Biologically Productive Areas

The land and water (both marine and inland waters) area that supports significant photosynthetic activity and the accumulation of biomass used by humans. Non-productive areas as well as marginal areas with patchy vegetation are not included. Biomass that is not of use to humans is also not included. The total biologically productive area on land and water in 2013 was approximately 12 billion hectares.

Earth's atmosphere

Earth's atmosphere is around 500 kilometers but the bit we are interested in lies within 16 km of the surface. The atmosphere is made up by nitrogen (78%) and oxygen (21%). There are lots of other gases in smaller amounts. These include argon, carbon dioxide, neon, helium, hydrogen etc. Oxygen is required by animals for existence and carbon dioxide is used by plants in photosynthesis.


Earth Overshoot Day

Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. We maintain this deficit by liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere.

Eco friendly construction

Uses materials and technology which help optimize energy efficiency of a home and reduce its harmful effect on the environment at the same time.


Ecological Deficit

An ecological deficit occurs when the Footprint of a population exceeds the biocapacity of the area available to that population. If there is a regional or national ecological deficit, it means that the region is importing biocapacity through trade or liquidating regional ecological assets, or emitting wastes into a global commons such as the atmosphere.

Ecological Footprint

A measure of how much area of biologically productive land and water an individual, population or activity requires to produce all the resources it consumes and to absorb the waste it generates, using prevailing technology and resource management practices. The Ecological Footprint is usually measured in global hectares. Because trade is global, an individual or country’s Footprint includes land or sea from all over the world. Without further specification, Ecological Footprint generally refers to the Ecological Footprint of consumption. Ecological Footprint is often referred to in short form as Footprint. “Ecological Footprint” and “Footprint” are proper nouns and thus should always be capitalized.

Greenhouse effect

The greenhouse effect is in effect a thermal multiplier. As various sun heat absorbant gasses (mainly CO2) build in the atmosphere they emit infrared radiation back in towards the surface in an ever increasing rate.

Natural methane is found both below ground and under the sea floor. While methane doesn’t linger as long in the atmosphere as carbon dioxide, it is initially far more devastating to the climate because of how effectively it absorbs heat.For this reason, it’s considered a greenhouse gas, like carbon dioxide.

The agricultural practice of producing or growing a single crop, plant, or livestock species in a field or farming system at a time. The practice has been criticized for its environmental effects and for putting the food supply chain at risk. Continous monocolture can lead to the quicker buildup of pests and diesies.

Water Footprint

The water footprint measures the amount of water used to produce each of the goods and services we use. It can be measured for a single process, such as growing rice, for a product, such as a pair of jeans, for the fuel we put in our car, or for an entire multi-national company. The water footprint can also tell us how much water is being consumed by a particular country – or globally – in a specific river basin or from an aquifer.
