Which it is the environmental impact of cutting down trees and what their solutions

Answers



Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area, but swaths the size of Panama are lost each and every year.

The world’s rain forests could completely vanish in a hundred years at the current rate of deforestation.

Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families.The biggest driver of deforestation is agriculture. Farmers cut forests to provide more room for planting crops or grazing livestock. Often many small farmers will each clear a few acres to feed their families by cutting down trees and burning them in a process known as “slash and burn” agriculture.

Logging operations, which provide the world’s wood and paper products, also cut countless trees each year. Loggers, some of them acting illegally, also build roads to access more and more remote forests—which leads to further deforestation. Forests are also cut as a result of growing urban sprawl.

Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees.

Deforestation has many negative effects on the environment. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.

Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor back into the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts.

Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and holds in heat at night. This disruption leads to more extreme temperatures swings that can be harmful to plants and animals.

Trees also play a critical role in absorbing the greenhouse gases that fuel global warming. Fewer forests means larger amounts of greenhouse gases entering the atmosphere—and increased speed and severity of global warming.

The quickest solution to deforestation would be to simply stop cutting down trees. Though deforestation rates have slowed a bit in recent years, financial realities make this unlikely to occur.

A more workable solution is to carefully manage forest resources by eliminating clear-cutting to make sure that forest environments remain intact. The cutting that does occur should be balanced by the planting of enough young trees to replace the older ones felled in any given forest. The number of new tree plantations is growing each year, but their total still equals a tiny fraction of the Earth’s forested land.
Oxygen! We breath it.
Trees make it! No trees! no fresh air! Hhard to breath! Mote carbon dioxideb left not processed by trees and plants. Solution: balance the amount of trees cut down with planting of new trees in places or areas they have been cut down. Get the world to agree that chopping down trees just to chop without considering the environmental impact and Global Warming effects should be planned and measured so we have lots of oxygen. Trees help clean the air.?

What really is a computer, using technical terms of course, and what is a byte/bit?

Answers

Assuming that you mean a modern digital computer, a computer often has different definitions in the computer field on what makes a computer. Based on facts and my opinion, a computer is a something that can be programmed, give output and receive input, has a function, and to an extent, has mechanical hardware. In other words, its something that has both hardware and a sort of software. A bit and a byte are different. A bit is the basic unit of memory in computers. A byte consist of 8 bits or more known as an octet. The term octet is often used in IP addresses but that is another long matter. So in other words, anything with memory capability such as RAM, SDD, Hard drive, Flash drive (USB), and CD/DvDs, all have bits/bytes in them.
