Human Impact on nature
Human activities that affect the environment:
State of ecosystems, habitats and species
Modern agriculture is responsible for the loss of much wildlife and their habitats
The drainage of wetlands, the destruction of hedgerows and the intensive use of fertilizers and pesticides may represent a threat to wildlife.
Highly specialized monoculture are causing significant loss in species abundance and diversity.
Increased production per hectare in intensive areas, raising of livestock volume, and lower prices for agricultural products result in intensive agriculture and abandoned land.
Our world is...
• a resource for food supply
• an energy source
• a source for recreation
• a major source of medicines
• natural resources for industrial products
overuse of pesticides and herbicides
intensive farming methods
general human disturbance
Loss of Species of Fauna
All energy types have potential impacts on the natural environment to varying degrees
They are used as fuels to create motion or heat.
“Human influence on Earth can be positive or negative, benign or catastrophic. Recognizing this responsibility is the first step each of us can take to transform the human footprint and save he last of the wild.”
Dr. Eric W. Sanderson

Wild fish capture
They lead to...
Agriculture (pesticides and fertilizers)
Almost all forms of industry have an impact on the natural environment and its sustainability.
