  Radiation emission in environment - global decision making

Should new developments that could have a global impact be discussed by an indempendent global agency that would have to find a common sense/agreement ?

There are points also raised regarding administrative loopholes, wrong decision making process, capitalist mode to control on resources , lack of political will , etc? But is that human can have control upon endogenetic process or whether earthquakes, volcanism or other catastrophic event can be predicted? The answer is that all such events cannot be. And even society will grow with demand of various materialistic things as there is flow of money and increase in facility of day today life. So will be an increase in demand of energy generated by renewable and non-renewable sources. So merely by criticizing nuclear energy, thermal energy or hydropower projects we cannot just downgrade its relevance in the present world.

  Is a Natural Resource Tax a good replacement for all present existing taxes, and how big will any impact be on climate change and global economics?

Money itself should not be taxed , It should be the goods and services that should have taxes embedded in them, to reflect the environmental and social damage the use of those natural resources cause !

TheThere was a letter of a number of world leading economists including 4 Nobel prize winners to our former President Gorbachev who then destroyed the Soviet Union and finally the Russian economy. The letter was about the Land Rent or in a broder sense Natural Resource Rent, on necessity to make this rent a basis of the tax and budget system. Gorbachev and than El'tsin with their pro-US monetarist economists Chubais, Gaidar etc., made completely the opposite. 2 trillions USD since that run from Russia and origin of these money is mostly hydrocarbon and other natural rent, PRIVATIZED mostly by several people. Of course, substantial part of this rent get into budgets and this is the only possibility for the country to survive. But it is an unsustainable state, it is step by step destruction. For understanding of this topic also it is important to be familirized with the Hartwick Rule

If taxation was based on the environmental impact of all natural resources collected as near source as possible , this would enable everyone from designer to consumer to be involved in the production and marketing of goods and services based on their impact on the planet based on the price they paid for their raw materials. Carbon Trading does not tackle the real underling problem quickly enough and also allows for gamblers to take control of the already corrupt financial system which already is dictating the environmental agenda.

In most ofApart from other lofe forms, trees are habitat of wide verieties of insects as well. These insects act as pollinator and are vital agent for sucessful completion of life cycle of plants. In most of the cases, relationship of pllinators and plants is highly specific and loss of population of pollinators affect population of trees. One interesting case is that of Adensonia digitata which is pollinated by Bats.Reduced population of Bat has made this plant ritically endangered. In Jharkhand I have studied some well grown trees of Adensonia which fail to produce seeds because of lack of pollinator. Loss of green cover is major cause of loss of pollinators population.

During the monsoon most of these fish species attain peak gonado-somatic index and produce eggs. These eggs’ being sticky gets attached to submerged vegetation for ensuring fertilization and when larvae are produced they are carried by the gushing waters to safer heavens. Besides these flooded areas are easy pool of nutrients where food gets plentiful in short time.

The link to the latter is supported by a lot of theory and modeling, with a generally good match between the extent and distribution of observed warming and that predicted to folllow from climate models.
