More than 50 years of research, development, manufacture, and testing of nuclear weapons at Department of Energy (DOE) sites
has left a legacy of on-site contamination that often spreads to surrounding areas. Despite substantial cleanup budgets in
the last decade, the DOE's top-to-bottom review team concluded that relatively little actual cleanup has been accomplished,
although milestones have been met and work packages completed. Rather than solely use regulatory constraints to direct cleanup,
many people have suggested that human and ecological health should guide long-term stewardship goals of DOE-managed sites.
The main questions are how ecological and human health considerations should be applied in deciding the extent of cleanup
that contaminated sites should receive and how near-term and longer run considerations of costs and benefits should be balanced
as cleanup decisions are made. One effort to protect ecological integrity is the designation of the largest sites as National
Environmental Research Parks (NERPs). Recently, the Competitive Enterprise Institute (CEI) suggested isolating and conserving
DOE sites as a policy priority because of their rich ecological diversity. A more effective long-term stewardship approach
for former nuclear weapons complex sites may emerge if the guiding principles are to (1) reduce risks to human and ecological
health, (2) protect cultural traditions, and (3) lower short- and long-term cleanup and remediation costs. A “net benefits”
perspective that takes both near- and longer-term costs and consequences into account can help illuminate the trade-offs between
expensive cleanup in the near term and the need to assure long-term protection of human health, cultural values, and high
levels of biodiversity and ecological integrity that currently exist at many DOE sites. 相似文献

This paper explores the effects of industrialization policy on environmental regulation in Puerto Rico, focusing on implementation of the Environmental Impact Statement (EIS) review process. Adopted in 1970, the EIS process has been transformed to pave the way for extensive use of a concise, alternative mechanism for analysing project environmental impacts, one with less opportunity for public input. This policy shift, virtually replacing the full‐scale EIS, occurred as a way to mediate the conflict between environmental policy and industrialization policy. Formal public participation in environmental decision‐making became the target of reform by the Puerto Rican Government because it perceived that public review was interfering with the location of industry. 相似文献

The aim of this review is to assess the ethical implications of finfish aquaculture, regarding fish welfare and environmental aspects. The finfish aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists. However, most biologists are at present acknowledging the probability of fish being sentient creatures. Current aquaculture practices are affecting fish welfare during all four of the cited stages, both on physical and mental levels, as well as on the ability of fish to carry out natural behaviors. The effect fish farming has on the environment is here separated into five different categories: the decline of wild fish populations; waste and chemical discharge; loss of habitat; spreading of diseases; and invasion of exotic organisms. There is evidence of severe negative effects on the environment when looking at these five categories, even when considering the difficulty of studying environmental effects, due to the closely interacting variables. The ethical arguments and scientific evidences here reviewed have not all come to the same conclusions. Nevertheless, the general agreement is that current aquaculture practices are neither meeting the needs of fish nor environment. Thus, the obvious environmental and animal welfare aspects of finfish aquaculture make it hard to ethically defend a fish diet. 相似文献

Livestock production in both industrial systems, where livestock are packed tightly together, and in highly traditional systems,
where a shepherd follows her herd in dispersed rangelands, are cited as key contributors in some of the most acute environmental
problems around the globe. Israel is one of the few countries where both of these systems exist, with surprisingly little
contact between them. The environmental impact of the sectors were examined along with Israel’s public policies in the field.
While historically, much attention has been placed on the contribution of the Bedouin pastoralists to desertification and
erosion, this may be linked to historic misapprehension about actual impacts of goats on local rangelands as well as political
motivations and concerns about losing national sovereignty over large areas of rangelands. The true environmental effects
appear to be minor. A far more critical concern is water pollution caused by the industrial sector of livestock production—an
issue that recently has attracted considerable government attention and investment in a successful dairy infrastructure initiative.
The divisions between governmental supports for the Jewish and Arab sectors of livestock management are inconsistent with
efficient environmental management. Policies should be designed to encourage Bedouin to find ways to sustainably continue
their traditional livestock husbandry practises, which today are largely associated with ecological benefits and constitute
a unique cultural asset for Israel and the world. 相似文献

In urban ecosystems, the ecological system has become completely unbalanced; this, in turn, has led to an increase in well-known
problems such as air pollution, ground pollution, and water pollution. This imbalance has also led to the growth and spread
of pathogens harmful to man, animals, and plants. Urban sustainability indicators, both global and local, also “indicate”
the percentage of population, but these refer only to the human population, not the animal population. Cities need good waste,
water, and air management, effective traffic planning, and good zoning of businesses, crafts, and services; over and above
these activities, cities also need for planning to take into account the existence of pets (dogs, cats, and etc.) and nonpet
animals (insects, birds, mice, etc.). Cities tend to be designed around humans and “on a human scale,” without taking into
account the fact that a huge animal population is living side by side with people. That explains why overcrowding tends to
go hand in hand with urbanization; all these populations, including humans, need to adapt to new spaces and often need to
drastically change their behavior. This is a fact that must be included when drafting sustainable city plans. The supposed
strategy is that of “integrated-participatory” control of the interactions between the environment and animals in the cities.
Strategy will focus on the development of integrated approaches and tools for environment and animal management in the context
of urban settings. This will require such specific methods as ecological balance sheets and ecoplans for the planning, management,
and control of the interrelation among environment, animal, and public health. The objective is to develop a better understanding
of urban biodiversity and of urban ecosystem functioning, in order to understand and minimize the negative impacts of human
activities on them. The research will focus on assessing and forecasting changes in urban biodiversity, structure, function,
and dynamics of urban ecosystems, with relationships among society, economy, biodiversity, and habitats. 相似文献
