Deforestation and Green House Effect
- 3. What is Deforestation? Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a non- forest use. The removal of trees without sufficient reforestation has resulted in habitat damage, biodiversity loss, and aridity. It has adverse impacts on bio sequestration of atmospheric carbon dioxide.
- 4. What is Green House Effect? The greenhouse effect is the process by which radiation from Earth’s atmosphere warms its surface to a temperature above what it would be without its atmosphere. Human activities like the burning of fossil fuels and clearing of forests, have strengthened the greenhouse effect and caused global warming. The term "greenhouse effect" arose from a faulty analogy with the effect of sunlight passing through glass and warming a greenhouse.
- 5. Impact on the climate, environment and human life Deforestation can have a negative impact on the environment. The most dramatic impact is a loss of habitat for millions of species. Deforestation also drives climate change. Forest soils are moist, but without protection from sun- blocking tree cover, they quickly dry out.
- 6. Some More..... 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.
- 8. Effects of Deforestation in India In India alone, one million hectare of forest is being cut down. The pressure of urbanization, the growing population and the craving for the rapid development have deprived us of green cover. For India, the area-averaged annual mean warming by 2020 is projected to be between 1.0 and 1.4°C and between 2.2 to 2.9°C by 2050. Relatively, the increase in temperature would be less in kharif than in rabi. Increase in temperature, can reduce crop duration, increase crop respiration rates, affect the equilibrium between crops and pests, hasten nutrient mineralisation in soils, decrease fertiliser use efficiencies, and increase evapo-transpiration among others.
- 9. Reducing the Effect There are several ways to reduce deforestation and green house effect. But for that we not only have to work with society but also alone in many ways like, if we cut one plant/tree we should plant two more. In the following slide, there are some ways to reduce this effect
- 10. These are 10 ways to protect the ENVIRONMENT
- 11. 04 Drive Less and Drive Smart Save petrol by walking or cycling. When you do drive, make sure your car is running efficiently. 03 Replace your Light Bulbs Whenever possible try to replace incandescent bulbs with CFLs or LEDs 05 Buy Energy-Efficient Products Home appliances now come in a range of energy-efficient models.
- 12. 06 Use Less Hot Water That change alone can save at least 500 pounds of carbon dioxide annually in most households. 07 Using the OFF Switch Reduce global warming by turning off lights when not in use, and using only as much as you need. 08 Plant a tree A single tree will absorb approximately one ton of carbon dioxide during its lifetime.
- 13. 09 Get a Report Card from your Utility Company Many utility companies provide free home energy audits to help consumers identify areas in their homes that may not be energy efficient.
