you are the light of the world

This bird shows how diverse the animal kingdom is. The different type of adaptations of these birds really tells a lot about the variety ecology has to offer. The ability to live in sandy hills gives a great advantage. These sandy hills give ample protection to these birds. Also the fact that these birds live in large colonies adds to their protection. They have grown feathers which are in pale color to resemble the sandy hills. It will be really difficult to spot these clearly by birds of prey.

Also the fact that these birds are nimble and quick in movement also helps in their protection. This is perhaps the main reason that this bird has thrived. They don't have a lot of natural predators, the main reason for this is that its strong defenses. It's really wonderful to observe this kind natural adaptations which help the species grow. This bird has evolved successfully and its adaptations have helped the bird to thrive and build a big population. This is quite evident as this bird can be spotted easily in its habitat and it is a species of least concern in the wild life welfare associations.

This bird has adapted quickly to changing climates. In the recent years due to changing climates, increase in temperature and increase in the pollution, many species are finding it difficult to thrive. But in the case of the sand martin it is quick to adapt. It has so far has shown no signs of struggle or discomfort to the change in conditions. It will remain to be a favorite among the bird watchers.

The danger to the ecological balance by introducing a new kind of species in to the ecology is well known. There are plenty of examples, where the ecological balance is affected when a new species is introduced. There may be adverse effects as the species may pose a threat to the other species in the ecology. The threat may be direct or the new species may compete with the older species for food and shelter. This was a huge cause of concern for the biologist. They did fear for the other species of birds when they learned that the ring necked parakeet was introduced in to the wild.

There was a law in parts of Europe banning the breeding of this species in the wild. But these parakeets are breaking the law. Following an accidental introduction of these birds, they have been thriving. They have called London their home. It now features in the list of species that are common in London. The thing which is relieving is the fact that, the introduction of the ring necked parakeets has not caused any change to the ecology. They have also not posed any threat to any species. The species has been thriving.

The biologists are a bit weary and perhaps a bit concerned t about the introduction of this species. They are worried about the fact that as this species is thriving and is becoming more and more common. In the future when there is a lot more of this bird they may compete with other species of birds for food and nesting sites. When other species of birds face competition then they might struggle and eventually lead to the destruction of the particular species. But there is another section of the biologists who believe that there will be no such problem in the future. They say that these birds will eventually reduce in the number as they themselves will face competition. So it remains to be seen whether these wonderful creatures will be detrimental to the ecology or not.

The effect of the global warming is increasingly clearer its effects are felt largely in the Antartica. The whole landscape is changing in this area due to the melting of ice.

Recent events of large ice cracking due to the receding ice shelf have raised concern among the scientists.

The scientists have said that events like this will increase in the future. Many of the icebergs in this area are floating away completely changing the landscape of this region.

The scientists are wondering about the, long term effects of these changes.

The stem cell research has always had a lot of potential in curing many diseases. Now scientists have managed to create sensory ear cells which help in hearing.

These cells are seen as a cure to many types of deafness. The deafness caused due to loud noises can be cured by this method.

Although the cure can take about two more ears to be actually used, the possibility of a cure comes as a relief for many people suffering from this ailment.

There has been a lot of debate over the stem cell research. The use of stem cells has been opposed; many call this as an act against god. The stem cells have a lot of potential in various cures. They can be used to grow any kind of cells.

This will help patients with chronic ailments and deafness. The American president has removed the ban on stem cell research; this comes as welcome news for many, who may benefit from the stem cell treatment.

It is very important that stem cell research is encouraged so that many people can be relieved from their ailments. It is also important that an alternate method of acquiring these stem cells is found.
