Pollution is the world’s biggest killer: Dirty air has overtaken heart disease, diet and even smoking-related deaths as the biggest preventable killer:
     

In 2012 one in eight deaths worldwide were linked to pollution. The main causes of death linked to this pollution are heart disease, strokes and lung disease. The World Health Organization reported that in 2012 pollution was the world’s single biggest environmental health risk. It was the leading cause of preventable death worldwide. The risks and evidence is more prevalent than ever before that air pollution is a huge risk factor that must be corrected if we hope to have a future on this earth. Indoor pollution is a large cause of cooking over coal, wood and biomass stoves. The World Health Organization confirmed that 2.9 billion people worldwide live in home that uses this thing as their main cooking fuel. Poorer countries obviously have a higher risk of indoor pollution because many of them don’t have any other cooking options. Outdoor pollution is mainly transported by power generation, industrial and agricultural emissions and residential heating and cooking. Although alternate environmental friendly products are more expensive to produce, they could in return save our environment and billions of lives. Money is obviously always going to be a factor when it comes to technology. It is the sad but true side of how far the industrial revolution and modern technology has taken us, which has left us still polluting the air that we breathe. The solution to this problem has been discovered. Technological adamants have given us environmentally friendly ways to stop this pollution and save more lives, however the world is run by people in power and people in power usually don’t give away expensive things to people that can afford them.
