1. Cali will have owned a new train that can connect the center of the city with the nearby territories by the year 2030 The project to invest in the new train has been projected since last year but taking into account all the delays due to lack of budget and the pandemic, I predict that this may be a reality and we will have been enjoying this trip by 2030.

As far as I could remember, practicing sports was very unusual activity in adult’s world and they only practiced under doctor prescription, for instance, as a way to control the cholesterol level in blood. But that was all. My parents didn´t used to practice any kind of physical activities and I clearly remember that sports and physical activities were only related with schools and high schools.

If I have to choose a topic, the first thing it comes to my mind is caving.

Caving has been always not just a sport but a passion. A hobby which has to hide sometimes if you do not want people thinks you are nuts. Nevertheless and under my experience, few sports can compete with caving, because is like a pack of adventures and misadventures altogether.

Good or bad, habits have the same origins. They result in very different experiences, of course, but don’t let that color how you think of them.

I can't understand the meaning of the bold part.
Thank you in advance

1. By the year 2021, most of the jobs and schools in Cali will have been using only virtual communication due to the pandemic. Since March of this year, the government made a decree where the population has to live in lockdown due to the coronavirus. From that moment schools and worksites started to require online duties with virtual platforms and virtual meetings.

When I look back many years ago, bet shops did not exist in Spain, and movies were the only places where you could see them. But suddenly they popped up in every single city or town, and nowadays they are widespread all over the country. Moreover, we are no talking just only a new kind of businesses, there are a heated debate among experts about the pros and cons of them.

There was a hungry crow which found a bottle with few water.

FXXK. I can't drink it

The smart crow flew to the river which was far from the bottle. He planned to pick up the stones from the river then put the stones into the bottle. Then he can drink water easily. 
After more than ten times flying. He almost could drink the water finally.
