Humans can affect the nature in a negative way by polluting, waste dumping, overhunting and overfishing, consuming scarce energy resources. Greatest threats to the human species are man-made.
We are currently facing several environmental problems such as deforestation, loss of biodiversity, disposal of waters, air pollution, habitat loss for wildlife, water pollution, species extinction. Environmental problems are major risks to human health.
Across half of the Earth’s land surface, biodiversity – all the different animals, plants, and other species that make up the ecosystem- has decreased below “safe” levels.
Natural ecosystems have lost about half their area and millions of species are at risk of extinction – all largely as result of human actions. We are eroding the very foundations of life.
It’s overwhelming how much biodiversity has been lost all over the world, as more and more land is changed by people – turned into pastures, fields, or cities. 37% of the Earth’s land (2017) is used for agricultural purposes, yet an estimated 1/3 of all food produced globally is lost or goes to waste (1.3 billion tones of food a year).
