Sometimes animals ingest pollutants that can become stored in their fat and tissues. Human-caused pollution has added heavy metals, oil, and industrial and pharmaceutical chemicals to the environment. As the chain of predator and prey continues up the food web, the toxins become more concentrated and move higher and higher up the food web. The process that causes the concentration of a substance to increase as it moves up the food web is called bioaccumulation.
The pollutants can have a disastrous effect on the food web and potentially kill species. A natural disturbance is any event that causes a disruption to the current state of an ecosystem. Natural disturbances are caused by forces of nature, including weather, geology, and biological fluctuations. This may include fires, floods, earthquakes, diseases, and droughts.
After a disturbance impacts an ecosystem, there can be devastation, but healthy ecosystems have an amazing ability to bounce back. Some ecosystems even depend on disturbances, such as the threatened longleaf pine ecosystem. Sometimes the ecosystem will go back to its former structure, with the same plant and animal species. Other times, the disturbance will create something new by allowing new species to populate the area.
Not all disturbances are natural. Human actions have contributed to many disturbances seen in ecosystems today. While natural disturbances happen on occasion, human disturbances are putting constant pressure on ecosystems and dramatically impacting species. Human disturbances, including clear-cutting, habitat fragmentation, and pollution, are continuously affecting ecosystems. The moment the ecosystem begins adjusting to one stress, another appears.
Many ecosystems that we depend on are not given enough time to adapt to the new conditions. The natural cycle of disturbances—growth, dieback, and growth—cannot properly function because too many disturbances are putting pressure on the ecosystem at once. Wild animals are always on the move. They move from place to place in search of food, mates, shelter, and water. Many animals do not have to move far in order to have all their needs met, but other animals—for example migratory birds, wolves , mountain lions , or butterflies —require much more space.
Currently many species with large territories, including gray wolves, are threatened because habitat loss and fragmentation have limited their available space. Roads, fences, and buildings cut off habitat and force wildlife into smaller areas. Conservationists have to take into account the different spatial needs of wildlife when designing plans to protect them.
They have to think about the territory size, different habitat types, and migration routes that wildlife need. A wildlife corridor is a tract of land that connects different wildlife habitats such as refuges, parks, or rivers that might otherwise be separated by human development.
Wildlife corridors provide many benefits to wildlife. With corridors, animals have a better opportunity of finding the basic necessities they need—food, water, shelter, and places to raise their young. Animals that require larger territories can access new habitats and maintain a healthy territory size.
Wildlife corridors also promote genetic biodiversity. When more individuals of a species are interconnected, the gene pool becomes larger and more viable. Migratory wildlife benefit from corridors because they can move safely over long distances without having to come into contact with human developments or cars. Nature-based solutions are central to the UN Environment Program.
We are facing a planetary emergency for climate, nature and humanity. Unsustainable human activities, from farming and mining to industry and infrastructure, are undermining the productivity of vast areas of farmland, forests and other ecosystems. This degradation threatens food security, water supplies and the biodiversity upon which human development depends.
It drives and is exacerbated by the climate crisis. Without animals though, nature is non-existent because ecosystems cannot be sustained; and without ecosystems, there is none of the life support that our species and civilisation depends on. Our biggest challenge and opportunity is to rebuild wildlife populations because that stability adds up to a fairer climate with less extreme weather events, deeper soils, cleaner water and a richer ocean.
Knowing where and when to find food and water is critical for our entire lives and economies. Rebuilding a world rich with diverse and abundant wildlife is the only solution for a habitable planet.

Everything is connected. World Bank-supported reforestation in the hills of Rio, Brazil has been good for wildlife and people. Healthy wildlife populations signal that the water table, which provides reliable water for the city, is working.
Reforestation has also made communities safer from landslides, restored trees that absorb carbon dioxide and earned revenue-generating carbon credits for the city. When we protect animals and plants, we also protect the ecosystems that underlie our economies and well-being.
