In the article, "Spuds or Duds," the author teaches us how genetic engineering is helpful and supports space exploration because it provides a food source for astronauts. The scientists have been doing tests and experiments on a potato spud that has been combined with many genotypes to take on the harsh conditions of Mars. The experiment has two purposes, to find out which vegetable can best cope to climate change and to identify a vegetable that can provide for astronauts. One scientist, Jan Krueze, believes that eventually growing potatoes on Mars is possible.

In the article, Newsela teaches us that as the use of GMOs in food is increasing many Americans are worried about the chemicals being put into their foods by big companies.  The use of GMOs in the United States is dramatically increasing and destroying our plants.  Chemicals such as glyphosate and other herbicides fight off pests but they aren't good for the plants.  If these big chemicals are destroying the plants are they actually okay to eat.  Many people want their food products labeled in fact, a New York Times poll found that 93% of people want GMOs labeled.  This proves that we need new laws about GMOs.
