think about agliculture

Our greenfingers eco-apartment has a vegitable garden each household.

Then, I would like to consider a few about agriculture.

Man has changed the life style to the agricultural life more stable from the hunting life. 

The way which stores food was devised and the technology which can respond was developed to the population which continues increasing. 

However, it is clear to hold many problems in the agriculture now. 

It will be faced with the serious problem that a possibility of destroying the earth itself in which we live is large, if the health impairment caused by agricultural chemicals or a chemical fertilizer, the environmental damage caused by destruction of nature, the earth damage caused by disruption of ecosystem, etc. will continue the present agriculture in the future. 

What thing is sustainable agriculture really?

the following sustainable agriculture from wikipedia

it is the agricultural thing which considered sustainability to be the maintainable agriculture (jikyu-jisoku, U.K.:Sustainable agriculture, sustainable agriculture) in which agricultural continuation is possible. 
The environmental problem about agriculture also has many things various in fact and serious. 
For example, when reclaiming farmland, there is a problem of destroying natural environment which was there from the first, such as a forest, causing the decrease in water resources by using superfluously cold water (river cold water, a lake, groundwater, etc.) required for cultivation of crops, or starting soil pollution and water pollution with agricultural chemicals. 
Moreover, it is indirectly concerned with social problems, such as the problem related to agricultural products, for example, a food problem, and a problem with which food is related safely, etc. 
It is the agriculture which taking in the view of sustainability and trying to solve these problems can maintain. 
The view and maneuver related to agriculture maintainable undisplayed 
Cyclical form agriculture 
Cyclical form agriculture carries out cyclic use of manure, agricultural chemicals, farm implements, etc. which are used for agriculture. 
It can become maintainable agriculture to use for manure the waste which comes out at stock raising, agriculture, a home, etc., or to carry out cyclic use of the garbage which comes out in agriculture. 
Organic farming
Although organic farming is originally the agriculture not using a chemical fertilizer or chemistry agricultural chemicals, it leads to using few manure and agricultural chemicals of an environmental impact by a natural origin, and can also become maintainable agriculture. 
Local supply and local consumption and food mileage 
The view which leads to reducing energy consumption and greenhouse gas by choosing the agricultural products produced by near Tokoro from the agricultural products produced overseas [ distant ]. 
Others
The trial which heightens productive capacity through improvement of a species, or reduces necessary quantity of agricultural chemicals or manure also occurs.

think about Nature

think about Nature

How much we could understand the Nature?
For example, if you release an apple from a hand, it will be dropped on the ground. Becase of gravitation force. There is no trick.
Oil is natural resources. Which made of animals and plants remains. It wasn't scientificaly composed.

I think We should never forget that economy realize benefit from nature and use nature now.

Below "about Nature" extract from wikipedia

We simply considered nature can be use as much as we like for about 50 years ago.Also,we imagined that the nature on the earth called it the thing it is absurd and huge and strong, and it was innocently bundled with not having a big bad influence to whole [ on the earth ] it being natural, even if human beings add a hand.And human beings have added the hand using various technology automatically (its desire goes freely) for the sake of their convenience. Human beings reclaim the tropical rain forests of a vast area until now using a heavy industrial machine etc., and change into artificial farmland etc., and have annihilated much animals and plants. Moreover, there are contamination, deforestation, an oil outflow, etc. as a threat which the human being to the natural environment of the earth causes. The natural environment without the influence of man is decreasing quickly.

If it becomes in the second half of the 20th century, although the percentage of the human beings to the amount of living things on the earth is very small, it will have come to be understood gradually at last that the influence which human beings have automatically is so great that it un-balances.An ecosystem is a much delicate existence rather than people were imagining once.   It has come to be understood gradually that man needs to consider natural environment more. It is also understood increasingly gradually that there is the complicated feedback loop of change which use of new technology gives to environment. (ecology)It is understood increasingly in recent years that change which human beings give to natural environment relates also to whether our civilization may continue in the future closely. (sustainability) It not only debates by the international conference of relation, but an environmental problem and ecology pose now a problem which the government of every country in the world also thinks as important and which cannot carry out a problem and disregard, and the Parliament of each country is often treated.
