Decrease on forest layers (flora may even suffer extinctions)
Makes ecosystem less stable and more vulnerable to diseases, competition, and extinction (ecosystem would collapse)
Depletion of the region’s genetic bank (many species are endemic to the rainforest areas)
Increased levels of CO2 (higher amount of greenhouse gases-> higher Global Warming)
Reduced levels of O2 (rate of photosynthesis is reduced)
Decreased precipitation due to a reduced vegetation cover
Reduced interception capacity leading to greater likelihood of flooding
The ultimate alteration of the Amazon’s and other tropical rainforest’s discharge regime and sediment transport pattern
Severe soil exhaustion and erosion
The adverse impact on the indigenous population
And how to fix them… Chapter 55. In the past – deciduous forests have been impacted Today, it is more a problem in the tropics Subsistence agriculture.
Rainforests are the most diverse biomes in the world. Is preserving this biodiversity important? Why or why not?

Environmental Concerns CH 6.4. Global Warming Definition: Overall rise in Earth’s temperature Cause: Increase in CO 2 other greenhouse gases Effect:
Global Warming. What is Global Warming? Global warming is an increase in both land and sea temperatures. Global warming is caused by an increase of CO2.
Water Cycle – Humans alter by: 1.We withdraw large quantities of fresh water. 2.We clear vegetation and increase runoff, reduce filtering, and increase.

Chapter 5 Biodiversity & Conservation. Biodiversity is the variety of life in an area that is determined by the total number of different species. Biodiversity.
The Tropical Rain Forest How can such productive forests grow on soils of extremely low fertility? Why is biological diversity so high in the tropics?
Carbon Cycle. What is the Carbon Cycle? In the carbon cycle, carbon is transferred from inside the Earth to the atmosphere, oceans, crust, and to living.
Biota- all of the living parts of the biosphere Hydrosphere- all of the water in its various forms in the biosphere Atmosphere- the air surround.
Impact of Global Warming Sea level rising Altered precipitation pattern Change in soil moisture content Increase in some extreme weather More flood more.
