Kinds of Unusual Food to be Served in the Future ~ Kwentology

What will we be eating for dinner? In the next 50 years, another two to three billion people will be living—and eating—on Earth. With so many mouths to feed, scientists are looking for ways to guarantee there will be enough food to go around. This may include developing super crops that resist disease, insects, and weather extremes, so that they yield bigger harvests. Eating readily available sources of protein, such as insects and algae, simple, one-cell plants, is another suggestion.

But probably the most unusual idea of what will be on our table years from now is meat grown in laboratories. Why would scientists want to do that? Raising livestock takes up a lot of land. The animals consume huge amounts of plants and put out greenhouse gases that are bad for the environment.

When cows belch and pass gas, they give off methane, a greenhouse gas that traps heat in the atmosphere and has been linked to global warming. One adult cow can produce up to 400 pounds a year. Worldwide, cows and other cud-chewing animals produce 80 million metric tons of the gas.

The first meat successfully grown in a lab came from goldfish cells. NASA conducted the experiments in 2000, hoping to provide astronauts on long space trips with fresh meat. Nine years later, Dutch scientists produced pork from the cells of a pig.

Although it is technically possible to make test-tube meat, scientists are not able to produce it in large amounts. Plus it takes about one million dollars to produce 8 ounces of test-tube beef. (That's one pricey steak!) Until scientists figure out how to make it cheaper and quicker, test-tube meat will only be food for thought.

Carrots, radishes, and lettuce grown without soil? In the future, that might be how most vegetables are raised. It's all thanks to hydroponics—a way to grow crops in water without a speck of soil. As Earth's population skyrockets and farming land declines, hydroponics will provide farmers with another choice. Crops can be thrive in underground vaults, on rooftops, greenhouses, and in buildings designed for this space-saving farming method.
