Western Log Group is concerned with the issues addressed by the use of sustainable sources. One of the key issues tackled is "Environmental Degradation".
Sustainable development is a process of developing (land, cities, business, communities, etc) that "meets the needs of the present without compromising the ability of future generations to meet their own needs" according to the Brundtland Report, a 1987 report from the United Nations. One of the factors which it must overcome is environmental degradation but it must do so while not forgoing the needs of economic development as well as social equity and justice.
Environmental degradation, according to Ivan Rizki Tjahya (2006) refers to the diminishment of a local ecosystem or the biosphere as a whole due to human activity. Environmental degradation occurs when nature's resources (such as trees, habitat, earth, water, air) are being consumed faster than nature can replenish them. An unsustainable situation occurs when natural capital (the sum total of nature's resources), is used up faster than it can be replenished. Sustainability requires that human activity, at a minimum, only uses nature's resources to the point where they can be replenished naturally:
| Consumption of renewable resources |
State of environment |
Sustainability |
| More than nature's ability to replenish |
Environmental degradation |
Not sustainable |
| Equal to nature's ability to replenish |
Environmental equilibrium |
Sustainable growth |
| Less than nature's ability to replenish |
Environmental renewal |
Sustainable growth |
