Ex. 35 ⟹ Complete the text using the verbs given.

• Alter                                     • Exist                                           • Occur
• Boost                                   • Host                                           • Produce

Humans have ______ed different species for thousands of years through selection.

But genetic engineering, altering the genetic makeup of an organism, has only ______ed since the 1970s. The term "genetic engineering" was first  _____ed by Jack Williamson in his science fiction novel Dragon's Island, published in 1951.

One of the best-known applications of genetic engineering is agriculture. It can increase the growth rates and resistance to different diseases _____ed by pathogens and parasites. This is undoubtedly beneficial as it can ______ the production of food sources with the usage of fewer resources that would be required to _____ the world's growing populations. These modified crops would also reduce the usage of chemicals, such as fertilizers and pesticides, and therefore decrease the severity and frequency of the damages_______ed by chemical pollution.

Nevertheless, the issue ______s a lot of controversy. Ethical and safety concerns have been raised more than once around the use of genetically modified food. A major safety concern ______s to the human health implications of eating genetically modified food, in particular whether toxic or allergic reactions could ______. Ethical concerns also involve religious issues, corporate control of the food supply, intellectual property rights and the level of labeling _____ed on genetically modified products.
