Smog In Los Angeles

Los Angeles is one of the most polluted major cities in the United States, behind Detroit, Pittsburgh, and Cleveland. For years Los Angeles has been covered by clouds of smog caused by an over abundance of pollution. The main cause of the pollution in Los Angeles is from the automobiles and the industrial/manufacturing of products. Over the past 100 years, the air in Los Angeles was scientifically proven to be unhealthy so, during the 1960s and 1970s, government set up laws against the amount of air pollution Los Angeles could make. Scientist found that the amount of pollution crated in Los Angeles was deadly to the O-Zone and caused a larger hole to be ripped into it.

At its peak of pollution, Los Angeles was virtually unseen from less than a mile away. The only way people could see L.A. from a distance was looking for the tops of the sky scrapers. Now, in 2011, the smog has virtually disappeared. Los Angeles can be seen from miles away now due to the strict laws to cut pollution and now that more people are going green, they cut back on the majority of pollution.

This Smog isn't just effecting the people on the west coast, this will effect the people who are back wind to them, like India and other Pacific places like China, Japan, Vietnam, and some entering the middle east. This is a problem that we must take care of, who is stopping other countries from doing the same thing to us in the United States?

Deforestation, Why it Causes Problems.

Deforestation is when humans remove a large amount of trees from forest to use as paper and many other commercial products. Deforestation effects many ecosystems and destroys them so they cannot be used by any animals again. 

Forests cover about 30% of the world's land area and is home to 70% of the worlds land animals. Tropical Rain Forests alone holds 50% of the Earths wildlife and other organisms. 90% of Earth's primates live in the Rain Forest because the canopies of the trees have perfect protection and shelter for them. If the canopies are being destroyed so fast, the primates will not be able to adapt and eventually, they will die out.

11 million acres of forest per year are cut for commercial and property industries. These industries use the trees for paper inside of their products. By making paper, they are producing a lot more pollution. Farmers also cut down many trees so they may get more land. This drives many animals out of that land and forces them to find new land, or die. 

Deforestation doesn't just effect plants and animals, it also effects humans. Trees improve the air quality. Trees absorb the carbon let out by humans and pollution and turns it all into clean oxygen. According to the Rain Forest Movement, 25% of medicines, that humans use everyday, come from forests all around the world.

Deforestation also causes climate change. Forests soil's are wet, but when the canopies are cut down, the soil loses its protection from the sun and it quickly dries out. This problem causes the water cycle to screw up because it has less water to evaporate and reuse. This can cause many deforest lands to become dry, lifeless desserts.

Why Polar Bears Are Endangered

Polar Bears live in the Arctic Circle of the Northern Hemisphere. They live in cold weather where there is plenty of ice, snow, and water. The polar bear is mostly carnivorous and they eat many things like seals and arctic foxes. They also eat berries if they can find them. There are between 22,000 and 40,000 polar bears on the Earth and over half of them live in northern Canada.


Polar Bears are endangered mostly due to the warming of the Earth. The warming causes their homes on the ice and snow to melt and they are losing food because the lack of land around them is killing the prey.


Many people are poaching, illegally hunting animals that are not supposed to be hunted, the polar bear for their fur.
