Слайд 2
Biodiversity is defined as the set of all living organisms and

species on land and all natural things around them such as: oceans, rivers, mountains, deserts, land, forests, jungles, animals, plants, atmosphere, heaven and humans. Climate change: climate change is affecting biodiversity so that this becomes a major threat to biodiversity in the coming decades. Since this originated Although throughout the history of the Earth climate has always changed with the ecosystems and species that came and went, rapid climate change affects ecosystems and the ability of species to adapt and thus increases the loss of biodiversity. While the loss of biodiversity increases the life of humans at risk enters e.g. climate change can dry the water taking into account global warming, and if no water, no human, this would also affect plants as without water, photosynthesis cannot be performed, also with animals and plants not animals without human life disappears. So if biodiversity has this enormous threat we are under this threat also already there are evidence of how species are responding to global warming.


Слайд 3Why biodiversity is important?
Life has been able to adapt to the

most diverse places on earth, from microscopic creatures that habit in the icy landscapes of the poles to creatures that live in warmer places, since the birds that fly at high altitudes than fish living in depths of the ocean, our planet is full of living organisms. All of them are part of the history of the world in the last 3.5 billion years, which means since the onset of the first cell. Just the study of early life forms, has allowed us to see how they have evolved from the simplest of bacteria to the most complex. And even though we all know that in reality we are only able to identify with a name 10 percent of them, the remaining 90 percent are still a mystery to humans.


Слайд 4Climate change linked to human activity
In the world, human activities have

caused and will continue causing wear on biodiversity due to, among other things, changes in use and surface soil, pollution and land degradation and air pollution; the diversion of water into heavily altered ecosystems and urbanization’s, environmental decay, exploitation of species, introduction of alien species, ozone depletion and weather. The current rate of biodiversity loss is greater than the natural extinction. A fundamental question is how much can change (either natural or human-induced) increase or prevent such loss of biodiversity? The changes in climate create a secondary alteration to biodiversity that has begun affecting it. Atmospheric concentrations of greenhouse gases have increased since preindustrial times due to human activities, particularly fossil fuels and changes in use and on the surface of the soil.


Слайд 5Loss of species by climate change
The extinction of species increases the

biodiversity loss, and with them our existence. For example: bees are disappearing, disappear. The consequences are disastrous this can cause the pollination is what has made it possible for millions of years, to ensure the reproduction from the plant to flower. In addition, 35% of our diet depends on pollination: fruit and vegetables. The most famous food recommended by dieticians. Moreover, in certain regions of the world, the disappearance of pollinating insects forces from Polish farmers to pollinate by hand. Researchers and beekeepers are moving in different scenarios, it has not yet been clearly identified the main cause of the extinction of bees. All pressures on the ecosystem and the health of bees have been revised: GMOs, electromagnetic waves, pesticides, pollution, climate change, scarcity of flowers, viruses, diseases, parasites.


Слайд 6Conclusion
As I explained earlier biodiversity plays a very important in us

as this is vital for human life, and this is being eroded by many factors, but here in this project. Mainly I just said the climate change, we cause rapid climate change which becomes a threat to biodiversity, bone for us, but we can do something to prevent it? Yes, there are many things you can do to help or participate in improving the current condition of the Earth and future conditions are: Improving the efficiency of cars. Be achieved through better technology, lightening the structure, improvements in engines and transmission, reducing aerodynamic drag, decreasing resistance of the wheels, etc. Accelerate improvements in energy efficiency of industries, residences and commercial establishments and public, through effective policies. Stimulate and accelerate research and development of technologies based on energy sources of renewable energy. Ending deforestation and encourage reforestation
