【20】Rabbit is a "green" pet




A pet dog‘s "carbon footprint" may be even higher than a car.

New Zealand Victoria university architecture professor Brenda Watt and Robert Watt measured that carbon emission of a medium dog a year is twice than a displacement of 4.6 liters of car driving 10000 km.

Pet's carbon footprint, of course, not only from the consumption of food, including detergents, pharmaceuticals, pet toys, clothing, jewelry, and other derivatives of the production, processing, transportation, and so on. And in the process of purchase and use of these products, a large number of packaging waste generated, causing a further negative impact on the environment. In addition, the outdoor range of stray cats and cats often threaten the survival of small wild animals such as birds, it is also a environmentalists often mention one of the dangers of pet.

Pets will produce environmental impact, of course, does not mean that people should not raise pets. In addition to reduce unnecessary items to buy, is in order to recycle all kinds of waste, change the pet food sources (more with local seasonal food DIY, instead of buying processed foods). Choosing the more environmentally friendly pet right from the start is also a very good method. Such as the rabbit has been named the "green" pets.

【19】Ecological footprint


my ecological footprint



What is an Ecological Footprint?

All of the resources which people use for their daily needs and activities come from somewhere, even if not from their immediate surroundings. Food, electricity, and other basic amenities for survival must be produced within the confines of nature, using raw natural resources. Based on this relationship between humanity and the biosphere, an ecological footprint is a measurement of the land area required to sustain a population of any size. 

The Footprint of Different Activities

This measure can also be presented in terms of the types of products or services provided by the global hectares, for example, in terms of goods from crop lands, animal products, fish, forest products, built up areas, and energy and water use. Such analyses identify which areas are placing the greatest strains on ecosystems, and can help set policy priorities. Growth in animal products and energy use, especially of fossil fuels, are two areas that are rapidly increasing these strains.

【18】The sustainable development of China's oil resources




After research the world's major countries oil consumption growth, there are two kinds of oil consumption growth model. Chinese oil consumption growth  After the analysis of the influence factors of oil reserves growth, and the reserves growth pattern analogy, China might have been at the peak of reserves growth. The reserves growth and production growth and found that the relationship between output growth curve is mirror of reserves growth curve.

According to the analysis and comparison of foreign history, China established oil resources sustainable development ability and petroleum safety supply ability evaluation index system, which come up with a comprehensive evaluation that China is currently in the weak sustainable development stage and oil resources supply capacity of weak security status. By 2020 Chinese petroleum supply is expected in the unsafe state.

To guarantee the sustainable development of petroleum resources and oil security, it should take strategic moves:

The first thing is to establish suitable for China's resources situation of energy consumption structure, insist on clean coal utilization of energy consumption, and vigorously develop natural gas and renewable energy;

The second is to actively exploration, rational utilization of domestic petroleum resources and maintain the long-term stability of the domestic oil supply.

The third is actively sharing resources abroad, stick to the policy of overseas development and import and import source, more diversified.

The last is to accelerate industrial structure adjustment, suitable for the automobile industry and consumer policy, gradually formed fuel-efficient economic system.

【17】Water resource management in China




From the principles of economics, water belongs to public goods, which shall be incorporated in the construction and management of government resources. Water environment protection and construction directly reflect and consider the degree of the government's management ability and strength. 

The important feature of water pollution prevention and control work in China is responsibility system in a place, and which also may be worth pondering and changing. For the pursuit of GDP and worship has become China's local governments the inertia of thinking, and the choice in pragmatism and ecologism between two very different views of development, as "economist" the government will, of course, choose the former without hesitation. Reason is very simple, which not only need to pay the cost of pollution control, also pay for the transfer of pollution control and economic benefits. As a result, those small chemical industries which should be completely shut down, paper making, small leather companies back from the dead. Using industrial enterprises along the river as the tools to lift GDP has become the consistent thought and action of local government

【16】Solar floor heating system




Solar energy is the energy which many countries advocated, because solar energy is inexhaustible.  Using solar energy is very environmental protection and energy saving. Solar floor heating system is mainly suitable for cold areas. Installation solar floor heating system will help households not have to worry about the attack of the cold.

Solar floor heating system mainly transforms the warm by radiant, so that we can provide the sun's heat energy to the object and the human body surface. If the inside and outside temperature are same, to achieve the same comfort, the ambient air temperature need to be lower than convection heating requirements about 3 . Solar heating floor system is very practical which obtains the vast number of consumers’ favor.


Solar floor heating system is not only a system of energy consumption, but energy production system. It has many good features, such as energy saving, cleanness, environmental protection, comfort, convenient for heat metering etc., which is a green way of heating. With the improvement of people's life quality requirements, the government's strong support, solar floor heating system will be more and more widely used.
