What will happen to biodiversity in the future?

1 Biodiversity loss will lead to a deterioration of the benefits that humans obtain from ecosystems. It will increase the likelihood of ecological surprises, such as rapid climate change, desertification, fisheries collapse, floods, landslides, wildfires, eutrophication, and disease.

Why is biodiversity important for the future?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

What is happening to biodiversity?

Plant and animal species are disappearing at an ever faster rate due to human activity. … Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.

What happens to the biodiversity on the planet over time?

The number of species on the planet, or in any geographical area, is the result of an equilibrium of two evolutionary processes that are ongoing: speciation and extinction. Sudden and dramatic losses of biodiversity, called mass extinctions, have occurred five times. …

What will happen if we continue losing biodiversity?

Biodiversity loss affects economic systems and human society. … This lack of biodiversity among crops threatens food security, because varieties may be vulnerable to disease and pests, invasive species, and climate change.

How does biodiversity affect human life?

Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.

What is biodiversity Why is biodiversity important for human life?

Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services.

How are we losing biodiversity?

The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world’s ecosystem, In fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly, for example by fishing and hunting, changing the biogeochemical cycles and …

Where is biodiversity loss happening?

Micronesia and Polynesia. Called the “epicenter of the current global extinction,” by Conservation International, this smattering of more than 4,000 South Pacific islands is at risk from both local human activity and global climate change. Humans settled on these islands between 2,000 and 3,000 years ago.

How has biodiversity increased over time?

Biodiversity Change through Geological Time

Both are natural “birth” and “death” processes of macroevolution. When speciation rates begin to outstrip extinction rates, the number of species will increase; likewise, the number of species will decrease when extinction rates begin to overtake speciation rates.
