In essence, humans are a new global geophysical force. Unlike previous geological epochs, where various geological and climate processes defined the time periods, the proposed Anthropecene period is named for the dominant influence humans and their activities are having on the environment. The impact of so many people on the planet has resulted in some scientists coining a new term to describe our time-the Anthropocene epoch. This is an understandable fear, and a quick look at the circumstantial evidence certainly shows that as our population has increased, the health of our environment has decreased. Many people worry that unchecked population growth will eventually cause an environmental catastrophe. waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases.consumption of resources such as land, food, water, air, fossil fuels and minerals.The impact of so many humans on the environment takes two major forms: Human population has seen exponential growth over the past few hundred years. Since then, continuing improvements in nutrition, medicine and technology have seen our population increase rapidly. It took until 1804 for us to reach 1 billion people. The United Nations estimates that the world population will reach 9.2 billion by 2050.įor most of our existence the human population has grown very slowly, kept in check by disease, climate fluctuations and other social factors. More than 7.3 billion individuals who, while busy consuming resources, are also producing vast quantities of waste, and our numbers continue to grow. That’s more than seven billion three hundred million bodies that need to be fed, clothed, kept warm and ideally, nurtured and educated. In 2015 the world population is more than 7.3 billion people. We are clever, resilient and adaptable―perhaps a little too adaptable. From our humble beginnings in small pockets of Africa, we have evolved over millennia to colonise almost every corner of our planet.
