The ecology of fire is a fascinating and important subject that we need to clearly understand. Fires are powerful forces of nature that have the ability to destroy, define, and shape ecosystems. While fires can be extremely destructive, and devastating to the environment, they are natural processes that are an essential part of ecology, and are widely used as a land management tool. Fire is a reaction between various components of an ecosystem – a fire needs three basic elements to sustain it: fuel (vegetation or combustible material/liquid/gas), oxygen (air/wind), and an ignition source (spark).

Nuking Nature: The Effects of Electromagnetic Fields on Birds, Bees and Trees
Cellphones and other wireless devices function by means of electromagnetic fields, which we cannot see, and therefore don’t really give much thought about. But, could these electromagnetic fields – that we are surrounded by on a daily basis – be compromising our health, and the health of the environment?

Skating on Thin Ice: The Effects of Melting Ice Sheets on Polar Ecosystems & The Earth
Glacier melts around the world are an area of concern, especially with regard to loss of precious freshwater reserves. However, melting of ice sheets is most dramatic in the polar regions, where ice sheets and glaciers are diminishing at an alarming rate in both the Arctic and Antarctic regions.

Algal blooms frequently occur in coastal ecosystems, and in slow flowing rivers and lakes. The impact on these environments can be quite dramatic, and is often associated with high fish mortality and loss of other aquatic life. Learn more about the causes and consequences of algal blooms in aquatic ecosystems.
