The tundra biome is under threat by global warming. Green house gases are contributing hugely to the development of global warming which in turn means that the climate temperature will rise causing the atmosphere to heat up significantly. Global warming is going to melt all of the snow in the tundra biome and can cause floods in the small towns because the tundra biomes can have up to 80 percent snow. So the only reasonable explanation to solve this problem is to cut down on green house gases. Green house gases are causes when fossil fuels (like coal) are burnt and the gases from that go into the atmosphere. So we need to stop using fossil fuels. People have started to use solar to power their hot water and electricity but the solar panels alone so they still use the fossil fuels that most people use. Also the government are using wind turbines to try to power homes as seen above. But that still isn't enough to power the homes just by them selves. So there is no real why of powering homes without fossil fuels. Or is there? Lighting has an incredible amount of electricity and if we can harness that power we could run city's for decades. So all we have to do is harness the lightings power to stop using fossil fuels to stop the green house gas emissions to stop the melting of the snow in the tundra biome.
