Change in biome affect world

Change in tundra can kill the living things in the tundra this can also affect us throughout the world if were drilling in the tundra then then it changes then we may not be able to drill for oil anymore and this would stop our transportation and many other things the world uses gas for. Or if we change the tundra by drilling we could lower gas prices which would lower the price of produce and pretty much everything would go down.
