a. both have been impacted by oil drilling and mining.

Tundra biome is the coldest region on the earth. These are treeless regions found in Arctic. These are found on the tops of the mountains, and rainfall is scanty in these regions. Rain forests are forests, which are found in northeastern Australia. These regions receives maximum rainfall on earth. Oil drilling and mining have threatened wildlife in tundra and rain forest ecosystem. The exploration of oil, gas and minerals by mining and drilling processes can cause physical disturbances in the natural habitat of the wildlife. The oils and gases can be poisonous for living species of these two biomes hence, negatively affects the biodiversity of these biomes.
