Drive less, walk more. Dry clothing outdoors as opposed to in an electrical drier.

Wear shorts in hot weather and consequently use less air-conditioning.

Buy smaller houses or apartments.

Eat mostly vegan food.

And there will be less hurricanes, as less energy released into atmosphere. Those that come will be less severe.

Have a security cable for your laptop too.

They usually have WiFi. Read WiFi policies. Sometimes it is not allowed to participate in online discussions on some topics.

In French a library is une bibliothèque, in German - eine Bibliothek.

Women are abused en mass everywhere, even in the 1st world countries. The consequences of this abuse does not disappear. Probably this is why some women are so aggressive and cruel while driving.

His parents graduated the Moscow State University. It is the best university of the former Soviet Union.

They paid for the education zero, as it was a custom at that time.

Not that the USSR was a fun place, but nevertheless it was not a bad education.

Add to this radiation. There is no magnetic field around Mars.

What is needed for quadrcopters is a small quiet petrol/gas engine. An electric battery has got too little energy. Usually it is just 10 - 30 minutes.

He looked more like operetta singer in this blond wig.

It looks impressive. However there is no good satellite imagery coverage of the whole Earth surface yet. Even though the size of the computer hard disks and digital cameras productivity already allow to do this.

Perhaps. But the space junk is already very serious problem.

Maybe instead of many satellites it would be better to have one powerful robotized HD telescope on the moon. Nowadays the satellite imagery of Earth is not good at all. It is often outdated by years (two weeks is nothing in comparison), sometimes misaligned by hundreds of meters, or nonexistent at all for some areas..

In this case we will know the telescope-digital camera location precisely and the automatic alignment of images to the Earth surface coordinates should be possible.

The Moon is also drifting but it is negligible. Satellites however do require the fuel constantly to stay in more or less precise orbit. Satellites are and always will be temporal poor-man solution.

Satellites' orbits are unstable. They do not carry on board telescopes. I suggest to place on the Moon a large international telescope directed to the Earth.

The distance is not the problem. There are telescopes already which make photos of planets around other stars.

The problem, however, is the clouds and fog. But the telescope-HD camera can make photos of Earth at the areas where the air is clear on that day.

To weeks... I work now on a map of the town with a satellite imagery from 2010. And besides it is offset by about 100 meters at some spots.

Two weeks is fine. Even two months is not that bad.

It means that satellite imagery of more or less good quality exists only for areas where there are a lot of well-to-do users, but not for, say, small towns in remote parts.

Robots can be miniaturized even further. Humans can not.

I mean we use daily maps which are built on satellite imagery 3 - 5 years old. And even this is only in large cities and in industrial countries.

Since the orbit of satellites are unstable the imagery is hard to connect with geographical coordinates precisely.

I do not think humanity can live in space. We on Earth are protected from deadly radiation by the massive iron-nickel rotating planet's kernel.

So let us place the HD telescope-digital camera on the surface of the Moon and direct it not to the remote stars, but the the Earth for a change.
