Why should it be like this?

This is so sad.. I've been reading some articles this few days for my paper in social studies.. I 've been reading articles about how climate and poverty is connected with each other.. I got maybe 20 articles from the library and excatly at this point i only read 3 of them and they already broke my heart.. like seriously this thing really hurt me so much i couldn't imagine.. now i wonder if i really want to continue with this thing.. this articles have some direct interviews from the people living in the country.. and i know some of you already felt something like this.. this is so hurtful... In some part of the world you can't even see the changes but we must think about the other parts of the world we are not the only one living in this world there are more of us who might not be as lucky as us.. like those who are in some countries that poverty is huge.. Right now, this country is almost covered with water... In some country they still talks about what is global warming, learning some words that are very hard to understand and even hard to remember but for others they really don't care what is the meaning of global warming cause they know it by experiencing the changes that it can bring to a country this might be so stupid of me to say but why do care for those hard concepts about global warming when you can see it or hear it yourself... why can't we just work so that there can be some changes I know that it can be hard to do something that can make a difference but think of the simple things you do everyday.. like instead of using the car to go to the store which is just 10 minutes away from your house.. why not instead walk.. that little thing can help.. that small thing can do so much help for the others.. sometimes i can feel that some countries are very selfish... maybe all country are selfish?? I mean they are all reaching to be on the top of the line.. they want to be strong.. they want to be powerful.. they are willing to do everything just to stay at the top of the line or i should say at the top of the game.. They don't realize how their doings effects other country.. how they effects the most needy countries.. this needy countries who need help... why can't every country help each other cause we are all at the same world.. we are all at the same boat... this is nothing to do with politics or religion or some complications between other countries.. can't we just stop thinking about it for a second and help each other instead...we are all in this..I just don't get it.. that's it.. this might be stupid but i just want to let it all out.. this is very hurtful..
