best plants for the next season. It works very slowly. Since 1983 scientists have been able to change plants more quickly by changing their genetic material. Foods from plants grown in this way are called genetically modified foods, or GM foods.

By changing the genetic material of a plant, it is pos­sible to make new plants. They make plants which are strong against plant diseases. They can also help in human diseases: a kind of rice has been prepared, for example, which stops people becoming blind.

Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food. China grows thousands of hectares of GM foods and African countries are interested too.

GM plants are not natural. No one knows how good or bad they are. In one experiment, genetic material from snowdrops was put into a potato plant to help the plant fight disease. The potatoes were then fed to rats. The rats became ill. But were they ill because of the experiment? No one was sure.

There is another problem. The weather and climate can change. In Russia in 1972, the wheat failed during the winter that was very cold. In 1975, Indonesian farmers lost all their rice from a new disease. GM foods are not built to live through these kinds of changes.

Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, and then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050, we may think differently about them.

Transcript

 

We are all genetically modified organisms, all 7 billion of us and every other creature on earth produced by sexual reproduction. I point this out because “genetically modified” has become a loaded term that is misused to describe recombinant DNA biotechnology, one of the most important technological advances in the 10,000-year history of agriculture. Throw in bogus, Hollywood-inspired terms like Franken Foods, Killer Tomatoes, and Terminator Seeds, and you have the makings of one of the most groundless anti-science campaigns in the history of anti-science campaigns.

We  have  been  modifying  the  genetics  of  plants  and  animals  since  agriculture  and  the domestication of animals began. The anti-GMO activists counter, “Nature never moves DNA from  one  species  to  another;  therefore  GMOs  are  ‘unnatural’.”  Not  so.  Genes  have  been moving across species’ boundaries since life began. Bacteria routinely carry fragments of DNA from one species to another, and that DNA is sometimes incorporated into the genes of the host species.

This  random  movement  of  genetic  material  has  been  one  of  the  driving  forces  in  the development of species. The human genome, for example, has 70 percent of its genes in common with the sea urchin. Why wouldn’t we harness this naturally occurring phenomenon to improve the makeup of our food and fiber crops?

Today 18  million  farmers  in  28  countries  are  growing  genetically  modified  crops  on  448 million acres, 12 percent of the world’s farmland, or about the same area as all US cropland. It would be at least three times that if not for bans and restrictions in many countries -- bans and restrictions that are irrational, anti-science, and terribly harmful to the world’s poor.

Every credible science, health, and nutrition organization in the world says the genetically modified food available today is safe -- without reservation. This includes the World Health Organization, the European Commission, and the Society for Toxicology.

How many people know, for example, that the Durum Wheat used to make most of our pasta had  its  DNA  modified  by  exposing  seeds  to  high-level  gamma  radiation?  And  there  is  no labeling required!

But what about those supposedly evil seed companies like Monsanto? Aren’t they trying to “control the world’s food supply?”

First, let’s remember that these companies are not weapons manufacturers or drug cartels; they are trying to make better seeds for agriculture. Second, the seed companies don’t decide which seeds to plant; farmers make that decision. The fact is these companies have done massive good. Millions of people have nutritious food to eat thanks to their innovative work, work that has also reduced the use of pesticides.

Recently the first comprehensive study of genetically modified crop performance reported some surprising numbers. On average, GM crops increased yield by 22 percent, reduced pesticide use 37 percent, and increased farmer profits by 68 percent.

In addition, new varieties of GM crops offer nutritional benefits that are not present in the conventional varieties of crops. The best known of these is Golden Rice, a GM rice variety that, unlike conventional rice, has beta-carotene in the grain. The human body converts betacarotene into vitamin A. Without enough vitamin A, children go blind, and many die -- about 2 million every year in poor countries of Africa and Asia. In fact, lack of vitamin A is the biggest killer of children in the world today.

Invented 15 years ago, Golden Rice alone has the potential to end all vitamin A deficiency. Yet the anti-GMO movement is vehemently opposed to it just because it’s a GMO. As a result no country has approved Golden Rice for commercial farming. So, while children continue to go blind and die, the anti-GMO crowd celebrates a victory. And we’re supposed to be angry at Monsanto?

It’s time to put an end to the debate over the safety of genetically modified crops and foods. Today nearly all of our beer, wine, cheese and yogurt are made with GM yeast and culture. Most of our livestock are fed genetically modified corn and soybeans, and most of our prepared foods contain GM ingredients.

Here’s a simple solution:

People who want to believe there is something sinister or unhealthy about GM plants should either buy food that is labelled non-GM or pay more for so-called “organic” food. The rest of us, the ones who embrace science, can get on with healthy and productive lives.

4. Speaking.

A) Presentation of the project.

T: Let’s listen to Anton. He has done prepared the report about Monsanto company.

Учень презентує проект.

 

Monsanto is a global modern agriculture company. It develops products and tools to help farmers around the world grow crops while using energy, water, and land more efficiently.

The company was founded in 1901. Its headquarters is located in St. Louis, USA. There are more that 400 subdivisions in 66 countries around the world. More than 20 thousand people work for Monsanto.

In 1991 Monsanto signed a contract with Ukraine and started to supply plant protection products for farmers. The next year the company’s office was opened in Kyiv.

Monsanto “Ukraine” has been producing corn, canola and vegetable seeds as well as plant protection products in our country since 2008. In July 2017 news portal delo.ua/ reported that the company is going to open a plant producing seeds in the village of Pochuiky, Zhytomyr region. More than 200 people will be employed.

The company is developing new products and technologies that will help farmers to grow more food. They say their  products are among the most-tested in the world and their safety has been confirmed by experts.

B) Role-playing.

T: GM crops in our fields is our reality. Butt people can have different points of view about it. Choose the colour and speak for or against growing GM crops in Ukraine. Take your role into account.
