Deforestation is the clearing, destroying, or otherwise removal of trees through deliberate, natural or accidental means. It can occur in any area densely populated by trees and other plant life, but the majority of it is currently happening in the Amazon rainforest. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
Deforestation occurs for a number of reasons, including: farming, mostly cattle due to its quick turn around; and logging for materials and development. It has been happening for thousands of years, arguably since man began converting from hunter/gatherer to agricultural based societies, and required larger, unobstructed tracks of land to accommodate cattle, crops, and housing. It was only after the onset of the modern era that it became an epidemic.
One of the most dangerous and unsettling effects of deforestation is the loss of animal and plant species due to their loss of habitat; not only do we lose those known to us, but also those unknown, potentially an even greater loss. Seventy percent of Earth's land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes. The trees of the rainforest that provide shelter for some species also provide the canopy that regulates the temperature, a necessity for many others. Its removal through deforestation would allow a more drastic temperature variation from day to night, much like a desert, which could prove fatal for current inhabitants.
In addition to the loss of habitat, the lack of trees also allows a greater amount of greenhouse gases to be released into the atmosphere. Presently, the tropical rainforests of South America are responsible for 20% of Earth's oxygen and they are disappearing at a rate of 4 hectares a decade. If these rates are not stopped and reversed, the consequences will become even more severe.
The trees also help control the level of water in the atmosphere by helping to regulate the water cycle. With fewer trees left, due to deforestation, there is less water in the air to be returned to the soil. In turn, this causes dryer soil and the inability to grow crops, an ironic twist when considered against the fact that 80% of deforestation comes from small-scale agriculture and cattle ranching.
Further effects of deforestation include soil erosion and coastal flooding, In addition to their previously mentioned roles, trees also function to retain water and topsoil, which provides the rich nutrients to sustain additional forest life. Without them, the soil erodes and washes away, causing farmers to move on and perpetuate the cycle. The barren land which is left behind in the wake of these unsustainable agricultural practices is then more susceptible to flooding, specifically in coastal regions. Coastal vegetation lessens the impact of waves and winds associated with a storm surge. Without this vegetation, coastal villages are susceptible to damaging floods.
Question 32: The following are negative effects of deforestation, EXCEPT ______ .
A. Myriad flora and fauna species have been eradicated before we discover them.
B. The alteration of temperature in a complete day is becoming more radical due to the loss of trees.
C. The soil is infertile to grow crops because of the shortage of rain and erosion.
D. More and more animals have to find a place of refuge under the canopy of leaves.

Phá rừng là việc phát quang, phá hủy hoặc loại bỏ cây thông qua các biện pháp cố ý, tự nhiên hoặc vô tình. Nó có thể xảy ra ở bất kỳ khu vực nào có mật độ cây cối và các loài thực vật khác đông đúc, nhưng phần lớn hiện nay đang xảy ra ở rừng nhiệt đới Amazon. Việc mất cây cối và các thảm thực vật khác có thể gây ra biến đổi khí hậu, sa mạc hóa, xói mòn đất, ít cây trồng hơn, lũ lụt, tăng lượng khí nhà kính trong khí quyển và một loạt vấn đề đối với người dân bản địa.
Nạn phá rừng xảy ra vì một số lý do, bao gồm: trồng trọt, chủ yếu là chăn nuôi gia súc do tốc độ quay vòng nhanh; và khai thác gỗ để lấy nguyên liệu và phát triển. Nó đã xảy ra hàng nghìn năm, được cho là kể từ khi con người bắt đầu chuyển đổi từ săn bắn/hái lượm sang xã hội dựa vào nông nghiệp và cần những con đường đất rộng hơn, không bị cản trở để chứa gia súc, cây trồng và nhà ở. Chỉ sau khi bắt đầu thời kỳ hiện đại, nó mới trở thành một bệnh dịch.
Một trong những tác động nguy hiểm và đáng lo ngại nhất của nạn phá rừng là mất đi các loài động thực vật do mất môi trường sống; chúng ta không chỉ mất đi những người đã biết mà còn cả những người chưa biết, thậm chí có thể là một mất mát lớn hơn. Bảy mươi phần trăm động vật và thực vật trên cạn trên Trái đất sống trong rừng và nhiều loài không thể sống sót sau nạn phá rừng phá hủy nhà cửa của chúng. Những cây trong rừng nhiệt đới cung cấp nơi trú ẩn cho một số loài cũng cung cấp tán cây điều chỉnh nhiệt độ, một điều cần thiết cho nhiều loài khác. Việc loại bỏ nó thông qua nạn phá rừng sẽ tạo ra sự thay đổi nhiệt độ mạnh mẽ hơn từ ngày sang đêm, giống như sa mạc, có thể gây tử vong cho cư dân hiện tại.
Ngoài việc mất môi trường sống, việc thiếu cây xanh còn khiến một lượng lớn khí nhà kính được thải vào khí quyển. Hiện tại, các khu rừng mưa nhiệt đới ở Nam Mỹ cung cấp 20% lượng oxy cho Trái đất và chúng đang biến mất với tốc độ 4 ha mỗi thập kỷ. Nếu những tỷ lệ này không được dừng lại và đảo ngược thì hậu quả sẽ càng nghiêm trọng hơn.
Cây cối cũng giúp kiểm soát mực nước trong khí quyển bằng cách giúp điều hòa vòng tuần hoàn nước. Với ít cây cối còn lại, do nạn phá rừng, nên có ít nước trong không khí được trả lại cho đất hơn. Đổi lại, điều này khiến đất khô hơn và không thể trồng trọt, một điều trớ trêu khi xem xét thực tế rằng 80% nạn phá rừng là do nông nghiệp quy mô nhỏ và chăn nuôi gia súc.
Các tác động khác của nạn phá rừng bao gồm xói mòn đất và lũ lụt ven biển. Ngoài vai trò đã đề cập trước đó, cây còn có chức năng giữ nước và lớp đất mặt, cung cấp các chất dinh dưỡng phong phú để duy trì thêm đời sống rừng. Không có chúng, đất bị xói mòn và rửa trôi, khiến nông dân phải tiếp tục làm việc và kéo dài chu kỳ. Vùng đất cằn cỗi bị bỏ lại sau các hoạt động nông nghiệp không bền vững này sẽ dễ bị lũ lụt hơn, đặc biệt là ở các vùng ven biển. Thảm thực vật ven biển làm giảm tác động của sóng và gió do nước dâng do bão. Nếu không có thảm thực vật này, các ngôi làng ven biển dễ bị lũ lụt tàn phá.
Câu hỏi 32: Sau đây là những tác động tiêu cực của nạn phá rừng, NGOẠI TRỪ ______.
A. Vô số loài động vật đã bị tiêu diệt trước khi chúng ta phát hiện ra chúng.
B. Sự thay đổi nhiệt độ trong một ngày đang ngày càng trở nên nghiêm trọng hơn do mất đi cây cối.
C. Đất trở nên cằn cỗi không thể canh tác vụ mùa bởi vì thiếu mưa và xói mòn.
D. Ngày càng nhiều động vật phải tìm nơi trú ẩn dưới vòm cây.

Thanks to electricity, candles are no longer a necessity in our lives, but they are still a pleasure. The warm flame of candlelight can quickly alter the mood and atmosphere of a room, often creating a peaceful scene that electric light just cannot match.
Candles are an important part of many cultural and religious festival and have been burnt in various forms for centuries. The ancient Romans and Egyptians made candles from a type of fiber coated with wax. However, up until the nineteenth century, most candles were made from a substance called tallow, obtained from beef fat. Tallow candles were very smoky and, understandably, had an unpleasant odor.
In the 19th century, candle makers learned to separate stearin, the solid form fat used as a type of glue, from tallow and used it to harden other fats. Candles that contained stearin would burn longer than previous ones and had a better smell. Stearin is still one of the main components of modern candle-making, and the techniques used to create candles today are much the same as they have been for many years. These days, the increase range of wax dyes, perfumes and other additives that are now available make candle making a very exciting and rewarding hobby.
Sales of candles have increased greatly over the last few years, showing that they have become part of our lives again, not through necessity, but because of the magical atmosphere they create. In our increasingly stressful lives, the calming quality of candlelight has a relaxing effect that many enjoy.
For those would like to learn to make candles, finding and buying candle-making kits is easy. Candle-making is definitely enhanced by the exciting possibilities of experimentation with various materials. Be brave and try out different effects - some of the most wonderful creations can happen by accident. With a bit of practice, you will be amazed at the very professional finish that can be achieved.
Despite their delicate beauty, candles can, of course, be highly dangerous. One should never leave lit candles unattended, even for a few moments. Always make sure candles are securely placed within candleholders.
Teach your children to respect a burning candle, and of course keep burning candles away from flammable materials. Keep your home safe by remembering that a candle is magical, but fire can be very destructive. Be careful, and enjoy the beauty of your candles!
