In the scientific study Restoration ecology is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human intervention and action. There is consensus in the scientific community that the current environmental degradation and destruction of many of the Earth's biota is considerable and is taking place on a "catastrophically short timescale". Estimates of the current extinction rate is 1,000 to 10,000 times more than the normal rate. For many people, biological diversity, (biodiversity) has an intrinsic value that humans have a responsibility towards other living things and an obligation to future generations. Current research includes : A synthesis of soil carbon and nitrogen recovery after wetland restoration and creation in the United States, Comparing the plant diversity between artificial forest and nature growth forest, Deep carbon storage potential of buried floodplain soils etc.
