Introduction to Top 10 Scientific Breakthroughs We Literally Couldn't Live Without
When you stop to think about it, humans are pretty amazing animals. Not only have we managed to stick around in various forms for millions of years, but we've grown into a population of more than 7 billion, scattered virtually all over the planet. And we've done it despite the fact that, compared with much of the rest of the animal kingdom, we're fairly fragile creatures. We're not particularly strong; we lack a tough hide or fur to protect us from the elements; we don't do very well without a regular supply of food and water; and we're vulnerable to a lot of infectious diseases.
So what is it that has enabled us to thrive -- to the point where, for the most part, we don't spend every waking moment worrying about whether we'll live to see another day? Our saving grace, perhaps, is our highly developed brain and its ability to experiment with, dream up and collaborate on ingenious solutions to life-threatening challenges. There are a multitude of inventions that modern humans have come to depend on to sustain their existence. But here are a few we would find it extremely difficult to live without.
