What happens if we do nothing for the environment?
Protecting the environment means protecting people If we protect nature, we are also protecting our own survival. A lack of natural resources, such as a shortage of drinking water, encourages crises and wars. And even the smallest changes in the ecosystem can have major effects.
What is bad for the environment?
Industrial production causes environmental damage by polluting water, soil and air. Raw materials and energy are consumed during production, and waste is produced. The industrial products are transported to the consumers; environmental pollution caused by traffic.
What are the main air pollutants?
Air consists of nitrogen (N2) and oxygen (O2). Even small particles (fine dust) pollute the air. Sulfur dioxide (SO2) is produced when sulphurous fuels such as coal and heavy oil are burned.
Which pollutants are produced by cars?
But cars not only emit CO2, but also many other pollutants – for example carbon monoxide, nitrogen oxides, sulfur dioxide, soot particles. Since 2005, new petrol engines have been allowed by law to emit no more than one gram of carbon monoxide per kilometer, diesel a maximum of 0.5 grams.
Organic pollutants, especially PAH (polycyclic aromatic hydrocarbons), PCB (polychlorinated biphenyls), PCDD/PCDF (dioxins and furans). Heavy metals and other inorganic substances, especially arsenic, cadmium, lead, chromium, copper, nickel, mercury, thallium, zinc.
Is burdened by pollutants?
When exposed to pollutants, infections and diseases can occur more frequently. These include allergies, intestinal, liver and kidney damage, respiratory, lung and cardiovascular diseases, cancer and neurological and mental disorders.
What are natural pollutants?
Natural pollutants are naturally formed substances that are formed in the plant to ward off predators such as insects or birds, diseases and pests.
Which pollutants pollute our water?
heavy metals. Lead, cadmium, mercury and other heavy metals can be found in fertilizers used in agriculture. In the event of flooding or with the groundwater, these harmful substances can be washed into rivers and bathing lakes.
What are the causes of pollutants in water?
The main source of nitrate is agriculture. Nitrate gets into the groundwater, particularly as a result of factory farming and the associated liquid manure. The fertilizers used in industrial agriculture also contribute to the soil – and thus the groundwater – being enriched with nitrate.
