Sea salt harvesting is a fascinating process that has been used for thousands of years. The principle is simple: use the sun's energy to evaporate seawater. To do this, workers create large, shallow ponds called salt pans near the coast. (25) __________ of these salt pans are needed to produce a significant quantity of salt. The entire process relies heavily (26) __________ the sun and wind.

First, seawater is channeled into the pans. Then, the sun's heat and the wind work together. This natural process has a profound (27) __________ on the final product. (28) __________, as the water disappears, it leaves behind concentrated brine. Eventually, only pure salt crystals remain. Farmers must carefully (29) __________ changing weather conditions, as unexpected rain can ruin the harvest. If it didn't rain for months, the process would be much easier.

When you enjoy a meal, you probably think about the ingredients, but not the ground they came from. Soil is a vital resource, yet we often overlook its health. Soil degradation, which is the decline in soil quality, is a serious environmental problem affecting the entire planet. This 'invisible' issue directly threatens our ability to grow food, making it a critical concern for global food security and the future of farming everywhere, including in Vietnam.

The causes of soil degradation can be divided into two main categories. There are natural causes, such as erosion from strong winds and heavy rain, which slowly wear away the topsoil. However, human activities are often a much bigger problem. Actions like deforestation (cutting down forests) and intensive farming, where the same crop is grown repeatedly without giving the soil time to recover, significantly accelerate the damage to this precious resource.

In Vietnam, especially in agricultural regions like the Central Highlands, the effects of human activity are clear. The improper use of chemical fertilizers for valuable cash crops like coffee is a major contributor to soil degradation. While these chemicals can boost production in the short term, their overuse makes the soil acidic and less fertile over time. This reduces its ability to support healthy plant growth, creating a long-term problem for local farmers and the nation's agricultural output.

Fortunately, it is not too late to act. Farmers and governments are working on solutions to protect and restore soil health. Sustainable farming methods, such as crop rotation (planting different crops in sequence) and using organic fertilizers instead of chemical ones, can help rebuild soil quality. Initiatives from Vietnam's Ministry of Agriculture and Rural Development also aim to promote these better practices. Protecting the soil is essential for ensuring we can feed future generations.

Virtual internships have become a popular alternative to traditional in-office experiences, especially for young people.
