The demands of a growing human population are putting increasing pressure on the Earth’s natural systems and services. Dubbed the ‘Anthropocene’, we are currently living in a period where human actions are directly altering many earth processes, including atmospheric, geologic, hydrologic and biospheric processes. Climatic change and the resulting consequences, including rising temperatures, changing precipitation (i.e. rainfall, snow etc) and increase in frequency of storm events, represent the biggest challenge to our future and the life-support ecosystems that make our world habitable.

In 1970, Earth Day was launched as a modern environmental movement and a unified response to an environment in crisis. Earth Day has provided a platform for action, resulting in the creation of the Environmental Protection Agency (EPA), The Clean Air, Clean Water and Endangered Species Acts in the US and more globally. This year, 22 April marks the 50^th anniversary of Earth Day, and the number one environmental crisis theme which needs immediate attention is ‘Climate Action’. Many of our ecosystems on earth are degrading at an alarming pace and we are currently experiencing a species loss at a rate of tens or hundreds of times faster than in the past.
