The Killer Whale has declined in overall numbers due to the environment and human actions. These animals consume tons of food daily, and that is a concern. In many areas they are consuming the same fish that fishermen want to make a living from. As the amount of food is reduced they may have to move further to find more of it. This is where they end up injured or killed due to fishing nets or boats in those areas. Some people hunt Killer Whales for sport or to consume the meat from them.
