Why is deforestation happening?

Extracts from this document...

Introduction

Deforestation Fion Lai Food is one of life's basic necessities. People produce them around the globe by using a wide variety of agricultural practices. Hence, agriculture is one of the biggest businesses in the world. However, human activities always affect the balance of the ecosystem. Forest is a valuable community of the biodiversity. It contains high diversity, with complex food webs - it contains a large gene pool of plant and animal resources. Also, it plays a very essential role in converting carbon into the way that organisms can absorb. It also converts the nutrients in soil for organism and prevents erosion in regions of high rainfall. The growth in human population increases the demand of land of farming. This causes deforestation. Deforestation upset the whole ecosystem. ...read more.

Harvesting takes away the nutrients from the soil, crops are harvested before they die and decompose in the soil. Farmers then add fertilizers in the soil to provide more nitrite ions for the crops to grow. However, the nitrite ions in the fertilizers are highly soluble and can easily leach into the rivers or seas. This causes eutrophication and leads to many death of organisms. Human societies are concerned with global warming, deforestation, species extinction, the limits to long-term productivity and rising expectations. We understand the importance of healthy forests in our living planet. But the growing populations must be fed, clothed, and sheltered. Today, sustainability is a vital issue in forestry. When agricultural operations are sustainably managed, they can preserve and restore critical habitats and improve soil health and water quality. ...read more.

Conclusion

b) Clearcutting - In clearcutting, an entire stand of trees is removed in one operation. Regeneration may come from sprouts on stumps, from seedlings that survive the logging operation, or from seeds that germinate after the harvest. If natural regeneration is delayed longer than desired, the area is planted or seeded. c) Shelterwood - In shelterwood systems, the forest canopy is removed over a period of years, usually in two cuttings. After the first harvest, natural regeneration begins. By the time the second harvest is made, enough young trees have grown to assure adequate regeneration. Shelterwood systems favor species that are intermediate in tolerance to shade. In conclusion, conversation of forest is important and urgent. There is no easy solution as deforestation is caused by many factors. But for definite, decreasing the amount of use of products that are harvested from the rainforests and using recycling products help. The continuel deforestation wil only bring a severe consequence. ?? ?? ?? ?? 1 ...read more.
