It is time to act now. Otherwise Humans will go extinct.

This is how our planet earth will look like one day because of human activity. Most of sunlight gets reflected back to space by arctic ice which is called albedo effect. This keeps the planet at right temperatures for us. But NASA data shows that more than 30% of arctic ice melted in the last 30 years. The Arctic is warming twice as fast as the rest of the planet, at a rate of temperature change that has not been observed in at least the last 2,000 years, according to the National Oceanic and Atmospheric Administration (NOAA). Humans have been releasing lot of CO2 in atmosphere which is trapping sun's heat in atmosphere. Since 1900, earth's temperature has risen 1 degree celsius. An average of 5 degrees will wipe out 70% trees/species which may push humanity to extinction gradually. Life went extinct 6 times for various reasons in the history of earth over 3500 million years.
