Provide Two Examples Of Human Activities That Alter Biodiversity

One example humans have impacted aquatic ecosystems has been through the introduction of invasive species. Invasive species are a

In contrast to the upheaval of animals in a development area, humans also make efforts to preserve biodiversity and forests by creating wild life

A species that is introduced to an ecosystem by humans can harm ecosystems in many ways. Animals that are introduced into a new area, could hunt a main food source for some animals, causing that population to decrease. Plants could be poisonous, or need to feed off of other plants. Species introduced into an ecosystem by humans through off the natural balance of the wildlife.

The article discussed the changes in many habitats due to anthropogenic activity. Anthropogenic is an adjective that describes changes in nature due to the people. Next, this article discussed climate change and the impact that it is having on species like clams, and fish due to ocean temperatures rising. The article also addressed carbon dating of fossils to look for cause of extinctions. Human development and agriculture have had a tremendous impact on the population of many species that are terrestrial. Deforestation is a big problem that has caused a decline in the bird species. Commercial fishing in many areas has led to a decline in fish populations. Furthermore this article

Forests have been cut, crops planted, pastures seeded, and urban areas paved. One of the most troubling consequences of human modification of ecosystems is an ongoing loss of species and therefore a loss of biodiversity around the world. The current extinctions have a human cause: habitat loss (such as clearing of tropical rainforests); the introduction of invasive species; unregulated hunting and fishing; and pollution of water, air, and

In contrast, the natural environment and wild animals were negatively impacted by human activities. Burning forests in untouched land made low nutritional soil. As a result of this, erosion took many areas and made empty fields. Also, wild animals lost their habitat because forests were disappearing and people changed landscapes. People were looking only at benefits to improve their lives, and therefore wild animals would not be considered.

People can especially influence biodiversity in the IRL in a negative way. There can be a major loss of habitat from development on the shoreline, like resorts and hotels (“The Indian River Lagoon,” n.d.). Due to the lagoon’s shallowness, it can become overcrowded very quickly. It it’s too overcrowded, the nutrients in the water will suffer and there will be too many particles. Humans are disrupting the growth of the many species in the IRL, and they are preventing them from reaching their full potential. There must be a variety of animals and plants for there to be biodiversity, and people are seizing both land and water that should be used as habitats for the animals in the

1. Briefly describe how our species started to appreciate the biodiversity of the planet (in a geographical and historical context)?

Humans do things like: Overhunting, deforestation, pollution and land conservation, destroying the environment for food, materials and research etc. This destroys habitats for certain creatures affecting the whole ecosystem, possibly killing the organisms in the ecosystem.

Now the animals have to compete with the humans for food and space but as time passes by the humans begin to dominate food and space for example they pollute the fish’s river ad began using the bear cubs as footballs. This eventually caused the animals to move out of the area. This was analogous to Hardin key assumption that if there are more people in the finite world then each person will get less since we cannot maximize the carry capacity of an ecosystem and satisfy every person’s

Two local examples of our impact would be habitat destruction and over-hunting. As the human population grows, so does the amount of land it requires for food and shelter. As a result of this, people cut down and destroy the places where animals live in to make way for farmland and other types of agriculture. This forces animals to move to a different area. However, some animals are overspecialized and can only survive in a specific environment. Therefore, when forced to leave, they will not be able to survive. This can lead to extinction in that area, otherwise known as extirpation. Over-hunting can also lead to extirpation. In today's society, we are more prone to hunting animals, whether it be for economic or personal gains or for food. This can reduce the the amount of animals in that area. Both of these examples affect biological diversity because when animals go extinct, specific traits can be lost. Then, when the rest of the species goes to breed, they won’t have the trait that may have helped them survive in their

How has biodiversity on earth changed over time?Many scientists may ask themselves this question, but they all have different responses.In the lab we did in class I got to decide my answer for this question and I believe that biodiversity has increased over time.To get my evidence I looked at a data table with all of the biological classification schemes.This is my argument because after I looked at the data table I came up with the conclusion that biodiversity has increased.

Humans have existed since 200,000 years but the Earth has existed around 4.5 billion years. Nature has provided us with everything we have today - food, medicines, materials, chemicals, metals, minerals etc. It can only keep providing us when we maintain the right environment for it to exist. This environment depends on the biodiversity of Earth. The number of species of plants, animals and microorganisms and the various genes in these species, different ecosystems such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Hence Biodiversity impacts everything. We will discuss how Biodiversity plays a crucial role on social, environmental, and economic factors. We will also discuss what

The Human Impact on Rainforests Human Impact on Rainforest is it a necessity? Rainforest are the beautiful gift of Mother Nature. It consists of the most magnificent species and plants in the world. 4.2% of the world’s animals live in the rainforest. This statistic it self shows how bad it would be to destroy such essential part of the worlds biodiversity.

Deforestation for agricultural purposes and the expansion of human habitats is happening around the world. This
