Today our planet Earth is facing an important problem - the global warming. It occurs because of emissions of toxic gas and increasing greenhouse effect.
Polluting gases are exhausted by factories, cars and other machines. These gases pile up in the atmosphere and don't let the light reflected from Earth's surface get out of atmosphere, which actually causes the warming itself. Because of it, glaciers melt rapidly, the ocean level rises and that poses a flood threat to all islands and seaside countries. It also means an dramatic increase in number of icebergs in oceans, which basically means a threat to sea travellers. Which in its turn poses a threat to economies of a lot of different countries, since most goods are exported and imported by water trade.

Warming is also dangerous for nature since many species of plants and animals are used to live under low-temperature conditions. And if temperature goes up, then certain plants, which are actually food for animals, will die. And that in its turn will make animals starve, and then eventually die as well. And so will die animals, whose food was primarily the previously mentioned animals, and so on and so forth.

I want to live in a country with strong economy, rich flora and fauna and not-overly-hot climate!

Let us save our planet together!

Let us say 'NO' to atmosphere pollution!

Let us switch to alternative sources of energy!

Let's revive our forests!
