Habitat Destruction:

 * Most threats to habitats are caused by humans.
 * Habitats are destructed mainly for agricultural purposes such as forestry, this is also called deforestation.
 * Climate change is affecting habitats everywhere

Desertification:

 * Deserts are being used as dump sites for nuclear waste.
 * Because desert plants (like cacti) are rare, people often seek them for household decorations. This takes the plants away from their natural habitat, also taking away nutrients from the soil.

Some of the issues that the Gobi Desert is facing are:

 * Farming; as our population increases farmers will have to produce more crops to feed everyone. This causes the land to turn dry and take away proper nutrients in the soil which can lead to desertification.
 * Over grazing; using improper grazing techniques can cause the livestock to eat all of the grass and shrubs.
 * Climate change; climate change causes strong winds to occur unexpectedly and blows sand everywhere. Increase in global temperature causes less rain to fall, therefore the crops don't get the things that they need to grow and survive.

Deforestation:

 * Cutting down trees for human use ruins animals natural homes.
 * This also reduces the amount oxygen being released into the air.

Coral Reef Destruction:

 * Coral reefs everywhere are being destructed due to tourism, pollution, and other factors/
 * Scuba divers and snorkelers also damage aquatic ecosystems.

Habitat Destruction-
Habitat destruction is one of the biggest issues that the world is facing today. Climate change and human activity are the two main factors as to why this is happening. Habitat destruction not only takes away habitats from our world, but also destroys animal's homes. This also leads to species endangerment. Humans destroy habitats for industrial and agricultural purposes.There are many types of habitat destruction such as desertification, deforestation, water issues, weather issues, climate change, and species endangerment.

Desertification -
Deserts everywhere are expanding, especially the Gobi Desert. They expand because of climate change [strong winds] and human activity. Some governments have been trying to stop desertification by planting trees and doing other things. Climate change affects deserts because as the climate increases, there is less rainfall. It also causes changes in weather, which makes strong winds occur unexpectedly. Humans affect desert by overgrazing or using improper grazing techniques. If we do things to stop all of the issues from happening then the world will be a better place for us and the generations to come.
