e soil is a living organism of fabulous complexity. Soil systems
contain some of the most species-rich communities in nature. Most
authors describe soil communities as being amongst the most species-
rich components of terrestrial ecosystems [1,2]. Well-developed
temperate woodland soils may contain up to a thousand species of soil
fauna [1]. Soil communities are described as “the poor man’s tropical
rainforest” [3]. It is noteworthy that only a proportion of all the soil
animal species has been described and very little is known about their
role, community structure and dynamics. Research concerning soil
is not purely an academic subject. e soil is the very basis of earth’s
productivity. It is fundamental to agriculture and forestry, water
purification and biogeochemical cycling, and is the grounding for
civilization [4]. is is particularly true where human activity tends to
induce irreversible disturbances. At a time when demographic pressure
is too high, and when the needs of human population are intense and
immense, it is wise to realize that the soil is central to human survival.
Meanwhile, soil biology has fallen somewhat behind advances in the
understanding of other types of communities [3]. Soils are still the
least understood habitats on Earth, while also being among the most
biologically diverse [4].
Scientific analyses indicate that no area is unaffected by human
influence. Significant changes in physical and biological systems are
occurring on all continents and in most oceans. Over 80% of land area
is under the direct influence of humans [5], a large fraction of marine
ecosystems (41%) is strongly affected by multiple drivers [6]. e impact
of human activities on the planet has accelerated the loss of species and
ecosystems to a level comparable to a sixth mass extinction, the first
driven by a living species. e current rate of species extinction is now
approximately from 1000 to 10,000 times higher than natural rates [7].
Approximately 60% (15 out of 24) of the ecosystem services evaluated
are being degraded or used unsustainably [8]. Despite the fact that life
in soils is still an enigma, there is no logical reason why soil organisms
would be excluded from these processes. It seems of great importance
for science and society to know how many species of bacteria, fungi
and invertebrates live in soil system and what are critically important
ecosystem services provided by them? What kind of further scientific
investigations are needed to achieve an accurate quantification of
threat to soil biodiversity and essential ecosystem services?
ere is lack of information on the current levels of below ground
biodiversity and it difficult, therefore, to quantify the effect that human
activities are having influence on the soil biota. However, there is
evidence that soil biodiversity and ecosystem services provided by the
biota in many areas are already in decline [9,10]. If these services are
diminished (through the loss of biodiversity), then this could prove
expensive for humankind. Ecosystems provide at least US$33 trillion
dollars worth of services annually. About 38% of this estimated value
comes from terrestrial system. e important part of it comes from
soil biota [7,11]. e list of threats to soil biodiversity is long. e risk
of soil degradation (loss of biodiversity and diminishing of ecosystem
services) is mainly caused by human activities through different forms
of soil and land use. But we are added new threats to this list, e.g.
invasive species or genetically modified plants. Some invasive species
appeared to reduce the diversity and abundance of soil organisms, as
well as the nutrient fluxes processed by the soil community [12,13].
ere is evidence for disruption of the food chain of soil organisms,
which leads to a reduction in biological diversity, and evidence of
extinction in cereal crops GM beneficial fauna [14,15].
Some authors underlined that to avoid the mistakes of past societies,
the world must address global soil degradation, one of this century’s
most insidious and under-acknowledged challenges [16]. A key task
for soil science is to estimate and mitigate the loss of soil biodiversity
and the degradation of ecosystem function, gauge the capacity of soil
system to withstand disturbance and species loss. Further investigation
into some of the following research questions is needed:
• Why soil system is so diverse and how many microorganisms,
fungi and invertebrates do live there?
• What is the relative impact of various human activities upon soil
biodiversity and the supply of ecosystem services?
• What is the effect of the estimated loss of species on the
functioning of soil system?
• To what extent, and over what time scale, are ecosystem services
in soil amenable to repair or restoration?
• Which loss of species the soil system can handle and, therefore,
continue to function and provide essential ecosystem services?
Our society should support research devoted life in soil and
promote practices and technologies that cultivate beneficial soil life and
sustain soil ecosystems. It’s time to take seriously the life under the feet.
