The picture tells us that a disease has broken out and is probably spreading.

shipwreck
space
water shortage
It shows us a dense jungle.
People would find it difficult to travel and to navigate (导航).
It would also be difficult to find food and water. Wild animals and venomous(有毒的) insects are also potential problems.
Difficulties
In the picture, we can see an astronaut in space.
Space is the most extreme environment for human beings. They face danger from extreme temperatures, low pressures and radiation(放射). They must carry everything they need with them, even air. The lack of gravity(重力) makes simple actions such as eating, drinking, moving and even sleeping difficult. Anyone who spends too long in a zero-gravity environment risks losing bone and muscle mass.
Difficulties
This picture shows us a severe drought or water shortage.
Without water, people and livestock face death within a short period of time. In addition to water shortages, drought causes crop failure, so people would face food shortages as well. This could affect people who do not live in the drought-affected area. Severe food shortages can cause famine(饥荒), migration, collapse of social order and war.
