1.- What do you think about the following statements?
Write T –F and support your answers.
a) There will be shortage of food in the future.
b) Seed can be genetically modified.
c) All genetically modified crops are resistant to pesticides nowadays.
d) Scientists can develop techniques to increase crops yields.
2. - Read the following article from Discovery Channel and answer
a) Define genes.
b) How do scientists modifify genes?
c) What are the advantages of engineering crops?
Scientists can transplant genes from one organism into the cells of another organism. Genes
are what give organisms specific features. Using precise methods, scientists can engineer
crops so that they grow in a wider range of conditions. They can also make plants resistant
to herbicides and pesticides or even increase crop yields. These new plants could, in theory,
grow in regions that traditionally have trouble supporting crops...

Why might agricultural biotechnology fail to solve world hunger?
Answered by Meredith Bower and Discovery Channel
Among the tools used by today's farmers is agricultural biotechnology. As crucial to their operations as tractors and
trucks, biotechnology is allowing many farmers to cultivate healthier, heartier plants and animals. In addition to
improved quality, it also results in greater production and more affordable food. Scientists, looking toward the future,
are engineering plants that produce more, last longer, are more nutritious and even help fight disease. Given the
benefits of agricultural biotechnology, it's logical to think it could be a solution to the problem of world hunger.
The Food and Agriculture Organization of the United Nations has projected that by 2050 the world's population will
reach 9 billion. In order to end the current hunger crisis and feed the growing population, food production will have
to increase by about 70 percent in the years between 2009 and 2050 [source: FAO]. Climate change, decreased
numbers of farmers and limited natural resources -- including basic resources like land and water -- add to the
scope of the problem. Essentially, fewer people must grow more food on less land.
Is agricultural biotechnology a solution? Proponents believe it can be, and some use "golden rice" as an example.
Developed by the Swiss scientists in 1999, the grain is high in vitamin A and iron. The enriched rice can feed the
hungry and lower the incidence of anemia, and at the same time it can help eradicate the blindness that comes with
vitamin A deficiency. In developing nations, where rice is a staple, golden rice has the potential to save millions of
lives [source: Bio]. Yet, despite the benefits of preventing starvation and malnutrition, golden rice has faced bans in
the European Union and in much of Africa. Why? It is a genetically modified organism (GMO), and GMOs are
typically prohibited in the EU [source: Simmons].
If the problem of world hunger is to be solved, countries must weigh the benefits and risks of agricultural
biotechnology, as it deeply affects humankind's ability to provide safe food for all. Furthermore, we must remember
that, whatever the appeal of any one particular agricultural practice, we should always work to help provide
consumers the right to choose how their food is grown.
5. - After reading the article, indicate if each statement is true or false.
a) _________She says that Agricultural biotechnology is the only solution to the
problem of world hunger.
b) _________She continues to add that more people must grow more food in more
land.
c) _________In developing nation, where rice is stable rice has some bans in the
European and in much of Africa.
d) _________Countries don´t have to consider the benefits and risks of agricultural
biotechnology as it deeply affects humankind‘s ability to provide food for everyone.
e) ________ She argues that, we should try to provide consumers the right to choose
the food however it is grown.
4. 6. - Working with Modal verbs.
Put the following statements in order of certainty.
_____Agricultural biotechnology might fail to solve the world hunger
_____Given the benefits of agricultural biotechnology, it is logical to think it could be a
solution to the problem of world hunger.
_____Food production will have to increase about 70% in the years between the 2009
and 2050.

regulation? Discuss and then let’s see what Ellen has to say.
2. - As you read, try to answer the following questions.
a) What are the advantages of improving crops resistant to pesticides or viruses?
b) Why some people avoid eating genetically modified foods?
c) What type of regulations does The United States have?

f) Is it an easy process? Why or why not?
g) What is the role of the Congress in the regulation of bioengineered foods?
How long does it take for genetically modified crops to hit the
market?
Answered by Ellen Stockstill and Discovery Channel
Genetically modified crops, also known as GM or GMOs, are crops whose DNA
structure has been altered. Scientists have modified the genetic makeup of some
crops to make them more resistant to pesticides or viruses. By improving crops'
resistance, developers hoped that farmers could produce more crops at a lower
cost. Genetically modified crops were introduced commercially in 1996 and have
become increasingly more common since. According to the USDA, in 2004, 46
percent of corn, 76 percent of cotton, and 85 percent of soybeans were
biotechnology plantings [source: USDA].
Some people avoid eating genetically modified foods, thinking that they pose a
risk to the environment and to human health. One reason why people are
concerned is that there has been very little research done on possible long-term
effects on humans. Some countries have strict regulations on genetically modified
foods. The United States' Food and Drug Administration requires that a food be
labeled as genetically modified only if its nutritional content changes in the
modification process or if the process introduces a common allergen.
The FDA calls genetically modified crops bioengineered foods, and the agency
determines what food can be sold in our supermarkets. In order to put a new
genetically modified food on the market, the developer must enter into a
consultation process with the FDA during which the developer must prove that
the new product adheres to the Food, Drug, and Cosmetic Act. To do this, the
developer must submit a summary of the new food's safety and nutritional
assessment and meet with FDA scientists, if necessary, to discuss the information
presented or supporting the assessment. This consultation process can be
AFTER READING
Are genetically modified food labeled in Argentina? Support process varies,
precarious, lengthy and painstaking. Although the length of thisyour answers. it
can take years. Some foods can make it far into the process and then be turned
down. Recently, Congress voted to stop the FDA from approving genetically
modified salmon for human consumption. The salmon would have been the first
genetically modified animal sold for food.
6. 3. - Work in pairs and look for information about Regulations in Argentina about
this issue at home.
- Surf the internet.
- Go to the supermarkets and see if the products have any type of label with specific
information about genetically modified foods.

WHAT DIFFERENT PEOPLE SAY…
3. - As you read the next three texts, complete the following chart about
genetically modified food.
FOR AGAINST
Put aside prejudices
Paul Collier is a professor of economics at Oxford University and the director of the Center for the
Study of African Economies. He is the author of “The Bottom Billion: Why the Poorest Countries Are
Failing and What Can Be Done About It.”
The debate over genetically modified crops and food has been contaminated by political and aesthetic
prejudices: hostility to U.S. corporations, fear of big science and romanticism about local, organic
production.
Refusing genetic modification makes a difficult problem more complex.
Food supply is too important to be the plaything of these prejudices. If there is not enough food we
know who will go hungry.
Genetic modification is analogous to nuclear power: nobody loves it, but climate change has made its
adoption imperative. As Africa’s climate deteriorates, it will need to accelerate crop adaptation. As
population grows it will need to raise yields. Genetic modification offers both faster crop adaptation and
a biological, rather than chemical, approach to yield increases.

The Failure of Gene-Altered Crops
Vandana Shiva is the founder of Navdanya, the movement of 500,000 seed keepers and organic farmers
in India. She is author of numerous books, including “The Violence of the Green Revolution” and “Soil,
Not Oil.”
Food security over the next two decades will have to be built on ecological security and climate
resilience. We need the real green revolution, not a second “Green Revolution” based on genetic
engineering.
We need biodiversity intensification that works with nature’s nutrient and water cycles, not against them.
Genetic engineering has not increased yields. Recent research by Doug Gurian-Sherman of the Union of
Concerned Scientists published as a study “Failure to Yield” has shown that in a nearly 20 year record,
genetically engineered crops have not increased yields. The study did not find significantly increased
yields from crops engineered for herbicide tolerance or crops engineered to be insect-resistant.
The International Assessment of Agricultural Science and Technology for Development carried out by
400 scientists over four years has also concluded that genetic engineering does not hold much promise.
Instead, small farms based on principles of agri-ecology and sustainability produce more food.
That is why I am so disappointed that the Gates Foundation in its global development program is
supporting the use of genetically modified crops in Africa.
10. Green revolution technologies and strategies, reliant on monoculture and chemical fertilizers and
pesticides, have destroyed biodiversity, which has in many places led to a decline in nutrition output per
acre.
As I have shown in my book “Soil, Not Oil,” industrial systems of food production are also a major
contributor to greenhouse gas emissions and climate change. Industrial monocultures are more
vulnerable to climate change since they reduce soil organic matter which is vital for moisture
conservation and resilience to draught.
The claim by the genetic engineering industry that without genetically modified food we cannot respond
to climate change is simply false. Climate resilient traits in crops have been evolved by farmers over
centuries. In the community seed banks that I have helped create through the Navdanya movement, we
have seeds for drought resistance, flood resistance and salt tolerance. This is the biological capital for
the real green revolution.
The gene giants are now pirating and patenting the collective and cumulative innovation of Third World
farmers. Patent monopolies on seed cannot create food security. They can only push small farmers in
debt.
The green revolution that we are building through Navdanya is based on conserving biodiversity and
conserving water while increasing food production per acre. What we need is biodiversity
intensification, not chemical intensification. What we need is to work with nature’s nutrient cycles and
hydrological cycle, not against them. It is time to put small farmers, especially women, at the heart of
this process.
11. How could agricultural biotechnology help people who
need food?
Answered by Discovery Channel
Planet Green
Besides adhering to organic principles, there are six principles practitioners of biodynamic agriculture
follow. Plant diversity, planting a variety of plants and mixing crops helps replace nutrients in the soil.
Crop rotation and raising an assortment of animals encourages healthy soil and fewer parasites, pests
and weeds. Composting creates healthy soil, humus and nitrogen to support healthy crops. Nine
homeopathic solutions from extracts of animal manure, plants and minerals are sprayed to treat
compost, soil and plants. And life force acknowledges the importance of moon phases as well as
celestial and seasonal cycles' impact on the farm.

12. IT IS TIME TO DEBATE
How many people don't have enough food to be healthy?
Answered by Jessika Toothman and Planet Green

Contributor
Jessika Toothman
Malnourishment is a serious threat to the health and wellbeing of many people across the planet. Also
known as undernourishment, it can lead to both long term and short term health issues, and is often a
self-sustaining cycle closely linked to poverty. The Food and Agriculture Organization estimated that
there were close to a billion people -- 925 million -- who went undernourished at some point in 2010.
Two thirds of those people can be found in just seven countries: China, India, Ethiopia, Bangladesh,
Indonesia, Pakistan and the Democratic Republic of Congo. In terms of how many people in a region are
undernourished compared to the general population, sub-Saharan Africa ranks first. About 30 percent of
the people who live there do not get enough food to be healthy.
According to the United Nations, more than 1 billion people go without enough food to be healthy. This
has prompted the U.N. to declare world hunger as the worst health risk worldwide. While the global
production of food might be enough to meet the needs of the globe's population, complicated issues such
as transportation, politics and economics can prevent those in need from receiving what is otherwise
excess food.
