Deforestation
Deforestation is occurring around the world today, and it is permanently killing forests and woodlands in many countries, but especially in the tropical areas of the world. Logging is a major contributor to deforestation, (Stock and Rochen), but cattle ranching, agriculture, and building can all lead to deforestation, as well. In addition, most of the deforestation occurs in the tropics, and the tropics have very poor soil for agriculture, when the forest is cleared for agriculture, the crops quickly deplete the soils nutrients, and more forest must soon be cleared to continue the growth. Thus, it is a never-ending cycle of clearing and deforestation. Acid rain can also lead to deforestation, and climate change could lead to more deforestation in other areas of the globe, as well.
Deforestation affects the globe in many ways. When a tropical forest is lost, the other plants and animals that depend on the forest for their survival are displaced, and this can lead to extinction. In addition, trees take in carbon dioxide (CO2) and release oxygen. Without this carbon cycle, more CO2 remains in the air, which can lead to more greenhouse gases in the atmosphere, a major cause of climate change. Deforestation can also lead to soil erosion, and more silt in rivers, streams, and behind dams throughout the deforested area. Biological diversity, including many unique species and ecosystems are lost, as well.
IN order to stop deforestation, people must be more aware of the problem and stop using products made from wood, such as paper, cardboard, and other products. We also need to find alternatives for wood products, such as the recycling of paper and wood products, and building materials such as steel, and products like Trex, which is a non-wooden material used for outdoor decks and such. To stop deforestation, we have to stop cutting down trees. Replanting deforested areas does not help, because it takes too long for the trees to grow, and the damage cannot quickly be repaired.

Environmental Science Minerals Minerals play a very important part in society, in terms of both the economy and health. People use minerals to stay healthy by means of food supplements. Minerals are also present in foods that people eat. Minerals also play a very important part in the mining industry and in the economy. According to the Mine-Engineer.com (2011) Website, the mining industry in the United States includes 140,000 employees. Metallic minerals can
Thos facilities that come in under that allowable limit because of air pollution control systems can then sell their leftover allowances to other facilities and organizations on the open market. This allows the facilities that buy up such allowances or pollution credits to pollute more, because other facilities are polluting less. This type of system has some potentially good points, by rewarding facilities that control air pollution and providing
Switching to solar heating would make a profound change, for heating and hot water can be heated freely and cleanly from the sun. By switching to energy efficient heating, air-conditioning and refrigeration, the greatest power users, consumers could have a huge impact on emissions. Changing to hybrid, fuel-efficient cars, public transportation and walking, when feasible, would have a profound impact on human-created carbon emissions. Penalizing and rewarding consumers and
Current estimations are that there is only 30 cents per person being spent by the Mexican government to combat deforestation efforts (Peters, 2002). It will be important for the government to invest more money and sustain that investment for years as it takes 15 to 20 years to re-grow some of the hardwoods currently being threatened by the deforestation process (Peters, 2002). This problem can be dealt with locally through government programs
The 1980s (the period when Ronald Reagan was the U.S. President) witnessed a series of government measures targeting environmental regulations. This resulted in public outrage against the anti-environmental policies of the government leading to a renewed interest in nature clubs and groups and the formation of radical groups who led strong movements to protect the environment.

Environmental Economics Economics and Nature Conservation From early childhood, one is taught of the importance of the surrounding environment in all human activities. Forests for instance are crucial sources of fresh air and clean water, as well as raw commodities that support life. Nevertheless, mankind continues to trash the woodlands, and as such jeopardize the future of the next generations. In a context in which next to 5 million hectares of forests
