Hundreds of years ago, life was harder than it is today. People didn't have modern machines.
Life today has brought new problems. One of the biggest problems is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.
Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog.
Many countries are making rules to fight against pollution. Factories must now clean their water before it is thrown away, and they mustn't let dirty smoke go into the air.
We need to do many other things. We can put waste things in the dustbin and do not throw them on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.
Rules are not enough. Every person must help to fight against pollution.

The only known white giraffe in the world has been fitted with a GPS tracking device in an effort to protect him from poachers (偷猎者) in Kenya. The unique male giraffe now stands alone after a female and her calf were killed by poachers in March, 2020.
The GPS tracking device, secured to one of the animal’s horns, will give hourly updates of his location, said the Ishaqbini Hirola Community Conservancy. Rangers will be able to monitor the giraffe’s movements in the conservancy located in Garissa County, eastern Kenya.
“The giraffe’s living range has been blessed with good rains in the recent past and the abundant vegetation is a good sign for the future of the white male,” said Ahmed Noor, manager of the Ishaqbini Hirola Community Conservancy.
Noor thanked the Kenya Wildlife Service, Save Giraffes Now and the Northern Rangelands Trust (NRT) for their help in safeguarding wildlife species.
“Our mission is to work with communities, secure their livelihoods as well as protect the unique wildlife like the only known white giraffe,” said Antony Wandera, the senior wildlife monitoring officer at the NRT.
The male giraffe has a rare genetic trait called leucism (变白), which results in the partial loss of pigmentation (肤色) in an animal and makes it easy to spot for poachers. Unlike albinism (白化), animals with leucism continue to produce a dark pigment in their soft tissue, meaning the giraffe’s eyes are dark.
In March, 2020, the remains of two of the stunning white giraffes that lived at the Kenyan wildlife reserve were found dead, killed by poachers.
The world’s tallest land animal has lost 40% of its population in just 30 years, the African Wildlife Foundation estimates.

Bees are essential for the pollination of flowers, fruits and vegetables. Sadly, over the past 15 years, the global population of the hardworking insects has been dropping worldwide at alarming rates due to loss of food and habitat. Now, Dutch cities are coming up with creative ideas to help stem the population decrease of these all-important insects.
In Amsterdam, bees can live for free in specially built “hotels” — tall wooden structures — across the city. While they may not look like much to the untrained eye, they provide perfect homes for members of the over 200 known species of solitary bees. As the name indicates, the insects spend their lives alone. The smart insects nest inside holes like the ones provided by the insect hotels, marking their occupancy by covering the entrance with a mud “door”. Though unable to produce honey, solitary bees are excellent pollinators and perform an essential role in many ecosystems.
Additionally, city officials are also educating people on the use of harmful chemicals and are providing prize money to encourage developers to build green roofs and populate them with local plants. In 2015, they set a goal to change some plants in public green spaces to native plants. Geert, one of eight ecologists working for the city, says, “Our idea is when we design a park, we use native species but also the species that give a lot of flowering and fruit for bees.” Many people, with help from the government, are replacing the sidewalks outside their homes with small gardens featuring flowers.
In Utrecht, bus stop roofs are gradually being turned into beautiful, living gardens designed to attract varieties of bee species. The green roofs, which naturally collect both rainwater and dust, are also beneficial for the environment.
These cities’ collective efforts seem to be working. A recent study found that the variety of bee species there has increased by an astonishing 45 percent since 2000.
