It is impossible to reach a global consensus on environmental conservation efforts. Do you agree?

I do agree it is impossible to reach a global consensus on environmental conservation efforts. In countries of poverty, environmental conservation is an idea that only the rich think about. Think about it. If you have problems feeding yourself to three meals a day, would you have the time or the energy to think about saving the environment? Similarly, poorer or developing countries have their priorities set on improving their quality of life, and as seen from the graph of London's air pollution in the article, “The truth about the environment”, developing countries first have to undergo a stage whereby pollution will reach its highest peak. The most convenient way for countries to develop happen to go against the idea of environmental conservation.
In the case of the article, “The way we live now. Why bother?” The author states down the idea that even if he chose to go totally green, changing his lifestyle right from the roots, there are still others who produces enough carbon to replace what the author’s green lifestyle saves. Hence, no matter what one does, the effect on the whole global world is in fact very insignificant. What we enjoy now may not be enjoyed in other countries. While we have enjoyed years of internet access, people in other countries may have just started enjoying their first internet experience. Similarly, while we have taken buses and cars to work every day for the past decades, people in other countries may have just started having buses as a form of transport. Who are we to tell them that the buses they ride in contribute to global warming and that they should revert back to the most primitive forms of transport? As seen from these, the rate at which society advances determine how ready the people are to accept environmental conservation ideas. Developed countries thus have to take the initiative so that developing or undeveloped countries may follow in its footsteps in the future.
Everyone enjoys the benefits of a greener earth. But who is the one doing the work? Assuming a country decides to go green, totally. Laws are set to switch all petroleum-based cars to hybrids, and all houses are to be fitted with black solar panels to generate their own energy. The neighbouring countries too enjoy the benefits without having to spend a single dollar. Given the high costs of environmental conservation efforts such as the Kyoto protocol, countries would be reluctant to do their part in environmental conservation. Different countries will also have different abilities in their environmental conservation efforts. Countries will then strive to enjoy the greatest benefits while spending the minimal effort, leading to conflicts among the different countries which feel unfairly treated. Thus it would be impossible to reach a global consensus on environmental conservation efforts.
