3 inventions that could save Earth

In today’s world, everyone is so caught up in using technology, that they don’t have time to think about the environment; however, as CNN reports, some inventors are trying to use technology to create things to help improve our planet and lives. Here are three inventions that could “save the planet.”

One of the creative inventions that could possibly save our planet, already developed by researchers in the United Kingdom, is a high-tech sieve that could make our oceans drinkable. This sieve (a utensil of wire or plastic mesh that’s held in a frame, used for straining solids from liquids) is made out of graphene and could be able to filter out the salt using less energy. This invention could provide us with safe, clean, fresh, drinkable water, which has been proven to be a rare resource in foreign countries around the world. The United Nations has predicted that in less than a decade about 14% of people around the world will not have access to clean water where they live.

Everyday things you eat and drink rely on pollination, which allows plants to reproduce; examples include apples, chocolate, coffee, and various fruits and vegetables. One invention created by researchers in Japan is a flying drone that will pollinate plants. About 75 percent of our world’s crops are produced with the assistance of pollinators like bees and butterflies. According to a U.N. report, “these insect pollinators belong to a group that’s facing extinction.” This drone was recently able to pollinate a larger flower, but it’s still in need of a lot more work before the machines can carry out the duty of the pollinators.

The protection of our environment can seem to not be an important priority to the U.S. military, but in 2017 this seems to be changing. According to CNN, “The U.S. Army asked for proposals for biodegradable ammunition to replace the existing rounds it uses during training exercises.” The current bullet casings that are ejected from a weapon after it’s been fired are believed to take centuries to biodegrade, according to the Pentagon. The U.S. Environment Protection Agency says that this has caused military facilities to make up a majority of the country’s most polluted sites. The U.S. Department of Defense is requesting for this new ammunition, which contains seeds, to produce food for animals. They say that “this effort will make use of seeds to grow environmentally friendly plants that remove soil contaminants and consume the biodegradable components developed under this project.”
