We need to focus conservation efforts not just on species, but also on the spaces they inhabit, and devote time and energy to understanding how ecological systems operate. For example, Kevan disagrees with attempts to save honeybees by developing mite repellents because this approach focuses on one species, not spaces and systems. Kevan says that a variety of pollinators working one crop enhances the number and the quality of fruit produced. The Forgotten Pollinators Campaign of the Arizona-Sonora Desert Museum also recommends combating the effects of the European honeybee decline by investing in alternative pollinators, both wild and managed, including alfalfa leafcutter bees, alkali bees, bumblebees, mason bees, and blue orchid bees. Unfortunately, putting theory into practice is not simple.
Funding is also problematic in implementing conservation practices.
As Eric Lawton of the Bureau of Land Management pointed out, agencies make decisions that they can afford, whether or not those decisions are the best ones for wildlife. Farmers also make decisions that they think they can afford. Many farmers are reluctant to change over to organic farming because they believe it will increase expenses, decrease crop yields, and shrink their markets. Pesticides cost money and if they aren't needed, farmers won't pay for them, said Janet Anderson of the Environmental Protection Agency. Many non-chemical controls are available for farmers but they need sound advice on how to use these.
