Trees being felled in Kalimantan, the Indonesian part of Borneo, in 2013, to make way for a new coal mining project. Sustainability measurement is a set of frameworks or indicators used to measure how sustainable something is. This includes processes, products, services and businesses. Sustainability is difficult to quantify. [ 1 ]
Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain environments hospitable to life. [1] Life may be generated directly on a planet or satellite endogenously or be transferred to it from another body, through a hypothetical process known as panspermia . [ 2 ]
From 1959 to 1969, median family income (in 1984 dollars) increased from $19,300 to $26,700. [39] By 1969, 79.6% of all households owned at least one car, 82.6% owned a refrigerator or freezer, 79% owned a black and white television set, 31.9% owned a color television set, and 70% owned a washing machine. [40] Leisure time also increased.
The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae. Photosynthesis can be described by the simplified chemical reaction. 6 H 2 O + 6 CO 2 + energy → C 6 H 12 O 6 + 6 O 2. where C 6 H 12 O 6 is glucose (which is subsequently transformed into other sugars ...
A satellite image of the Sahara, the world's largest hot desert and third largest desert after Antarctica and the Arctic. Desert greening is the process of afforestation or revegetation of deserts for ecological restoration (biodiversity), sustainable farming and forestry, but also for reclamation of natural water systems and other ecological systems that support life.
Environmental indicators have been defined in different ways but common themes exist. “An environmental indicator is a numerical value that helps provide insight into the state of the environment or human health. Indicators are developed based on quantitative measurements or statistics of environmental condition that are tracked over time.
To pack pears in syrup, first prepare a syrup of sugar and water in a saucepan and heat until the sugar dissolves (use two to four cups sugar for every four cups water). Bring the syrup to a ...
Plant stress measurement is the quantification of environmental effects on plant health. When plants are subjected to less than ideal growing conditions, they are considered to be under stress. Stress factors can affect growth, survival and crop yields. Plant stress research looks at the response of plants to limitations and excesses of the ...
