The American Space Agency is continuing experiments that would make possible extended periods of space travel. One of these experiments is aimed at finding ways to grow food in space. Scientists at the Kennedy Space Center in the Southern state of Florida are doing these experiments. They are attempting to grow vegetables that could survive without sunlight and dirt. Their laboratory is a large circular container. Computers control the levels of light, heat, water, fertilizer, and gases in the laboratory’s atmosphere. The plants are grown in special devices that hold about 1 centimeter of liquid plant food. Plastic sheets cover the roots of the plants. The containers are designed to keep the plants from floating away in the weightless environment of space. Water is collected and reused. Bacteria and fungi help turn plant matter into simple sugars that could be added to the astronaut’s food or fed to fish.

Too bad, because this report card says a lot less about actual air quality than it does about the tactics and motives of the ALA.
The very fact that 60 percent of counties were giver an "F" seems to be alarmist. This is particularly true given that smog levels have been trending downward for several decades. According to the Environmental Protection Agency (EPA
