Undoubtedly, natural disasters have a negative impact on the economy. Governments should provide some assistance to disaster victims in the aftermath of such events. However, they must fundamentally mandate development in disaster-affected areas that is appropriate for the type of disaster. As long as we live in harmony with nature rather than in opposition to it, we are a species capable of ensuring our survival. Species that refuse to live in harmony with nature, or that are unable to do so, have always failed and will continue to fail...
Another problem comes out when there's the disaster even in the sending of help to the victims. If there's a river flowing so much water and mud, then that kinda delays the aide that they need to have. It slows down economy and as well as the help that the victims need. And I do believe about what you've said that if we take care of nature, then it will also take care of us. This is the truth about life and as we grow older, we also have to accept the fact that even with so much care, a natural disaster is uncontrollable and it can't be dictated.
However, some disasters remain unpredicted and uncontrollable. This is why a government should have an advance plans and actions regarding climate disasters because once there is preparation, worst outcomes will also be prevented, if not totally avoided.
I agree, disaster preparedness should be on the shoulders of the government and not only when it comes, that's the time they'll plan.
