 Use the following information to answer the next four questions.

Miracle Rice
Rice is staple food in Asia. In the 1950s, Asia faced food shortage and an impending famine. If you have relatives that lived in Asia during the ’50s and ’60s, they may tell you that due to the rice shortage, many starved and those who were lucky had to supplement their diet with other crops, such as barley.

In 1962, an organization focused on research and development of rice called International Rice Research Institute (IRRI) developed a high-yielding variety of rice by crossing the two types of rice from Indonesia and China. The result was ground breaking. The new variety called IR8 (India Rice 8) increased its yield as much as 10 times the traditional variety of rice.

By the early 1970s, many rice farmers in India, the Philippines, and Vietnam switched to cultivating IR8 rice, making these countries into major rice exporters, preventing a mass famine in Asia, and saving millions of lives.

#16. Is the IR8 rice variety considered a genetically modified organism (GMO)? Why or Why not? Support your answer with research. (2 marks)
i can answer the rest on my own but i want to say that the IR8 rice is considered a GMO because biotechnology helped to save the lives of those who were dying out of food shortage in Asia.

that is the link i used to help me answer this question but i don't know if my answer is good enough.

these are the other questions, i think i can answer these on my own but i just need some guidance for #16.

#17. Although IR8 was widely cultivated in Asia in the ’70s, it is no longer produced in the 21st century. Identify one problems associated with mass cultivation of IR8 and explain its environmental impact. (2 marks)
#18.Is it possible to consume non-GMO wheat, corn, canola, soy, sugar, or papaya in Canada? Choose one of the listed food items and discuss the impact of biotechnological research on its current availability in our country. (2 marks)
#19.In many major Canadian cities, a GMO-free, organic diet is becoming more popular, as can be seen in most major grocery chains. Should we advocate for GMO-free lifestyle? Using 150 words or less, explain your position. (4 marks) ( i have attached an image for the rubric i was given for #19).

According to the World Health Organization, "Genetically modified organisms (GMOs) can be defined as organisms (i.e. plants, animals or microorganisms) in which the genetic material (DNA) has been altered in a way that does not occur naturally by mating and/or natural recombination."

Given that two strains were "crossed", the genes weren't technically tempered with, so arguably what happened is natural.

There's always the possibility that this hybrid crop may be toxic to non-target organisms. Additionally, biodiversity, while it is critical in all ecosystems and to the sustainability of all species, is put at risk by hybrid organisms such as this one. When these crops are planted, many heritage seeds are no longer used. One of the real reasons it was stopped was because farmers needed to match the exact conditions that were suited for it to grow. However, it did not fit most rice-growing situations, which involve heavy monsoons or deep flooding. The impact here would be diverting fresh water ways just to produce a yield.

#18.Is it possible to consume non-GMO wheat, corn, canola, soy, sugar, or papaya in Canada? Choose one of the listed food items and discuss the impact of biotechnological research on its current availability in our country. (2 marks)

There are four genetically modified crops grown in Canada: GM corn, canola, soy and white sugar beet. GM tomatoes, GM rice and GM wheat are not on the market anywhere in the world. Without providing any valid sources, I can say that GM products are important -- they lessen our dependence on chemical herbicides and insecticides (most of which are water soluble and can causes issues higher up in the food chain), they're less expensive to cultivate and purchase, and most often produce a better yield for the farmer (less work, more product).

#19.In many major Canadian cities, a GMO-free, organic diet is becoming more popular, as can be seen in most major grocery chains. Should we advocate for GMO-free lifestyle? Using 150 words or less, explain your position. (4 marks) ( i have attached an image for the rubric i was given for #19).

No, a GMO-free lifestyle would be very difficult and expensive to maintain. Firstly, the Canadian government doesn't collect reliable data on crops grown in the country, therefore hasn't technically established mandatory labeling of GM foods. Given that nearly all corn produced in Canada is genetically modified to some extent, and that most foods contain corn, it would be hard to track which of the ingredients is coming from Canada and which is imported. In order to live a non-GMO lifestyle, it would have to start at the top. The government would have to tracking the area of all GM crops and non-GM crops across Canada, tracking organic crop area (which is doesn't have guidelines for, currently), and monitoring which GM crops, GM traits and foods are on the market and providing Canadians with a clear list of the GM food crops and traits on the market.
