Global Warming Environment

Polar bears are found in five nations: Canada, Russia, US (Alaska), Denmark and Norway. An accurate estimate about polar bear population is unavailable, as it is difficult to find and count all of them. However, the rough estimate is that there are between 22,000 to 40,000 polar bears living today, of which more than half live in Canada.

What does a Polar Bear Hunt and Eat?
Polar bears thrive in the Arctic regions, and are not found in the southern hemisphere. This is because of the different polar bear adaptations. Polar bears have adapted to living in the cold winter conditions of the Arctic, as the Arctic region is where they have their favorite food source: the seal. The ringed seal and the bearded seal are the bear’s primary source of food. Polar bears eat the fat of the seal and leave the remaining carcass for scavengers like ravens, arctic foxes and younger bears.

Are Polar Bears Endangered?
Species which are on the verge of extinction are classified as endangered species. The question ‘are polar bears becoming endangered?’ is on everybody’s mind. The answer to this is ‘not yet’. The predominant reason of polar bears getting closer to becoming endangered is global warming. Global warming has taken a toll on the population numbers of polar bears. Today, polar bears are listed as threatened species under the Endangered Species Act of 1973. In 2005, the polar bear was reclassified as ‘vulnerable’ on the IUCN World Conservation Union’s Red List of Threatened Species, noting that polar bears could become extinct if the sea ice changes continue.

Increase in temperature in the Arctic regions due to global warming has caused the ice to melt. Ice is the habitat of these polar bears, which they use for hunting, traveling and mating. In some areas, bears spend the summer months on land and fast until ice is formed in the fall. They then use the ice as a rostrum to hunt seals in the seas. According to certain studies related to polar bear population in Canada, the period of fasting has increased by three weeks since the 1970s. Moreover, the population has declined by 15% in the past ten years. The US Minerals Management Service in northern Alaska has reported that some polar bears have drowned in the attempt to swim long distances between land and ice.

Many people are interested in my blog because they do care about our earth.In fact,we can call it  Our Future.What is the most important thing for our future? Different people should have different answers to this question.However,experts all hold the view that energy is the most critical thing in the future.Energy is such a critical resource that it affects every single human endeavor.I support this idea,too.There are many reasons for it.First of all,we can not live without energy.For example,we can not use our computers without electricity.As is known to us that we can get a lot of happiness from computers.And some people are working by computers now.That is why it means that many people will lost their jobs without energy.In addition,we also need oil to operate our cars.I am sure that many people will complain if they can not drive for several days.Second,being lacking of energy will lead to wars between countries.We have seen a lot of reports about it.With the development of economy,each and every one of us uses more energy than the previous generation.

The title of my blog is related to solar energy investments.Today,I will tell you how to invest in energy.As I have introduced the importance of energy,I will do my best to teach you how to make money from your investing in energy.According to my experience,you had better find a professional agent to help you.Many companies provide thoes services online now.For instance,you can search on Google by typing in related keywords.Generally,you should choose the agent which is spoken highly of by most people.Many people are willing to share their ideas with other people through internet.Just read them carefully and I am sure that you will find a good one.Ok,that is the end of this article.I wish that you can make much money in the future.

Korean Lawn Grass (Zoysia japonica)
The Korean lawn grass is also sometimes referred to as Japanese lawn grass, and is native to the Manchurian province in China. This variety of zoysia grass is perennial and has a coarse texture. The blades of the grass are covered with fine hair, and are light green in color. The Korean lawn grass can grow up to 12 inches in length, but is slow-growing with stiff leaves. It is drought-resistant and can withstand high temperatures. During the winter months when the temperature drops below 50° F, this grass loses its lush green color and turns to a light shade of brown. However, with the advent of spring, the grass regains its original color. This species of zoysia grass requires adequate amount of sunlight for normal growth, but can survive even in shade. This variety grows best in well-drained soil that has a neutral pH. It is the only species of zoysia grass that can be grown from seeds. However, the Korean lawn grass is prone to infestations from billbugs and nematodes.

Manila Grass (Zoysia matrella)
This was the first species of zoysia grass to be brought into the U.S. Native to the Philippines, Manila grass grows well in areas that receives moderate sunlight. The blades of the Manila grass are narrower than those of the Korean lawn grass, and are long, stiff, and covered with fine hair. Just like the other species of zoysia, the Manila grass turns brown in color during the winter months when the temperatures are very low, and regains its green color in spring. The other names for the Manila grass are Mascarene grass and Siglap grass. This type of zoysia grass grows up to 13 inches in length, and the leaves are not as coarse as that of the Korean lawn grass. A characteristic feature of Manila grass is that it can grow well even in sandy soil, where other species of zoysia grass cannot. Although this type of grass grows slowly as a seedling, it develops stolons and spreads rapidly after a period of 5-7 weeks. The Manila grass is grown from sprigs, and is sometimes referred to as the Matrella grass. Just like the Korean lawn grass, it too is susceptible to nematode infestations. Continue Reading »
