G7 group concern about the risk of China on East Sea

Leaders of the group of seven industrialized nations (G7) development expressed concern about tensions in the sea, while China's Communist Party newspaper lampooning of Japanese policy in the G7.

November last year, China announced the establishment of non-recognition on the East China Sea, the move encountered opposition from the United States and its allies in the region.

In a recent interview with the BBC, Professor Carl Thayer, from the Australian Defence Force Academy, said that China may use 981 Hai Duong rig to go to establish an air defense identification zone in the East Sea.



Biodiversity

Biodiversity is the richness of genetic resources, breeding, species and ecosystems in nature.
Biodiversity is considered under 3 level:
Biodiversity at the species level includes all living organisms on Earth, from bacteria to plants, animals and fungi.
At the population level of biodiversity including the genetic differences between species, genetic differences between populations living in different geographical isolation, as well as differences between individuals living together in a community.
Biodiversity also includes the difference between the communities in which living species and ecosystems, where the species as well as the biomes exist and all the differences of the relationship cooperation between them.
Vietnam is rated as one of 15 countries with biological diversity (biodiversity) high in the world. But due to the many natural elements, pollution, invasive species invade, especially the impact of humans through various means such as deforestation, overfishing is considered to be the original ... main contributor to the decline increasing biodiversity.
Statistics show that the country has more than 21 thousand species of plants; nearly 16 thousand species of animals; 3,000 species of microorganisms and fungi mainly concentrated in some areas of high biodiversity, such as Hoang Lien Son Mountains, north of the Tay Nguyen, Southeast ... However, Vietnam and more countries in the world, is facing a serious deterioration of ecosystems rich in biodiversity. The total number of animals and plants in their natural wild endangered our country is now 882 species (listed in the Red Book, 2007), an increase of 161 species compared with the previously published Red Book (year 1992-1996). Worrying, there are nine animals (rhino horns, cow gray, tapir, otter civet, carp original Japanese eels, fish brackish lower body, spotted deer, crocodiles lilac) and two species lan comedy is considered extinct in the wild ...
The statistics of the Department of Conservation biodiversity (VEA) shows: There are 94 species of plants and 48 species of aquatic invasive. In particular, there are exotic aquatic species in Vietnam in large numbers, such as yellow snails, mimosa trees ... so do not be controlled, closely examine the situation should have occurred outbreak in the wild. Consequently, the dominant invasive species, depleting species, genetic resources, disrupting the structure and function of ecosystems. Destroying crops, reducing crop yields, livestock and even affect human health ...

Clean Water

Water holds a special role in the life and survival of human development. Clean water is life, people, animals and plants will not survive without drinking nuoc.Nuoc safety and hygiene are the decisive factor for poverty reduction and sustainable development.



Water is so important, but now, the world must still face the risk of water shortage and water pollution are serious. Pollution of water resources, lack of clean water increases the risk of intestinal diseases, skin diseases and some diseases khac.Trung average about 1.5 million children die from diarrhea each year . According to WHO estimates that up to now has about 130 million people are faced with the use of contaminated water with arsenic concentrations above the allowed concentration of 10 mg / liter. Therefore, the role of water for life important and necessary than ever.

The issue of water and human life - Water & Health
Source of water for domestic increasingly polluted and depleted
The demand for water for domestic, industrial and agricultural production is growing strongly along with the socio-economic development and population explosion. According to the results of the evaluation in 1999, 8.8% of the total annual flow frequency corresponding to 75% of the total amount of water needed by the country. This figure increased to 12.5% in 2000 and 16.5% in 2010. 41 km3 (accounting for 89.8%) in 1985, up 46.9 km3 (1990) and 60 km3 in 2000 ( 85%) is the total amount of water used to irrigate crops, this figure accounts for a high percentage. The amount of water used for agriculture in the dry season is very large. The total amount of water used in the dry season of 2000 reached 70.7 km3, accounting for 42.4% of the total water supply capacity in the dry season, or 51% of the dry season flow corresponding to the frequency of 75 %.

In many areas and river basins, water can be used several times the total amount of water can be provided, meaning that not only far exceeds the threshold amount of water required to maintain ecological but also no water at place to provide for living and production.



As mentioned above, the increase in population and human activities will increasingly strong impact to the natural environment in general and in particular the aquatic environment.

The vast green forest in Truong Son, Highlands, northern mountains are cleared to leave the mountains, barren, gray, farming and forestry irrational and indiscriminate waste into the waters ... has and will cause very serious consequences, making depleted water resources, pollution and drought likely more intense. The risk of water shortage is exacerbated, especially in the dry season in areas of low rainfall.



Fresh water is a renewable resource, but the use of these resources must be balanced between stocks and renewable. That was how people should care about, made to survive and develop life-stable, durable.

We also save green forest and water resources of us? We have the ability if we knew each startled, stopped, started again. Now to end all mining activities rampant, destroying the remaining forests. Reforestation, restoration of green for the forests. In order to hundred years later, our children can palm a handful to sip cool water pure, tasty drink stock back on every river, creek. For the life was saved, proliferation, development and longevity.
