The article asserts that there is a big problem with cheatgrass, an invasive non-native plant from Europe and Asia which dwells in North America and threats the native plant species and even affects negatively the native animal habitat. It propses three methods to fight against cheatgrass. On the other hand, the professor mentions that none of those methods are likely to control the cheatgrass propagation well. First, the reading states that encouraging the cattles to eat cheatgrass will be an effective way to eradicate cheatgrass from the North America fields. Conversely, the lecturer rebuts this opinion by explaining that cattles prefer to eat native grass and unfortunately they eat native grass completely first and then they eat partially cheatgrass. This method will provide cheatgrass with more space and resources withoput a rival through which it could propagate enormousely and cover all fields. Therefore, he directly reject this idea. Second, the writer suggests that by controled burning fields, cheatgrass, which is a flammable plant, they would wipe out from the field. Controversially, the lecturer mentions that cheatgrass produces myriad seeds, which they will germinate years afterward. The seeds and palnts on the surface may burn but the underground seeds will be remained intact which are able to produce new progenies over the next years, the professor explains. With this justification this solution does not hold water. Thrid, the author avers that introducing a fungal parasite can kill the cheatgrass and will clear up the fields from this invasive unwanted gest. However, the speaker points out the cheatgrass and this fungus have been living together in Asia and Europe for thousands years; as a result, cheatgrass has developed resistance to cheatgrass. Indeed, this parasite is able to kill only the sick cheatgrass and the healthy grass is in a safe place. Consequently, this method won' taddress this problem.
