Hard Numbers: Coronavirus by the numbers

150: As the Chinese government continues to expand travel restrictions, hoping that reducing human contact will stop the virus from spreading further, at least 150 million people are now facing government restrictions dictating how often they can leave their homes. That's more than 10 percent of the country's total population who are currently on lockdown. Some 760 million are under partial, locally enforced restrictions.

4.5: China's virus containment efforts will have a significant impact on its economy, with first quarter growth potentially slumping to 4.5 percent, down from 6 percent in the previous quarter, according to a Reuters poll of economists. This dip would drag the full-year growth rate down to 5.5 percent, its weakest in three decades.

1.7 million: International airlines have cancelled China service flights accounting for some 1.7 million seats over the past month alone, about 80 percent of total China service. China's aviation market, projected to overtake the US this decade as the world's biggest, has shrunk so much that it's now smaller than Portugal's.

0: Apple has cut its sales expectations for the second quarter of this year, after originally forecasting that it would reap net sales of at least $63 billion, but it has so far given zero indication of what the new forecast will be. The tech giant is highly dependent both on Chinese consumers and on Chinese factories, which are taking longer to reopen and accelerate production than originally anticipated.

How will our cities and lives change in the future? What about a structure with a roller skating rink above a swimming pool, made out of transparent solar panels that power the entire park? This was the innovation invented by Eni's young researchers based on Luminescent Solar Concentrators, developed through Eni's research.

In an interview with GZERO World host Ian Bremmer, Hong Kong lawmaker Dennis Kwok, an outspoken pro-democracy advocate, expresses his concerns that the current "draconian" laws China's leadership is forcing upon his city has expedited the end of the "one country, two systems" policy established in 1997.

For 30 years, citizens of Hong Kong have gathered in Victoria Park on the evening of June 4 to honor the peaceful protesters massacred in Beijing's Tiananmen Square on that date in 1989. It has been the only public Tiananmen commemoration permitted on Chinese soil.

This year, the park was surrounded by barricades to keep people out. The officially stated reason for the shut-down? Crowds spread coronavirus. (In this city of more than 7 million, COVID has so far killed four people.)

Ian Bremmer's Quick Take:

Big news, of course, that former Secretary of Defense Mattis comes out with a public statement basically calling Trump's rule, his actions, unconstitutional and unfit for office, more divisive than any president he's ever seen.
