No more polar bear?

We all know that the Earth is growing warmer and warmer. This problem is called “global warming”. We also know that global warming is causing a lot of problems. Ocean levels are getting higher and higher. Because ocean levels are getting higher, storms are getting stronger and stronger. This list of problems goes on and on.

Animals are suffering a lot because of global warming. Polar bears are suffering more than most animals. This is because polar bears live in the North Pole. In the North Pole, global warming is making ice melt. Polar bears hunt from large pieces of floating ice. They jump off the ice and hunt for food. Polar bears have to swim and find these floating pieces of ice. These days, they have to swim farther to find the floating ice. Many of them don’t have enough energy. They get too tired, and they die in the water.

Polar bears are suffering because of other problems, too. Pollution makes their water dirty. Many countries go to the North Pole to look for oil and gas, and they damage the environment of the bears. In addition, when ships sail through the North Pole, they cause a lot of damage. Finally, people hunt and kill too many polar bears. However, melting ice is definitely the biggest problem.

Right now, there are about 25,000 polar bears in the world. If global warming continues, there may be only about 12,000 in the year 2050. By the year 2080, that number might be much smaller.

It is important to study polar bears. When we learn about polar bears, we also learn about the health of the North Pole. If polar bears are doing well, then the environment in the North Pole is probably healthy. If polar bears are suffering then there are probably serious problems in the North Pole.

Right now, governments around the world are working to help polar bears. There are new laws that protect polar bears. However, if global warming continues to get worse, polar bears may disappear forever.

Hunting down the truth about killer whales

Hearing that killer whales are in the area is sure to strike fear in the heart of anyone at sea. The thought of coming across a creature with a menacing name like that is a surefire sign you are on a path to destruction. As it turns out, killer whales, orcas, are actually highly sophisticated creatures that are usually harmless to humans.

The title “killer whale” may actually be a mistranslation of the Spanish term “ballena asesina”, which means assassin whale. Orcas were nicknamed this due to their well-coordinated attacks on marine life, not for the danger they pose to humans. At nearly five to seven metres in length and a weight of over six tons, orcas are one of the largest creatures on the Earth. There are about 50,000 orcas worldwide that are spread out in several oceans. Orcas are classified as an Apex predator, which means no other creature hunt them for food.

Scientists believe that there are between three to five different types of orca and they are all quite distinctive. The most frequently seen of these are Residents. They live in close-knit family units called pods, which can contain over 50 members, and their diet consists mainly of fish. Transient whales, however, prefer to travel in smaller groups of two to six whales. Meanwhile, Offshore whales were only recently discovered in 1988. They prefer to swim farther away from land than the others and several pods may come together to form groups as large as 200 whales. Although these orca groups may seem similar to the naked eye, they are extremely different in many ways, and scientists believe they haven’t interbred in thousands of years. Researchers also acknowledge that their knowledge of orcas is limited, and even more groups may exist.

Male orcas have an average lifespan of about 30 years, while the average age for females is 50. However, there have been cases of females living up to 90 years. Yet when kept in captivity at marine entertainment parks, their life expectancies drop dramatically. In fact, it seems that the biggest threat to orcas these days is humans. Between the practices of hunting orcas, polluting their environments, and capturing them for entertainment purposes, we are making it very difficult for them to survive. Perhaps the killer whales aren’t the real killer after all.
