Deforestation‚ is on a human scale results in decline in biodiversity‚ and on a natural global scale is known to cause the extinction of many species. The removal or destruction of areas of forest cover has resulted in a degraded environment with reduced biodiversity. Forests support biodiversity‚ providing habitat for wildlife; moreover‚ forests foster medicinal conservation. With forest biotopes being irreplaceable source

As you have learned in the readings‚ extinction is a natural selection process. You have also read that humans are often responsible for accelerating this process. Using at least two scholarly or reputable resources and your textbook‚ address whether or not we as humans should be concerned with the extinction rate. Additionally‚ discuss whether or not humans should strive to preserve representative samples of all biomes on the planet. Yes‚ I believe that humans should be concerned with the extinction

Chapter 4 – Conservation and biodiversity Definitions: Species: A group of organisms that interbreed and produce fertile offspring e.g. horses and donkeys Population: A group of organisms of the same species living in the same area at the same time‚ and which are capable of interbreeding Biodiversity: The amount of biological or living diversity per unit area. It includes the concepts of species diversity‚ habitat diversity and genetic diversity. Species diversity: Both the range and

In practice‚ "biodiversity" suggests sustaining the diversity of species in each ecosystem as we plan human activities that affect the use of the land and natural resources. 1. Species diversity 2.

continuing problems of pollution‚ loss of forest‚ solid waste disposal‚ issues related to economic productivity and national as well as ecological security. The increasing levels of global warming‚ the depletion of the ozone layer and a serious loss of biodiversity have also made everyone aware of growing environmental concerns.

Its biodiversity is among the richest on the planet‚ with over 250‚000 species across the island. Most of that biodiversity is found in the tropical rainforests that cover most of the Eastern half of the island. What really makes Madagascar’s biodiversity unique is that almost 175‚000 (75%) of those species are only found on this island. There are an estimated 12

humans also live on the Earth and we will be highly affected by a mass extinction. Biodiversity is extremely important to the functionality of an ecosystem. It allows for food security for animals‚ including humans. It also is important for resilience. If an ecological disturbance were to happen such as a drought‚ flood‚ or disease‚ resilience is the ability of an ecosystem to recover from that disturbance. Biodiversity is key to resilience since species can shift their roles in an ecosystem and this

DEFORESTATION AND SPECIES LOSS 1.0 WHAT IS DEFORESTATION? Deforestation is the process whereby natural forests are cleared through logging and/or burning‚ either to use the timber or to replace the area for alternative uses. 2.0 WHAT IS THE EXTENT OF DEFORESTATION? 12-15 million hectares of forest are lost each year‚ the equivalent of 36 football fields per minute. 3.0 WHAT ARE THE MAJOR CAUSES OF DEFORESTATION? Deforestation can happen quickly‚ such as when a fire sweeps through the
