The stage is set for a major commemoration of a significant anniversary.

That's our first story today on CNN.

10 on Coral Jesus.

Welcome to the show, the first of October mark 70 years since the People's Republic of China was established.

That's the country's official name under the communist government that was formed in 1949 though China itself has existed for thousands of years despite the term People's Republic.

The Asian countries actually the largest communist state on Earth and the celebrate its founding is a communist country.

The Chinese government is holding a massive military parade through the nation's capital.

It's expected to include 15,000 members of the armed forces.

More than 160 planes, hundreds of weapons all on display in the center of Beijing.

Security's been increased, Tourists say police are everywhere.

Roads have been blocked off a major subway, lines been shut down, drones and kites have been banned, and residents say there have been more restrictions on Internet use in Beijing, with sites like Google, Facebook and Twitter almost impossible to use.

China's government controls the media as well as the nation's politics and it wants to ensure nothing goes wrong.

During the parade.

Ahead of the event, Chinese President Xi Jinping called for unity among China's people.

One area the government's keeping a close eye on is Hong Kong.

There been protests for 17 weekends in a row in the Special Administrative Region of China.

Most demonstrators there have been pushing for more democracy for Hong Kong, and some protests have been violent, with civilians throwing gasoline bombs and bricks at police and setting fires and police firing tear gas at the protesters, as well as warning shots and blue dye from water cannons.

That's intended to make the demonstrators easier for police to identify later.

China insists it has ultimate control over what happens in Hong Kong, and the Reuters news agency says China has increased the number of its troops in the city.

They may be standing by in case protests well up during China's 70th anniversary celebrations across the Pacific.

The United States is more than a year and a month away from its next presidential election, but a lot has already happened Among dozens of candidates, for instance, seven Democrats have dropped out of the race and 19 are still in it.

Their party has already seen several debates, and though none are scheduled for Republicans, there are three candidates challenging President Donald Trump for the GOP nomination, though analysts have said they're unlikely to defeat the incumbent president.

Still, how does the U.

S get from 19 candidates on the Democratic side to the one whose name actually appears on the ballot?

That's decided through primaries and caucuses, which start early next year?

American politics is dominated by two parties, Republicans and Democrats.

That means only two people have any real chance in the presidential election every four years.

If you want to help decide who those two candidates are, the primaries are your best chance.

The idea of actual voters participating in the primary process.

It's relatively recent, as in New Hampshire, didn't put candidate names on primary ballots until 1948 and those results weren't binding until 1952.

It used to be that presidential candidates were selected at party conventions.

It was mostly party members who selected delegates who went on to a convention to vote.

Convention's still happen, but they're mostly ceremonial.

Since primaries have determined every candidate for more than 50 years.

Here's where it gets confusing.

Every state conducts their own primaries, and none of them do it exactly the same.

They're spread over the course of months in a presidential election year, which why candidates set up camp in early voting states like Iowa, New Hampshire, South Carolina and Nevada.

If a candidate banks on Iowa and doesn't win there, they might have to drop out.

Democrat Martin O'Malley suspending his campaign tonight.

A surprising finish in New Hampshire can make a candidate blow up, on the other hand and give him new Momenta.

Tonight, we sure showed them what a comeback looks like.

Some states, like Iowa, have caucuses, which are more like neighborhood meetings than a traditional primary.

People show up and actually lobby for their candidates.

Some states have open primaries, meaning anyone can take part in the primary, even if they aren't registered party members.

Other states have closed primaries, meaning you have to join the party in order to vote.

And some states, like California, are experimenting with completely non partisan primaries.

Although not at the presidential level, the primary system has continued to evolve.

After Bernie Sanders lost to Hillary Clinton in 2016 his supporters complained about the influence of party bigwigs tipping the scales.

The Democrats have changed the rules for 2020 and given primary voters a stronger voice.

Which of these cities is located along India's Arabian Sea coast, New Delhi, Mumbai, Bangle LaRue or Kolkata On India's west coast, you'll find Mumbai, a city with almost 20 million pollution, and overpopulation are two of the challenges India has struggled with and combined.

They created the perfect storm of garbage along a beach in Mumbai.

It wasn't just because the local population was using verse of a beach as a dump.

A lot of the trash was floating down creeks from other communities.

The cleanup effort was started by a man who couldn't take it anymore.

This is not a landfill.

Tha This was verse of a beach in Mumbai, India, A little over three years ago, it was covered in over 6000 tons of trash.

After what the United Nations called the world's largest beach cleanup.

This is versatile beach.

Today it was the movement started and led by one man Afros shop.

My name is a rush on a lawyer by profession, and I love oceans in October of 2015 verse of a beach was little more than a dumping ground on the west coast of Mumbai.

There were five and 1/2 feet off plastic.

And when you say so much past injectables to the ocean, it's scary.

It's very scary.

Way have devastated the health of the ocean Garbage.

I elope, their own land or a notion, is a big issue.

Not only in their world or so Afros took matters into his own hands.

He started picking up the trash himself.

I have spent my childhood here, you know.

I used to play her on the beaches to very, very clean for me, for security simple.

It had to be my personal journey.

Then, I told myself, will be difficult for a single man to do it.

So I said might not take this personal journey to others.

I provoked us to join in and eventually did journey since 2015.

Every weekend, hundreds of volunteers joined Afros to pick up the trash that has been strewn along the two mile stretch of the beach, and the volunteer work continues.

Today we have been cleaning for past 112 weeks now, and it's almost nine million cages off plastic and filled out from Ocean Beach.

Cleaning is one of the biggest preventive action to prevent this plastic going into the deep sea.

This is minimum.

We can go through the use of trucks, bulldozers, buckets, whatever people can use.

Beach has slowly been picked up, but the issue is more than just the beach.

It's about the mindset of people.

So apart from the beach cleanup, Afros also works with local communities to help educate them on recycling and proper trash disposal.

We go toe coastal communities where you know the lecturing happens.

Talking to them, I go to people's garbage, I tell them.

Show me, then I'll tell them how to segregate howto handle plastic.

This is the first Greek which is entering into the ocean.

From here.

I'm proud that I'm connecting with people and I'm correct.

Intimated that gets a very big sense of pride in my heart.

You know, this problem of pollution is created by us.

The lost a sense of belonging to the Iron Planet into the ocean.

A lot of people ask me offers how long you're gonna clean the day we see that this ocean is mine and it has to be *** and span.

Well, not as this question.

In fact, we'll go on a problem that has to do what I'm doing.

We're in for a long haul on every citizen in this pan months being for long, doing a bit for 10 out of 10.

Why sit around like a bump on a log when you can roll one under your feet across the Mississippi River?

That's what Elissa Weatherby thought, and last Thursday, the professional Timber sports athlete did it rolling and floating on a synthetic log from Port Byron, Illinois.

Toe.

Leclaire, Iowa.

Whether B is said to be the first person ever to do this, and her husband says she's a great role model, we may not know how much wood would a woodchuck log if a woodchuck would log roll.
