So happy to participate in this Contest, below are my top 5 inventions that have been beneficial for humans and has made a big change.

Contraceptives;

Condoms came into use in the 18th century, while the earliest oral contraceptive "the pill" was invented in the late 1930s by a chemist named Russell Marker.

Contraceptives has saved many families from having babies when they didn't plan for it.

Wheel;

before wheel came into existence, transportation of both food and humans was very difficult.

"Evidence indicates wheel were created to serve as potter's wheels around 3500 B.C. in Mesopotamia—300 years before someone figured out to use them for chariots. The ancient Greeks invented Western philosophy…and the wheelbarrow

And today our foods are been transported through buses,cars, wheelbarrows, trucks all are made up with wheel.

Me personally can go to work because there is buses with wheel, transportation makes life easier and comfortable.

Wheel also made it possible for the disabled to move around

Penicillin;

Before penicillin was found bacteria 🦠🦠🦠 infections kill some many people,the rate of children's death was at the high side.

"In 1928, the Scottish scientist Alexander Fleming noticed a bacteria-filled Petri dish in his laboratory with its lid accidentally ajar. The sample had become contaminated with a mold, and everywhere the mold was, the bacteria was dead. That antibiotic mold turned out to be the fungus Penicillium, and over the next two decades, chemists purified it and developed the drug Penicillin, which fights a huge number of bacterial infections in humans without harming the humans themselves.

Penicillin has proving to be a good drugs that cures so many bacteria infections for so many years,like gonorrhea,candida infection and many other infections.

I as a medical personnel has seen the effects of this invention by scientist Alexander fleming.

Radio;

It has been beneficial, personally back in those days when not everyone had access to television,in the evening we will bring out our radio outside and be looking for stations,my father will be carrying the radio up and down to search for signal and we will be warming for dancing.

paper;

Paper was invented about 100 BC in China, paper has been indispensible in allowing us to write down and share our ideas.
