What are the biggest threats for individual groups of animals?
The biggest threats are:
the depletion and pollution of the natural habitat of animals due to human activities, such as agriculture (growing of mono-cultural crops), raw material extraction, building of new settlements and roads, etc.
illegal hunting and capturing (hunting for trophies, illegal wildlife trade, animal use in folk medicine)
Everyone can help wildlife animals very simply:
by preservation of green vegetation and inanimate nature, natural biotopes and food sources
by preventing people from leaving waste in nature and from creating of illegal waste dumps
by separation of waste
by decreasing the use of water and electricity
by using environment friendly products (recycled paper)
