Afforestation
Afforestation is the process of seeding trees in non-forest lands and to help protect biodiversity.
152 Questions
How do forests control siltation?
Forests help control siltation by stabilizing the soil with their root systems, reducing erosion caused by water runoff. The trees and plants act as a barrier, slowing down the flow of water and allowing sediment to settle before reaching water bodies. This process helps maintain the water's clarity and quality by reducing the amount of sediment that can enter streams and rivers.
What are 2 examples showing how fallow land can be converted into agricultural land?
- Land can be cleared of existing vegetation, plowed, and tilled to remove weeds and prepare the soil for planting crops. This process helps rejuvenate the soil and make it ready for agricultural production.
- Fallow land can also be reclaimed through irrigation systems, where water sources are developed or redirected to convert the land into arable fields, allowing for the cultivation of crops in areas previously unsuitable for agriculture.
What controls the amount of uv light that enters the atmosphere?
The ozone layer in the Earth's stratosphere controls the amount of UV light that enters the atmosphere. Ozone absorbs and scatters UV radiation, protecting life on Earth from harmful effects. Human activities, such as the release of ozone-depleting chemicals, can impact the ozone layer and lead to increased UV exposure.
How tall can a Douglas-fir grow?
The Douglas-fir may reach over 300 feet tall in its native environment. Some specimens of the past rivaled and exceeded Coastal Redwood in stature:

What is the difference between Ecology and Environmental Science?
Ecology is the study of interactions between organisms and their environment, focusing on relationships within ecosystems. Environmental science is a broader field that incorporates elements of ecology but also includes the study of human impact on the environment, pollution, resource management, and sustainability. Ecology is more focused on the biological aspect of ecosystems, while environmental science encompasses a wider range of disciplines to address environmental issues.
Is carbon tetrachloride man mad or found in nature?
Carbon tetrachloride is a man-made chemical and does not occur naturally in the environment. It was historically used in various industrial applications but is now heavily regulated due to its harmful effects on human health and the environment.
How far underground can water infiltrate?
Water can infiltrate underground to various depths depending on factors like soil type, permeability, and presence of confining layers. In some cases, water can infiltrate several hundred feet underground, while in others it may only reach a shallow depth of a few feet. The process of water infiltrating underground is crucial for replenishing groundwater sources.
How did the environment effect the Cherokee people?
The environment influenced the Cherokee people through providing resources for their food, clothing, and shelter. They adapted to their surroundings by cultivating crops like corn and beans, hunting game such as deer and bear, and building homes using materials from the forests like wood and clay. The environment also played a role in shaping their cultural practices and spiritual beliefs.
What harmful effects does the jacaranda tree have on society?
The jacaranda tree is not known to have harmful effects on society. In fact, it is beloved for its ornamental beauty when in bloom and is often planted for its aesthetic value in many regions.
What are the good effects of afforestation?
Afforestation is the process of establishing a forest on land where there is no forest, by planting trees or sowing their seeds and caring continually until the trees grow collectively as a whole into a forest as planned.
Need and importance of afforestation:Afforestation helps in addressing the environmental issues of the world, esp. in preventing further global warming and reversing the effects of global warming. It also helps in avoiding desertification.
As the human needs grew by the population growth and advances in civilization people have been exploiting nature and converting forests into agricultural lands, mines, and industrial areas for various resources for their recreation, enjoyment and comfort in living.
As the global environmental issues due toindustrialization are growing more seriously, there isan urgent need for the mankind to resolve them by protecting the environment by way of afforestation.
The afforestation in and around an industrial region serves in aesthetically enhancing the foreground and background landscape features while contributing to the overall improvement of the environment.
Forests have many important and varied functions, and to have a broad idea some of them are listed below:
- Forests are the renewable resources of nature.
- They are giant sinks of carbon: they absorb and assimilate carbon dioxide, which accounts for the majority of the greenhouse gases that are now accelerating global warming.
- They are home to living creatures,
- They contribute in maintaining biodiversity
- They regulate the climate
- They provide industrial timber and fuel,
- They prevent and mitigate sudden freshets that lead to flooding
Forests are fundamentally essential in
- preservation of natural lands against soil run-off and erosion resulting in retention of fertility of the soil
- conservation of water resources,
- creating a healthy atmosphere for health of humans and other beings,
- evolution of culture and civilization
- providing research opportunities in education and learning
When we compare forest with non-forest areas within a single region, we find that forest areas are generally higher in humidity and milder in temperature. Water released from forest areas enters the sea and nurtures a wide variety of life forms naturally.
Afforestation is a proven method which contributes to environmental conservation, less-polluted industrial development and healthy community activation.
Why do we need to recycle paper?
To prevent new trees from being cut down for the paper products made from recycled newspaper .
news papers is one o f the most distributed types of so called, 'junk mail'. many people just read the paper once and then chuck it in the bin. however, if we can recycle our newspaper, then we can cut down less trees; for our environment. trees are essential for our existence (they provide us with oxygen that we breathe with), therefore we rely on them. if we didn't have trees then we would've died out. recycling is when we reuse something; it's environmentally friendly :) . think of all the trees we could save if everyone recycled their newspapers!
What are the effects of dynamite fishing in the philippines?
Dynamite fishing has many harmful effects on the environment. It not only harms the target fish, it kills everything in the blast area. It kills the fish eggs, fry, plants, and can launch sludge into the water. It can significantly harm the reproductive cycle of any species in the blast area.
What is the importance of afforestation in Nigeria?
the important of afforestation in Nigeria cannot be overemphasized. it helps in addressing the environmental and socioeconomic problems in the northern part of the country. it provides shelter as well as windbreak in the region. it provides a source of fuel wood and poles for the buildings. it also prevent desert encroachment by stabilizing the soil and reducing the speed of winds. increasing crop yield in the region cannot be ruled out, afforestation make marginal lands more arable.

First a short bit on what polyethylene is:
Polyethylene is a long chained organic molecule that is formed from ethylene (H2C=CH2).It contains no other materials than Carbon and Hydrogen. The basic building block (ethylene) is a non toxic gas that can act as a hormone in plant growth, speeding ripening and the rowth of seedlings.
The harmful effects of polyethylene are more related to the forms that it is made into - films, ropes, six-pack holders, milk jugs etc. As trash it is refractory in the environment, lasting for many years without decomposition except if it is exposed to sunlight. As trash, due to its shapes it has been observed to trap animals legs and heads.
If collected it can be easiiy recycled reducing the need for consumption of fresh raw materials and energy. If burned, it is converted to carbon dioxide and water.
Historical example of conservatism?
When you say historical, I am compelled to think of both document and event. So I shall provide an example in both situations. In the Congress of Vienna of 1815, where the Restoration of Europe began, the most important principle was legitimacy. Conservatives aimed to make legitimate both the monarchy's authority and a hierarchical social order. Conservatives wanted political stability after a period of turmoil with the French Revolution and other events of the time. And legitimacy seemed to be the best way to ensure that stability when restoring the government systems in European countries. As for the document, Edmund Burke's Reflections on the Revolution in France is a clear example of conservatism. He argued that the "conquering power of reason" was dangerous. He also saw enthusiasm for constitutions as misguided (as enthusiasm was in the French Revolution with the Reign of Terror). In his document, Burke defended experience, tradition and history.
