2. How Humans Affect The
Ecosystems In a Negative way?
 Human impact on the ecosystem is something
done by humans and gives the affect at the
ecosystem like chopping down forests,and cars
burning off greenhouse gases.Humans can
effect the ecosystem in a negative way ,by
pollution, waste dumping, over hunting of
animals,over fishing,industrial gases,energy use
and not using biodegradable products.

3. Deforestation
 Population growth leads to
the loss of natural
habitats.
 Cut down trees to build
new homes
 Loss of biodiversity
 Loss of oxygen producers
and CO2 eliminators

4. Population growth leads to;
 Burning fossil fuels
 Non-renewable resources
 Pollution
 Increase co2 levels
Industrialization

6. Global warming
 Increase in co2
 Increase in green house effect
 Increase in global temperatures

8. Air pollution
 Air pollution is a mixture of solid particles and
gases in the air. Car emissions, chemicals
from factories, dust, pollen and mold spores
may be suspended as particles. Ozone, a
gas, is a major part of air pollution in cities.
When ozone forms air pollution, it's also
called smog.

10. Habitat Destruction
 Habitat destruction occurs when
natural habitatsare no longer able to support
the species present, resulting in the
displacement or destruction of its
biodiversity. Examples include harvesting
fossil fuels, deforestation, dredging rivers,
bottom trawling, urbanization, filling in
wetlands and mowing fields.

Thank you

13. Water pollution
 Water pollution is
the contamination of water bodies (e.g.
lakes, rivers, oceans, aquifers and
groundwater). This form of environmental
degradation occurs whenpollutants are
directly or indirectly discharged
intowater bodies without adequate treatment
to remove harmful compounds.
