Sugarcane cultivation takes up only 2.5% of the total agricultural land available and it has been predicted that there is plenty of potential for agricultural expansion (Padula et al, 2007). It is well accepted that, in Brazil, the current large-scale sugarcane production does not compromise food production, and even an expansion would be possible without constraints. Sugarcane is mostly cultivated in the southeast region of Brazil and sugarcane production has limited impact on deforestation, because the soil and weather conditions in the Amazon are not suitable for sugarcane. Nevertheless, large areas dedicated for sugarcane production limit the land availability that can be used for other crops. In areas, where sugarcane is primarily produced, the production of oranges, cattle and other crops have lost space to sugarcane (Padula et al. 2007; Bowen, 2010). 3.4. Soybean and rapeseed oil
Renewable energy Meriliin Lend Estonian University of Life Sciences Tartu 2013 Topics Renewable energy Solar energy Wind energy Hydroelectric power Geothermal energy Biomass energy Renewable energy Renewable energy comes from sources that naturally renew, or will not run out in our lifetimes. Includes sunlight, wind, water, geothermal heat and various forms of biomass. Renewable energy cannot be exhausted and is constantly renewed. Does not harm the environment. Saves money. Solar energy Solar energy is the technology used to harness the sun's energy and make it useable. Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year. Solar energy use has surged at about 20 percent a year over the past 15 years, thanks to rapidly falling prices and gains in efficiency. Solar energy is inexhaustible. Noise free.

grown on the African oil palm tree. Oil palms are originally from Western Africa, but can flourish wherever heat and rainfall are abundant. Today, palm oil is grown throughout Africa, Asia, North America, and South America, with 85% of all palm oil globally produced and exported from Indonesia and Malaysia; but most of the time not using sustainable measures. The industry is linked to major issues such as deforestation, habitat degradation, climate change, animal cruelty and indigenous rights abuses in the countries where it is produced, as the land and forests must be cleared for the development of the oil palm plantations. According to the World Wildlife Fund, an area the equivalent size of 300 football fields of rainforest is cleared each hour to make way for palm oil production. This large-scale deforestation is pushing many species to extinction, and findings show that if nothing hanges, species like the

threaten the well being of humans. FIND OUT 5 WAYS HOW TO MANAGE WASTE. 5. Loss of Biodiversity: Human activity is leading to the extinction of species and habitats and loss of bio- diversity. Eco systems, which took millions of years to perfect, are in danger when any species population is decimating. Another example is the destruction of coral reefs in the various oceans, which support the rich marine life. FIND OUT 5 WAYS HOW TO HALT THE LOSS OF BIODIVERSITY 6. Deforestation: Our forests produce fresh oxygen and help in regulating temperature and rainfall. At present forests cover 30% of the land but every year tree cover is lost amounting to the country of Panama due to growing population demand for more food, shelter and cloth. Deforestation simply means clearing of green cover and making that land available for residential, industrial or commercial purpose. FIND OUT 5 WAYS HOW TO STOP DEFORESTATION. 7
Some scientists still do not think that the effects of global warming are as severe as some people say. They think that droughts, hurricanes, and floods often blamed on global warming might actually have other causes. One major difficulty in studying global warming is the fact that weather data only exists for the last century and a half. As a result, understanding the present and predicting the future are very difficult. Rain forest destruction The atmosphere and oceans are not the only parts of the environment being damaged. Rain forests are being quickly destroyed as well, and their survival is questionable. E.O. Wilson, a biologist at Harvard, called the depletion of rain forest areas "the greatest extinction since the end of the age of dinosaurs." Unlike some environmental issues, rain forest depletion has fortunately received significant public and media attention.

The Pacific Coast - The Cordillera Bathed by warm Pacific air currents, the British Columbia coast, indented by deep fiords and shielded from the Pacific storms by Vancouver Island, has the most moderate climate of Canada's regions. Vancouver Island's west coast receives an exceptional amount of rain, giving it a temperate rain forest climate. Although it does not contain the diversity of species of a tropical rain forest, the island's west coast does have the oldest and tallest trees in Canada: western red cedars 1,300 years old and Douglas firs over 90 metres high. Canada, Kärt Kalvet 8a From British Columbia to just east of the Alberta border the land is young, with rugged mountains and high plateaus. Signs of geologically recent volcanic activity can be seen in Garibaldi Provincial Park in southern British Columbia and at Mount Edziza in the north.
