    Blue Planet II's latest episode focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastic.

    Though it seems now that the world couldn't possibly function without plastics, consumer plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s; the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.

    We put all these plastics into the environment and we still don't really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.

    And it's not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don't have to remake our planet energy system.

This is not a problem where we don't know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to dispose (处理) of it. We know how to recycle. We can all start by thinking twice before we use single—use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag—when taken collectively, these choices really do make a difference.

    While elephants born without tusks (长牙)are not unheard of，they normally form just 2 to 6 percent of the population. However, that is not the case at Mozambique's Gorongosa National Park, where an astonishing 33 percent of female elephants born after the country's civil war ended in 1992 are tuskless. While that may appear to be just a coincidence, Joyce Poole, an elephant behavior expert, has another theory. The researcher thinks we may be witnessing unnatural evolution of the species due to the constant hunting of elephants for valuable ivory.

    Poole says before the country's 15-year-long civil war, the 100,000—acre park was home to over 4,000 elephants. However, by the time the conflict ended in 1992, about 90 percent of them had been killed for ivory to help finance weapons (武器)and meat to feed the soldiers. Of the less than 200 survivors, over 50 percent of adult females had no tusks. Therefore, it is not surprising that the park's tuskless elephant population has grown greatly.

    This is not the first time researchers have observed a great change in the population of elephants. At Zambia's South Luangwa National Park and Lupande Game Management Area ， areas which were heavily hunted in the 1970s and 1980s, 35% of elephants 25 years or older and 13% of those younger than 25 are now without tusks. A 2008 study published in the African Journal of Ecology found that the numter of tuskless females at the Ruaha National Park in Tanzania went from 10.5 percent in 1969 to almost 40 percent in 1989, largely due to illegal hunting for ivory.

    The recent ban on ivory in both the US and China should help get rid of, or at least reduce, elephant hunting. However, scientists are not sure how long it will take for elephants with a higher rate of tuskless females, to change the trend.

    Have you ever been to a music festival? Well if you live in the UK, the answer is probably yes. The number of festivals has grown greatly over the last few years and now there are around 200 every summer. So let's look at the history of four famous festivals.

    The Glastonbury Festival is a five-day festival of contemporary (当代的) performing arts held most years in Somerset, in the south-west of England. There are a rock and pop stage, a jazz stage, the Avalon stage, a theatre comedy stage, a cinema tent, a dance tent and a circus (马戏团). The festival started in1970and about 120, 000 people go to it every summer.

    The Reading Festival is truly world-class with rock and pop bands (乐队) appearing from all over the world, particularly (尤其) the USA. About 80, 000 music fans go to Reading every August Bank Holiday. The festival first came to its present site on the banks of the River Thames in Reading in 1971, when it moved from Plumpton in Sussex. It is still on the same site over 47 years later!

    WOMAD stands for World of Music, Arts and Dance and was the idea of rock musician Peter Gabriel to promote (宣传) world music. The WOMAD Festival started in 1982 and takes place in July at Charlton Park, near Malmesbury in Wiltshire, and you can see different bands and musicians from all over the world. The festival welcomes over 26, 000 visitors each year.

    The one-day Monsters of Rock Festival at the National Bowl in Milton Keynes was first held in 1980 and gave visitors the chance to hear the very best of hard rock and heavy metal. There were no festivals between 1996 and 2003 as a result of changing musical fashions, but now it has returned and grown into a two-day festival with a campsite for the 30, 000 people who go there in summer days.

    In earliest times, men considered lightning to be one of the great mysteries (神秘的事物)of nature. Some ancient peoples believed that lightning and thunder were the weapons (武器) of the gods.

    In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs (灯泡).

    The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device (装置物) protects buildings from being damaged by lightning.

    Modern science has discovered that one stroke (闪击) of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.

    Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average (平均数) of one person every day.

    The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.

    With lightning, it is better to be safe than sorry?
