10 begins with a look at the politics and the plight of the people of Venezuela.

I'm Carla Zeus.

Thank you for giving us 10 minutes of your Monday.

Part of Venezuela's crisis has to do with its government.

President Nicolas Maduro began a second term as president earlier this year, but the political groups that oppose him say the election he won wasn't free and fair.

President Maduro has said his presidency is truly democratic.

But after his second term began, a Venezuelan lawmaker named Juan Guido, who called his nation's government a dictatorship, declared himself to be the new temporary leader of Venezuela, and other nations began taking sides.

The U.

S Europe and most of the countries around Venezuela have spoken out against President Maduro and in support of Guido, while Bolivia, Cuba and Russia have said they're behind President Maduro.

One thing everyone will be watching for is what happens when self declared leader Guido returns to Venezuela this week.

He's been traveling through South America working to increase support for a peaceful change in Venezuela's leadership.

He's also met with U.

S vice president Mike Pence, while he was in Colombia, but Guido's trip abroad had been banned by Venezuela's Supreme Court.

So the question of whether he'll be arrested when he returns and how people inside and outside Venezuela will react is hanging with heavy tension in the air after important meetings here in Bogota with Vice President Mike Pence, the opposition leader, the self declared interim president of Venezuela want Guido had a stark choice to make was going to stay here and drop international support, effectively a leader in exile or go back to the country, he says.

He's president off.

I asked him what his choice was gonna be when I caught up with him early.

Wrong.

Thank you for your time, sir.

Do you intend to go back to Venezuela this week?

T way?

Yes, we are going to return to Venezuela this week.

We've had a very interesting international gender.

This week.

Three Humanitarian community and COO Qatar.

The meeting off the Lima Group here in Bogota with important results, they were able to see that the crisis is evident but that the regime denies it now.

In that interview, he said that yes, he did fear arrest when he landed on Dhe.

He did fear for his own safety out of his own life, but compared his potential risk to the plight of thousands of Venezuelans every single day, many said, dying from lack of basic medicines.

He also said that if anything happened to him, the price would potentially be too high for the Maduro government to pay.

Still, in the days ahead will learn how he's going to do this on certainly within Maduro's government.

Let him in freely and safely to quote the words in the demand of the US press representative to Venezuelan crisis, Elliot Abrahams.

Now look at how this has impacted Venezuela's people.

Their nation's economy is wrecked.

Critics blame the socialist policies of Venezuela's last two presidents, plus the falling price of oil, which is crucial to the country's revenues.

Inflation is soaring.

Last year, prices on things like food doubled every 19 days.

Venezuelan troops loyal to President Maduro recently blocked truckloads of supplies from entering the country.

Guido says they're needed that Venezuela's food and medicine shortages air getting worse.

President Maduro says there's no crisis in Venezuela and that the supplies are part of the U.

S.

Attempt to overthrow his government.

Still, many Venezuelans are crossing borders to get what they can.

A lifeline crossing, barricaded, formerly closed.

But here, the Colombia Venezuela border is still bustling, and in the distance people seem to be getting across how clashes exactly a week ago closed that border.

It's now almost fortified, but people desperate to get food back to their loved ones inside Venezuela.

What I found Another way down.

We follow the tide is Colombian.

Police stand calmly.

Bye.

These steps of necessity of desperation by people in need of everything endless in number down to the river bank thes don't seem to be steps of just salvation.

Helped as they are at first across the water, past the tree line, we're told, sometimes Venezuelans, soldiers, but mostly gangs who charge for each crossing 50 cents per person on $2 equivalent.

If you're carrying goods, cars and trucks wait for me over there, he says.

It's mostly just guys, not soldiers and faithful recorder.

It's Pessoa.

So they asked for another at it's not soldiers.

I don't know who gets the money.

The dead go back to be buried in their homeland, and the living feel the slow collapse of their homeland.

Bury them and traffic both ways, but with one shared Venezuelan burden.

If you leave, it's more or less empty handed.

Yet those who go back will they do so with pretty much everything they can carry up on the bridge where thousands once crossed daily at the pellets fired last week to keep opposition protesters back.

Who below still carry on with their skirmishes?

Defenses?

The people whose world is measured in varying degrees of nothing and who's suffering here finds only further exploitation.

In which of these countries would you find the Nak Dong River, South Korea, North Korea, Vietnam or Thailand?

Nak Dong is the second longest river in South Korea.

It's found in the southeastern part of the country.

For three months now, firefighters and South Korea have been battling blazes in an unusual place, a giant horseshoe shaped trash pile.

11 years ago, a recycling business owner was given a permit to keep 2000 tons of waste their butt in 2016 residents complained that trash was overtaking the area and the permit was canceled after the site was sold to someone else in 2017.

The previous owner was accused of dumping more than 80 times the amount of garbage allowed at the site.

And the problem, like the trash heap itself, has flared up.

170,000 tons of a legal waste dumped on prime farming Land health risk Andan Isil South Korea is struggling to deal with its own rubbish.

Parkinson has farmed here for 10 years.

Her greenhouses air just meters from the expanding dump.

First of all, there's the dust, she tells me.

The greenhouse is a shell of plastic sheeting.

The dust covers it up blocks.

The light on my eggplants are starting to grow wild.

Since December, the dump is nice, starting to self combust.

As years old Wasti composers.

It produces flammable and toxic gases.

Workers and firefighters doused the fire with water, only to see it reignite elsewhere.

The smell of burning household waste burning plastic construction materials is really quite unpleasant, and this is the wintertime.

It's sub zero temperatures at the moment.

Just imagine what this is like in the summer, one of those who lives very close by so she hasn't opened her windows in the past two years.

The company that owns this dump changed hands just over a year ago, the CEO tells CNN.

The previous owner dumped almost 170,000 tons of mostly illegal mixed waste at market rates that could raise more than $20 million.

We were unable to contact him.

Local officials say he's under investigation.

They first took legal action five years ago to limit him to his original permit of a small storage site for recyclables through government has now had to allocate a budget of $5 million for this, one official tells me, we plan to remove 21,000 tons of waste within the year.

Illegal dumping is happening across the country.

On Beyond this is Mindanao in the Philippines, 6500 tons of waste that a South Korean company had claimed was recyclable plastic synthetic flakes.

In reality, it's filled with batteries, straws, electronic products, used diapers.

After pressure from local environment groups, the South Korean government again had to step in and pay for its repatriation.

China's decision to accept less of the world's waste and unscrupulous companies dumping illegally to make money means South Korea has a new waste reality to deal with.

A dive roller coaster is one that drops at 90 degrees, meaning you're diving straight down as opposed to a less steep downhill angle.

And this is gonna be the tallest, fastest and longest dive coaster in the world.

When it's finished, it's called the Yukon Striker, set to open this spring at Canada's Wonderland theme park.

Its main plunges 245 feet straight down, and its top speed is 80 miles per hour.

So what will be the fallout?

Some will surely fall for it and if your thrilling to strike her out for a wild ride, Yukon, too.

But some will see it and won a roller on by.

If the thought of 90 degrees makes them sweat with their minder stomach getting twisted up her off track or thrown for a loop, they won't want to ride out this dive of a coaster.
