Environmental hero environmental problem and do you solve

View Slideshow More than four decades after the first Earth Daythere are still many environmental concerns for communities around the world to address; perhaps none so pressing as man-made climate change. But progress is being made, and it could be argued that awareness about environmental issues is at an all-time high. Your home and transportation could be major sources of greenhouse gas emissions.

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.

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. 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 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. 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.

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.

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.

Who can edit:

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. The city is surrounded on three sides by mountains.

Due to the high levels of sulfur dioxide and hydrocarbons in the air, Mexico City was long considered one of the most polluted cities in the world. The situation is now improving due to new transport policies and certain factories being shut down. Species-rich wild forests are being destroyedespecially in the tropics, often to make way for cattle ranching, soybean or palm oil plantations, or other agricultural monocultures.

This requires strong governance - but many tropical countries are still developing, with increasing populations, uneven rule-of-law, and widespread cronyism and bribery when it comes to allocating land use.

Insome 27, square kilometers went up in flames — a global negative record. Burning down the Amazon Trading wood for wheat Intensified soy and wheat cultivation are partly to blame for the destruction of the rainforest.

Destruction there rose by percent between August and Juneaccording to the Imazon Institute. Near the city of Novo Progresso alone, some hectares of forest were torched.

The illegally cleared areas in the Amazon region are often used by cattle breeders as pasture land.Do you ever think about oil?
