The cell membrane and the associated transport proteins found in the membrane are responsible for regulating the movement of hundreds, if not thousands, of different types of molecules into and out of the cell.
Among the gases emitted when fossil fuels are burned, one of the most significant is carbon dioxide, a gas that traps heat in the earth's atmosphere. Over the last 150 years, burning fossil fuels has resulted in more than a 25 percent increase in the amount of carbon dioxide in our atmosphere.
It causes pollution. Fossil fuels are bad for the environment because they create greenhouse gases which go up in to the atmosphere and magnify the suns heat which can cause ice caps to melt then that leads to the sea level rising which causes flooding and if too much ice melts animals in the Arctic could die.he burning of fossil fuels is bad because it causes carbon dioxide levels to rise in the atmosphere. This extra carbon dioxide adds to the enhanced greenhouse effect causing global warming.
