what gases? I'll guess that you mean oxygen. Natural source - the air, man-made - none.
There is real ivory- a natural animal product, such as elephant ivory, walrus ivory, etc, and there is artificial manmade ivory.
Shelter is not considered a natural resource for animals, as it is typically provided through their own efforts or by utilizing natural materials in their environment. Natural resources for animals would include things like water, food sources, and habitats.
Natural habitation refers to the environment or location where a particular species naturally lives, grows, and thrives without human intervention. It includes factors such as climate, vegetation, food sources, and other elements that are essential for the species to survive. Protecting natural habitats is crucial for the conservation of biodiversity and the well-being of ecosystems.
It is best to not feed wild moose as they have specific dietary needs and natural food sources. Feeding them human food can be harmful to their health and may disrupt their natural foraging habits. It is important to respect wildlife by letting them find their own food in their natural habitat.
Airborne particles and gases that occur in concentrations large enough to endanger the health of organisms are known as air pollutants. These pollutants can come from various sources such as vehicle emissions, industrial processes, and natural events like volcanic eruptions. Prolonged exposure to high levels of air pollutants can lead to serious health issues, including respiratory problems, heart disease, and cancer.
Greenhouse gasses or GHGs (carbon dioxide, methane and a few others) are emitted from natural and manmade sources. The Earth is set to handle the amount from natural sources, but the extra from manmade sources tips the balance to cause a slow increase in the GHGs. Mankind can restore the balance by * reducing the emissions from fuel burning (the primary cause) or * by increasing the amount taken from the air by increasing forest cover or the creation of other carbon absorbing systems.
