Whale fishing
Blue whales have been heavily hunted in the past, especially in the first half of the 20th century. Massive hunting of them led to a reduction in their population. Although many countries have banned commercial whaling, illegal hunting still poses a threat to these sea giants.

Collision with ships
With the increase in maritime traffic, blue whales have become at risk of collision with ships. Ship routes often intersect with whale habitats, which leads to deaths.

Climate change and food resources
Climate change is affecting the distribution and quantity of food resources in the oceans. Blue whales, being filter feeders, depend on the availability of plankton. Changes in the ocean ecosystem affect the availability of food, which can lead to starvation and decreased fertility.

Sea pollution and noise pollution
Sea pollution from chemicals and plastics is negatively impacting the health of blue whales. Noise pollution from ships and oil rigs can also interfere with their ability to communicate, hunt, and navigate.

Paths to salvation:
International Agreements and Regulations: There is a need for stronger international agreements, fisheries controls and regulations to protect whales.

Establishing Marine Sanctuaries: Establishing protected areas in key areas where blue whales live to protect them from fishing and ship strikes.

Environmental Education: Raising awareness of environmental issues related to blue whales and encouraging sustainable practices in the use of marine resources.

Scientific Research and Monitoring: Conducting more in-depth scientific research to understand the exact causes of population decline and develop effective conservation measures.

Saving blue whales requires a concerted effort and global attention to ocean issues. They are an indicator of the health of the marine ecosystem, and saving them is important to maintaining balance in the world's oceans.
