From the beginning of the 21th century, the environment is facing huge climate change which one of the biggest threat to the planet. From that perspective, a certain group of folks is suggesting to van fossil fuels and introduce an environmentally friendly strength sources in order to save the nature of the expected devastation. However, an opponent thought is against the opinion, as they believe oil, gas and coal are crucial for industrialization, without them globe will go downward. According to my personal verdict, a new power source ought to be emphasized to replace the harmful fossil fuels, but the process needs to go slowly till the replacement source reaches its peak so industries will not be effected.
