In today's digital world, especially in Vietnam's vibrant gaming communities like those for PUBG Mobile VN, it's rare to see a real name. Instead, players use pseudonyms and custom avatars. This practice has become a normal part of online interaction. But it raises an important question: are these digital masks just for fun and privacy, or do they allow people to hide from their true selves and responsibilities?

On one hand, using a different name can be a positive and liberating experience. It allows individuals to be creative and explore different parts of their personality without judgment. For many, staying anonymous provides a sense of security, protecting them from unwanted attention and keeping their personal information safe. This digital distance can empower shy people to express their opinions more freely and join communities they might otherwise avoid.

However, this same anonymity can have a dark side. When people believe they cannot be identified, some feel free to engage in negative behaviors like cyberbullying or spreading false information. They might say things they would never say in person. This lack of accountability can turn online spaces from places of fun into environments of conflict. What seems like harmless fun to one person can be deeply hurtful to another, creating a toxic atmosphere.

Ultimately, an online identity is a tool. Whether it is used for creative expression or for causing trouble depends entirely on the user's intentions. It's not the avatar or the fake name that is good or bad, but the actions of the person behind the screen. Being a responsible digital citizen means understanding this power and choosing to use it to build positive communities, not to tear them down.

The idea seemed simple: prevent all wildfires, no matter how small, to protect homes and nature. This policy, however, has had a disastrous, unintended consequence. Naturally occurring, low-intensity fires are essential for a healthy forest ecosystem, (37) __________. By preventing these small fires, fire suppression allowed this 'fuel' to build up for decades.

Now, when a fire does start, often ignited by lightning or human carelessness, it encounters an enormous amount of flammable material. Instead of a small fire that clears the ground, the result is a catastrophic megafire that burns hotter and spreads faster than ever before. These modern wildfires are so intense that they can destroy entire forests, (38) __________. Firefighters find these blazes nearly impossible to control, (39) __________. Therefore, experts now advocate for a new approach called 'prescribed burning,' which involves intentionally setting controlled fires (40) __________. This shift in strategy recognizes that fire, when managed correctly, is not always the enemy.
