burning these fuels also injected new carbon blocks into Earth's Tetris game

But burning these fuels also injected new carbon blocks into Earth's Tetris game.At the same time, we cleared forests for agriculture,reducing the Earth's ability to remove the blocks.And since 1750, the amount of carbon in the atmosophere has increased by 40%,and shows no sign of slowing.Just like in Tetris, the more blocks pile up,the harder it becomes to restore stability.The extra carbon dioxide in the atmosphere accelerates the greenhouse effect by trapping more heat near the surface and causing polar ice caps to melt.
