Since whales are killed in whaling, I'd Think it'd be pretty obvious that whales are affected by whaling.

Australia has not had a whaling industry since 1978 when the Federal Government of the day decided that any form of whaling was unacceptable and, legislation was introduced (almost over night) protecting all types of whales in Australian waters.
America is against whaling. They almost put whales out of the ocean for good when they did do whaling. They wanted their blubber for oil.
Whaling isn't good at all
Commercial Whaling has been banned since 1986 by the International Whaling commission. However, scientific whaling is allowed to strict quotas.

Whaling stopped in Australia is 1979
Whaling happens in oceans, not on continents.
If you mean whales, they die painfully.
Protesting and intervening with whaling ships
Well scientific whaling as basically when you do scientific research on whales. This is actually one of Japans excuse for whaling but of course their lying they use it for food and oil and all that (STOP WHALING!)
