1. Global warming is one of the biggest threats humans face in the 21 century.

What problems are associated with this and what solutions can you suggest?
Climate change is the greatest threat to humanity this century, and ocean levels are rising at an alarming rate. There are other issues associated with this; however, I believe that there might be serious issues, which is residential flooding, as well as potential solutions.

To summarize, while it is true that ocean levels are increasing as a result of global warming, flood-prevention strategies could serve to alleviate the suffering. Many countries, including Sri Lanka, must employ flood-prevention strategies to protect their citizens from disaster.

2. Global warming is one of the biggest threats humans face in the 21 century.
What are the main causes and what problems are associated with this?
One of the most pressing issues confronting humanity is the threat posed by increasing sea levels, which is one of the consequences of global warming. Flooding, the loss of coastal land, and mass migration from these places are all concerns that arise as a result of this. However, there are options for resolving this issue.

To sum up, the threat of increasing sea levels to humanity cannot be overstated. This issue must be resolved immediately. If I were the government, I would construct sea barriers to safeguard the most vulnerable locations and develop international alliances to limit carbon emissions. This would mitigate the effects of global warming, which is the root of all of this.

3. Today more people are traveling than ever before.
Why is this the case?
What are the benefits of traveling for a traveler?

Globalization and technological advancements have made our lives easier than they have ever been. In today's world, more people want to spend their leisure time traveling and on vacations. However, I absolutely believe that, as a result of more facilities, improved transportation, and other chances, people presently travel more than they did in the past.

In conclusion, given all of the causes and benefits of traveling, individuals are becoming increasingly interested in doing so. Globalisation, new technology, and inventions make everyone's life easier, allowing them to travel whenever and wherever they want.
