數十億人隔離在家 科學家發現驚人數據：少了人類，「地球真的變安靜了」
紅包拿來
COVID-19蔓延全球，很多國家採取封鎖令措施，減少民眾外出活動，降低傳播的機率。與此同時，世界各地的動植物反而因為這波人類的厄運，有了喘息復甦的空間，各地頻傳有野生動物跑出來逛大街；而現在甚至也發現，連地殼的振動都相應減弱了。
▼當地球上數十億的人大都留在家中時，想不到連地殼運動的強度也減弱，這對地球這顆品質600萬億噸的星球來說，是相當驚人的。而首先觀察到這個變化的，是比利時的皇家天文台科學家，而尼泊爾的科學家也發覺了地殼運動大幅度的減少。而這樣的變化讓觀測板塊活動的數據變得更加清晰好解讀了，對於預測板塊活動變得更加準確一些。

Hey friends! Am usually not the kind to "surf" on hype, but this time, I think it's for good, what do you think to co-write this? This week :-)

Here is a nice example for the seismic noise reduction owing to lockdown in Nepal. Thanks @seismotom and @wmvanstone for sharing scripts (@SubediShiba1)#seisnepalschool

▼而除了地殼板塊的運動減弱外，野生的動物也頻被捕捉到在原本人群緊密的城鎮中出現，如在英國威爾斯小鎮上，出現過山羊逛大街、啃路邊灌木叢的趣景；或是許久未見的大量海龜，也回到沙灘上產卵繁衍下一代。
I think I just got a group of goats in Llandudno arrested.Let me explain... first, I saw this from inside a dark pub (the one I live in currently). I thought I was seeing things. So I took some video:

One more thing... so we get news alert emails from @Dataminr, like everywhere probably. Helps us find all sorts of peaking news.Never thought my goat tweets would make it into an alert
Framing this one
Goat update: they’re back, and they’re gathering in groups of more than 2

▼而封鎖令的實施後，人類活動減弱下，空氣品質也有顯著的改善，可以明顯感受出空污時的城鎮，和人類活動減少後顯得相當清明的天空之間的差異。

當世界上的人們減少活動之後，反而讓大家發現了更多原本不可思議的奇景，整個地球也都變得更加乾淨、美麗了。
