Early awareness[ edit ] Levels of air pollution rose during the Industrial Revolutionsparking the first modern environmental laws to be passed in the midth century Early interest in the environment was a feature of the Romantic movement in the early 19th century. The poet William Wordsworth had travelled extensively in the Lake District and wrote that it is a "sort of national property in which every man has a right and interest who has an eye to perceive and a heart to enjoy". The emergence of great factories and the concomitant immense growth in coal consumption gave rise to an unprecedented level of air pollution in industrial centers; after the large volume of industrial chemical discharges added to the growing load of untreated human waste.
These five megatrends present major global threats for planet Earth - problems that must be solved if the world is to remain a supportive habitat for humans and other species. DW looks at causes and possible solutions.
Air pollution and climate change. Overloading of the atmosphere and of ocean waters with carbon. Atmospheric CO2 absorbs and re-emits infrared-wavelength radiation, leading to warmer air, soils, and ocean surface waters - which is good: The planet would be frozen solid without this.
Unfortunately, there's now too much carbon in the air.
Burning of fossil fuels, deforestation for agriculture, and industrial activities have pushed up atmospheric CO2 concentrations from parts per million ppm years ago, to about ppm today. That's an unprecedented rise, in both size and speed.
Carbon overloading is only one form of air pollution caused by burning coal, oil, gas and wood. The World Health Organization recently estimated that one in nine deaths in were attributable to diseases caused by carcinogens and other poisons in polluted air.
Replace fossil fuels with renewable energy. Reduce emissions from agriculture. The good news is that clean energy is abundant - it just needs to be harvested. Many say a percent renewable-energy future is feasible with existing technology now.
Barriers in policy and finance remain to be overcome. Cities plagued by air pollution The big smog: Cities plagued by air pollution Ulan Bator, Mongolia Ulan Bator is not only one of the coldest capitals on earth, it's also a city with massive air pollution.
Cities plagued by air pollution Beijing, China The Chinese capital has been suffering from smog so heavy that scientists say the city is almost uninhabitable - although it is home to 20 million people. Models suggest that 3. Having said this, it might be a surprise to learn that smog is an even bigger problem in other cities across the world.
Cities plagued by air pollution Lahore, Pakistan Air pollution is one of Pakistan's main environmental concerns. The situation is particularly dramatic in the country's second largest city, Lahore.
The smog is caused primarily by the high volume of road traffic, rubbish incineration and dust from the surrounding deserts.
Cities plagued by air pollution New Delhi, India In the nearly 10 million-strong city of New Delhi, the number of cars has increased fromto 3.
Still, it's the city's coal powered plants that are causing the biggest problem. They contribute to around 80 percent of the total air pollution in the city. Cities plagued by air pollution Riyadh, Saudi Arabia Sandstorms, like here in Riyadh, can contribute to smog forming because they increase the amount of particles in the air.
In a place like Saudi Arabia, the intense ultra-violet rays also transform transport and industry emissions into ozone. Cities plagued by air pollution Cairo, Egypt The poor air quality in Cairo causes a number illnesses among city residents, like chronic respiratory problems and lung cancer. The reason for the air pollution is an increase in road traffic and the booming industrial sector.
Cities plagued by air pollution Dhaka, Bangladesh According to a study by the Max-Planck Institute in Mainz, some 15, people die every year in Dhaka due to air pollution. Researchers found the world's highest concentration of sulfur dioxide there. Cities plagued by air pollution Moscow, Russia Even if it looks the same the world over, smog is different, depending on the city.
Smog in Moscow, for instance, is characterized by high amounts of hydrocarbons. The westerly winds which regularly plow across Moscow mean that the western part of the city generally has better air quality.
Cities plagued by air pollution Mexico City, Mexico The smog in Mexico City is made worse by the geographical location.Discover A.T.
