The lecturer discusses the drawbacks of genetic technology in agriculture. This contradicts the reading passage's claim that genetic technology provides many advantages.
First, the speaker argues that even though genetic engineering increased the amount of crop supply, it has happened mainly in wealth countries, not in the third worlds. This is because the world hunger is based on poor distribution of food caused by political issues. Studies have shown that there is already enough food supply to support the world population. This fact is in direct opposition to the reading passage's assertion that genetically engineered crops will produce more food, and accordingly the problem of hunger will released.
Second, according to the lecturer, when plants are resistant to the harmful chemicals through genetic technology, Those chemicals will be used more and more than before. This point is in contrast to the reading, which states that the use of dangerous chemicals which harm the environment will decrease as those chemicals eliminate insects and weeds without killing the genetically engineered crops.
The final point made in the lecture is that small farmers hardly benefit from advanced biotechnology. Since the high costs of the ceeds of genetically improved plants, companies with enough money take advantage of this high technology. Therefore, the economic gab between indivisuals and large companies is highly likely to increase. This refutes the reading passage's argument that small farmers will be able to enhance themsleves financially through the advanced genetic techniques. |
