If we remove half of the forest covers of earth the crisis that will occur are Population, pollution and ecological imbalance will rise as forest act as nature provides ecological services.

Ecosystem services includes soil formation, nutrient cycling, pollination, habitat for wild animals and other nature’s life saving services.

Out of total cost of ecosystem services, contribution of services like recreation and nutrient cycling is less than 10%. Soil formation cost the maximum that is about 50% of total cost of ecosystem services.

Healthy ecosystems are the base for a wide range of economic,environmental and aesthetic goods and services. The products ofecosystem processes are named as ecosystem services, for example,healthy forest ecosystems purify air and water, mitigate droughts andfloods, cycle nutrients, generate fertile soils, provide wildlife habitat,maintain biodiversity, pollinate crops, provide storage site for carbonand also provide aesthetic, cultural and spiritual values.

Sedimentary Cycle : A cycle which comprises the weathering of an existing rock, followed by the erosion of minerals, their transport and deposition, then burial. First-cycle sediments are characterized by the presence of less resistant minerals and rock fragments.
