Transcript of Megacities

Health Issues in Megacities Sewage Problems Other diseases seem to stalk megacities such a water-born illnesses affecting children every day. Lack of toilet facilities and sewage treatment in megacities in Latin America and Asia affect 40% of the worlds population. In fact, diarrhea from a lack of city water treatment is the worlds second largest killer of children. Poverty Big cities are often also home to high levels of poverty, unemployment, and crime.
Many urban areas contain slums and sprawling shantytowns where the infrastructure is limited and where unsanitary conditions and a lack of public services lead to malnutrition, poor health, and limited educational opportunities. Megacities around the word are where 3 quarters of CO2 emissions come from.
In cities like Mexico City, the CO2 emissions are unable to escape and there is a dense smog that continually encompasses the city. Our GOAL

Improve the living conditions and health in megacities through enforcing environmental laws, creating public recycling centers and involving the public through incentives. By:

Steffanie Cruse. Megascities are cities of over 10 million people that have grown rapidly and have a dense population, often 2000 or more people per square mile. By 2013, it is estimated that 3 out of every 5 humans on the planet will live in cities. Megacities aren't just a national problem for the United States, but instead, a global problem. CO2 Emissions Megacities Map of Megacities Health issues related to megacities as a direct result of overcrowding:
Tuberculosis: bacterial infection that causes respiratory problems
When people life in close quarters, like they do in
megacities, diseases such as AIDS, SARS or H5N1 bird flu can spread like wildfire, especially through slums, where one-third of urban dwellers live.
Living in close proximity to many other people can cause higher levels of acute respiratory infections. #1
Tokyo, Japan
Has a population of: 34,500,000
Has an annual growth of: 0.60% TOP SIX MEGACITIES #2
Guangzhou, China
Population: 25,800,000
Annual Growth: 4% #3
Jakarta, Indonesia
Annual Growth: 2% Seoul, South Korea
Population: 25,300,000
Annual Growth: 1.40% Shanghai, China
Population: 25,300,000
Annual Growth: 2.20% Mexico City, Mexico
Population: 23,200,000
Annual Growth: 2% Our purpose is not to encourage a demographic shift from urban to rural regions, but to improve the living conditions and environment in megacities. Solutions for a Green Earth Strictly enforce environmental laws. Enforcing Air Quality Monitoring Laws:

After testing the quality of the air, take it a step farther and take steps to fix it.
Provide Public Transportation
Allow fewer cars on the road in megacities
Reduction of cars on road is better for health: fewer accidents
Make electric cars more affordable Improve Waste Management Laws

Government should have stricter control over various aspects of human waste removal:
transportation of waste
disposal facility management
treatment of waste Water Sanitation

Government should put forth more effort to clean up the remaining freshwater in the world

Find ways to filter freshwater and make it drinkable
Remove the waste from the water
Prevention of any more waste from getting in the water Recycling Centers Positive Aspect of Recycling Centers:

Recycling conserves natural resources
Reduce the need for landfills
Remove trash from city streets How recycling reduces Greenhouse Gases:

1. Recycling used materials lowers need for landfills
2. Fewer landfills mean less materials breaking down
3. Fewer materials breaking down means less methane released
4. Methane is a leading Greenhouse Gas that is now reduced. Positive Effects of Recycling Centers on the Economy:
In recycled product manufacturing alone 1 million jobs have been created
Well-run recycling centers cost less to maintain than landfills and incinerators
Over time, recycling produces revenue to pay for itself.
Recycling reduces water pollution and improves global health. What the solutions will look like: CO2 in Cities Water Treatment Plants Health Improvement Involving Everyone Government Involvment

Adjusted Budget
Focus on the worst parts of cities
Tax Credts The Public

Take public transportation
Use electricity more efficiently
Participate in correct waste disposal Businesses

Offer gift cards and other rewards for eco-friendly behavior
RecycleBank gives federal tax credits that turn into points for gift cards and discount purchases on eBay
Job growth by making money from recycling
More jobs
Affordable eco-cars Influence of Education Improving education opportunities in slums will improve the overall crime in these large cities. Particularly education in countries in Asia and the Middle East would benefit from mandatory education.
