Biodiversity has always been in a flux with species adapting to new surroundings or extinction but these situations are all through natural occurrences and through a period of a large number of years and so allowing the dependant consumers and trophic levels to adapt. However, because the Human population commenced to expand hugely since the industrial revolution we have been directly in charge of the extinction of a large number of species including the Traveler pigeon (Ectopistes migratorius) and indirectly responsible for many others. As the population continues to grow we will require more resources and to broaden our living area, in this case we have exploited the natural resources to breaking point and have expanded into man-made products that harm the ecosystem even more. The idea that people should be working to repair the damage that has been caused by our rapid growth is a relatively new strategy and has still not been accepted by many countries but attempts are being designed to protect the remaining areas and ecosystems.
Humans have modified ecosystems for our gain such as agriculture which targets the mass creation of a selected few products for our ingestion; this is incredibly effective in nourishing a large society while making use of only 3 trophic levels, the company (plants), the principal and supplementary consumers (humans, livestock). This method also benefits energy, keeping any damage at the very least especially when combined with artificial fertilizers and pesticides. However when taking a look at the damage this technique causes to other populations there may be huge fallout, we use pesticides which kill any local insect populations, and fertilizers run off the domains and contaminate the neighborhood areas, freshwater and coastal ecosystems both biotic and abiotic. we effectively damage large areas to support these fields which remove natural habitats for many types which places an enormous strain on the ecosystem (McShaffrey: http://www. marietta. edu/~mcshaffd/)
Using biotechnology researchers have modified blue green algae to do something as a cost-effective bio fertilizer, utilising its natural nitrogen fixation to add nutrients to plants instead of counting on the more harmful, synthetic fertilizer, minimizing harmful ramifications of the man-made chemicals, using natural bio waste materials and recycling energy flows far more successfully. http://agritech. tnau. ac. in/org_farm/orgfarm_biofertilizertechnology. html) Team of Agricultural Microbiology
The human influence on the ecosystem has damaged many areas both immediately and indirectly such as air pollution, local climate change and benefits of foreign species. Within the last 50 years the global monetary activity has increased 7 collapse in the last 50 years and tendencies suggest that as our people continues to rise the ecosystem are affected more http://www. greenfacts. org. Land and forests are in better demand for agricultural, industrial and cover which kill natural habitats of indigenous species and drive them out. Forest fragmentation escalates the threat of extinction as small a space small the populace it can support. Merging this with the introduction of alien kinds, i. e. imported from other countries and then escape into a fresh ecosystem, this is a major reason behind the extinction to local species like the North american mink escaping into the British isles countryside, this non-native carnivore has posed a substantial threat to fish, poultry and game birds, The introduction of new diseases that can prove disastrous, Dutch elm disease has destroyed the English elm tree which then saw a huge decline in the companies for air and allowed more non-native trees to increase in their place.

"Ecosystems already are showing negative influences under current degrees of weather change which is humble in comparison to future projected changes. In addition to warming temps, more recurrent extreme weather situations and changing habits of rainfall and drought can be expected to possess significant impacts on biodiversity". (Secretariat of the Convention on Biological Variety (2010)
Pollutants such as olive oil, gas fumes, and man-made chemicals have created the most popular impact to the ecosystem with temperatures in flux, the polar icecaps melting, acid rainfall and the harm to the Ozone part. Native plants are unable to flourish in the acid wealthy soils making for fewer producers and less for the primary consumers to soak up this holds throughout the chain (Ann N Y Acad Sci. 2009)
In bottom line, While biodiversity is still present it holds true that the increased pressure has from contaminants and destruction of natural environments has greatly influenced the improvement, wiping out many kinds and allowing other to thrive in their stead have modified the ecosystem totally. However because the intro of conservation plans there are indicators that harm is slowing, however, not significantly, ultimately for the biodiversity to recover to a sustainable amount we need to employ a rigorous long term intend to reduce any more growth and concentrate on technology or all natural remedies to repair any recoverable damage from the environments
