Earth, galaxies, the universe. The big questions of life.

I am a big fan of the questions of life, whether on earth (the evolution of life) or the creation of galaxies to see the whole universe. It's still amazing to wonder what's on the distant planets in question. How it all began ? So many questions that may be solved one day.
Many people dream of being rich, but what is wealth without knowing it? Knowledge has always been wealth to me.
There would be 2,000 billion of galaxies ready without counting the billions of planets in each galaxy.

Are we going to be able to visit and colonize habitable planets of the Milky Way? Astronomers have already discovered potentially habitable planets.
Imagine all the beauty that the universe would have to offer us.
Yes many dreams that unfortunately we will never be able to live because of lack of technology. Will our descendants one day be able to achieve the impossible? Unfortunately I have big doubts. The explanation of my fears for our offspring? She is simple! The pollution we are living in our dear land!
Scientists predict global warming in the order of 2 to 5 degrees. Even if they are not suppositions because nothing proves to us that the catastrophe will not be more serious if nothing changes. Unfortunately the actions undertaken by world leaders do not seem to move and worry them more than that.
We are still talking about a catastrophe that will affect all civilization! Yes, in some cases to a lesser extent and others unfortunately in much more serious measures. Increased starvation (we are already unable to help our neighbor who is having problems feeding himself) What will happen if a lot of farmland is burned because of the heat? Not to mention the scarcity of water.
We could do a half-turn at 180 degrees and reduce to almost nothing our pollution but it is not likely to happen given the financial stakes of multinationals but also the change in lifestyle of the population who likes to live in its comfort.
There are still some basic actions that anyone could do.
1: Eat local (go buy in small shops that have short circuits with farmers)
2: Avoid all plastic packaging that causes pollution.
3: Think twice about who you will vote for and decide your future.
4: Do you see rubbish lying on the ground? Pick them up and hop in a trash can!
