In sprawling urban centers, often called "concrete jungles," green spaces are scarce. This separation from nature affects our food supply, as most produce travels hundreds of kilometers to reach city markets. However, a global movement is changing this. Urban agriculture, particularly rooftop gardening, is transforming unused city spaces into productive green oases, offering a fresh solution to an old problem.

The benefits of rooftop farming are numerous. Firstly, it provides city residents with access to incredibly fresh, nutritious produce, often harvested just moments before it's eaten. This local production dramatically cuts down on the environmental costs associated with long-distance food transportation. Furthermore, these innovative gardens can become community hubs, bringing neighbors together to share in the work and the harvest, strengthening social bonds.

This trend is gaining popularity in Vietnam. In bustling cities like Da Nang and Ho Chi Minh City, community projects and private companies are helping people set up their own gardens. They move away from conventional farming methods that require large fields and instead use smart systems like hydroponics on rooftops. These local initiatives show that producing food in the city is not just a dream but a practical reality.

While starting a rooftop garden may present challenges, such as initial setup costs and the need for some technical knowledge, the movement continues to grow. For teenagers, it offers a powerful way to reconnect with their food source and understand the environment. It proves that even in a crowded city, a small patch of green on a roof can make a big difference for our plates and our planet.

"Clean coal" technology sounds like an ideal solution to our energy problems, but it's far more complex and costly than its name suggests. The primary goal is to reduce harmful emissions from burning coal, particularly carbon dioxide (CO2). The main method involves carbon capture and storage (CCS), (37) __________. However, this process is extremely expensive and energy-intensive, often reducing a power plant's efficiency.

Furthermore, CCS doesn't address all the environmental issues associated with coal. The mining process itself still devastates landscapes and pollutes water sources. Storing the captured carbon also presents a significant challenge, (38) __________. Critics argue that investing in "clean coal" technology diverts resources away from developing truly renewable energy sources like solar and wind, (39) __________. Therefore, while it aims to make coal less dirty, it isn't a truly "clean" solution, (40) __________.

A. delaying the necessary transition to a genuinely sustainable energy future

B. leaving many environmental problems unsolved

C. which traps CO2 before it enters the atmosphere

D. as there are risks of it leaking back into the atmosphere over time
