Haze is the blurriness caused by stagnant air pollution. It leads to reduced visibility, and is most common metropolitan cities

Air pollution causes acid rain, which leads to erosion of trees, statues and even buildings

Air pollution causes an excess of nitrogen in lakes, also known as eutrophication. This leads to an abundance of algae and a decrease

Ozone depletion increases the amount of UV that reaches Earth's surface.

As time goes on, humans are moving away from rural areas and towards urban areas. This means that large amounts of natural resources must be used to fuel the ever-growing population

Also referred to as climate change, global warming is the rise in the average temperature of the Earth's climate

It occurs when carbon dioxide, greenhouse gases, and other air pollutants collect in the atmosphere. They absorb solar radiation, and trap the heat (greenhouse effect)

Naturally, the destruction of habitats leads to a loss of species. In fact, from 1970 to 2010, we have seen a 52% percent decrease in wildlife population. Scientists predict this number will rise to 75% by 2050

1. Rising temperature
heat waves, droughts, hurricanes
2. Rising sea levels
tropical storms, floods
3. Other
disruption of coral reefs, wildfire

Although we have contributed negatively to the environment in many ways, we have found a way to reduce our carbon footprint

It is very likely that alternative energy could be the future. This type of energy harnesses natural resources without depleting them, making it a win-win situation for us and the environment

# data[].attributes.body
So far, we have done some large-scale changes to the environment. These include a loss of species, an overall increase of temperature and even a depletion of natural resources

Globalization will continue to happen. However, if we take small steps today, they can lead to a big change in the future. We have to take steps now if we want future generations to live in a hospitable environment

Clear cutting is a method that timber companies use to log forests. Timber harvesters cut down and remove every tree from and area.

1. Regenerates the forest with healthier trees
2. Provides new habitats for animals (although it takes some time)
3. Increased water flow
4. Increased farmland

1. Global Climate Change
2. Loss of species ( habitats )
3. Soil Erosion
tree roots anchor the soil

1. Destruction of plant life and animal habitat
2. Soil damage
3. Flooding
4. Diseases from mosquitoes (clear cutting provides places to live for mosquitoes)
