The oldest human footprints in Europe have been discovered in Britain. There are only three other sets of footprints that are older and they are in Africa.
Scientists took digital photographs of the footprints and created a 3D image from them. The images and model were unveiled at a news conference at the British Museum in London. Scientists think that most of the footprints are children’s. There was at least one adult, too.
Discoveries of ancient man’s footprints are extremely rare. Scientists say that the discovery will rewrite our understanding of human occupation of Britain and Europe.
By the end of the year, China expects to lose about one-third of its pigs – 1 million pigs have died so far. There is no vaccine or cure against the disease and once a pig catches it, it is going to die.
Some pig farmers even had to slaughter their healthy pigs to stop the spread of the virus. The virus has already spread to Mongolia, Vietnam and Cambodia where around 95,000 pigs have died.
China is the world’s largest pork producing country, and the massive hit to the pork industry is already creating a ripple effect worldwide. For example, the soy bean market expects to fall because farmers in China will not need as much for pig feed.
In 1990, the average person drank 5.9 litres of pure alcohol per year. In 2017, the number was up to 6.5 litres a year. For 2017, such amount of alcohol is a drink every day. If this trend continues, the average person will drink eight drinks a week.
Not only are people drinking more, more people are drinking, too. Around 45% of people drank in 1990, and 47% of people drank in 2017. This can rise to 50% by 2030.
