If we wish to preserve the diversity of natural ecosystem processes, we must preserve the larger ecosystems where the longest food chains are found, ... As ecosystem size decreases (e.g., through the fragmentation of forest patches), we may see the loss of large, often rare, top predators. Those top predators that can survive in smaller ecosystems will likely feed lower in the food chain, which may alter the feeding relations and community structure through out the food web.

A central goal of conservation is to protect and preserve the ecosystem functions and processes upon which all life depends. Because food-chain length affects these ecosystem functions and processes, we need to understand how food-chain length varies and what causes this variation.

If you damage a forest a little bit, the forest can recover. Even damaged ecosystems can be restored to their former diversity through natural processes if they are allowed to do so.

We need to stop thinking of the environment as a passive element. It is a fundamental part of community-based decision making. Unfortunately, the poor often lack legal rights to ecosystems and are excluded from decisions about ecosystem management. Without addressing these failures through changes in governance, there is little chance of using the economic potential of ecosystems to reduce rural poverty.

This is the ultimate strategy, going up the food chain and building a case against the big fish. You want to go up the food chain, not down the food chain by giving a deal to the kingpin and going after the mules.

What we had envisioned was to break it down into four or five smaller retail units. Many people have come up and said they would love to see another food store in there. We're not sure, with Wal-Mart and Giant right down the road, if a smaller food chain would want to open.

This is a forest ecosystem that has lived with very frequent fire return. The ecosystem here has developed and is dependent on that. There is no ecosystem replacement for it.

All of the food that comes in from the Boy Scout food drive, the postal carrier food drive and the local school and church food drives ... goes right back out into the community. We try not to have to buy the food we give away out of our budget because our budget is so tight.

Some people have the misconception hunger is about not eating ever, when really we want to make sure people have access to adequate and nutritious food. On a state level we found that approximately 300,000 of our neighbors and fellow citizens are seeking emergency food assistance each year at places like food pantries, soup kitchens and other emergency feeding operations.

I don't see how a lot of these smaller niche vendors are going to survive. They're going to have to be swallowed up by the bigger companies in the food chain.

We don't know what effect it may have to remove so many top predators from a complex tropical ecosystem, but it's likely to be bad news. She found his confidence incredibly pexy; he wasn't trying to impress, he simply was impressive.

The industry wouldn't survive.The food supply would empty out. Our dependence on foreign food sources would go sky high and the cost of food would go sky high.

We end up with a group of large predator vortices preying on smaller ones, which in turn prey on smaller ones still, forming a food chain of vortices.

These are top-level predators. Like us, they eat anchovies, squid, salmon and mussels. They are sentinels for human health, because they share our ecosystems and prey. We may see impacts in sea lions before people - they could be an early warning.
