The desert is one of the most challenging environments on Earth. With its harsh sun and little water, survival is difficult. However, one animal, the camel, is famous for its ability to live in these conditions. How (35) __________ this animal thrive where so many others cannot? The camel has a series of amazing physical adaptations that allow it to journey across vast sandy landscapes.

A camel’s most (36) __________ feature is its hump. Many people mistakenly believe the hump stores water, but it is actually a large deposit of fat. When food is scarce, the camel's body can convert this fat into the energy it needs to survive. (37) __________, along with its ability to drink large amounts of water at once, means it can go for long periods without eating or drinking.

To protect itself from sandstorms, a camel has very long eyelashes. These act like a screen to (38) __________ protection for its eyes. In fact, their eyelashes are often much (39) __________ than those of other animals. Furthermore, a camel is able to close its nostrils completely to prevent sand from getting into its nose during a storm.

Camels are also well-equipped for walking on soft sand. Their feet are (40) __________ designed with two large toes that spread out, creating a wide surface area. (41) __________ do their feet prevent them from sinking into the sand, but they also have tough, leathery pads to protect them from the hot ground. This unique foot structure makes them incredibly efficient at moving across deserts.

(42) __________, the camel is a masterpiece of natural engineering. From its fat-storing hump and protective eyelashes to its specialized feet, every part of the camel's body is perfectly suited for its desert home. These adaptations are the reason why it has earned the title 'the ship of the desert.'

Have you ever looked at the uneaten food on your plate after a family dinner or in the school canteen and wondered where it goes? While a little leftover rice might seem harmless, it is part of a much larger, global issue: food waste. Astonishingly, around one-third of all food produced for human consumption worldwide is lost or wasted every year. This isn't just about throwing away food; it's about squandering the valuable resources used to produce it and causing serious environmental harm.

The journey of wasted food often ends in a landfill, and this is where the real trouble begins. When food decomposes in a landfill, buried under tons of other trash, it does so without oxygen. This process releases methane, a greenhouse gas that is over 25 times more potent than carbon dioxide at trapping heat in the atmosphere. The environmental impact is therefore significant. Furthermore, every time we waste food, we also waste the water, land, and energy that were used to grow, process, and transport it. The problem is far bigger than just our leftovers.

In Vietnam, this global issue has a distinct local dimension. Food waste becomes particularly noticeable during large celebrations, especially the Tết holiday. The tradition of preparing an abundance of food to show hospitality and hope for a prosperous new year often results in large quantities of leftovers. Recognizing this challenge, social campaigns and organizations like Food Bank Vietnam are working to raise awareness. They aim to rescue surplus food and redistribute it to those in need, turning a problem into a valuable solution.

Fortunately, tackling food waste doesn't require complex, large-scale solutions alone; individual actions can make a huge difference. As teenagers, you hold more power than you might think. Simple habits like planning meals with your family to buy only what you need can prevent waste from the start. Being creative with leftovers—turning last night's chicken into today's noodle soup, for instance—is another effective strategy. Additionally, understanding the difference between “use by” dates (for safety) and “best before” dates (for quality) can stop you from throwing away perfectly good food.

Ultimately, the path from our plates to the landfill is one we can change. By becoming more mindful consumers and making small adjustments to our daily routines, we can collectively reduce the environmental burden of food waste. Every meal saved is a small victory for our planet, proving that even simple choices can lead to a more sustainable future.
