Clean, Convenient, and Cheap

Big cities like New York and London have a lot of great things. They have museums, parks, shopping centres, and a huge variety of restaurants. However, there are a lot of annoying things in big cities. The most common problems are air pollution and noise.

Traffic is the main cause of air pollution and noise. For example, drivers in New York are famous for honking their horns and shouting. That noise drives many visitors crazy - it even drives a lot of the locals crazy, too. Other big cities have similar problems with their traffic.

City governments have a lot of pressure to solve these problems. The most common solution is public transportation. Public transportation is a form of travel provided by the government. For example, New York's biggest form of public transportation is the subway.

Public transportation helps reduce these problems, but it is not enough. Another solution is bicycle sharing. This is a system that provides cheap bicycles. In cities that have bicycle sharing programmes, there are spots that have parked public bikes. People borrow the bikes and use them. They can drop off the bike at the same spot where they borrowed it, or they can drop it off at another spot.

Bicycle sharing programmes are different in each city. In some cities, the bikes are completely free. They are not even locked. In other cities, you have to pay a small deposit. You get the deposit back when you return the bike. In still other cities, you need to have a membership with the bicycle sharing programme. Once you have a membership with the bicycle sharing programme, you can use a bike at any time you want.

Bicycle sharing is hugely popular all over the world. People love this system because it is cheap, clean, and easy to use. There are bicycle sharing systems in dozens of countries and hundreds of cities. In total, there are more than 530 bicycle sharing systems around the world. and that number is going up all the time.

Viet Nam Likely to Face Extreme Weather Conditions by 2050

Viet Nam is likely to continue facing extreme weather conditions such as higher temperatures, lower summer rainfalls, stronger storms, and rising sea levels from now to 2050. Temperatures in northern Viet Nam will rise by between 0.83 degrees Celsius by 2050 and continue its uptrend during the late 21st century. Summer rainfall will decline in most areas. Meanwhile, storms may become rarer but fiercer, causing possible flash floods and landslides in flood-prone areas of northern mountainous, central and central highland provinces. The forecasts suggest sea level rises of 100mm - 400mm along the entire Vietnamese coast by the end of the 21st century, affecting marine biodiversity and coastal communities. The experts emphasize the unpredictability of climate change and its potential impacts to create a variety of dangerous extreme weather events in the future.

To raise the public awareness of climate change impacts, the Vietnamese government urges concerned agencies to work together on devising worst-case scenario models and responses by 2020 and calls on international experts to further support Viet Nam in climate change adaptation. Climate change is a real threat to Viet Nam’s socio-economic development. If sea levels rose one meter, five percent of the country’s land, eleven percent of its population and seven percent of its farmland would be affected.

Global warming and cooling have occurred naturally throughout history. But in the last 200 years, humans’ uses of fossil fuels and clear cutting of forests have increased the amount of carbon dioxide and other gases in the atmosphere. These gases trap some of the radiation from the sun which then increases the Earth’s temperature. Given the current state of environmental pollution caused by human activities, scientists believe the average temperature of the earth may increase 1-2 degrees Celsius which put simply, means some places will get much hotter and some much colder. At the same time, this overall warming effect means more frequent and more intense weather systems, especially in terms of flooding and drought.    

Viet Nam is one of the most vulnerable environments due to its location on the planet. It is already subject to some of the earth’s most powerful weather systems and the increased frequency and intensity of storms will affect it often and directly, especially in coastal areas where most people live. Various estimates have been made as to the possible impacts. The most directly affected sector will be agriculture, which is very sensitive to flooding and the effects of extreme weather.

Viet Nam has the advantage of coming relatively late into the industrialization, urbanization, and modernization process. This means it can avoid many of the mistakes made by wealthier industrial countries. For example, wireless communication networks can be built from the start rather than installing lines that can easily be destroyed in extreme weather. Cities can be designed and located in less vulnerable locations. Climate-friendly building codes and standards can be created that are both more efficient and less prone to heat stress, wind damage, and flooding. Climate friendly transport systems, especially public transport, can be adopted.
