There is a lot that the developed nations have to do first before asking the poorer countries. The main cause of global warming is the emission of carbon dioxide. According to this website (
http://maps.grida.no/go/graphic/national_carbon_dioxide_co2_emissions_per_capita), India lies way below the developed countries. For example on per capita basis USA emit 20 times more, Australia 18, Canada 14, Norway 11, Germany/Japan 9 times.
Coming to population, the overall population of India may be high but the population density of India is about 336 per square kilometer which is less than countries like Japan, Taiwan, SOuth Korea, etc (
http://en.wikipedia.org/wiki/List_of_countries_by_population_density). I am sure India can sustain a higher population. India has always been highly populated compared to other counrties for the last few thousand years.
If you try and find the data on the generation of waste per household I am sure that figure for India would again be miniscule compared to the developed countries.
What i would like to say is that agreed India needs to do more for the environment, but then there are other countries who lecture us on environment to do a lot more themselves before asking us. First and foremost India needs to be able to provide a decent standard of life to its citizens.
BTW, you can do more for the environment if you switch off your appliances from the mains (including your computer monitors) rather than use your remote to switch it off or put it in stand by.
