Deforestation and Habitat Loss

This category deals with the causes and effects of changes in natural habitat. Examples would include questions about cutting down forests, plowing grasslands for agriculture, coral reef die-offs, and the natural process of succession.

What does 'Earth's carrying capacity' mean?

To understand the global magnitude of the loss and degradation of earths life support systems affect all that inhabit the earth. From photosynthetic limits to food, wood and freshwater in order to satisfy increasing demands.

Where does most of the carbon dioxide released by human activities come from?

Most of the carbon dioxide in our atmosphere comes from nature. Specifically, it comes from rotting material. A tree that is rotting in the forest produces the same amount of CO2 as a tree being burnt.

How many countries are there in your world?

No country has ruled the entire world. However, there have been empires that have ruled the 'known' world from their perspective.

Perhaps the first great global ruler was Alexander of Macedonia (Alexander the Great)

Then there was the Roman Empire

The Holey Roman Empire

and perhaps the largest of all, The British Empire.

In modern times counties/empires seem to be fragmenting rather than growing.

Does redwood rot?

Redwood has a natural resistance to decay due to its high levels of tannins and oils. This makes it highly resistant to rot and decay, which is why redwood is a popular choice for outdoor furniture and decking. However, like all wood, redwood can still decay over time if not properly maintained and protected from prolonged exposure to moisture.

What is the biggest forest in WA?

The biggest forest in Washington State is the Olympic National Forest. It covers nearly one million acres and is known for its diverse ecosystems, including temperate rainforests, old-growth forests, and alpine peaks.

What is a Spiderwasps Habitat?


a Spiders natural habitat is any where that has 2 or more surfaces that they feel is comfortable to catch food and or lay eggs

Does Douglas-fir grow in Georgia?

No, Georgia doesn't have the right climate! There is only one Douglas fir that I know of in the state and it is planted at the University of Georgia. However, you can look at it and tell that its not happy to be there.

What is the solution to deforestation according to experts?

Experts recommend a combination of sustainable logging practices, reforestation efforts, protection of existing forests through conservation and restoration, and reducing demand for products that drive deforestation, such as palm oil and beef. Additionally, enforcing strict regulations and monitoring illegal logging activities can help address deforestation.

What is the difference in adaptations between plants and animals of a polar region?

Plants and animals of the polar region require the conservation of heat and to some extent water. Most animals that have adapted to the cold environments, are shorter in stance, longer coats, shorter ears, all in an effort to conserve heat and energy. In contrast, a desert environment would exhibit animals with longer legs, long ears, shorter less thicker coats, in an effort to dissipate heat, rather than conserve it.

Importance of biogeochemical cycle?

Without the biogeochemical cycle there would be no potential for life, as life as we know it is dependent upon such elements as carbon, oxygen, nitrogen, and hydrogen, and such things could not be circulated without the biogeochemical cycle, and without life as we know it as a result of element circulation as a result of the biogeochemical cycle, there would be no potential for high school biology students to ask questions that they'd know the answers to if they had payed attention in class.

Explain the conflicts over water and dams in India?

Conflicts over water and dams in India arise due to competition for water resources among various stakeholders, including farmers, industries, and local communities. Dams are often constructed to address water management issues, but they can lead to displacement of communities, environmental degradation, and disruption of natural flow patterns, sparking protests and conflicts. Moreover, water sharing among different states can be a source of inter-state disputes, complicating the issue further.

What is shallow water zone?

The shallow water zone refers to areas of water that are relatively shallow in depth, typically between the shoreline and deeper offshore waters. These zones are important habitats for various aquatic plants and animals, as well as for young fish and other marine life. Shallow water zones can also play a role in processes like water filtration, nutrient cycling, and wave attenuation.

Does cutting down trees effect the ozone layer?

It reduces the future amount of oxygen available. Less oxygen means less ozone.

It increases the temperature below the thermocline, so it allows more water vapor across to reduce ozone levels.

If the forest is burned, it releases chlorine-containing molecules into the air, some of which will make it to the ozone layer to reduce ozone levels.

Looks like deforestation means less ozone into the future.

What is the definition of Chemical Pollution?

Chemical pollution is the introduction of harmful chemicals into the environment, such as water, air, or soil, which poses risks to human health, ecosystems, and wildlife. These chemicals can come from various sources, including industrial activities, agriculture, and improper disposal of household products.

Changing area under forests and its impact on environment?

Clearing forests for agriculture, urban development, or logging decreases the area under forests, leading to loss of biodiversity, disruption of ecosystems, and increased greenhouse gas emissions. This can result in soil erosion, water pollution, and habitat loss for many species, ultimately impacting the stability of the environment and contributing to climate change. Efforts to protect and restore forests are crucial to mitigate these negative impacts and promote environmental sustainability.

Why does deforestation happen?

Deforestation happens primarily due to agricultural expansion, logging, urbanization, and infrastructure development. These activities lead to the clearing of forests for human use, resulting in loss of biodiversity, disruption of ecosystems, and climate change. Economic incentives and weak enforcement of conservation laws also contribute to deforestation.

What is the cicdas habitat?

The habitat for the cicadas includes large woody bushes and trees with soil that is well drained. They live in climates that are temperate to tropical with warm summers and are found all over the world.

What advantage to the flower are colored petals?

Colored petals attract pollinators like bees and butterflies, aiding in the process of pollination. This increases the chances of successful reproduction for the plant, as pollinators are attracted to bright colors.

How does deforestation affect humans?

Deforestation can have negative impacts on humans by leading to loss of habitats for indigenous communities, disrupting ecosystems, contributing to climate change, and increasing the risk of natural disasters like floods and landslides. Additionally, deforestation can reduce the availability of resources like clean water and medicinal plants, impacting human health and well-being.

Where can you find a rain forest in the US?

America's rain forests are located in Alaska between the Arctic Circle and the Tropic of Cancer, and are therefore called temperate rain forests. The only tropical rain forests in the United States and its territories are in Puerto Rico.

Where can you find a rainforest in the US?

The largest rainforest in the US is the Hoh Rainforest in Olympic National Park, located in the state of Washington. It receives high levels of precipitation and supports a diverse range of plant and animal species typical of a temperate rainforest ecosystem.

What are some nonliving things in Antarctica?

Snow, ice, wind, Southern Lights, water, sunshine, rocks.--southern lights, sunshine, and wind are NOT objects. You cant touch them

How does deforestation affect the water cycle?

Trees store and transpire great quantities of water; it's one of the reasons rainforests remain humid and wet. Take away the trees and that store of water is lost. Moisture cannot be returned to the atmosphere without the plants. Because neither water or nutrients can cycle in a forest ecosystem after the trees are cut down, extensive cutting can convert lush forests into deserts.

Another problem is that erosion occurs due to increased runoff (unabsorbed rainfall). Soil and plant material loosens and falls into the water. This can also contribute to flooding. If there's too much deforestation near the water, the soil will subside, because trees are what hold it in place.

It increases the amount of runoff.
