Megacities in the twenty-first century
The megacity infographics show the current numbers of the city inhabitants worldwide. Out of 30 megacities, 17 are Asians, 5 Europeans, 6 Americans (both south and north) and finally 2 Africans. At the beginning of the twentieth century, 10% of the world’s population lived in the city’s, a century later more than 50%. The estimated number of city residents in 2025 could arrive at more than 5 billion, of which, two-thirds of them less-developed countries. The challenges for fairness, developments on a social as well individual are enormous. Water supply, food, waste, pollution, traffic is just a few elements of these demands. New industrial eras merge with suburbs around cities and create human-made environments and landscape. The difference between a city and nature hardly exist. The city has become a metropolis with urban centres, industrial eras, airports, villages, ports, constructed woods and beaches.
We are 24-hour consumers
The generation after us have several people growing up in megacities will never experience real nature. Their experiences will be limited to organized parks, watching animals at Zoo and TV programs. How will this affect their relationship, care and understanding necessity of forest protection, rivers, and animals? What about the expanding consumer culture that has infiltrated us beyond any scale? Will the lack of experience and relationship with nature reduce the resistance of shopping patterns? In nearly all areas of our lives, shopping is implanted, devices such as smartphones, the Internet, club cards; telephone sales have made us a “24-hour consumer.” We are, in fact, living in a global shopping-mall without knowing it. Welcome to the twenty-first century western society.
The highly sugar-addicted consumers high on shopping hardly realize how most people live; 800 million people around the world are living with no access to clean water. Diarrheal disease caused by unsafe water is the second-leading killer of children worldwide (charity: water). The worlds are by no means in balance. Wealth and individual well-being recognized by human rights and figures from the UN confirm the differences and inequity already in 1987.
Sustainable development basic values
The sustainable development benefits more full acceptance after the World Commission on Environment, and Development (WCED) published its report “our common future” in 1987 (Also known as the Brundtland report (also known as “the Brundtland Report”) in 1987.
Ever since the report was released, it’s been the benchmark for all future discussions on sustainable development. “Our common future” discuss the threat to humanity by stating: “The Earth is one, but the world is not. We all depend on one biosphere for sustaining our lives. However, each community, each country, strives for survival and prosperity with little regard for its impacts on others. Some consume the Earth’s resources at a rate that would leave little for future generations. Others, many more in a number, consume far too little and live with the prospects of hunger, poverty, disease, and early death.” WCED, 1987. With a scenario, I believe the need for sustainable development in schools should be mandatory and as equal important such as maths, religion and geography. The importance of learning to love nature is essential. Otherwise, we will not be able to care when threatened.
Migration and globalization
People are moving; more than 3 million people emigrate each year in the world, with over 50% move to the United States, Canada, Australia, and Germany. Globalization has led to the fact that 150 million people live outside their country of birth. The planning ahead for healthy city development is crucial, with the principal organized around the liveable condition for those who have less. Secure, clean water, sanitation, communication, water, bicycle, buses, underground transportation (ideally parts of a city should be car-free) and possibilities for school, work and access to nature in urban places. Parks should be to a lesser degree organized than those of today. Roads could be transformed into green eras with small gardens, the ability to grow vegetables and used to create livable conditions and increased well-being. Besides, air pollution in big cities would decrease significantly. Wealth and individual well-being recognized by human rights and figures from the UN confirm the differences and inequity. For a better understanding, a village of 100 people representing the world’s reputation will tell us the following about a few issues of importance.
If the world was a village of 100 people?
Who is wealthy?
- 6 persons own 59% of all wealth (all US citizens) all living in the USA
Can write and read?
- 70 persons are an-alphabets
- 50 persons are undernourished
How many own computer?
- 5 persons own a computer (US citizen)
Have an university degree?
- 1 person has university education.
Live in building?
- 80 people living in buildings
