“Framing the conversation about gun violence in the context of mental illness does a disservice both to the victims of violence and unfairly stigmatizes the many others with mental illness,”

Deforestation and soil erosion

Land pollution, in other words, means degradation or destruction of earth’s surface and soil, directly or indirectly as a result of human activities

Every year, 20,000 to 30,000 people in the United States are sickened by accidental carbon monoxide poisoning

Natural sources include volcanoes and forest fires while human sources (which make up over half of all carbon monoxide produced) are mainly vehicle emissions and slash and burn agriculture, but also include some industrial activities.

Topic(s): Atmosphere, Climate, Lithosphere, Oceans   Scenario: "Carbon monoxide suspected in teen deaths" This headline was from a national news presentation, but all too often, we see similar headlines throughout the United States due to faulty heaters or cars left running in a closed garage. Fortunately, carbon monoxide is present in much smaller concentrations in the atmosphere. There is no question that carbon monoxide is a pollutant with potential to harm all living things. But, does CO also affect Earth's climate? Unlike carbon dioxide, a compound that contains the same atoms as carbon monoxide, carbon monoxide is not known as a direct contributor to climate change. It does, however, play a role in this area.Carbon monoxide is different than most pollutants. It can persist in the atmosphere for about a month and can be transported long distances. However, it is not uniformly distributed around the Earth. This NASA Science Brief on Carbon Monoxide explains the issue further.Although carbon monoxide is only a weak greenhouse gas, its influence on climate goes beyond its own direct effects. Its presence affects concentrations of other greenhouse gases including methane, tropospheric ozone and carbon dioxide.Carbon monoxide readily reacts with the hydroxyl radical (OH) forming a much stronger, greenhouse gas--carbon dioxide. This, in turn, increases concentrations of methane, another strong greenhouse gas, because the most common way methane is removed from the atmosphere is when it reacts with OH.

Lab and field studies are showing that the more carbon dioxide pollen-producing plants—especially ragweed—are grown in, the bigger they grow and the more pollen they produce,”

Knowlton says. “Mold exposure can precipitate asthma attacks or an allergic response, and some molds can even produce toxins that would be dangerous for anyone to inhale.”

Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season and more pollen production).

air pollution not only contributes to climate change but is also exacerbated by it

We know a lot about how cigarette smoke can cause [health] problems; air pollution is doing the same thing,

increased risk for heart disease and lung cancer

The smoke from wildfires remains in the air for a long time and can travel long distances, Kinney said. This type of air pollution kills nearly half a million people prematurely every year, worldwide

Higher temperatures draw moisture out of the soil and into the air; this dries out the soil and, in turn, dries out the vegetation, making it more vulnerable to wildfires,

"While we've been damaging the Earth's climate system … we've also been damaging our own health in the process," Kinney said,

Air pollution is one human-made factor that is trapping sunlight and causing climate change,

Age is a big component, but it can depend on things like the time of day

Trees, like other green plants, use photosynthesis to convert carbon dioxide (CO2) into sugar, cellulose and other carbon-containing carbohydrates that they use for food and growth. T

Carbon needs to be pulled out of the atmosphere and put into long-term storage elsewhere

As a result of these elevated levels of carbon, our forest ecosystems are changing.

Carbon returned to the atmosphere when it has been used by trees or other organisms as energy for life is called “respired carbon.

whether that is 10 or 500years.

Land pollution is the deterioration (destruction) of the earth’s land surfaces, often directly or indirectly as a result of man’s activities and their misuse of land resources.

Depending on the level of exposure, lead can adversely affect the nervous system, kidney function, immune system, reproductive and developmental systems and the cardiovascular system. 

At the national level, major sources of lead in the air are ore and metals processing and piston-engine aircraft operating on leaded aviation fuel. Other sources are waste incinerators, utilities, and lead-acid battery manufacturers.
