Advantages Of Biodiversity
Biodiversity is the biological variety and variability of life on Earth and a measure of variation at the genetic, species, and ecosystem level. It provides physical, consumable goods and services that we could not live without such as - air, water and food. Beyond physical goods, our natural environments, and the biodiversity within them, can provide intangible benefits to society such has helping tackle some of our key health issues. Like tourism, biodiversity’s role in agriculture and food production is also vital to our economy. Growing crops and rearing animals, would not be possible without the numerous and complex interactions that happen below and above ground between different species. All the great benefits from biodiversity depend on our nature being just that, diverse. For any ecosystem to function it needs a lot of components, and removing any of these will make this complex system weaker, or even make it collapse.

Forest are the most diverse ecosystems on land, because they hold the vast majority of the world's terrestrial species. Some rain forests are among the oldest ecosystems on Earth. Timber, pulpwood, firewood, fodder, meat, cash crops, fish and medicinal plants from the forest provide livelihoods for hundreds of millions of people worldwide. But only a fraction of known species has been examined for potential medicinal, agricultural or industrial value. More than 10 million different species of animals, plants, fungi and micro-organisms inhabit the Earth. They and the habitats in which they live represent the world's biological diversity, or biodiversity as it is often called. Humans use at least 40,000 species of plants and animals on a daily basis for food, shelter, clothing and medicinal needs.

Forest fulfil numerous important fucntions and do so particularly well if they have diversity of tress . Forest are great Importance to humans . the wood grown in forests is used in our houses for furniture , roof timbers and flooring root timbers and flooring : forest store carbon from air and thus counteract climate change and they help prevent soil erosion and regulate the water cycle .

Foxes are carnivores with a keen sense of hearing and smell. Due to the lack of natural enemies and sufficient food, it can be said that Australia is a paradise for them. However, due to their large numbers, they have threatened the survival of some small herbivores. It will carry a lot of germs, so the government encourages people to shoot them, but the effect is not obvious.
