What makes an ecosystem healthy and maintain and can healthy ecosystems better withstand and recover from a variety of disasters?
A healthy ecosystem is made up of native plant and animal populations that interact in harmony with one another and with nonliving things. A healthy ecosystem has an energy source, which is usually the sun. The sun provides radiant energy for the growth of producers. A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. Healthy ecosystems can better withstand and recover from a variety of disasters. Thresholds can be managed by supporting stable ecosystems, which are less prone to collapse. The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem's ability to remain stable when confronted with a disturbance.

High-speed landslides can generate air waves, which are also known as air blasts, due to the rapid movement of the landslide mass. The mechanical mechanism behind the generation of air waves by high-speed landslides is complex and involves several factors.
One of the primary factors is the sudden release of energy that occurs during the landslide. As the landslide mass moves downhill, it displaces a large volume of air in front of it. This displaced air creates a high-pressure zone, which propagates outward from the landslide as a shock wave or air blast.
Another factor that contributes to the generation of air waves by high-speed landslides is the fragmentation of the landslide mass. As the mass moves downslope, it can break apart into smaller pieces due to the forces acting on it. This fragmentation creates additional air pockets that are rapidly compressed and decompressed as the landslide moves, generating additional air waves.
The speed and size of the landslide also play a role in the generation of air waves. Larger and faster-moving landslides can generate more powerful air waves than smaller or slower-moving landslides.
Overall, the mechanical mechanism of air wave generation by high-speed landslides is complex and depends on several factors. However, the primary mechanism involves the rapid displacement of air by the landslide mass, which creates high-pressure zones that propagate outward as shock waves or air blasts.
Healthy terrestrial ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits. Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water, and clean air. These are things like air, water, rocks, soil, metals and nutrients. Inorganic matter is important in an ecosystem because it is what producers use, and it is the physical and chemical, non-living environment that we live in.A healthy community is dependent on a well-functioning ecosystem that contains fresh water, unpolluted air, and food security. A healthy ecosystem is one that is intact in its physical, chemical, and biological components and their interrelationships, such that it is resilient to withstand change and stressors.Condition indicators tell us whether an ecosystem is in a good state. They include indicators of habitat, species and resources, such as water and carbon. Function indicators tell us the extent to which ecosystems retain their natural function and so have the capacity to deliver a range of benefits.
