Managing Our Changing Environment
Transcript of Managing Our Changing Environment
If we continue to pollute the air, one day, Singapore will be in the same condition as Mexico City.
It is easy to pollute the air, but it will be really difficult to clean it up.
This also applies to other forms of pollution, like water pollution and land pollution.
These pollutions not only affect the human race, but also other precious life forms on Earth.
Always remember that Planet Earth is our only home and if it is destroyed, it will be the end for us.
So start saving the earth today! What Can We Do? The rising problem of air pollution in Mexico makes it one of the most polluted cities on the planet.
The city even earned the reputation of “the most dangerous city in the world for children” as it affects them both physically and mentally.
Research shows that children are more vulnerable to toxic pollutants than adults and draw their skies grey instead of blue. The Choke of Mexico City Government's Actions to Control Pollution The contaminated air in Mexico city can be harmful for the inhabitants.
The inhabitants can get diseases that will cause discomfort in their lives and in extreme cases, death. Presented By:
Lum Wei Guo Factors affecting to Air Pollution in Mexico City Effects of the Air on the Inhabitants Industrial Growth Population Explosion Proliferation of Vehicles The large number of unregulated vehicles in Mexico City emits high levels of toxic pollutants, which in turns pollutes the air.
One of the most dangerous toxic pollutants is Black carbon, also known as soot.
Black carbon is hard to remove as it is hydrophobic, which means that it cannot be washed away when it rains. The population of Mexico City has increased from 3 million in 1950 to 20 million today.
As a population increases, there will be more wastes that are produced.
As a result, the air will be polluted faster. As the city progresses, more factories and buildings are built.
Thus, more and more wastes are produced. This wastes are usually released into the air.
This results in air pollution in Mexico City. Possible Diseases Which Inhabitants Might Suffer From Diseases that has Long-Term Effects Irritation to the eyes, nose and throat
Upper Respiratory Infections such as Bronchitis and Pneumonia
Other symptoms can include headaches, nausea, and allergic reactions Community Service Diseases that has Short-Term Effects PIICA and PROAIRE In the 1990s, the government introduced air quality improvement programs — PIICA and PROAIRE — that include a rotating one-weekday ban on private car use.
On days of high pollution, the ban extends to every second day and some manufacturing activities are curtailed.
This reduces the amount of pollutants that is released into the air. Improvement in Technology The city is investing in clean technology, such as replacing micro buses with new low-polluting vehicles that have greater passenger capacity.
These larger buses improve air quality in the region by running on ultra-low sulfur diesel. Government's Efforts The government has shown efforts to reduce the amount of toxic pollutants in the air.
This is due to the impact air pollution may have on the society and economics of Mexico City in the future if left unaddressed.
Some of their major efforts are shown as follows. The government has started a pioneer program in three poor communities in an outlying mountainous region and three more centrally located communities where green spaces have given way to concrete.
Games and activities were held to bond the community together
Workshops then helped participants understand the issues, identify community problems and needs, and determine their role in helping solve them. penis Thanks for your Attention! Chronic Respiratory Diseases
Damage to the Brain, Nerves, Liver or Kidneys
Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly
