All of us are in the same boat, what has been happend here, should affect others there, our planet act as a small village all of us live in it. So all people should cooperat to maintain it as clean as possible, and its atmosphere as pure as possible, to preserve its properties and climate which affect all livings, plants, animals and humanbeing .
In case of my point of view, poor people have no enough awareness towards the envirnoment or their behaviour against it, you may find some of them reject the wastes in any where, without any consideration to the consequences of such a disposal on the surrounding environment.
As we know, due to poverty, most of the poor people may be uneducated, so that you will see lower degree of hygine and healthcare measurements, that will leads to some epidemic diseases as Poliomyelitis, which couses paralysis to the children if they have not been vaccinated before one year of birth. And Malaria which couses death to so many of poor people in africa .
All this conditions, affect not only the country in which it occur but, in the same time all other countries . More over, if we helped them we may eradicate diseases like this from the world. As example Poliomyelitis, where the WHO can lower its ratio to a much extent, it has approxemately disappeared in Egypt .
For instance, we can not speak about our planet's climat or environment or global worming or any of this aspects, which the recent scientific researchs discuss now, we can not discuss this aspects with some uneducated, poor, and sick person who suffers poor feedig . He will not apply all this measures which needs awareness and high lifestyle .
Second, We should help them for the benifets of all the humanbeing where, what happened in the far east will affect in the far west. that is our fate .
From another point of view, some opponents say that, we can not help them for ever, they should depend on themselves, work and develop their countries through their efforts not depending on our resources, they are lazy do not give their work the required effort and devoted time to allow their country to be like the well developed, first world countries .
To sum up, developing countries are in need to lend them a hand, not only for themselves, but in the same time for ourselves as well. Otherwise all of us will suffer what is still unknown about our planet climate and global warming .
