Balance is the most important factor when defining the word "nature". Each and every components and resources lies under a balanced condition. Any small change in those components will induce an imbalance in whole system of nature. Intolerable condition leads to natural hazards!
Human Activities that harm the environment
Deforestation in Increased Rate
Deforestation in Increased Rate
We have lost more than 90 percent of forest area since 1900. Man exploits Earth's forest cover for woods, buildings, land and other resources. Deforestation due to natural hazards and forest fires are termed as natural deforestation. Forest is one of the most significant factor in natural balance. Read more about impacts of deforestation.
Extreme level of carbon emission
We are largely relying on petroleum based fuels for our energy needs. Even though renewable sources of energy have been gaining more and more attention, there is no reduction in interest on petroleum based fuels. It is because of the high energy density of traditional energy sources. We know that availability of petroleum fuels are decreasing and the technology world is experimenting with renewable energy sources for sustainable energy. Burning of carbon based fuels (petroleum and coal) releases a large amount of carbon dioxide to the atmosphere. This carbon dioxide causes global warming and several other environmental issues.

Over exploitation of Minerals and Resources
We should remember that, the nature and its resources are not only for human kind but also for other living organisms. Due to the selfishness we are exploiting the nature up to maximum possible. Such an over exploitation would lead to natural imbalance. Read more about effect of over exploitation of minerals and resources.
Uncontrolled Mining of Sand fron rivers, black stone, red stone
Stone is one of the main building material. There are several types of stones that can be mined from the earth. (Example: red stone, black stone) It is sure that uncontrolled stone mining would effect the balance of earth. Think a while when mining the heart of earth. Over extraction of sand would kill rivers. Sand mining from coastal areas would reduce land area.
Hill leveling for mining, industries, road transport
Hill leveling would affect under water level destruction of habitats. Hills are very beautiful creature in nature. But we are forced to destroy that beauty for our benefits. Hills have very important roles in natural rain water harvesting and absorption.
Wet land Disappearance
Wetlands are natural resources of water, which can store a large quantity of rain water and allow it to slowly absorbed by the earth. Filling of fields to construct buildings and houses would leads to future water scarcity. Fields are resources of water. We have to maintain those precious areas.
Unsafe disposal of plastic wastes
Waste plastic covers deposited on the top layer of earth would reduce the water absorption capacity of the soil. It will alter the chemistry of the soil as well as under water level. So we have to use degradable materials instead of plastics.
