Worst Environmental Problem? Overpopulation, Experts Say
ScienceDaily (Apr. 20, 2009) — Overpopulation is the world’s top environmental issue, followed closely by climate change and the need to develop renewable energy resources to replace fossil fuels, according to a survey of the faculty at the SUNY College of Environmental Science and Forestry (ESF).

Just in time for Earth Day (April 22) the faculty at the college, at which environmental issues are the sole focus, was asked to help prioritize the planet’s most pressing environmental problems.

Overpopulation came out on top, with several professors pointing out its ties to other problems that rank high on the list.

“Overpopulation is the only problem,” said Dr. Charles A. Hall, a systems ecologist. “If we had 100 million people on Earth — or better, 10 million — no others would be a problem.” (Current estimates put the planet’s population at more than six billion.)

Dr. Allan P. Drew, a forest ecologist, put it this way: “Overpopulation means that we are putting more carbon dioxide into the atmosphere than we should, just because more people are doing it and this is related to overconsumption by people in general, especially in the ‘developed’ world.”

“But, whether developed or developing,” said Dr. Susan Senecah, who teaches the history of the American environmental movement, “everyone is encouraged to ‘want’ and perceive that they ‘need’ to consume beyond the planet’s ability to provide.”

The ESF faculty pointed to climate change as the second most-pressing issue, with the need to develop renewable energy resources to replace fossil fuels coming in third.

“Experimenting with the earth’s climate and chemistry has great risks,” said Dr. Thomas E. Amidon, who invented a process for removing energy-rich sugars from wood and fermenting those sugars into ethanol. “This is a driver in climate change and loss of biodiversity and is a fundamental problem underlying our need to strive for sustainability.”

Rounding out the top 10 issues on the ESF list are overconsumption, the need for more sustainable practices worldwide, the growing need for energy conservation, the need for humans to see themselves as part of the global ecosystem, overall carbon dioxide emissions, the need to develop ways to produce consumer products from renewable resources, and dwindling fresh water resources

Worst Environmental Problem? Overpopulation, Experts Say
专家说最严重的环境问题是人口过多
ScienceDaily (Apr. 20, 2009) — Overpopulation is the world’s top environmental issue, followed closely by climate change and the need to develop renewable energy resources to replace fossil fuels, according to a survey of the faculty at the SUNY College of Environmental Science and Forestry (ESF).
ScienceDaily（2009年4月20日报道）—据针对纽约州立大学环境与林业学院的教职员的一项调查表明，人口过多是世界上首要的环境问题，紧随其后的是气候变化和发展可再生能源来替代矿石能源。

Just in time for Earth Day (April 22) the faculty at the college, at which environmental issues are the sole focus, was asked to help prioritize the planet’s most pressing environmental problems.
值地球日（4月22日）即将到来之际，这个以环境问题为主要关注焦点学院的教职员们被要求排列出我们的行星主要面临的环境问题。

Overpopulation came out on top, with several professors pointing out its ties to other problems that rank high on the list.
人口过多最终列于首位，而且有几位教授指出它和其他位于前列的环境问题相关。

“Overpopulation is the only problem,” said Dr. Charles A. Hall, a systems ecologist. “If we had 100 million people on Earth — or better, 10 million — no others would be a problem.” (Current estimates put the planet’s population at more than six billion.)
“人口过多是唯一的问题，”系统生态学家Charles A. Hall博士说，“如果地球上只有1亿人—或者更理想些，只有1000万—其他的就都不是问题了。”（目前估计地球人口在60亿以上。）

Dr. Allan P. Drew, a forest ecologist, put it this way: “Overpopulation means that we are putting more carbon dioxide into the atmosphere than we should, just because more people are doing it and this is related to overconsumption by people in general, especially in the ‘developed’ world.”
一位森林生态学家Allan P. Drew博士这样说道：“人口过多意味着我们排出了过多的二氧化碳进入大气，仅仅是因为更多的人在排出二氧化碳，而且这也和人们的过度消费相关，特别是发达国家。

“But, whether developed or developing,” said Dr. Susan Senecah, who teaches the history of the American environmental movement, “everyone is encouraged to ‘want’ and perceive that they ‘need’ to consume beyond the planet’s ability to provide.”
“但是，不管是发达或发展中国家，”教授美国环境运动史的Susan Senecah博士说，“每个人都被鼓励去‘索取’并且发现他们‘需要’消耗的已经超出了这个行星所能提供的。”

The ESF faculty pointed to climate change as the second most-pressing issue, with the need to develop renewable energy resources to replace fossil fuels coming in third.
环境和林业学院的教职员指出气候变化是第二大的问题，发展可再生能源来替代矿石能源排在第三位。

“Experimenting with the earth’s climate and chemistry has great risks,” said Dr. Thomas E. Amidon, who invented a process for removing energy-rich sugars from wood and fermenting those sugars into ethanol. “This is a driver in climate change and loss of biodiversity and is a fundamental problem underlying our need to strive for sustainability.”
“拿地球的气候和化学来做试验是有很大风险的，”发明了从木材中提取高热量的糖并将其发酵成乙醇的方法的Thomas E. Amidon 博士说，“这是气候变化和生物多样性丧失的驱动，也是要追求可持续发展面临的基本问题。”

Rounding out the top 10 issues on the ESF list are overconsumption, the need for more sustainable practices worldwide, the growing need for energy conservation, the need for humans to see themselves as part of the global ecosystem, overall carbon dioxide emissions, the need to develop ways to produce consumer products from renewable resources, and dwindling fresh water resources
环境与林业学院列出的前10位的问题还有：过度消费、世界范围内的可持续发展、节约能源、认清自己是地球生态系统的一部分、二氧化碳的过度排放、发展从可再生资源生产消费品的方法、淡水资源的减少。
