Hello everybody, How are you ? First of all my name is Chelsea Gough. I'm a scientist, i want to talk to you about  global warming , its causes and its current  consequences .       
Environment surveys show that the  Earth   surface  temperature  is rising   rapidly   , it is  called “Global warming” 
The amount of   carbon dioxide (CO2)  and other greenhouse gases like methane, nitrous oxide or fluorinated  gases  contribute to global warming. The increase of these gas emissions is mostly due to human activities : home heating ; car driving;  development of chemical plants .
The consequences of the global warming and  also pollution  is that the planet is suffering , it is sick, in bad shape, unhealthy and may even be destroyed :seas are rising; storms  are more violent; floods are more frequent ; fish and wildlife are threatened : polar bears for example may disappear.
We are destroying our Earth; our planet is menaced
We must therefore mobilize and act quickly to save the planet for the future generations!
There are many things we can do : We can take public transports rather than car ;  recycle and reuse   as much as we can ; avoid  plastic bags ;   lower the heating  or  reduce the air conditioning ;always   throw our garbage in a dustbin  
It’s simple but globally we can save our planet.
If we do not , we will have to suffer a lot of disasters
