I'll try to explain my opinion about this phrase "Rich industrialised nations are responsible for global warming so it is their duty to find a remedy". So, let's start.
We all know that rich industrialised nations can hurt all the planet and as result can die all beauty that our world has. I think that rich industrialised nations should take all the responsibility by three reasons. First reason is animals. I really care about animals life. You don't have to be a specialist to understand that industry can damage planet and animals. And animals can die. Second reason is because this rich nations have a lot of money. And they can pay for all that need to avoid global warming. Third reason is because it is their fault that this happened, so they should pay for what they did.
But we really need to think about that. Is it true that rich industrialised nations should fight with this trouble in their own? There is a few reasons why the shouldn't. First, whole planet hurts because in whole world people throw litter at the streets and in the fields. Litter - is way to a global warming too. So we all need to take responsibility. Second reason is that other countries may have people who can help to fight with this problem, you know, I call them specialists.
Personally my opinion is that we all should fight with this problem. Together. And there is no reason who did this. Because we all live in this planet and we should care, to wake up and look around and see only beauty, line in Edem was.
In the end, I want you to ask something. Please, love your planet. Love place where you live. Take care about place where you live as if it was you, old you, and you kids love you and really care about you. Just imagine, planet is old, and we, her kids, should take care about her. And it will says to us: "Not global warming, no, love to everyone."
