There are a whole lot of amazing science facts that mankind today depend on to survive. Here are a few we would find extremely difficult to live without.
Clothing came into existence around 83,000 to 170,000 years ago as researchers assume. So for hundreds of thousands of years, our ancestors were running around naked. But clothes have literally saved our lives innumerable times since then.
We definitely started off like most animals — just finding a good place to hide. that probably even meant living in caves and nests in trees.By building shelters, humans were not as vulnerable to their environment and could survive harsher conditions.
- The Wheel:
The wheel is arguably the most important mechanical invention of all time. Almost all modern mechanical devices use the wheel – cars, buses, factory machines, toys, wristwatches, and more.
- Agricultural Crops:
A series of scientific and technical breakthroughs like the development of irrigation technologies, and the invention of crop rotation and fertilizers — that occurred over thousands of years, all started when humans learnt how to gather seeds, planted them, tend them, and harvested them.
The blade — and its iterations as an axe, a knife and so on – is a breakthrough that literally saves the lives of humans. New research has shown that stone tools like blade allow humans to eat better, wear better protective clothing and make for a good fight scene.
- Disposal System
The greatest scientific advancement in the last 150 years was sanitation. It was discovered that proper disposal of urine and feces could save lives. Sanitary prevention is certainly worth the cure of typhus, cholera, influenza and many other nasty germs that came with exposure to sewage.
- Water Purification
For centuries, even in developed countries, mysterious, periodic outbreaks of water-borne cholera regularly killed many thousands of people. The addition of chemical and filtration technologies have been developed to make our drinking water much safer.
The mastery of rapid oxidation by an unknown person in Africa was one of the most important developments that sustained the survival and spread of humanity, according to a member of an Israeli archaeological team that found the earliest evidence of human ability to make and control fire at will.
The use of penicillin and other antibiotics has led to reductions in mortality rate from certain infections like syphilis, HIV, cancer etc. Interestingly though, antibiotics can’t claim all the credit when it comes to decreased mortality rates in common bacterial diseases.
- Food Preservation:
The cans of packaged food in your refrigerator might seem like a humble advance in civilization. The ability to preserve foodstuffs for long periods without refrigeration enables human beings to survive natural and man-made disasters which disrupt our electrical supply and make it difficult to obtain supplies of fresh food.
