Bet365 app download According to the official website of the University of Wyoming University in the United States, recently reported，Todd L. Cherry, a professor of economics at the school's business school, said，Environmental supervision agencies need to conduct more scientific experiments，Only to provide more effective reference information for policy formulation，to improve policy effectiveness。

Formal Experimentation is the cornerstone of science。Correct grasping causal relationship is the core of formulating effective environmental policies and bet365 best casino games environmental protection projects。But，Chery and others discovered，Formally experiments have almost no existence in environmental protection projects。Environmental scientists and environmental protection practitioners generally tend to pass through field experience、Case research and the retrospective assessment of the project to collect useful information for the policy。But the original intention of these research activities is not a causal relationship that enables the policy to act on real environmental protection objects。Blindly relied on the above method when designing environmental protection projects or policies，It will even play the opposite role。

Chery and others recommend that more formal experiments will be carried out in bet365 best casino games environmental protection projects，To enhance causal reasoning。The so -called "formal experiment"，It is to make space or time adjustment during the implementation of the plan，Quantitative analysis of its effect and clarify the mechanism。For example，Many environmental protection agencies want to make relevant industries more comprehensively abide Bet365 lotto review by environmental protection regulations，Including the "one -size -fits -all" audit plan，It is better to adopt different audit plans in various industries，Compared with the feedback of different industries。Chery and others believe，Methods to intend to change environmental policies，It helps project managers to identify more effective features。

It is true，Environmental scientists participate in thousands of non -formal experiments every year，For example, pilot project。but，They can neither detect the hidden assumptions of the current bet365 best casino games environmental protection projects，It is not specifically designed to improve the performance of the project。Some reasons for the lack of Bet365 app download formal experiments in environmental protection projects originated from the history of environmental policies。relative to health、Social policies in the fields of poverty alleviation and education，The development of environmental policy Bet365 app download is shorter，It is also late to collect scientific evidence with innovative methods。In addition，Effective environmental protection projects added to society are not as obvious as other social policies，Various losses caused by the invalidation of the project are not significant。This makes environmental scientists not bear any pressure in confirming the effectiveness of environmental protection solutions。other，People who play the leading role in environmental protection projects are usually lawyers、Engineer、Natural scientists。and health scientists、Different behavioral scientists and social scientists，They are not deepened by their grasp of experimental design principles based on real operating situations，Therefore, the complicated human response to policies and projects lacks predictability。

In the past 30 years，The National bet365 best casino games environmental protection Administration and the US Department of Agriculture have added Bet365 app download formal experiments in environmental protection projects less than six times。All environmental protection plans implemented by governments in European countries only include an example of a formal experiment。In non -governmental organizations and multilateral environmental agencies，Formally experiments have almost no existence。Although environmental scientists and environmental protection practitioners hold different opinions for the time and energy needed for formal experiments，But both parties acknowledge，The number of formal experiments is zero is not the best choice for improving the effectiveness of environmental policies。In Chery and others, it seems，Make a large -scale environmental policy change，Then evaluate its results，It is not as required to require institutions and organizations to take out scientific evidence before making decisions。The government should launch an incentive measure of formal experiments or adjust the specification Bet365 app download system，to strengthen the experimental culture in the field of environmental protection。
