【22】Green Transportation Infrastructure




When it comes to the idea of a green transportation infrastructure, that’s pretty easy. All one has to do to get across the idea is to highlight the experience virtually all of us have shared at some point in our life.

Bus lanes
A lot of city dwellers profess an interest in taking the bus to work, but when pressed about why they don’t, there are plenty of reasons keeping them in the cars. Convenience is obviously one, but having to wait at a bus stop and then sit or stand on a crowded bus while cars go by is definitely another big impediment. But cities around the world are doing their best to harness the environmental benefits of bus ridership by making them more attractive to ride. How? One major way is by creating lanes dedicated to buses so that they can zoom past cars and trucks on roadways. Part of a concept called bus rapid transit, dedicated bus lanes have been around for decades and are used in South America, Europe and increasingly in North America and Asia.

Subways
Sure, anyone who rides the New York City subway -- or those in a lot of other cities, for that matter -- everyday will probably snicker (or worse) at the categorical statement that subways are clean. But while some individual subway cars and buses could use a good cleaning, the reality is that these modes of public transport take a heck of a lot of cars off the road and contribute mightily towards a greener planet.

【21】World Environment Day 2015



Every year, the United Nations Environment Program honors World Environment Day on June 5 to raise awareness about environmental issues and call for action.
This year’s theme for WED – Seven Billion Dreams. One Planet. Consume with Care – therefore expresses the challenge of creating opportunities for inclusive and sustainable economic development, while attempting to stabilize the rate of resource use and reduce environmental impacts. China announced the theme of this year’s event: Live in a green lifestyle.

The topic is a particularly powerful one, because there’s room for everyone to take a moment to question how we live and how it impacts the planet. The theme asks everyone to evaluate our consumer habits: how we shop, eat and travel.

China is facing with the resources and environment pressure, the main pollutant emissions close to or more than the status of the environmental capacity. The environment quality is poor, hazard, high risk, while the social public demand and expectation gap is larger. Therefore, with improving the environment quality, intensifying pollution control at the same time, the whole society should advocate thrift and civilized healthy rational consumption, promote public green consumption concept and behavior.

【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.
