It is reported that half the world’s forests have already been destroyed. This widespread destruction is due to deforestation (采伐森林). Deforestation is the removal of a forest or group of trees where the land is later transformed to a non-forest use. Cutting down trees is necessary for man’s survival. However, deforestation has a number of negative effects on the environment and needs to be controlled.
There are two main purposes for cutting down trees and one of them is to use the trees as resources. Essential items like paper, furniture and charcoal are all made from trees. Deforestation is also carried out to clear land for farming and to make room for roads and houses. As the population grows, more of the forest has to be cleared.
Although deforestation is necessary up to a point, it has some negative effects on the environment. Firstly, cutting down forests destroys animal habitats, leaving them with no place to live in. Deforestation also allows erosion to occur, which leaves the land easy to landslides and makes it difficult for plants to grow there. Finally, the removal of trees also worsens air pollution. Trees act as natural air filters that change carbon dioxide into oxygen. When they are removed, carbon dioxide can build up and pollute the atmosphere. Hence, it is obvious that deforestation harms the environment.
Due to the harm deforestation causes, it is necessary to control it. There are a number of ways to do this. One of them is to make better use of farming land. That means we do not need as much land for farming, and hence do not need to cut down so many trees. There must also be laws to limit deforestation and these laws must be enforced strictly. On top of that, reforestation must be carried out systematically. This method involves planting new trees and plants in areas where deforestation has occurred to replace what was destroyed.
To sum up, although deforestation must be carried out, it can harm the environment and must be controlled. Beyond a certain point, this damage to the environment cannot be fixed. Hence, we should do our best to make sure that the damage is never too great to fix.

【推荐1】The problem of global warming has caused a lot of people to try their best to protect the environment. Unluckily, there are still many people who think it is hard to go green. In fact, it is very easy to be green in our daily life.
You can make a great start by learning to recycle (回收利用). While this looks really simple, there are many people who still throw glass bottles into their common garbage. Almost all cities offer a recycling bin (垃圾箱) for these items. If you put them in the recycling bin instead of throwing them away, you will be on the path to save the earth.
One good thing to recycle is newspaper. But there are still some people who just put their newspaper in the garbage when they finish reading it. As we know, there are many other things we can do with an old newspaper. For example, we can use it to clean our windows.
Another thing that could help you to start to live green is to begin walking a bit more. Many people think nothing of getting in their car and driving one mile to get drinks at the local store. If you walk to the store, not only can it take less time, because you won’t have to try to find a parking place, but you will be saving money on gas and helping to protect the environment. If you wish to save even more on gas, take the opportunity to car pool (拼车) each time you can, which has become popular in many countries.
There really are many means by which people can start living green. They only have to make some changes in their lifestyle to improve our environment.

FrogWatch trainings cover the importance of amphibians in the environment, how monitoring our local frog population helps to protect them, factors to consider in choosing a site to monitor, how to identify frog species by their calls and how to report findings to FrogWatch USA. Become a citizen scientist with FrogWatch USA, and help save our frogs!
Date: Saturday, June 4, 1:00 p.m.—3:00 p.m.
Price: $10household (includes up to 2 adults and 2 children age 8+)
Training instruction:
FrogWatch trainings cover the importance of amphibians in the environment. The instruction focuses on how to:
1. monitor our local frog population to protect the species;
2. determine factors when choosing a site to monitor;
3. recognize frog species by their calls;
4. report findings to FrogWatch USA.
After passing a test on identifying frog calls at the end of the training, certified volunteers then commit themselves to monitoring a local amphibian habitat (such as a pond or lake) approximately once a week for about 15 minutes, and collecting /submitting data on what they hear. Data collected will be added to a national FrogWatch USA database. In 2020, Rhode Island FrogWatch citizen scientists followed 80 sites almost 900 times! In those 900 observations, FrogWatchers, heard more than 1,220 frog choruses.

【推荐3】As an ordinary man, I have a special habit to confess. Whenever I walk down the street, I offer to pour a bottle of water from the nearby river into the dirt of a street tree. It’s just my personal habit, and I think it doesn’t make a difference, but I’d like to do it. I mention this in light of a campaign launched by the Arboricultural Association to call on the public to water new street trees.
The UK government has committed to planting millions of trees to help meet climate targets and aims to increase tree cover from 14.5% to 16.5% by 2050. However, as John Parker, chief executive of the Arboricultural Association, says, “Planting a tree is just the start of the story. The health and survival of new urban trees is threatened by increasingly dry weather. It is recommended that the newly planted trees be given about 50 litres of water per week for the first three years.” While in rural settings, the newly planted trees and woods can take care of themselves and adapt, the challenging conditions mean trees in the urban areas need a bit more care.
Long ago, I assumed that the good of street trees was to soften the hard edges of urban environments. But, what an underestimation of tree power that was! A study from the University of Minnesota Twin Cities illustrates they can provide inspiration or a calming atmosphere in an otherwise crowded city. Trees are responsible for easing urban heat island effects and air and pollutant filtration. And I think they provide the habitat for wildlife, especially birds.
Trees can’t run away. Unfortunately for them and fortunately for urban residents, city trees are stuck with us. If we want to continue enjoying all the good they do, we should try to understand their needs and do all that we can to support them. A bottle of water won’t do much, but next time you all together have a bucket of water to pour, you know what big effect will happen.

【推荐3】Along the coast of Cornwall, the UK, by the white beaches near St Austell, a superhero stands tall. What is this superheroes weapon of choice? She has two, actually: in one hand, a large recycling bag, and in the other, a heavy-duty litter picker.
Meet Pat Smith, the 71-year-old eco-warrior (环境卫士) also known as “Action Granny”. Pat set herself a task to clear the plastic from 52 beaches in Cornwall and Devon. The former teacher jumped into action after watching a film called A Plastic Ocean, which described the range of plastic pollution damaging the world's oceans and killing sea life.
“It was really life-changing for me,” says Pat. “Until that point, I hadn’t realized there was a problem with plastic in the ocean. I went home from the theater and was really bothered. We have been consuming so much plastic that we are causing an ocean crisis. I said to myself ‘I’ve got to do something about it.’”
From January 1 until December 31, 2018, Pat cleaned one beach every week. Yet even with the year over and her task completed, she hasn’t stopped. Pat is also picking up litter — and so are her children in the playground, “My daughter-in-law said last week that she had organize a lifter-picking activity in the playground with other children. That just shows you that when people are exposed to what you do, they are very likely to follow in your footsteps.”
Joining Pat today is Marta, a research fellow at the Basque Center for climate Change, who has travelled from Spain to Cornwall to show support for Pat's action. She also explained her intention of cooperation to Pat. As an environmentalist herself Marta knows how important it is to work hand in hand, and she would like to show her sincerity.
