ozone depletion..restoration & politics

In recent time..there comes the news that. China & India r producing the max amount of HCFC-22.Which is slowing the process of restoration of ozone depletion.The EU countries had already stoped the production of ozone..& countries like U.S.A & Australia have decreased their production at minimal level.So they r know saying that China & India r major producer of HCFC 22.With it they also export it to other developing countries. But as per the Montreal protocal they have the time limit of 2020 to stop the ozone production.Previously the developed world thought that as the production of HCFC 22 is very costly,so its large scale production would be out of reach of developing countries.But with the booming economy the need of Air conditioners in these countries r increasing & they r producing more & more HCFC 22.. So, know the question is what the developing countries should do?Is the preaching of developing countries by the developed ones is right?

Sustainable Cities

The City is not an ecological monstrosity.It is rather the place where both the problems & the opportunities of modern technological civilization are most potent & visible.  Peter Self…..

Today more than half of the whole world population lives in urban areas & by 2025 about two thirds of the humanity will be urban dwellers (U.N Projected).

Between 1950 & 1998, the number of people living in the worlds’s urban areas increased 12 fold. By 2025 it it projected to reach 5.5 billion, almost equal to the world’s current population.About 90 % of this urban growth wil occur in developing countries. It will create different sorts of problems. The developing countries are already buzzing with huge population growth, mainly due to migration from rural areas, due to which the urban infrastructure are under tremendous stress. The shortage of water, shortage of lands, shortage of electricity, degrading traffic infrastructure, unavailibility of waste disposal sites…& especially unability of cities to take the influx of population for jobs…….

Result is clear, the growing number of slums, the increasing air pollution, water related stress problems, polluted rivers…& many more….

But few cities had overcome these problems by means of innovative approches…like Curitiba, Brazil;Chattanooga,Tennessee;Davis,Calofornia;Tapiola,Finland…..

Lets take the e.g of Chattanooga…In 1950’s it is one of the dirtiest cities in the U.S…But after 1980 the peoples & the local administartion had taken proper steps & showed the zeal to transform the fate of the city….they had taken different steps to acquire their goal, such as enticing zero-emission industries to relocate in Chattanooga, renovating existing low income housing, building sustainable water supply system for the city, renovating the transportaion policy by introducing public transport system (especially by introducing non-polluting elctric buses), & by launching recycling program….

The results were colourfull & joyous, now it is one of the e.g of sustainable cities which we know, the quality of life in the city is beautiful….

So, its now our turn to take the oath to make our cities green & clean….& make our cities a better place to live.
