There is no denying that climate change is a serious and dangerous issue. It is important to highlight that we might face some very severe consequences unless we start doing more in order to tackle this problem. Yet, what is also significant in this respect is that we need to teach others how vital it is. More attention should be paid to climate change in schools and universities as we need to explain what should and can be done in order to prevent the global catastrophe.
One of the most efficient ways to do that is to provide vivid examples or even to travel to those places in which the impact of climate change can already be noticed. It is time to dispel the myth that climate change is something that certain people made up in order to intimidate others. It is a serious issue which concerns the whole mankind as its consequences can be observed on every continent. Need details? Want to find out more? Would like to take a look at some examples?

The general concern regarding zoos is that animals are kept in captivity there. Thus, it is not their natural habitat and they are not able to go whenever they want. What is more, people come to the zoo to look at animals which may be quite disturbing for animals themselves as well as violate their privacy.
Yet, there is another aspect to take into consideration. The thing is that there are lots of zoos the conditions of which are exceptional. Thus, every animal has a lot of personal space. What is more, a properly organized zoo is a great place for researchers and scientists to do their job and to make the life of animals better. Apart from that, zoos do a lot in order to prevent the extinction of species. In such a way, they help our planet a lot, to say nothing for the fact that animals at the zoos do not have the fear of being killed by other animals or even hunted by people. Zoo employees do their best to make the life of animals as comfortable as possible.
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.
The idea of space colonization seems very progressive and exciting. At the moment when we still dream of a trip to the moon and back, someone already hopes to build housing in the space and settle down among the cosmic landscapes. This idea has become a plot of breathtaking sci-fi dramas that blow up our curiosity towards the life on the other planets. Especially when our own one is almost neglected. In the time when NASA struggles for every bit of governmental funding, we can speculate – do we really need to make colonies on Mars?
Among possible advantages of space settlement, the ability to obtain new land without making a global conflict of it is the most precious one. The surface of Earth is not only limited but also unavailable because of the oceans, glaciers, mountains, and piles of garbage. It will not be the problem on asteroids that can provide more land than our 7 billion of people need. We also get excited with cosmic environment very different from that of Earth. Just imagine super-urban environment among stars and routine in conditions of zero gravity.
However, not all people will appreciate living in a fantastic space. Those who like blue and green nature of Earth will not appreciate artificial objects constructed in the orbits where there is nothing but darkness and emptiness. After all, our planet is a beautiful place to live, and we cannot deny it. It is also unique, there is probably no other such Earth in the universe. Therefore, think properly before you decide to settle on some strange orbit. Perhaps, all fascinating things are still there.
