The problem may not be very dangerous to us. Our generation or the generation of our children will not threaten the planet, but what next? What about grandchildren, their grandchildren and the rest of the human race? All of these problems are long -term that may occur, or not, you need to answer anyone. To think about it, and seek to solve it.
