Eco­friendly Vauban, lied in the southwest part of Germany, has everything—tree­lined streets, perfect houses—but it's missing one urban feature of the last 100 years or so: the car. And Vauban residents don't mind one bit. Vauban doesn't ban cars entirely. Rather, it just tries to reduce the use of cars by creating "parking­free" and "car­free" living. In Vauban, parking spots are a no­no private property. Cars can only be parked in public parking lots, so living without a car saves residents the cost of parking in the public lot. Cars also are prevented from using certain roads and must stick to strict speed limits. With these limitations, fewer than 20 percent of residents own cars. And now, with a population of 5,500, it's attracting attention from around the world. Can an eco­friendly city like Vauban be a model for Americans to stop their over­ reliance on the cars?

Sometimes when I watch a news report what's in the back of my mind is what isn't being reported or stressed. While this eco­friendly city is inspiring in that it shows residents getting exercise and fresh air through the majority use of bicycles, as well as good old­fashioned walking, common sense would tell you that even for a place like Vauban, Germany, it owes its existence to the cars.

Do you think that bicycles were able to transport all the construction materials that were needed to build and maintain the eco­friendly homes and businesses in Vauban? It took cars to help build this city. It's one of the paradoxes of life that sometimes in order to get away from relying on something like the car, you actually have to rely on that very thing at the beginning and into the foreseeable future to some degree.

I myself haven't owned a car for more than 14 years, and mostly get around town running, walking, or using public transportation. There are times I wish I had one, since it would make many things easier, but overall I'm glad not to have to deal with the headaches of owning a car, which caused me to get rid of it in the first place. And all the walking and running has helped to keep me fit and healthy. To get even close to being like eco­friendly Vauban, Americans will need to absolutely change the way they live. Commuting (乘车上下班) patterns will have to change, public transportation will have to be invested in, and so on. And though ending our love affair with the car will be impossible during my lifetime, we may at least start to see more Vauban­like areas in the USA.

We can hope that Americans will consider using their feet more to get around, cutting down on pollution, and giving themselves some more exercise.

E-bikes are becoming more and more popular. It opens cycling to older people, those with disabilities, people who live in hilly cities where regular cycling requires serious effort.

Three things are needed to make e-bikes popular—a safe place to ride, good affordable bikes and a secure place to park. Safety comes first. For bike lanes (车道) to work, the network has to be continuous, not just forcing cyclists into the middle of a busy street. It should be well protected so that the cyclists won't feel they'll be knocked down by cars. It's necessary to provide good affordable e-bikes to customers either in physical stores or in online stores. Only in this way can people consider buying one as their means of transportation. Parking remains an avoidable problem if we want to encourage more people to ride e-bikes. In Netherlands or Copenhagen, large bike parking lots at train and bus stations encourage varieties of transport. People can easily find bike parking everywhere. This is going to be needed in other cities too for e-bikes to really become a form of transportation.

As a matter of fact, people have found that e-bikes are effective transportation choices. A recent study shows that people who ride e-bikes increase their travel distance from 2. 1 to 9. 2 km per day on average. That is sure to do good to their health. It's also believed that if just 15% of a city’s population turn to e-bikes, it would reduce the carbon emissions (排放) from transportation by 12%.

All of these lead me to conclude that e-bikes are a far better way of dealing with transportation emissions than electric cars. They won't work for everyone, but they don't have to.

China published its official document on biodiversity conservation on Oct 8,2021. It said that China has achieved great results in biodiversity conservation.

In 2010, the China National Biodiversity Conservation Strategy and Action Plan (2011-2030) was published. Since then, China has been working for a better ecological environment through establishing and improving policies and laws, carrying out nationwide biodiversity surveys, and putting into place various programs and action plans for biodiversity conservation.

There are about 10,000 protected natural areas, covering 18 percent of total land area. The well-planned protected areas system has brought 90 percent of terrestrial (陆地的) ecosystem types and 71 percent of key state-protected wildlife species under effective protection.

China has contributed up to 10 percent of the new plant varieties identified worldwide in the past decade. In this period, the country identified about 200 new varieties of plants per year.

The habitats for wild animals in China have been expanding and their populations are growing. The population of giant pandas in the wild has grown from 1,114 to 1,864 over the past four decades. The crested ibis (朱鹮) population has increased from only seven to over 5,000.

China was the largest contributor to the world’s gain in greenness between 2000 and 2017. The country contributed about 25 percent of global vegetation growth in the period and China’s forest coverage and forest reserve areas have both continued to expand for the last 30 years. The country has realized the largest growth in forest resources among all countries in the world.
