hot vs cold  

yes, earth is very hot ... what happens if the complete polar ice melts ...
it is beyond my imagination - do we survive after that ? - we may not :sad:

trees are chopped down - buildings are standing high ; its
concrete jungle everywhere ... farm fields are dried out -
factories are set up in place of fields ... villages become
small towns - towns converted into cities - all cities are
becoming polluted ; we are also struggling with the waste ..

what is the development we are achieving ? where do we go ?

that's true earth are so hot, and getting much hotter everyday.. .And it cause by us that's why it happen. What we can do is contribute good thing to our mother nature, switch off electrical appliances when not using is a big help and putting in a right place garbage are helpful.. This things is our concern let help..
