Our population today the population is in the billions and is expected to go much higher in the next few years. The population used to be somewhere in the millions but then there was the Industrial Age. Amazing breakthroughs in medical science started happening; cars came to roads and trains moved important goods. Then the amount of people on earth sky rocketed to immense numbers. That is why the population is very massive; though because of our great numbers the planet Earth’s resources are steadily decreasing; this can have catastrophic damage to the planet. Since we can’t stop population growth what we can do is save water; take more showers and drive cars less.
