How do animals become extinct?

 

 

Though Earth is densely packed with living beings, the greater part of the species that ever existed on it has become extinct. Yet before humans started spilling oil into the sea and depleting ozone layer with greenhouse gasses, species died out for certain logical natural reasons. After all, overpopulation is a threat not only to humans, and animals have their own mechanisms to regulate populations.

Climate change is one of the most trustworthy explanations for the extinction of species. About 11,000 years ago, megafauna mammals failed to adapt to a sudden climate change. It is also likely that instead of food, dinosaurs faced early humans that presented more of a threat than food to gigantic reptiles. Anyway, megafauna species by no means could survive in this new environment that formed on Earth, and their extinction made way for present-day reptiles and amphibians.

Several more reasons of natural extinction can be derived from climate change. These are a lack of food, lack of genetic diversity, predation of better-adapted species, unbearable weather conditions, and an invasion of disease. The evidence of meteor strikes is another popular theory to explain the extinction of pre-historic species.

With such a broad evidence that nature regulates populations itself, we cannot deny the impact of humans on the degradation of species. Construction and industrial activity deprive animals of their natural habitat, and the lucky ones have to migrate. Some species that have no alternative habitat (such as polar bears) can simply die out as glaciers melt. A huge human responsibility lies on pollution. If we cannot take away resources from marine species, we can still pollute them. And that  is not the activity to be proud of.

Impact of technology on interpersonal communication

 

 

Interpersonal communication is a comprehensive category that includes workplace, group, intimate, and romantic interaction. Influenced by the Internet and its advantages, communication in all these spheres has largely transformed. 90% of individuals irrespective of their lifestyles are present on social networks every day. Each of us is accessible to the others every time. Our boss, spouse or completely unknown person can contact us whenever they need. People do not hesitate to interact, they cannot see any limits to communication now. And many of them find this exact factor discouraging.

A vast sociological research conducted in the US confirmed that the increase in wealth and quality of life caused higher isolation among Americans. Constant online accessibility made communication such a routine thing you want to avoid. Many people got tired of empty chatting that took their time and did not give back anything in particular. Under the impact of technology, we became lazier: why go hang out with peers if you are already connected online?

To put some advantages of technology, it simplified business communication. In many cases, you need only safe online connection to work productively and report your progress to the manager. Even in traditional offices, communicating per e-mail sufficiently accelerates performance. Technology has simplified interaction between a provider of services and their clients. In most cases, clients do not even need to communicate with the provider to get their services.

As a result, the impact of technology on interaction is diverse. We cannot address online channels of communication as a negative phenomenon because we gain even more than we loose with the Internet. In fact, the culture of communication is individual to all people, and those who use the net responsibly never complain about how dramatically the technology has changed their lives.
