Презентация исследовательской работы по английскому языку на тему Человек — дитя природы (подготовили: группа ребят 11 класса)

Man- the child of natureEcological-problems What is the best way to save endangered animals? The number of endangered animals is constantly rising and there is no magic formula that could save these species from going extinct. The best way to save endangered animals from going extinct is to identify key factors that threaten their survival. In most cases the key threats to animal survival are humans, or to be more precise the human activity. Ocean acidification – A huge threat to algae Due to increased levels of carbon dioxide (CO2) in the atmosphere our oceans are becoming more and more acidic. Ocean acidification, despite not being mentioned in public as much as climate change and pollution is nonetheless a huge threat for marine environment, and if the acidity in our oceans continues to grow, algae will be among creatures most affected by it. Huge decline of amphibians is a major threat to global biodiversity Many amphibian species are at the brink of extinction. The decline of amphibians is happening in all corners of the world and scientists still do not fully understand the reasons behind such excessive population loss. There could be many different causes behind the decline of amphibians such as habitat loss, environmental pollution, invasive species, predation, reproduction, disease and of course the ever present climate change. What is science is right about climate change? There are still many climate change skeptics in the world who believe that science is wrong about climate change. Is it really so easy to remain ignorant about the most serious environmental threat of our time? If we believe science about so many different things then why not believe in what they have to say about climate change? Why would scientists lie to us? If science is right about climate change then our children and our grandchildren will have a really tough time surviving in future world. Almost all predictions about the future climate are about dramatic changes characterized by frequent extreme weather events, major sea level rise, new diseases, floods, droughts, etc. Definitely not something to looking forward too. Environmental protection is of a universal concern. That is v/hy serious measures to create a system of ecological security should be taken. Some progress has been already made in this direction. As many as 159 countries - members of the UNO - have set up environmental protection agencies. Numerous conferences have been held by these agencies to discuss problems facing ecologically poor regions including the Aral Sea, the South Urals, Kuzbass, Donbass, Semipalatinsk and Chernobyl. An international environmental research centre has been set up on Lake Baikal. The international organisation Greenpeace is also doing much to preserve the environment. But these are omy the initial steps and they must be carried onward to protect nature, to save life on the planet not only for the sake of the present but also for the future generations. Every year world industry pollutes the ahmosphere with about 1000 million tons of dust and other harmful substances. Many cities suffer from smog. Vast forests are cut and burn in fire. Their disappearance upsets the oxygen balance. As a result some rare species of animals, birds, fish and plants disappear forever, a number of rivers and lakes dry up.The pollution of air and the world's ocean, destruction of the ozone layer is the result of man's careless interaction with nature, a sign of the ecological crises.The most horrible ecological disaster befell Ukraine and its people after the Chernobyl tragedy in April 1986. About 18 percent of the territory of Byelarus were also polluted with radioactive substances. A great damage has been done to the agriculture, forests and people's health. The consequences of this explosion at the atomic power-station are tragic for the Ukrainian, Byelarussian and
