Greenhouse Airlines
Everyone know, that use airlines is the fastest way to get from Tokyo to New York. But, does anyone thought about how many greenhouse gases is produced by this fly? I will tell you: about 2400 kg of carbon per passenger, round - trip. Thought now air travel is responsible only for about 2% of total greenhouse pollution, this number will increase, and rapidly.
So how then are polluting planes our atmosphere? I tell you: uniquely! The fly in high altitudes, so pollution they create stay up, in skies. They can't fall down, so we can't compensate them (e. g. planting trees). Planes will fly long time on same kerosene fuel, it's impossible (at last now) to change them to fly on electricity. So, what can we do then?
Some people say that we should learn to live more locally and not to travel often with planes. But is this the only option?
Richard Branson spent about $3 billion in fight against global warming. What did he do? Did he planted some trees? No. He advocates having planes towed on the ground rather than taxiing. This way, he could save unspecified portion of fuel on long flights. This was a smart move.
But it won't stop global warming and pollution of our ecosystem anyway. Do you have any ideas, how slow down this process? Please, write them in commentary! ;)

Stereotypes
Stereotype... Everybody know, what is it. Do you remember your childhood? Certainly you watched some cartoons and from the very beginning you knew, who was saint and who was villain. They were like this:

So this are stereotypes.


So this are stereotypes.
A stereotype is a thought that may be adopted about specific types of individuals (skaters), ethnic groups (Jews) or certain ways of doing things (a cop buying donuts), but that belief may or may not accurately reflect reality.
Mostly are stereotypes used to express bad things and there are problems, for example: people from a stereotyped group can't joint other groups, can't succeed in activities, they are judged (even if they try to separate their behaving from a stereotyped group) and many other problems. Often, there are racial prejudices.
But, there are good stereotypes too. In your work, where you know what to do without long thinking how to do it.
Some people try to change other people opinions on stereotypes. There are meeting, where meet two families: one home and one foreign family. This way they try to forget about stereotypes.
What about you? Do you know any stereotypes in your life? Is your life stereotype?
What about you? Do you know any stereotypes in your life? Is your life stereotype?
You can read more about stereotype on Wikipedia websites, or just find it on Google, it's up to you.
Please, leave me a comment and your opinion on stereotypes, I will be pleased.
Btw, this is my first blog, so I hope I made it right :D
