2 . Landscaping (人造景观) refers to man-made features of a landscape such as driveways, walls, steps, and other human-made structures. It has many sustainability benefits.

Replace Lawns (草坪)

Fertilizers and pesticides (化肥和杀虫剂) help establish a beautiful lawn.     1     If you replace lawns with landscape, you’ll use fewer chemicals and do less harm to the environment.

Use Less Water

    2     So it can save hundreds of gallons of water and reduce the carbon emissions (排放) used to provide that water cleanly.

Use Locally-Produced Materials

Materials for landscaping are almost all produced locally, due to the high shipping cost.     3    

Lower Garden Maintenance (维护)

Usually, Americans spend two hours per day on lawn and garden care.     4     That often means less energy used to run some garden equipment.

Reduce Ice Build-up

Sustainable landscape allows stormwater to drain (流) into the soil.     5     This means safer walkways or driveways, and a reduced need for salt for de-icing (除去……上的冰).

6 . Climate Acts Must Focus on Youth

Children and young people are bearing the burden of climate change. However, they are consistently overlooked in the design and content of climate policies and related measures. The rights of the youth need to be put in a central place in a country’s climate change plan as extreme weather events are threatening their lives and destroying the infrastructure critical to their well-being.

The scientific community has sounded the alarm that climate change is a global emergency, and the risks of deadly drought, frequent floods, heat waves, extreme weather, and poverty will significantly worsen.

Over half a billion children live in high flood zones and nearly 160 million live in areas of extremely high drought, said a report released in 2015 by the United Nations Children’s Fund, or UNICEF. Polluted air has a huge impact on children’s brain development. It is estimated about 2 billion children live in areas with air quality that is well above international pollution standards. Air pollution, lack of safe water, undernutrition is strongly linked to pneumonia, a leading cause of death among children, killing nearly 2, 400 children a day. The increase of diseases such as malaria and dengue fever has the greatest impacts on children, for example, 90 percent of the disease burden that is attributable to climate change is born by children under the age of five. The UNICEF report said all these challenges are exacerbated by climate change.

Through the intergovernmental cooperation on climate change, the UN has made it clear the impacts of climate change are global in scope and unprecedented in raising. Actively responding to climate change is not only imperative, but also key to sustainable development for generations to come as children and young people are the future of mankind.

We are all glad to see children and young people are encouraged to play a key role in addressing climate-related risks by promoting environmentally sustainable lifestyles and setting an example for their communities.

10 . There exist a great variety of national parks that are representative of the different regions of the world. To reveal and maintain the great diversity of the interactions between humans and their environment, and to protect living cultures and preserve the traces (痕迹) of those which have disappeared, these sites have been included in the World Heritage List.

Lushan National Park, China

Mount Lushan, in Jiangxi, is one of the spiritual centres of Chinese civilization. Buddhist and Taoist temples, along with landmarks of Confucianism blend (融合) effortlessly into a strikingly beautiful landscape which has inspired countless artists who developed the aesthetic (美的) approach to nature found in Chinese culture. Special attention has been placed on protecting the cultural heritages and their settings as a whole.

Dinosaur Provincial Park, Canada

In addition to its particularly beautiful scenery, Dinosaur Provincial Park — located at the heart of the province of Alberta’s badlands — contains some of the most important fossil discoveries ever made from the “Age of Reptiles”, in particular about 35 species of dinosaur, dating back some 75 million years. These fossils are valuable materials for scientists to study the history of the earth.

Kaziranga National Park, India

In the heart of Assam, this park is one of the last areas in eastern India undisturbed by a human presence. It is inhabited by the world’s largest population of one-horned rhinoceroses, as well as many mammals, including tigers, elephants, panthers and bears, and thousands of birds.

Komodo National Park, Indonesia

These volcanic islands are inhabited by a population of around 5,700 giant lizards, whose appearance and attacking behaviour have led to them being called “Komodo dragons”. They exist nowhere else in the world and are of great interest to scientists studying the theory of evolution.
