Explanation:
population is the most dangerous for environment
Answer:
The world population is growing by approximately 74 million people per year
.Population growth is not evenly distributed across the globe
.Scientists are yet to conclusively determine the human ‘carrying capacity’ of Earth
.Population is only one of many factors influencing the environment
.We have consumed more resources in the last 50 years than the whole of humanity before us
.The 20th century saw the biggest increase in the world’s population in human history.We humans are remarkable creatures. From our humble beginnings in small pockets of Africa, we have evolved over millennia to colonise almost every corner of our planet. We are clever, resilient and adaptable―perhaps a little too adaptable.
In 2015 the world population is more than 7.3 billion people. That’s more than seven billion three hundred million bodies that need to be fed, clothed, kept warm and ideally, nurtured and educated. More than 7.3 billion individuals who, while busy consuming resources, are also producing vast quantities of waste, and our numbers continue to grow. The United Nations estimates that the world population will reach 9.2 billion by 2050.
For most of our existence the human population has grown very slowly, kept in check by disease, climate fluctuations and other social factors. It took until 1804 for us to reach 1 billion people. Since then, continuing improvements in nutrition, medicine and technology have seen our population increase rapidly.It's no surprise that as the world population continues to grow, the limits of essential global resources such as potable water, fertile land, forests and fisheries are becoming more obvious. You don’t have to be a maths whizz to work out that, on the whole, more people use more resources and create more waste.
But how many people is too many? How many of us can Earth realistically support?
Influenced by the work of Thomas Malthus, 'carrying capacity' can be defined as the maximum population size an environment can sustain indefinitely.
Debate about the actual human carrying capacity of Earth dates back hundreds of years. The range of estimates is enormous, fluctuating from 500 million people to more than one trillion. Scientists disagree not only on the final number, but more importantly about the best and most accurate way of determining that number—hence the huge variability.While poverty and environmental degradation are closely interrelated, it is the unsustainable patterns of consumption and production, primarily in developed nations, that are of even greater concern.
It’s not often that those in developed countries stop and consider our own levels of consumption. For many, particularly in industrialised countries, the consumption of goods and resources is just a part of our lives and culture, promoted not only by advertisers but also by governments wanting to continually grow their economy. Culturally, it is considered a normal part of life to shop, buy and consume, to continually strive to own a bigger home or a faster car, all frequently promoted as signs of success. It may be fine to participate in consumer culture and to value material possessions, but in excess it is harming both the planet and our emotional wellbeing.
A BIGGER PIE: TECHNICAL INNOVATION
This theory looks to innovation and technology as Earth’s saviour, not only to extend the planet’s human carrying capacity, but to also improve the quality of life for each individual. Advances in food production technologies such as agriculture, water purification and genetic engineering may help to feed the masses, while moving away from fossil fuels to renewable power sources such as wind and solar will go some way to reducing climate change.
‘Economic decoupling’ refers to the ability of an economy to grow without corresponding increases in environmental pressure. In 2014 the United Nations Environment Programme (UNEP) released a report titled 'Decoupling 2', which explored the possibilities and opportunities of technology and innovation to accelerate decoupling, and an analysis of how far technical innovation can go.
Funding and research should be a high priority in these areas, but we must accept that technology can only do so much, and is only part of the solution.
