what causes salinization?

Poor drainage, semi-arid or arid region of the world, water table 2-3 meters from the surface are some of the reasons. You can go to www.google.com and type in salinization. There are a number of articles there worth reading.

need an example to understand how topographical factors intensify air pollution and how they can help pollution?

I have a project due in a three weeks and I am trying to get a head start on this.Here is the project and My Ideas I am needing where I can get some facts and figures to prove my point but i got lost on a few Ideas if anyone can help with a few ideas or sites I would appreciate it THANK YOU
importance of biodiversity.
The powerpoint presentation with notes.
I have to choose a Region?

Which I Live in the Mid_Atlantic Region of the United States So I decided I should learn more about it.
I Have to show the causes of wildlife extinction as well as demonstrate ways wildlife extinction impacts our world.

In Which Human Through Deforestation is how I feel is the biggest problem if I am wrong please tell me.

outlining the causes, be sure to show the relationship between the deforestation and wildlife extinction in Mid- Atlantic Region and the world. I need to show estimations of the current and potential impact of deforestation on world.

Show the aquatic life zones. Lost for Ideas on this one?
implemented to preserve the present level of aquatic biodiversity.

To find information and data for your project, you can start by conducting an internet search using keywords related to each topic. Here are some steps to help you gather information for your project:

1. Importance of Biodiversity:
- Begin by searching for scientific articles, research papers, and reputable websites that provide information on the importance of biodiversity.
- Check scientific journals such as Nature, Science, or Conservation Biology for relevant studies.
- Websites like the World Wildlife Fund (WWF) or the United Nations Environment Programme (UNEP) may also have valuable information.

2. Mid-Atlantic Region and Deforestation:
- Start by researching the Mid-Atlantic Region's specific characteristics, such as its geographical features, climate, and wildlife.
- Look for reputable sources that describe the deforestation challenges and patterns in this region. Websites like the United States Environmental Protection Agency (EPA) or the National Park Service can provide relevant information.
- Search for studies or reports that discuss the relationship between deforestation and wildlife extinction, both globally and specifically in the Mid-Atlantic Region.

3. Estimating the Impact of Deforestation on the World:
- Look for scientific papers or reports that provide estimates on the current and potential global impact of deforestation.
- International organizations like the Food and Agriculture Organization of the United Nations (FAO) or the Intergovernmental Panel on Climate Change (IPCC) may have relevant data.
- Consider looking into satellite imagery or mapping tools that show the extent of deforestation in different parts of the world.

4. Aquatic Life Zones and Conservation Measures:
- Research the different aquatic life zones found in the Mid-Atlantic Region, such as rivers, lakes, estuaries, and coastal areas.
- Look for scientific literature and resources that describe the biodiversity and ecological importance of these aquatic ecosystems in the region.
- Investigate conservation measures and initiatives that have been implemented to preserve aquatic biodiversity in the Mid-Atlantic Region. Check organizations like the Chesapeake Bay Program or local conservation groups for information.

Remember to critically evaluate your sources to ensure they are reliable and accurate. Use academic databases like Google Scholar or resources from reputable organizations. A combination of scientific literature, reports, and government websites should provide you with the necessary facts and figures for your project.
