Pollution comes in many forms, and is one of the biggest global killers. It affects 100 million people which is more than diseases like malaria and HIV ( Every year pollution claims more than 100 million land and sea animals (CEF). Not only does pollution affect humans, it is also very harmful to animals. People that live in areas with higher levels of air pollutants have around a 20% higher chance of death from lung cancer than people that live in areas with less pollution ( Air pollution seems to affect living beings more directly because of our exposure through breathing. Consequently it is not surprising that, respiratory problems like pneumonia, asthma,bronchitis, etc, are so common. The growing amounts of industrial activities and heavy useage of energy cause large amounts of pollutants like carbon monoxide to be released into the atmosphere (Zoo Granby). Air pollution is composed of gases, solid particles and aerosols that affect the natural structure of the atmosphere. Air pollution is damaging to human health as well as pets and wildlife. Studies have shown that household pets can suffer a more increased chance of tumors when they are exposed to polluted air for an extended amount of time. Particles in the air have been linked to cases of cardiac arrest in dogs. Air pollution has also been linked to the changes in the physiology and behavior in toads and many other amphibians. Birds are affected directly by the exhaust of coal power production. The exhaust Lehnhausen-2 damages birds’ respiratory systems. Birds are also affected indirectly by the increase of pH in the wetlands, which causes fish kills. This results in the reduction of osprey populations as food sources become sparse.

In 1986, lead shot became illegal for hunting waterfowl starting in the 1991 hunting season. In some countries like Mexico, lead shot is still legal and waterfowl are still subjected to lead throughout their migrations. When metal smelters are used, they can release emissions that are proven to have harmful effects on wildlife. The smokestacks at metal smelters release harmful pollutants into the air, and they eventually fall downwind of the stacks. It has been proven that the pollutants from the smelters cause serious damage to plant and animal ecosystems. Animal species that are downwind of the smelters have been proven to have high concentrations of the metals in their bodies (Marine Bio).
