Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows, but it can’t get back out. This is what the greenhouse effect does to the earth. The heat and light can get through the atmosphere, but it can’t get out. As a result, the temperature rises.
The sun’s heat can get into the car through the windows but is then trapped. This makes whatever the place might be, a greenhouse, a car, a building, or the earth’s atmosphere, hotter. Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it, the earth would be freezing, or on the other hand it would be burning hot. It would be freezing at night because the sun would be down. We would not get the sun’s heat and light to make the night somewhat warm. During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it, so people, plants, and animals would be exposed to all the light and heat.
Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses. We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and making many other things. Although this source of energy gives off a lot of pollution, Some examples of using energy and polluting the air are:
Turning on a light
Washing or drying clothes
Using a hair dryer
Riding in a car
Heating a meal in the microwave
Using an air conditioner
Playing a video game
Using a dish washer
* Consider investing in a hybrid or electric vehicle to help prevent against further global warming. * Replace all the light bulbs in and around your home with energy-efficient fluorescents that use fewer watts for the same amount of light. * Choose energy efficient appliances when it’s time to buy new ones * Decrease your air travel. * Wash clothes in cold water and line-dry whenever possible * Buy recycled paper products and recycle your waste products as much as possible.[A diagram that depicts the greenhouse effect]
Deforestation is when humans remove or clear large areas of forest lands for non-forest use. These include clearing for farming purposes, ranching and urban use. In these cases, trees are never re-planted. Since the industrial age, about half of world’s original forests had been destroyed and millions of animals and living things have been endangered. Despite the improvements in education, information and general awareness of the importance of forests, deforestation has not reduced much, and there are still many more communities and individuals who still destroy forest lands for personal gains. Soil erosion:-
Soils (and the nutrients in them) are exposed to the sun’s heat. Soil moisture is dried up, nutrients evaporate and bacteria that help break down organic matter are affected. Eventually, rain washes down the soil surfaces and erosion takes place. Soils never get their full potential back.
When forests are destroyed, the atmosphere, water bodies and the water table are all affected. Trees absorb and retain water in their roots. A large part of the water that circulates in the ecosystem of rainforests remains inside the plants. Some of this moisture is transpired into the atmosphere. When this process is broken, the atmosphere and water bodies begin to dry out. The watershed potential is compromised and less water will runs through the rivers. Smaller lakes and streams that take water from these larger water bodies dry up.
Sometimes, we are overwhelmed by the extent of damage humans have caused, and we are not sure if an individual can make any impact. Well, yes, there are millions of people just like you, who are learning about the issue and taking little steps to help. Additionally, many governments, organisations and societies are making great strides in helping reducing deforestation, and encouraging forest plantation. But there is still a lot to do Due to the extent and nature of forest destruction; efforts to stop deforestation and preserve forests are best achieved at government and organization levels. This means that laws, rules and regulations from countries can help to enforce the preservation of forests.
Laws on farming, timber and wood, as well as land use must be encouraged and enforced. There is a fun way to remember the most important points in forest preservation called TREES which means… * Teach others about the importance of the environment and how they can help save rainforests. * Restore damaged ecosystems by planting trees on land where forests have been cut down. * Encourage people to live in a way that doesn’t hurt the environment * Establish parks to protect rainforests and wildlife
