Mexico´s Ecosystem

In Mexico we have a lot of different plants and animals. Mexico´s flora (plants) is bigger than USA and Canada´s together, and it´s twice as big as the flora in Europe. The fauna are the animal species. Mexico has the biggest number of reptiles in the whole world. The second in mammals, the 4th in amphibians and the 7th in birds. This great diversity of flora and fauna it´s thanks to the different climate and territory, such as mountains, Cliff, coast, caves, etc.A species it´s a group of animals or plants that share the same characteristic. If we change ecosystems in a negative way we affect many species of animals that are in danger of extinction. Also earthquakes, climate changing, volcanoes, etc are natural changes in ecosystems that affect animal species.
Some of human action that affect ecosystems and the extinction of some species:

1. The growth of cities.

2. Pollution

3. Cutting trees.

4. When we move species from the original ecosystems, for example the cactus from the north of Mexico and Oaxaca.

5. Fishing and hunting.

6. Illegal hunting.
