Forest Conservation and Effects of Deforestation on Environment

Introduction

Forests are essential to human life due to the diverse materials they provide. They produce oxygen, which is required for life on Earth, act as a carbon sink, and store carbon, earning them the moniker “earth lung.” Furthermore, they regulate the hydrological cycle and the global climate; purify water; provide habitat for wildlife, reduce global warming, absorb harmful gases, and perform numerous other functions. More trees are planted, and wooded areas are maintained through forest conservation to ensure their sustainability for future generations. But it has become crucial to protect forests around the world due to rising deforestation operations. Deforestation is the permanent removal or destruction of forests to make way for new agricultural, livestock, or other uses of the land.

Some reasons why forests are essential to our survival.

The sustainable production of wood and timber products, as well as the provision of food, housing, and energy, is one of the most important functions of forests. They provide critical ecosystem services for human well-being, such as-

1. Forests cover one-third of the Earth’s land area. They carry out critical tasks all over the world.

2. The forest absorbs damaging greenhouse gases that lead to climate change.

3. Forests provide clean water for drinking, bathing, and other household needs. They help to maintain the balance of oxygen, carbon dioxide, and humidity in the atmosphere.

4. Forests provide numerous environmental, economic, social, and health benefits.

5. Forest is distributing food and medication. Forests provide safety, employment, and housing for communities that rely on them.

6. Forest cover mitigates floods and other natural disasters.

7. Forests are critical in our efforts to adapt to and mitigate climate change.

8. More than half of the world’s land-based species live in forests. Woods have the most biologically diverse ecosystems on land.

9. Many of the disease-treating medications sold around the world are made directly from plants found in rainforests.

10. Forests produce rubber, lac, organic pigments, gum, resins, and other materials.

Forest conservation

Forest conservation does not imply that users should be denied access, but rather that access should be granted in a way that does not harm the environment or our economy. The following methods might be applied to preserve forests, which would eventually enhance forested areas and ensure the sustainability of the available resources:

1. Afforestation is the practice of planting trees for monetary gain. Instead of removing trees from naturally existing forests, a practice known as “afforestation” is used to establish them and use them as resources.

2. Forest fire suppression: Forest fires are the most common and lethal cause of forest loss. As a result, precautions must be taken in such cases. Making fire lanes, using fire-fighting chemicals, removing dead trees and dry leaves, and so on.

3. Addressing the root causes of deforestation: If we are to effectively expand the role of forests in providing for basic human needs, we must address the root causes of deforestation, such as poverty and the need for food, shelter, and fuel.

4. Verifying forest clearances for urbanization: In an era of rapid urbanization and industrialization, it is common practice to remove forests through encroachment or authorization. As a result, strict regulations should be put in place to prevent the urbanization of forest areas.

5. Examining the forest harvesting procedure: To ensure successful in-situ conservation of biological diversity during forest exploitation, current forest harvesting procedures should be critically evaluated by the provisions of the Convention on Biological Diversity.

How can we protect wildlife?

Wildlife conservation refers to the process of protecting plant and animal species as well as their habitats. Wildlife conservation is a response to the century’s steadily increasing rate of extinction. Humans are to blame for the current rate of species extinction. However, we remain optimistic that we can save our species by taking a few critical steps. These are

1. Speak up for wildlife: your voice matters! Encourage your state and federal representatives to support wildlife protection legislation in writing.

2. Planting native plants is a great way to make our yards more wildlife-friendly. This provides food, shelter, and a place for wild animals to raise their families.

3. Ecosystem protection: One of the simplest and most effective ways to help wildlife is to preserve the environment in which it lives. The three major environmental conservation methods are to reduce, reuse, and recycle.

4. Be an informed consumer: Avoid using items that endanger wildlife and their habitats, such as non-recycled paper products, gas-guzzling cars, and so on.

5. Preserving endangered species: The Endangered Species Act has proven to be a successful safety net for threatened species, saving more than 98 percent of the animals it has cared for from extinction.

What if all the forests are destroyed?

It is impossible to imagine our existence without forests. The following are some consequences of destroying the entire forest:

1. The amount of  in the \(C{O_2}\) atmosphere will increase. As a result, the Earth’s temperature will rise.

2. Many animals and plants are losing their natural habitats. If they cannot find a suitable environment to live in, they may eventually die or become extinct.

3. The soil dries out without trees, and the water cycle is disrupted. Rain will cause flooding because the land cannot hold the water.

4. We will not receive valuable forest products. Tribal members may also lose their source of income.

Summary

More trees are planted, and wooded areas are maintained through forest conservation to ensure the sustainability of wooded regions for future generations. We can rely on forests for shelter, work, water, food, and fuel security, among other things. The practice of preserving plant and animal species, as well as their habitats, is known as wildlife conservation. We, humans, have a responsibility to protect our species by taking a few key actions.

Frequently Asked Questions

1. What are the negative consequences of deforestation?

Ans. In addition to harming the environment, society, and especially the climate, biodiversity, and poverty, deforestation has a negative economic impact.

2. What exactly is the Global Forest Carbon Mechanism (GFCM)?

Ans. The Global Forest Carbon Mechanism is a financial structure that would reward developing countries for reducing their emissions.

3. How can we ensure food security while also halting deforestation?

Ans. The increased agricultural output should be achieved without cutting down more trees. Better land design and significant investment are required to increase yields on existing farmland.

Ecosystem- Abiotic factors

Introduction

The ecosystem is defined as a geographical area composed of living beings and non-living beings interacting with each other. Both of them are interdependent and hence together are responsible for maintaining the balance of the environment. Living beings in an ecosystem are termed biotic factors; they include microbes, plants, and animals. Non-living beings of an ecosystem are known as abiotic factors and they are physical or chemical non-living components of the ecosystem. These factors are essential for the survival of living organisms in the given ecosystem. They determine the structure, growth pattern, distribution, and behaviour of the living organism in an ecosystem. These factors include temperature, light, humidity, water, air, land, soil, pH, etc.

Types of Abiotic Factors

There are 3 types of abiotic factors-

  • Inorganic compounds-Compounds and elements which are a part of various biogeochemical cycles are the inorganic compounds found in the ecosystem and they are very essential for the biotic components. Nitrogen, phosphorus, carbon, and other elements are examples of inorganic materials.
  • Organic compounds- These are the substances that are present in dead and decaying organisms. These include biomolecules like lipids, proteins, and carbohydrates. These organic components are broken down into simpler compounds such as carbon, hydrogen, oxygen, and nitrogen which circulate in the ecosystem and nourish various abiotic factors such as soil, air, water, etc.
  • Climatic and soil factors-These variables include the ecosystem’s physical elements, such as temperature, humidity, light, air, and soil. Climate variables are those that affect the weather or climatic condition of the ecosystem, whereas edaphic factors are those that affect the qualities of the soil, such as pH and topography.

Ecosystems Based on Abiotic Factors

Abiotic elements found in a given habitat can be used to categorize ecosystems.

  • Aquatic ecosystem- An ecosystem is said to be aquatic if both its biotic and abiotic components are found in water. Depending upon the salinity of the water, aquatic ecosystems can be of two types- Freshwater ecosystems and Marine ecosystems.
  • Terrestrial ecosystem- An ecosystem is referred to as a terrestrial ecosystem if the biotic and abiotic components reside on the land. Depending upon various factors such as availability of water, climatic conditions, and temperature. Terrestrial ecosystems can be of 4 types- Forest, Grassland, Mountain, and Desert ecosystem. 

Responses of Organisms Against Changes in Abiotic Factors

Biotic factors that inhabit a certain habitat react with the abiotic elements present there.  Hence, the abiotic factors become stimuli which results in the display of various effects on different organisms. Below are a few examples 

  • Homeostasis-Homeostasis is the process by which the interior environment of organisms is maintained in a steady state, despite various external changes. Organisms can be divided into two categories: 
    • Regulators-These species can use energy to maintain homeostasis. They are active, widely dispersed, and maintain a steady internal body temperature and osmotic concentration. For e.g.- Birds and mammals.
    • Conformers- These species are unable to maintain homeostasis and hence can survive only in specific conditions. For eg- Fish, amphibians, reptiles, etc.
  • Migration– Migration is the movement of living creators from one place to another. Such creatures temporarily migrate to a suitable location when there are unfavourable conditions in their native habitat. They return to their former habitat as soon as the environment is normalized. For example-  To avoid the severe winter climate, birds from Siberia travel to India.
  • Suspension- When faced with unfavourable circumstances, certain species briefly halt their continuous metabolism i.e they suspend their growth and development for a while. For eg- Spores are formed by fungi and bacteria which can withstand severe conditions. Plants produce seeds that have a thick seed coat and a period of dormancy. While snails and frogs become dormant in the summer, bears hibernate during the colder months.

Summary

Abiotic elements are the nonliving parts of an ecosystem that surround living ones in any habitat. Both aquatic and terrestrial habitats include them. The biotic components are occasionally impacted by changing abiotic variables. To ensure their existence, these biotic components have a variety of strategies to deal with changes in these abiotic conditions.

Frequently Asked Questions

1. What is a Local and Global Ecosystem?
Ans: A local ecosystem consists of different types of habitats along with living organisms. A global ecosystem is a group of many local ecosystems.

2. What is Diapause?
Ans: Diapause is a response given by organisms under unsuitable environmental conditions. It is a spontaneous phenomenon wherein there is an interruption in the developmental stage of an organism due to changes in the abiotic factors. For instance, the monarch butterfly goes through reproductive diapause to get ready for its migration from North America to Mexico between late summer and fall.

3. What are the Abiotic Factors in a Forest Habitat?
Ans: The abiotic factors of forest habitat are-

  •  Soil
  •  Temperature
  • Humidity
  • Rocks
  • Water

4. Give one Example of a Plant’s Response to Abiotic Factors of the Environment.
Ans:
One example of a plant’s reaction to the abiotic component of light is phototropism. In contrast to the root, which grows away from the light source and exhibits negative phototropism, the plant’s shoot grows in the direction of the source of light and shows positive phototropism.
