Problems such as unorganized mass tourism has existed for years now. Bringing the beautiful landscape to face the fate of tourist vandalisation. Causing massive harm to the scenery, however, this issue would only be further enhanced by the consequences of overcrowding. Thousands of people from both in and out of nation continuously flocking the area, resulting in the heritage site being extremely damaged. The issue of illegal commercial also get brought up frequently, harming the reputation of the site and staining its historical values.

Therefore, in 2023. After enduring the COVID-19 pandemic, several plans has been set in motion to resolve the issues within the Trang An heritage site. More detailed tourism plans, along with upgrades regarding the waste water system has been in the work. Progress of natural and cultural preservation would be observed carefully. Long-term plans regarding the effect of pollution and waste would be in the making, people from both governmental agencies and the local community would join forces. Making sure the awareness of environmental damage be acknowledged by the people, pushing and motivating tourists to take action. Cleaning after themselves and leaving no waste or carbon footseps behind their trail. The issue of false advertisement would've already been reduced, leaving no threat to the site's reputation and history.

With the determination and work ethic of the people. Trang An heritage site will have its natural beauty restored and observed by many as the cultural legacy as it has been for decades.

first of all the river is suffering from environmental pollution and global warming.

The river is littered by people.moreover garbage factories regularly dump garbage into rivers and turn the river into a garbage pit thereby causing the river to become heavily polluted.

Secondly, because of the prolonged drought in Vietnam in the summer, the water volume of the river has been significantly drained.However, this phenomenon has also been partially overcome because rainfall gradually stabilizes in Vietnam.

in my opinion, althought the problem is very serious but there are many solution to this problem. we can raise aware of people to realize the serious of this problem. beside we can plant more tree, propagate for more people to propaganda so that people don't do things that affect the environment and the river.

in conculusion red river is very important from livestock farming to Vietnam's maritime trade so we need Preservation and conservation of the river

Tourism combined with environmental protection;

Preserving, repairing and restoring monuments, propagandizing and educating to raise people's sense of responsibility. but people's awareness is always the most important. Hoi An is characterized as a city with world cultural heritage, so Hoi An's general development orientation needs to be in harmony with heritage conservation, Use heritage as a foundation for development. So

Some solutions for spatial development to protect Hoi An city from the risk of urbanization, towards sustainable development: For the old town: Maintain the architectural form and structure of the old town and its surrounding areas. relics; Conservation promotes heritage value on the basis of ensuring the preservation of the originality of the monument; Find ancient documents about trading, trading, and commercial activities to rebuild the image of the old town, thereby bringing back the true emotions and images of the old Cang Thi city; Limit the commercialization of the old town. For areas outside the old town: Establish a safe buffer zone for the old town: including the Hoai River bank, fields surrounding the old town, this buffer area has the effect of both protecting protect the old town against encroachment and restore the original space of the old town in the past; Have a plan to prevent encroachment through the buffer zone. Citywide space: Develop a plan to orient the development of city space to become a green urban area - an ecological urban area with the criteria of "street in a garden - garden in Reasonable, flexible, and sustainable spatial layout for the city's development factors.

Firstly, Halong Bay is a beautiful beach, so it is inevitable that many tourists visit this place and litter indiscriminately on the beach. This causes Ha Long beach to become worse and worse and more polluted, greatly affecting the ecosystem in Halong Bay. Moreover, Ha Long Bay also faces devastation from industrial parks, food services, and coastal restaurants. Industrial parks and coastal shops are constantly discharging untreated waste into the sea. This causes the water source to become seriously polluted. Halong Bay will gradually lose its own value, causing fewer tourists and therefore the economy of the city also became diminished.

On the other hand, there are some solutions to address these negative problems. First, travelers must raise their awareness of the importance of protecting the marine environment, not littering the beach. Ha Long Beach will become greener and more beautiful when carefully preserved Ha Long beach will become greener and more beautiful when carefully kept. Futhermore, industrial parks and shops are not allowed to discharge wastewater into the water environment to make the water greener and protect the ecosystem of marine animals. Finally, the government should also introduce penalties for littering on beaches and discharging sewage into the sea, such as fines for public service for littering indiscriminately and heavy fines for cases of dumping wastewater into the marine environment. It is heavy for cases of discharge of wastewater into the marine environment.

In conclusion, there are some significant solutions to solve problems that Halong Bay faces such as: raising awareness of the importance of environmental pollution, industrial parks, and restaurants are not allowed to discharge wastewater into the water environment, and the last solution is penalties from the government to punish violations.

First of all, those cultural relics face time. Over time, those relics are no longer intact, the colors as well as the details inside are no longer as complete as before, which will affect the experience of tourists as well as affect our image to the world. Next, climate change as well as the high number of tourists will cause the monuments to deteriorate, the change of climate causes its materials to change, which can be dangerous for tourists. From there, the number of tourists will decrease, partly affecting revenue, partly affecting the economy of Vietnam.

To overcome these problems, our State needs to strengthen the renovation, renovate the internal equipment to keep the structure intact of the monument, in addition to strengthening security forces to blame tourists for touching ancient relics that affect the relics. The state needs more ways to preserve relics due to the influence of weather.

In conclusion, in order to preserve cultural relics, we need the support of the State as well as the awareness of tourists to be able to protect relics from problems in today's life

To begin with, each years in here welcome a very large number of visitors and so make air pollution and make overload. Many vehical come to Hoi An and emssion a lot Co2 in here so that make asmotphere in here very toxic and also some visitors have low awreness they littering into river make water pollution. Futhermore overload is also a main idea make heritage Hoi An downgraded. They come so overcrowding restoration work for legacy sites does not have time to complete.So that the situation in Hoi An is very dangerous

However, goverment also awreness this situation and they also offer some rules to protect Hoi An from downgraded. First of all, they will punish visitors who littering in there to warning them. Futhermore, limited time for visitors come heritage to preserve heritage avoid to downgraded.For example, goverment limited time to preserve heritage, heritage will be have longetive.

In conclusion, heritage want to have longetive need to humans protect if they do not protect heritage, it will be longer historical.

There are two phenomenons coule be atributted to the tourism and the climate change. And I believe that they are the common problems could affect badly to the cultural heritage sites. To begin with, the amount of visitors are increased every years. Thats mean their behaviour could harm to our country cultural heritage. They could litering, touch the statues and the old buildings. An example that in The Temple of Literature, some people touch turtle statues head and made them atrophy through the timeline.

On another hand, these place could be demolished gradually by climate change. Bad weather like axit rain is taking a part in destroying not only the environment but also the cultural heritage sites.

To deal with these problems, i suggested some potential solutions. First, the authority should banned the act like touch in the old buildings and only allow people to take pictures with it. This could reduce part of the impoverishment. Second, i think the government must encourage the citizen to deal with the climate change.

To conculde, i think that the cultural heritage sites could be protected if each person have their own conscious of the important of these place.

In particular, Trang An is a heritage recognized by UNESCO. Trang An is a mysterious natural area that is not subject to much human impact, so it is still pristine with jungle, clear blue streams and fresh air. But now this heritage is facing many different problems such as due to the individual consciousness of each person or due to sunshine, rain, weather; Heritage sites are constantly deteriorating, budgets are limited, and management is poor. So there needs to be solutions to solve the above problems. People need to improve their sense of self-awareness when visiting monuments and heritage sites, constantly renovating monuments and increasing funds for renovations.

Accordingly, Ninh Binh has developed and organized the good implementation of the heritage management plan with the goal of ensuring harmony between conservation and tourism development, so that heritage is truly the property of the community, protected by the community and for sustainable development, inclusiveness of the community. Every year, specialized local management agencies regularly organize training and fostering programs to improve the understanding and responsibility of the community for world heritage sites. This is the core for people to voluntarily and voluntarily participate in protecting Trang An heritage.

Trang An Relic Area is part of Trang An Scenic Complex, located in Ninh Binh province. Covering an area of more than 2,000 hectares, the area includes a network of waterways, limestone mountains and caves. Trang An has a 250 million-year-old limestone geological system with a diverse ecosystem. Emperor Dinh Tien Hoang chose Trang An as the southern protective barrier for the capital Hoa Lu in the 10th century.

However, at the present time, Trang An ruins are facing many problems in the preservation of the relics. A large part of tourists, both domestic and foreign, are not conscious of preserving cultural heritage. That increasingly makes the monument unaesthetic and does not show the meaning it brings. Besides, under the influence of nature, the year-round climate makes the architecture degraded.

So I think we need some solutions to fix the above problems. People need to raise awareness of the importance of preserving cultural heritage. Local government agencies need to regularly repair and upgrade structures that are degraded due to nature, climate and people.

In conclusion, I think we need to have a sense of preserving cultural heritages not only Trang An heritage area but also many other architectural works in the world. When we explore a new ruin, we also add to ourselves more knowledge about history.

The art of creating patterns with beeswax on the costumes of the Mong people in Muong Cha district was recognized as a national intangible cultural heritage in 2018, but up to now the locality has not Is there any activity to restore or pass on to the next generation? The commune does not have funds to organize this activity. Currently, only a few old people know how to draw this pattern, beeswax and other materials are no longer used, so it is very difficult to promote this heritage. Every day this cultural heritage becomes less and less known.

This is a unique cultural feature of the ethnic people. First the government and each individual should propagate and promote more so that this cultural heritage will be more interested and known to everyone. Second the government should invest in facilities to make it easier for people to paint and preserve beeswax. Third organize museums or events to introduce and promote them to local people and foreigners.

In conclusion, i believe that these measures could help a part of preserving the cultural heritage sites.

The first problem that the river encounters is water pollution. This is one of those problems that is all too common but no one can stop it absolutely, even worse than when discovered. So what's the reason? The first is due to human consciousness, there are people who dump waste into the river or even throw garbage and defecation, making the river become polluted. Sometimes factories dump waste that makes the river worse. The 2nd problem is climate change, one of the problems affecting our lives, but even the river, without timely measures, the river will definitely not be as intact as it is now

To overcome the above problems, what should we do? First we should be more conscious, do not litter indiscriminately, go to the right place, limit the discharge of waste into the river that causes the river to become polluted and factories should find ways to treat the waste discharged from factories. As for climate change, we should plant more trees to create shade for the river so that the river does not dry up and keep itself.

Im tried so hard and got so far. But in the end, it doesn't even matter.

To prevent the destruction of Halong Bay, it is necessary to have short solutions to stop or reduce the problems it is facing today. Water pollution originates from the plastic waste of other tourists as well as the waste of factories. For each tourist, it is necessary to strictly follow the regulations on garbage disposal in the right place. Coastal water stalls restrict takeout mussels and only use disposable cups at the bar. In addition, groups can be organized on weekends to pick up trash along the bay .Next, on the issue of illegal fishing in protected areas on the bay. Erect fortified barricades and prohibitions and increase security around the area. Finally, the problem of buffer zones being leveled and during construction causes air pollution and affects people's lives. It is necessary to have a team to supervise the construction and transportation process to ensure minimal smog and dust released into the air. The regional management ministry should consider carefully before signing the approval for the construction of the project.

To sum up, there are some solutions to tackle these problems such as: Stricten regulations on disposing of trash in the right places, fence off conservation areas and finally closely monitor areas being leveled to build urban areas

There are two main problems that Mekong Delta River facing. First, environmental pollution here is showing signs of increasing sharply, floating landfills on the river surface dumped by surrounding people are polluting the water. Waste pipes directly discharged into rivers, polluting water sources. Second, aquatic resources are gradually depleted because people exploit them non-stop, by improper exploitation such as placing mines in the river bed, seafood species cannot grow

To fix above problem, destroy waste sources that pollute water sources, morover, catch seafood properly and breed more seafood

In conclusion, Mekong river delta is an important river for Vietnam and we need to protect and preserve it

The Mekong River is facing a number of negative problems that seriously affect its ecosystem and water quality. In the coming years, any changes related to water flow, flow, and temperature in the Mekong River that threaten the ecosystem in this region will lead to the risk of water insecurity. In particular, one of the events affecting that is the historic drought from 2019, lasting into 2020, is getting worse when the water level continuously reaches record declines. It is also worrying that countries along the. Mekong region are implementing policies to increase the construction of hydropower dams on the mainstream to meet the region's growing energy needs. The reason is that population growth will increase the demand for water and energy. Environmental experts say current dams threaten to reduce fish stocks, alter water flows, reduce silt used for crop fertilization and rice production. In addition, the change in water flow by hydropower dams will cause a negative impact on rice cultivation productivity, affecting food security in the region.

To find reasonable solutions for the management, sharing and use of Mekong water resources, serving the increasing demand from human daily life and production and maintaining the sustainable development of the environment, people need to innovate the way water resources are managed and used. All socio-economic development activities must be based on the actual capacity of water sources and water balance, in accordance with future water resource development trends. Strengthen monitoring and monitoring of water use throughout the basin. Monitoring data should be shared with countries in the basin.

After all, we need to take steps to help prevent and improve the river's ecosystem from climate change, man-made causes to make the river better and above all, to protect and improve it for future uses

The authorities also have many solutions to overcome this problem. For the old town: Maintain the architectural form and structure of the old town and relics; Conservation promotes heritage value on the basis of ensuring the preservation of the originality of the monument; Find ancient documents about trading, trading, and commercial activities to rebuild the image of the old town, thereby bringing back the true emotions and images of the old Cang Thi city; Limit the commercialization of the old town.. Citywide space: Develop a plan to orient the development of city space to become a green urban area - ecological urban area
