For example, plant and rat. Although the plants seem to be finished, their roots will produce new plants. Rats are consumed by snakes, however, there will be some rats left
so that they will grow and survive. Such event happens along food chain. A constant condition with plants and animals where they are not extinct and still survive is called
equilibrium or homeostasis. Homeostasis peak means limit of carrying capacity for any ecosystem. Carrying capacity means any natural capacity of ecosystem to survive and
grow. In case ecosystem’s carrying capacity gets inputs in form of knowledge and technology, accommodating capacity will be created.
Any population continuously growing and exceeding its carrying capacity will press down the carrying capacity. Too high pressure on carrying capacity causes reduces in
carrying capacity to support life so that number of population decreases. Based on above description, it is clear that the role of environment to life can not be forced. If carrying
capacity is exceeded, environmental damages will happen. Limitation of carrying capacity is called ecological limitation.
Such ecological limitation will be more perceived along with population growth and decrease in natural resources. Therefore, to anticipate ecological limitation, following
efforts should be made:
1. To keep environmental preservation and to make environment productive for human beings;
2. To save natural resources so that they will not be quickly finished through the creation of sophisticated and energy-saving technology;
3. Development planning with environmental conception.
C. Elements of Environment Elements or components of environment basically consist of:
1.
Physical components abiotic environment like soil, rock, and climate; 2.
Biological component biotic environment like plants, animals, and microorganisms.
3. Human resources and artificial resources as products of human works and wills as
their cultural environment. The three elements can not stand alone but they are related each other. Any change in one
element will influence others. Thus, environment is a system where it comprises various sub-systems.
Those sub-systems are called elements or components of environment. Human and other organisms living on earth occupy certain spaces. In addition to living organisms, non-
living organisms are found on the space. Both living and non-living organisms are interrelated.
Relationship between human and environments occurred since human is born. At the same time, human had needed environment including clean water to breathe, water to
drink, clothes, and home to protect himherself from cold and hot weather, in which all those materials are from nature.
Basically, human can survive since it is contributed by elements of environment. Thus, benefits of environments for human are as follows:
1.
Air for respiration. No human can survive without air. 2.
Water for drinks, taking a bath, and electrical generator. Moreover, clean water has been economic object in urban area. You may often buy packaged water for drinks
where its one-liter price is higher than fuel’s price. 3.
Plants and animals are sources of animal and vegetable proteins. Other than sources of food, plants and animals can also be sources of power and pleasure. In certain
areas, buffalos and bullscows are used to pull plows in rice field and horses are used to carry wagon or means of horse riding sports. You need to be aware that oxygen we
breathe from the air mostly comes from plants during photosynthesis process. 4.
Land for constructing personal and social infrastructure. Dwelling is used to protect human from heat and rain as well as functions as social facilities like
governmental, sport buildings, and shopping center where all are built on land. Not limited to such matters, if we observe rural areas, farmers will do their routines on land.
In fact, interactions or relations among elements of environment do not only centralize on human beings. Other than interactions of humans to their environments, several other
components also interact for their survivals. For example, inter-physical components like climate and soil influence lives of biological components very much like plants requiring
water, fertile soil, and air. Biological components can also influence continuity of physical components. For example, soil worms living in soil may help to fertilize and to
enrich soil nutrition that it will be fertile. For ecosystem balance, other than using those elements, human resources should also be able to synergize and to preserve them for
ecosystem balance.
