Apocalypse how?

hi guys!I've just watched a documentary called"Apocalypse how?", it shares the views of scientists all over the rld, how the world is going to end,there are many theories but the one that i paid much attention to is the one on global warming.It talks about what global warming is, increasing in temperature ,melting glaciers and other disasters.Global warming is the warming effect of the Earth,due to excess CO2 emissions from industries and vehicles,these has led to the increase in temperature all over the world.You might think,"So what?"well, this also cayse the melting of glaciers and increase in sea level.You also might think that you're not living in the coastal areas, "scared what?" Well, it is predicted if this goes on, flooding a florida and londan will soon happen!Later, they talked about how 6 degrees could change the world.1-2 degrees might lead to the decreasing production of crops and the whole world will be affected, estimating that many would starve and most of the coral reefs and animals will be extinct.3-4degrees will eventually melt marjority of the glaciers, increasing sea level, warming the oceans up,more hurricanes.5-6 degrees will make most of the lands BONE DRY!This aren't made up, their facts!Not trying to scare you,but all these could happen sooner than you think,we have to start taking actions, try harder.Earth is the only planet that supports life in the slolar system!Our only home, we must protect it.
