2015世界环境日/ World Environment Days 2015

今年世界环境日的主题是"70亿人的梦想：一个星球，关爱型消费"。人类社会、环境和经济的福祉最终取决于对自然资源的负责任管理。但是，相关证据表明人类消耗了远远超过地球可持续提供的自然资源。

随着世界人口数量的不断增长，以及经济的快速发展，地球生态系统已经逼近"临界点"，一旦极限被突破,人类生存环境将面临"不可逆转的变化"。预计到2050年，全球人口数量将增长至96亿，如果不改变目前的消费和生产模式，届时人类将需要3个地球的资源才得以满足生活和消费的需求。

关爱型消费是指生活在地球的"界限"以内，确保人类可以在一个健康的未来实现梦想，人类社会的繁荣不再以消耗地球资源为代价。可持续生活就是利用更少的资源去做更多更好的事情，让人们意识到消耗自然资源以及造成的环境影响不是经济发展的必然副产品。

The well-being of humanity, the environment, and the functioning of the economy, ultimately depend upon the responsible management of the planet’s natural resources. Evidence is building that people are consuming far more natural resources than what the planet can sustainable provide.

Many of the Earth’s ecosystems are nearing critical tipping points of depletion or irreversible change, pushed by high population growth and economic development. By 2050, if current consumption and production patterns remain the same and with a rising population expected to reach 9.6 billion, we will need three planets to sustain our ways of living and consumption.

The WED theme this year is therefore "Seven Billion Dreams. One Planet. Consume with Care." Living within planetary boundaries is the most promising strategy for ensuring a healthy future. Human prosperity need not cost the earth. Living sustainably is about doing more and better with less. It is about knowing that rising rates of natural resource use and the environmental impacts that occur are not a necessary by-product of economic growth.
