I am Liu Ying, a high school student. Our school is built 50 years ago. It is very beautifully as you can find many of tall trees, flowers and green grass here. I am very proud of learn in such a school. However, it’s a pity that there is a lot of rubbishes at some corners. I think we can do anything. First, we must know the important of keeping the school clean. Beside, we should spend some time clean up every corner of the school every day. Last, we must remember that no matter where we find rubbish, it is our duty pick it up and put it into rubbish cans.
2 . Would you like to do something to help make our city a better place to live in? Why not take part in “Clean & Green weekend”? Join us, and you can make new friends and help protect the environment at the same time.
Park Life
Do you like playing and relaxing in the park with your friends? If so, why not take the chance to come with us and tidy up the park when you go? To add some fun, there is a gift for the person who collects the most rubbish! Meet us at the south entrance to Taohe Park at 9 a. m. next Saturday if you want to join in.
The Air You Breathe
A great way to make the air we breathe cleaner is by planting lots of trees! It is a fact that trees slowly filter (过滤) a lot of pollutants (污染物) from the air. So come and help us plant some new ones in Fenhe Park at 2 p. m. next Sunday.
War on Graffiti (涂鸦)
Some people think graffiti is cool. Well, it is not! The best way to stop buildings from becoming totally covered in ugly graffiti is to fix it as soon as possible. And that is exactly what we are going to do. We are repainting the school walls from 1 p. m. on Saturday. You don’t have to bring any tools, just remember to wear some old clothes!

3 . Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less usable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(缺乏). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs .
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks(滴水) in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

4 . The populations of common animals are just as likely to rise or fall in number in a time of accelerating global warming as those of rare species, a study suggests.
Until recently, scientists were still accumulating data on how animal populations were shifting over time globally across the different regions of the planet.
Making use of the newly available data, a team of University of Edinburgh researchers studied nearly 10000 animal populations recorded in the Living Planet Database between 1970 and 2014 to provide a new perspective on animal population change. These include records of mammals, reptiles, sharks, fish, birds and amphibians.
The team found that 15 percent of all populations declined during the period, while 18 percent increased and 67 percent showed no significant change. Amphibians were the only group in which population sizes declined, while birds, mammals and reptiles experienced increases. The overall decline in amphibians makes them a priority for conservation efforts, researchers say, as their loss could have knock-on effects in food chains and wider ecosystems.
Gergana Daskalova, of the University of Edinburgh’s School of GeoSciences, who led the study, said, “We often assume that declines in animal numbers are prevalent everywhere. But we found that there are also many species which have increased over the last half of a century, such as those which do well in human-transformed landscapes or those which are the focus of conservation actions.”
Dr. Isla Myers-Smith, also of the School of GeoSciences, who co-authored the study, said, “Only as we bring together data from around the world, can we begin to really understand how global change is influencing the biodiversity of our planet.”

5 . Air travel is growing around the globe, and so is its contribution to climate change. The climate cost of flying has drawn more public attention in recent years, even leading to“ flight shame” in some places, especially for local or avoidable flights.
And while a decline in air travel would help with climate change，flight shame can also be added by other ways that make air travel more environmentally friendly. That includes switching to cleaner，renewable fuel , but as a new study indicates , there's also another, less obvious option: flying at lower altitudes.
In a new study, researchers used computers to predict how adjusting aircraft altitudes might reduce the number of contrails(尾迹)，which we see as white lines across the sky containing black carbon particles (颗粒)，thus reducing their warming effect. The study found that aircraft would only need to adjust their altitudes by about 2 ,000 feet, and since some flights have a larger climate effect than others , only a small part of flights would need to make any adjustments.
Of course flying at a lower altitude might increase flying time and it also means burning significantly more fuel, and thus giving off more CO₂, but the benefits of controlling contrails are worth it.
In addition to changing altitudes，better engine technology could also help control contrails, the researchers add, since black carbon particles are produced by incomplete fuel combustion ( 燃烧). With more efficient engines, aircraft could reportedly reduce their contrail by as much as 70%。Combined with slight altitude adjustment for a small part of flights, this could help reduce overall contrail problems by 90%，the study suggests.
This is promising, but more research i still needed, and it may be a while before improvements like these take effect at a significant scale. So, while it's good to know air travel can have a smaller effect on the climate, for now the best way to achieve that is often by simply staying on the ground whenever possible.

7 . Going green seems to be fad (时尚) for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.
On April 22,2011,we decided to be green every single day for an entire year. This meant doing 365 different things, and it also meant challenging ourselves to go green beyond the easy things. Rather than recycle and reduce our energy, we had to think of 365 different things to do and this was no easy task.
With the idea of going green every single day a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all green things that could be done to help the environment. We wanted to push the message that every little bit helps.
Over the course of Our Green Year, we completely changed our lifestyles. We now shop at organic (有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.
Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planets.
