Pollution isn’t just something that occurs outdoors and to wildlife. There are real impacts on human health that not only can contribute to sickness and morbidity, but also cause early deaths and economic disparity. Given the social impacts of pollution inequity, it is no wonder that the women of the world tend to [...]

Not all ozone is created equal. This simple molecule which is simply three oxygen atoms held together is also known as trioxygen. It is far less stable than the more usual dual oxygen that is more commonly found in the atmosphere at breathing level.
When comfortably floating above the atmosphere as the [...]

When sulfur and nitrogen dioxides (both common by-products of coal and other fossil fuels) are emitted into the atmosphere, they often fall back to Earth as acid rain. While normal rainfall has a very slightly acid pH of about 5.6, acid rain can be so highly acidic that it is capable of literally melting [...]

Corals are an entire class of animals that are among the most threatened creatures on Earth. While you may think an organism that more closely resembles rock would be immune from pollution, these creatures are not only immobile but reside in some of the most commonly polluted areas: warm, shallow seas.
Growing very slowly, corals [...]

It may seem counter-intuitive that aluminum could be such an environmentally friendly substance, but when recycled, as much as 95% of the energy spent on “virgin ore” is saved. This is significant. Not only is less energy used to get it, but less polluting substances are expelled while processing the ore. [...]

One of the most powerful air pollutants is the naturally occurring organic gas, methane. It is a far better greenhouse gas than carbon and is now found in the atmosphere at concentrations of more than 150% over pre-industrial levels.
When people put organic matter in the regular waste stream, these coffee grounds and sandwich crusts [...]

Pollution doesn’t only affect human health directly. It also has a tremendous impact on the natural environment and the organisms that inhabit it. This is especially true for endangered and threatened species that rely heavily upon specialized environments or lie high upon the food chain. Whether as a consequence of habitat destruction, [...]

The spread of pollution affects both humans and wildlife worldwide. However, unlike human beings who are capable of surviving just about anywhere, most species are reliant upon specific environments for their survival.
Climate change, for instance, has already been responsible for changing the distribution of species worldwide. Many of these organisms, whether [...]
