Слайд 2What tropical forests are..
Tropical rainforests-forests distributed in the tropical, subequatorial
and equatorial zones.
There are 2 classifications of tropical forests: tropical
rainforests and seasonal rainforests

Слайд 3Tropical rainforests
Tropical rainforests — located in the equatorial belt.
A
lot of precipitation falls there (2000–7000 mm)
The climate is
hot, the air temperature is 24–28 ° C.
Tropical rainforests are very ancient, with them began the formation of many species living on earth.
The main subgroups of tropical rainforests are: evergreen mountain forests, tropical swamp forests, rain tropical lowland forests, mangroves.
Слайд 4Seasonal rainforests
Seasonal tropical forests — located in arid areas, although
there are also a lot of rainfalls.
The duration of
the dry period is different in seasonal forests .
There are 3 groups of seasonal tropical forests: evergreen seasonal forests, semi-evergreen forests, light sparse forests.
Deciduous seasonal tropical forests are divided into monsoon forests and savanna forests
Слайд 5The location of rainforests
The main regions of distribution: South America,
Central Africa, Southeast Asia and Australia
Слайд 6Main characteristics
Humid rainforests are very rich in vegetation. Nowhere else
you will find so many kinds of trees. Each tree
can have a different height and bark, even the emergent. In swamp forests there are more palm trees, in humid tropical forests are common tree ferns, the first plants that appeared on our land. These plants allow humanity to live, filling our atmosphere with oxygen. They make a difference, but not everyone understands this.
Слайд 7As a rule, tropical forest animals live on trees. Mammals
are monkeys, flying squirrels, some insectivores, predators, and so on.
Birds are parrots, toucans and others. Chameleons and iguanas are examples of reptiles. Due to the lack of light, the undergrowth is poor, therefore there are few terrestrial species in them. The habitat of large mammals: elephants, giraffes, buffaloes, here are in seasonal tropical forests.
Слайд 8Tropical forests are important for the biosphere of the planet
Tropical
forests are important for the biosphere of the planet. As
I have already said, most earth species of plants live in tropical forests. (The area of tropical forests is half the forest territory of the Earth)
Слайд 9Tropical forests release a huge amount of oxygen per year.
Tropical
forests evaporate about 9% of the water entering the atmosphere.
They
produce 69% of all pure primary production of the world's forests.
Слайд 10Threats to tropical forests
The most terrible thing for the forests
is their cutting.
Also, over time, forests lose their greatness,
because the climate on the planet changes, and tropical forests turn into a deserts.
People are also a problem for the forests, like poachers. I believe that the wildlife of tropical forests should be respected and protected by all people.
Слайд 11Of course, there are special organizations that protect nature and
search solutions of issues of global warming and environmental pollution.
UNEP-It
plays an important role in the development of international relations in the field of ecology and environmental protection.
IUCN-international organization dedicated to covering the problems of the conservation of biodiversity of the planet
