加拿大阻止森林大火成本?

如果我们的目标是减少空气中烟雾的总量一半,每年有多少数以百万计的美元,我们谈论吗?我设想雇佣数百人找到火灾蔓延之前,也许有一些高科技的方法从卫星遥感热……请选择最符合成本效益的解决方案。

什么使你的钱能解决这样的问题?加拿大,像大多数其他国家倾向于大火没有足够的消防人员参加所有这类火灾。目前,加拿大[签署协议][1]接受消防队员从美国、墨西哥、哥斯达黎加、澳大利亚、新西兰和南非。加拿大有566的消防人员到目前为止443年带来了来自美国、澳大利亚和新西兰。目前共有1009人。期间(2019/20灾难性的火灾)[2],澳大利亚收到援助:加拿大、斐济、法国、印尼、日本、马来西亚、新西兰、巴布亚新几内亚。菲律宾、新加坡、阿拉伯联合酋长国、美国。它还利用[6500自己的国防军事人员][3]。还有消防设备的问题和获得所需要的:卡车;水* * * *; back burning equipment; water bombers; equipment for cutting line breaks: graders, bulldozers. Getting enough water to a fire could problematic. Access to remote areas, particularly in mountainous or heavy undulating terrain will also be difficult. Are there roads to such areas and are they in good condition. The rotation and rest of fire fighters is critically important. Weather conditions are critical: air temperature (particularly wet bulb temperature), wind speeds and directions, moisture content or dryness of the air, the possibility of the formation of [fire tornadoes][4] or [pyrocumulus cloud][5]. Weather conditions during the preceding years also important, particularly if it encourages the growth of new forest vegetation, particularly undergrowth. If conditions are too favorable too much dry undergrowth can develop. The only way to remove it is by controlled burning during wetter, cooler periods. Knowing if such conditions exist requires monitoring. One of the unpleasant realities of fires on such a scale as they currently are in Canada is humans cannot extinguish the conflagration. Humans can attempt to prevent fires from escalating. Fires on such a scale are extinguished by either wet weather or they just burn out by running out of fuel.

\ begingroup美元你指出的挑战,但我从来没有说过或认为这是容易森林大火作斗争。我仍然认为一些钱可以减少一半的烟,例如每年十亿美元可以雇佣另一个10000名消防员。或者,这些钱可能最好花在一些无人机技术。江南登录网址app下载只是希望听到最便宜的可用选项,因为在附近很多人愿意贡献更好的空气质量。 \ endgroup美元
