Haze(雾霾)is a kind of air pollution in which the air is filled with dust and smoke. Haze stops people from breathing and seeing things clearly.
This kind of pollution comes from all kinds of sources, especially natural and man-made sources.
Haze has done great harm to our daily life. For example,
People have realized the great harm caused by the smoke and the importance of protecting the environment.
Besides, we should pull together to plant more trees to improve the environment.

A Meaningful Tree-planting Day
__________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________3 . Our carbon footprint is the estimated amount of carbon dioxide (CO2) given off as we go about our daily lives. While the global average carbon footprint is about 4 tons per person each year, Americans contribute approximately 20 tons of greenhouse gas per person each year. Compared to other countries, even those who use the least amount of energy in the US still contribute double the carbon emissions than the global average per person. And, not surprisingly, a person’s carbon footprint increases in size as his or her income increases.
How is it possible that people in the US who live simple lifestyles, e.g., children or the homeless, make such large contributions to greenhouse gas emissions? The answer is simple: Each US citizen has access to various basic government services such as firefighting and police departments, road and bridge repair, libraries, jails and prisons, the military, etc. When these public services are divided equally among the entire US population, it significantly raises the carbon footprint per person. In fact, according to a study conducted by the Massachusetts Institute of Technology, the lowest carbon footprint that can be calculated for a person living in the US is 8.5 tons. And shockingly, this carbon footprint corresponds to a homeless person who sleeps in public shelters and eats in soup kitchens.
While it is admirable to make changes in lifestyle to reduce a carbon footprint, in reality, it is very difficult to do. The MIT study revealed that a “rebound effect” occurred when someone made an effort to reduce his or her carbon footprint. Take the example of a person who made the deliberate choice to buy a hybrid car instead of a large SUV to save money on gas costs. Very often that person would use the money he or she saved to do something else, e.g., take a long airplane trip. In this case, just one long airplane trip produces more CO2 emissions than driving the large SUV for a year. This ends up having a negative impact on a person’s carbon footprint by making it bigger!
Can Americans reduce their carbon footprints? According to the study, it is possible, but it would require lifestyle changes such as giving up long-distance travel and buying fewer smartphones, tablets, and MP3 players that have large energy costs to produce and deliver. Another way to lower the average Americans US carbon footprint is to add a CO2 tax on food, housing, and transportation, and most Americans don’t want their taxes raised. Unless we can find a way to reduce our carbon footprints, the price we may ultimately have to pay is much higher than the amount Americans will ever have to pay in taxes.

Melati and Isabel deeply love their home on the island, surrounded by tropical rain forests, green fields, and a vast ocean. Enjoying a swim at their local beach was once a daily pleasure for them. But when Melati was fifteen, and Isabel just ten, the sisters started to lose their enthusiasm for swimming in the waters near their borne. More often than not, plastic bags would be around them as they swam and some were scattered on the beach. They got really upset about that.
Melati didn’t think much about it until one day her teacher gave a lesson on some world heroes. Each of those people had sparked movements of positive changes in the world. They believed in the impact they could have and they did inspire more people to do something meaningful. After school, Melati walked home slowly in silence, concerned about the vast amount of plastic rubbish on the beach. The heroes crossed her mind. If they could do it, we could do it too, she thought. The idea lit her up. She couldn’t wait to share what she thought with Isabel and quickened her pace.
“So many plastic bags around! The beach is dirty and messy! It’s so terrible! We have lost the clean and beautiful beach. Can’t we do something to get it back?" Melati said heartily. Isabel felt a bit puzzled at what to do, but she also had a strong desire to do something. Picturing a beach as fascinating as before in mind, the pair jumped with joy.
They talked a lot, anxious to know how Dad and Mom would respond to their ideas. That night when the family sat by the dinner table, the sisters eagerly got their ideas across. While Mom and Dad listened to the girls carefully, their eyes shone. “How amazing that would be! We are so proud of you!” Dad exclaimed. Mom came up, gave them a thumb up and hugged the sisters.

A previously unlit cycle path in the Netherlands has recently drawn our attention. It has been resurfaced with a material that consists of thousands of shining stones in order to create a well-lit route. The Van Gogh Path, so called after the artist who lived in the town of Nuenen in 1883, combines the traditional with the contemporary in a gesture that acknowledge ledges Van Gingh’ masterpiece The Starry Night, but also shows the way ahead for city lighting. The Van Gogh Path is not a single case; it is not difficult to foresee a time when natural materials could help light the cities of the future.
Why should we care about city lighting? What’s wrong with current electrical city lighting anyway? Well, the problem that it causes is two-fold. First, of course, electrical lighting in most cities comes from non-renewable resources. According to the International Energy Agency, almost 20% of global electricity is consumed for lighting, which is responsible for high levels of carbon emissions. But there’s also the belief that electrical light itself is a form of pollution by destroying our view of the night sky.
From the above reasons, then, it seems wise to investigate other approaches. The city of Glasgow is attempting to use intelligent street lighting to monitor how citizens interact with the urban landscape and minimize electrical consumption and thus emissions. This “Smart City approach” is seen by many as the way of the future, but some designers aren’t convinced. They are pioneering the altogether more original approach of using materials from the natural world in order to replace electrical light entirely. They believe that this new “technology” can one day completely replace microchips and digital systems as we find better ways of making use of the light-producing mechanisms (制) that already exist in the natural world.

9 . On December 16, 2023, the first section of Maya Train officially opened, which runs between Campeche and Cancún, carrying up to 231 passengers across 290 miles and stopping at 14 train stations.
Built as an ambitious effort to promote tourism and boost Mexico’s economy, the rail system connects the major cities and tourist regions of the Yucatán Peninsula —from Cancún’s beaches to Tulum’s archaeological wonders. Once the project is completed, the entire rail system will link tourist destinations across five states. However, environmentalists and archaeologists argue that the train route will cause great damage to the environment-and ancient Mayan sites.
The Maya Train passes through six UNESCO World Heritage sites and thousands of archaeological sites. One particular area of concern is the Calakmul biosphere reserve, which is home to many endangered species, such as jaguars and over 500 other animal species. The train lines, more than 60 meters wide, could act as artificial barriers that may limit the movement of these animals within the reserve making it difficult for them to move around and access food and water sources.
Opponents also express safety concerns. Certain sections of the rail system will be built right on top of the aquifer’s(含水层的) most fragile points of contact with the surface. “It’s like wanting to build over eggshells,” says Guillermo Christy, a water treatment consultant. “Putting trains weighing thousands of tons on top could cause the underground caves to crash down.” To construct the train infrastructure also requires driving long piles deep into the ground, which poses a big threat to this fragile ecosystem and leads to water shortages.
In the ongoing debate of Maya Train, it is crucial to consider the delicate balance between economic development and environmental preservation. While Maya Train may provide economic benefits, we must not overlook the potential environmental and cultural losses, as well as the safety risks it may bring. Achieving harmony between progress and conservation may be a significant challenge for the project, but we must take into account the long-term consequences of our actions.

Time for a clean-up
You are probably aware of the term “forever chemicals”, if not entirely clear on the specifics. What they are is a class of around 16, 000 artificial compounds called PFAS that break down very slowly, if at all in the environment and our bodies. They are extremely useful, but also a potential
