FUTURE PERFECT

> will have +participe passé

FUTURE CONTINUOUS

> will be + V-ing

By 2050, I don't think people will have travelled to Mars.

However, I think they will have settled in Space. Some people will be living in space stations, because the Earth will be too crowded.

I think scientists will have built huge farm in space in special glass buildings, and they will be developping a very healthy diet for people.

People will be eating specially developed fruit and vegetables.
