2. Use of Chemical Pesticides
Which includes pesticides such as insecticides, herbicides, and fungicides. Pesticides
are actually only used to kill disturbing organisms (pests), in fact they spread to the
environment and poison microbes, fungi, animals and other plants.

3. Pollution
Pollutants can also kill important microbes, fungi, animals and plants. Pollutants can
come from factory waste and household waste.

4. Changes in Plant Type
Plants are producers in the ecosystem. Changes in plant types such as changes from
tropical rain forests to production forests can result in the loss of important wild plants.
The loss of certain types of plants can cause the loss of animals that live depending on
these plants.

5. Entry of Wild Plants and Animals
Wild plants or animals that enter the ecosystem can compete and even kill native
plants and animals.

6. Selection
Our behavior inadvertently accelerated the extinction of organisms. For example, we
often only plant plants that we think are superior, for example gadung mango,
manalagi mango, bangkok guava. On the other hand, we eliminate plants that we think
are less superior, for example mango golek, guava.

7. Fragmentation and loss of habitat
Construction of dams, development of coastal areas, extensification of agriculture,
logging.

8. Species Introductions
Namely efforts to bring foreign species into an area that already has local species.

9. Exploitation of excess animals and plants
For example, the use of superior rice causes the extinction of traditional rice.

10. Global Climate Change.
Air pollution causes an increase in the earth's temperature. Each 1 ° C increase will
replace the tolerance limits for some species on land about 125 km toward the poles or
150 m vertically up the mountain. Sea levels will rise and some islands will sink.

11. Agricultural and Forestry Industrialization
Plant breeding causes a monoculture planting system so that the biodiversity in an area
decreases.
