Humanity is forced to face more and more problems, some of which require quite urgent and very, very difficult solutions. For example, what to do with global warming, which is already having a significant impact on our planet? How to deal with the possible overpopulation of the Earth, what to do if the predictions of the supporters of conspiracy theories come true and a huge asteroid just takes and falls on us? Do not be surprised, but scientists have answers to most of these questions. Here are some extremely ambitious megaprojects that could save the world in due time.
Asteroid killer
We live in a frighteningly huge Universe and nothing can prevent an asteroid from its depths at some point to simply destroy humanity. Something like this has already happened with dinosaurs, and therefore scientists are constantly trying to figure out what to do with this threat. One of the most promising solutions involves the development of a special spacecraft, an asteroid killer. He will be able to intercept dangerous aliens while approaching the planet and knock them off course. A little less effective than was shown in "Armageddon", but much more effective.
Doomsday Lunar Vault
In 2015, the Global Seed Bank was established in Svalbard. Most of the most important seeds for humanity are stored here, under extremely reliable protection. But will this be enough in the event of a disaster? Definitely not. Bernard Foin, lead researcher of the ESA SMART-1 mission, is leading a project to transfer genetic information from people and animals to the moon: according to his idea, even if the Earth dies, the survivors will have enough time to restore culture on another planet. At the moment, the storage probe is being developed by Foin together with NASA scientists.

Control over the sun
In 1992, Russia implemented a very ambitious project "Banner 2" - a kind of space mirror designed to reflect the sun's rays at certain places on the planet. The idea of solar reflectors has since gone through a real renaissance: now many European countries are working on suborbital light satellites that will be equipped with solar sails. The implementation of these projects could solve the problem of energy shortages once and for all, since conventional solar panels will become a very efficient source.
World house
According to the United Nations, more than 11 billion people will live on Earth by 2100. No one yet understands whether the planet will be able to feed such a large number of people, but scientists are trying to address this issue. One of the most ambitious projects is the creation of a vertical super-city - such towers are planned (of course, in the boundless future) to be built over deserts and poles. Each such tower will be able to accommodate 500,000 million people … Such a number simply does not fit in the head.
