Human impact on biodiversity
Human activity is a major threat to the planet's biodiversity. This is because human population growth thus far has been exponential, meaning that its growth rate stays the same regardless of population size. This makes the population grow faster and faster as it gets larger.
Populations may grow exponentially for some period, but they ultimately reach a carrying capacity when they become limited by resource availability. Humans, however, have continued to work around carrying capacity as they develop new technologies to help support the ever-growing population.
This threatens biodiversity because the more humans there are, the more this displaces other species and reduces species richness.
Human-mediated causes of biodiversity loss
Deforestation for resource mining or urbanization can displace native organisms.
Destruction of forest in Madagascar.
Land-use change: Humans may destroy natural landscapes as they mine resources and urbanize areas. This is detrimental, as it displaces residing species, reducing available habitats and food sources.
Pollution: Pollution can occur from the runoff or disposal of chemical substances, or from energy sources (noise and light pollution).
Introduced species: Humans may intentionally, or unintentionally introduce a non-native species into an ecosystem. This can negatively effect an ecosystem because the introduced species may outcompete native organisms and displace them.
Resource exploitation: Humans constantly consume resources for their own needs. Some examples include the mining of natural resources like coal, the hunting and fishing of animals for food, and the clearing of forests for urbanization and wood use.
Extensive overuse of nonrenewable resources, like fossil fuels, can cause great harm to the environment. Recycling products made from nonrenewable resources (such as plastic, which is made from oil) is one way to reduce the negative impacts of this resource exploitation. In addition, the development and use of renewable resources, like solar or wind energy, can help decrease the harmful effects of resource exploitation.
Climate change and biodiversity
The current climate change Earth is facing is caused by the increase in global temperatures.
Human activity is changing Earth's atmosphere faster than it has ever changed during its history.
