Would you like to live in a greener world






Astronomers these days can do the most amazing things. There isn't much in the universe far beyond our solar system that they cannot find when they want to. They can find out the size and the character and even potential habitability of planets so distant from the Earth that it would take half a million years to get there in a spaceship. Some scientists think that there must not only be life in other galaxies, but even thinking beings like humans, who live longer than us and have more advanced civilizations.

But if we restrict ourselves to our solar system and try to get all the available scientific information about it, we will be disappointed to learn that our Mother Earth is the only inhabited planet among those that orbit the Sun.

Now, a natural question is why aren't any other planets inhabited? Why isn't there at least any primitive life on them?

It would hardly be an exaggeration to assert that the planets within the scope of the solar system have been explored fairly well, and according to the modern range of scientific findings, none of them can have any life on it for several reasons. To simplify the scientific language it would be enough to say that some are too big, others are too small, none have the right structure, some are too far from the Sun and correspondingly too cold, others are too close to it and, naturally, too hot. There is neither water nor atmosphere on any of them.

So aren't we lucky to inhabit a planet that has all the necessary properties for life, and even very advanced forms of life to emerge and evolve?

Our mother planet makes us remember from time to time that it isn't exactly a paradise. There are floods and storms, merciless frosts and unbearable heat and other unpleasant surprises caused by natural reasons.

However, we have realized that we ourselves have a very damaging effect on the condition of the Earth, caused by the way we live our lives today. Pollution from cars, factories and power stations is causing harmful greenhouse gases to build up in the Earth's atmosphere. These gases prevent heat from escaping - they trap heat, and as a result our planet is getting warmer. This process is known as global warming.

HOW MUCH WARMER IS THE EARTH LIKELY TO BECOME? *

Scientists predict that if no major efforts are undertaken to reduce the greenhouse gas emissions by 2100, the Earth's average surface temperature will increase in the range of 1.4° - 5.8° С Even if we stopped emitting heat-trapping gases immediately, the climate would not stabilize for many decades because the gases we have already released into the atmosphere will stay there for years or even centuries.
