The world has become vulnerable to internal and external threats. Internal as in War that is imposed and terrorism etc. while external threats would be climate change that enforces threats like earthquakes, heavy rains causing floods, unexpected and unusual rise in the snowfalls are all making life tough for those who are residing in such sensitive areas.
While these suffering people are away their key concerns are adequate shelter and other basic daily routine consumables and first aid kits. These all come under core relief items that are provided by the relief items suppliers. International organizations like UNHCR work closely with the refugee tent manufacturers, so as to ensure that shelter needs are not an issue at any point.
