  Whether the global economy can recover from the new crown pneumonia epidemic will depend heavily on whether the new crown vaccine can be successfully promoted.
  -At the beginning of 2021, the World Bank predicts that the global G DP will increase by 4% in 2021. However, if vaccination is delayed due to logistics problems and people’s resistance, then the global GDP may only increase by 1.6% in 2021.

When Chase Bank reduced its ad display from 400,000 websites to 5,000 websites, it found no change in business results. When Uber gave up $120 million in advertising spending, it found no change in app install rates. When big brands reduce their spending on digital advertising, nothing happens.

He believes that although the epidemic has almost brought tourism and economic activities to a standstill, the reduction in greenhouse gas emissions has not yet reached a level sufficient to avoid the worst consequences. Therefore, mankind still needs more innovative measures to prevent death, damage and destruction caused by global warming.
