The following 5 inventions can 'save' Earth and humanity

In order to save the Earth as well as to ensure the future of all humanity against the ever-increasing negative impacts in both quantity and level, scientists around the world are constantly studying to make inventions. useful.

Our Earth is being "seriously poisoned" by numerous dangerous hazardous substances emitted by human activities, from smoke-filled cars to factories with tons of waste. .

In order to "save the Earth" as well as to ensure the future of all humanity against the ever-increasing negative impacts in both quantity and level, scientists around the world are constantly studying to bring out the Useful inventions.

1. The filter turns seawater into fresh water

Graphene filters turn seawater into fresh water.

Recently, researchers in the UK have successfully built a new filter with graphene material that is able to remove salt from seawater and turn into fresh water with high efficiency. With a modern desalination filter, this machine will be an effective solution for areas with frequent water shortages.

According to the UN forecast, by 2025, about 14% of the world's population will not have water for living because of climate change.

2. Mini planes for pollination

Pollination plays an extremely important role in nature as well as agricultural production activities, almost all human food used daily needs this process to fruition.

This shows that animals such as bees, butterflies . help people to pollinate is very important but according to a United Nations report, the number of individuals of these species is declining. and they are highly endangered.

Under these circumstances, researchers in Japan are conducting mini-aircraft experiments to replace insects, transporting pollen from one plant to another.

This type of mini plane has been successfully tested on a giant flower but in order to replace the bees' work, scientists need to improve this tool.

3. Biodegradable biological bullets

According to the US Department of Defense, hundreds of thousands of warheads and shells are discharged into the environment by the military each year. They contain toxic ingredients that endanger the soil and water resources and take hundreds of years to decompose.

Many areas in this country are heavily polluted by military vehicles.

Therefore, the US Department of Defense is developing a new type of biological bullet made from fast biodegradable material for use in training instead of previous powerful bullets.

They even proposed to include the seed of the tree into the bullet component to be able to produce food for animals after they fell to the ground.

4. A kind of "plastic" does not pollute the environment and is edible

An Indonesian businessman, Kevin Kumala, and his colleagues found a new plastic from cassava that could biodegrade after use.

They have produced raincoats, bags and food packaging from this plant resin. Even when you tear up bags made from this new plastic and put it in a cup of warm water, it is almost dissolved in water after just a minute and can be used as a drink.

5. A new type of aircraft only emits steam

This new type of aircraft is powered by hydrogen, oxygen, powered by electricity and emits only steam during use. They can carry up to 4 people including pilots.

This unique aircraft is part of the HY4 project of the German Aeronautics and Aeronautics Center (DLR) to build an environmentally friendly "aerial taxi" system. You can move from city to city with faster and more environmentally safe time.
