The effects that climate change has on both plant and animal species within certain ecosystems has the ability to directly affect the human inhabitants who rely on natural resources. Frequently, the extinction of plant and animal species create a cyclic relationship of species endangerment in ecosystems which are directly affected by climate ...
Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment.This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources.
A follow-up scientists’ warning on climate change in 2021 reiterated the need to plan and limit human numbers to achieve sustainability, proposing as a goal "stabilizing and gradually reducing the [global] population by providing voluntary family planning and supporting education and rights for all girls and young women, which has been proven ...
Both agricultural plants and animals depend on pollination for reproduction. Vegetables and fruits are an important diet for human beings and depend on pollination. Whenever there is habitat destruction, pollination is reduced and crop yield as well. Many plants also rely on animals and most especially those that eat fruit for seed dispersal.
In biology, overabundant species refers to an excessive number of individuals [1] and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7]
It depicts the continuing sixth mass extinction, caused by humans, and the consequences of biodiversity loss and climate change. It also suggests positive action which can be taken to halt or reverse these effects. With a peak viewership of roughly 4.5 million on its premiere, the programme received positive critical reception.
Furthermore, climate change may cause ecological disruption among interacting species, via changes in behaviour and phenology, or via climate niche mismatch. [9] For example, climate change can cause species to move in different directions, potentially disrupting their interactions with each other. [10] [11]
