Of course it is! It's impact to the places and species, like climate change (north pole ice's melting), pollution (health issue), and habitat loss(some animal species almost extinct).
it is real but lot of it is exaggerated. doomsday predictions are nothing new.
please dont give it too much importance and neglect people who champion these issues
It is not the common masses that can make much of a difference. The USA, which contributes most to endangering the planet through non adherence to global conference recommendations, always insists American jobs worldwide are more important than climate change.
It's a real threat. Just look at the ice on North Pole which melting resulting to the rise of the sea level for example. There are a lot of example but people don't get that. If it's too late it's over, no reset.
Global Warming is certainly a real threat. But our planet does undergo periodic heating and cooling, with a frequency that runs to tens of thousand of years. If we were to measure these changes on a "human history" time scale, the threat is huge, and we could at best try to minimize that.
