The potential harm to the ecosystem.

Migrating birds affect ecosystems both at home and at their winter destinations, and disrupting the traditional routes could have unexpected side effects.

The Millennium Ecosystem Assessment, a vast four-year global study which reported its initial conclusions earlier this year, found reasons to believe that managing ecosystems sustainably—working with nature rather than against it—might be less profitable in the short term, but certainly brings long-term rewards.

Sustainable management of ecosystems will prove rewarding in the long run.

More than a decade later, there was no sign of the ecosystem re-building itself.

Managing ecosystems sustainably is more profitable than exploiting them, according to the Millennium Ecosystem Assessment.

Companies that have long focused on hardware now have to think of ecosystems instead to give consumers practical solutions to their everyday problems.

From the standpoint of a traditional educator, this outcome indicated that schooling had failed to help students think about ecosystems and extinction, major scientific ideas.

However, a further increase in farming area without impacting unfavourably on what remains of the world's natural ecosystems appears unlikely.

A further expansion of farming area will adversely impact on the world's natural ecosystems

A decade ago, this island's ecosystem was in chaos.

As trees outgrow their ideal habitats in the face of climate change, these flying ecosystem engineers could be a big help in replanting trees.

It also highlights incidents of fishing boats being involved in groundings, oil spills and accidents, which posed a serious threat to the Antarctic ecosystem.

Managing ecosystems sustainably is more profitable than exploiting them, according to the millennium Ecosystem Assessment.

Our long-term operation in the region depends on a healthy and thriving Antarctic marine ecosystem, which is why we have always had an open dialogue with the environmental non-governmental organisations.

The study by Greenpeace analysed the movements of krill fishing vessels in the region and found they were increasingly operating "in the immediate vicinity of penguin colonies and whale feeding grounds" It also highlights incidents of fishing boats being

This unique ecosystem may soon be under pressure.

"We're bringing new blood into the old, conventional farming ecosystem, which is really cool to see," Collins explains.

By connecting directly with customers, and by responding quickly to changes in the markets as well as in the ecosystems (生态系统), small farmers can keep one step ahead of the big guys.

Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown.

It is the rules governing food webs of the ecosystems.

Mathematical models have also revealed that food webs may be unstable, where small changes of top predators can lead to big effects throughout entire ecosystems.

Phytoplankton play a declining role in the marine ecosystem.

Prevention is key, scientists says because once ecosystems pass their tipping point, it is remarkably difficult for them to return.

This view is especially evident on kilimanjaro as climbers go through five ecosystems in the space of a few kilometers.

Uncontrolled human activities greatly upset ecosystems.

They did not always prioritize the protection of Mauna Kea’s fragile ecosystems or its holiness to the island’s inhabitants.

The success of Sci-Hub, which relies on researchers passing on copies they have themselves legally accessed, shows the legal ecosystem has lost legitimacy among its users and must be transformed so that it works for all participants.
