The word ecology comes from two Greek words oikos and logos.
There oikos meaning house and home, logos means learning.
So one could say that ecology means the study of house and home.
What, then, houses and homes in our case?
From a biological angle as defined ecology as the science of the organism's relationship with the environment, thus our surroundings. Where the environment is modified / affected by the organism's activities.
One could say that we humans are one of the organisms in the environment and that we are constantly affecting the environment with our various activities.
It's just really nature can produce.
With that, I would say, using energy to build up organic matter.
People can only use natural production and the production of goods and energy for their own consumption.
We use products from all steps of the natural cycle of our production. Grain or different plants that come from the basic / original production of the natural cycle as one might see as a first step. The milk or meat from the cow as a form of second phase of the natural cycle in which the cow eats the product of the first step. The oil in turn is a form of third step from all the decomposed organic matter.
What we get out of all these steps is energy in various forms where one would say that the last is the most effective and also the one that is limited.
Consumption of energy takes place at the private consumption of food, clothing, housing and transportation, etc. Then this with a certain energy input to reuse, such as newsprint, metals etc.
But one wonders if the rest of it to be broken down really make it, and if the waste can actually be absorbed by nature and do not cause any harm?
To return to the word ecology above so I now associate the soil to a home where we live in. Where some form of ecological approach should be followed for it to be able to all be in order in the home.
The difference between my home and the earth is my home, there is a trash can. There, the garbage disappears almost automatically from the home because of some responsible person. But such a thing is not on earth there must be things recycled.
People created long ago an economic system among themselves to facilitate the exchange of commodities between them. But how much do we value the economy today, then, is how value we see things around us, and this system works with each pause between the natural cycle?
There are hardly any places left on earth where human influence is not appreciable. Even the atmosphere has changed and the processes that we produce which is completely unnatural for nature. In ruling last 100 years, we have more than previously transformed our planet in a way that threatens a series of biospheric social system. But through energy certainly raised our standard of living for the moment. The basic reason for this degradation is the consumption of oil, gas and coal, of course. Natural resources loads has a pretty big connection with population growth. You can see it from an environmental perspective as the most most significant problem during the 1900s.
As an example, one can see that today China has 1.28 billion people and compare it with the population adopted achieved 2015 1:41 billions thus an increase in population at 0.13 billion. There will thus be created more people in China than the population in Mexico today. Then it is still Mexico today two and a half times people closer than Sweden. Then one can estimate that Mexico has at 2015 approximately 13.8 times more people than Sweden.
As top of everything so, China's oil consumption increased by 15.4 per cent in 2004, but now in 2005 settled down.
But they have nevertheless managed to get the world's second largest oil importer, due to its rapid economic growth.
One can also take up the world's second most populous country India which increases its average annual oil imports to 10-13 percent
