Human's Negative Effects On The Tundra Biome

Humans have a negative effect on the tundra biome. Some of the effects are overhunting, global warming, oil drilling, and pollution. When endangered species encounter these issues they die and eventually become extinct.
An example of overhunting is how sailors overhunt musk oxen and caribou for their fur and body meat. The fur gets used for clothing and the sailors eat the body meat. The musk ox is nearly extinct due to overhunting. When you over hunt a whole species, that species may go completely extinct, if they go extinct then that messes up the whole food chain/web. The excessive hunting of the polar bears hides, meat, fat, and flesh have caused a large portion of the population to die off.
Polar bears also became an endangered species
