Loss of Biodiversity and Extinctions

Biodiversity boosts ecosystem productivity where each species, no matter how small, have an important role to play ecosystems can better can withstand and recover from a variety of disasters. And so y. for example, a larger number of plant species means a greater variety crops; greater species diversity ensures natural sustainability for all life forms; and healthy ecosystems can better withstand and recover from a variety of disasters. And so while we dominate this planet, we still need to preserve the diversity in wildlife. The variety of life on earth, its biological diversity is often referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests, and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach to preserving biodiversity. Almost all cultures have their roots in our biological diversity in some way or form. Declining biodiversity is therefore a concern for many reasons.
Extinction has always occurred natural. Almost all species that have lived on Earth have become extinct. Perhaps they could not cope with changes occurring in the environment, such as climate changes, the intensity of predation or disease. The extinction of any species is an irrevocable loss of part of the part of the biological richness of Earth, the only place in the universe known to support living creatures. Humans have been responsible for almost all of Earth’s recent extinctions. These extinctions are occurring so quickly that they represent a modern mass extinction of similar intensity to those documented in the geological record. Examples of recent extinctions caused by humans include such well-known cases as the dodo, passenger pigeon and great auk. Many other high-profile species have been taken to the brink of extinction, including the plains bison, whooping crane, ivory billed woodpecker, right whale and other marine animals. These losses have been caused by insatiable overhunting and intense disturbing or conversion of natural habitats.
Extinction and biodiversity can greatly impact the environment, specifically the ecosystems that are balanced by its species and animals, for example ecosystems are designed to sustain a certain type of animals/species, and they both have an essential role in the system such as the food web chain. They both keep the ecosystem and the environment in balance.

But how does Extinction affect the environment?
When an animal becomes extinct, their relationship with other organisms or animals might cause them to become extinct as well due to the relationship destruction. Foods or areas may also be exploited by other animals or organisms in the area.
Humans rely on a host of invisible services that ecosystems provide. For example, they provide foods, medicines, and energy. They also regulate nutrient and waste, lock up carbon, they maintain clean air and water, crop pollination, seed dispersal, pest and disease control, they preserve genetic diversity and provide recreation for us all. It is the biodiversity on Earth that allows (at the moment) for animals, plants, and humans to share the planet- if one species is destroyed, several, maybe hundreds more, may follow. Biodiversity is important because certain animals have economic and life values (such as rainforests’ plants being made for into medicine), they have value to the ecosystem (think of their spot on the food web), and they are a source of natural beauty and recreation.
Ecosystem Disruption caused by the loss of biodiversity in an ecosystem can also cause environmental changes. Loss of one species may cause a chain reaction, resulting in a change in the ecosystem itself. Once the organism is gone, their role cannot be taken by any other organism because that species had evolved to be in that specific role in the environment. As we do not always know what specific role specific organisms play to its environment, we cannot predict how the ecosystem will be affected if that species was to be extinct. The whole ecosystem may be weakened by the process of extinction. Overall, these two factors are very important to consider when it comes down to a sustainable environment. Though the loss of biodiversity and extinctions are similar, both can have a catastrophic impact on the ecosystems which can effect humans in the end.
