This was a genre of wood that was highly valued in all of Europe. They started to deforest the atlantic forest of brazil to sell all the brazil wood in the markets in europe and asia. This deforestation continued and eventually reached areas all around the world, including South Africa. Many things have changed in the South African rainforest due to deforestation. Tropical rainforests are rapidly disappearing in a way that will greatly have an impact on planet earth.
The issue our group chose was the deforestation of the Amazon in South America. We chose this topic because we felt like its important and it is an issue that we need to try to put a stop to or decrease dramatically because it has many negative effects to the animals, the earth, the atmosphere, ecosystems, natural habitats,
Give details about the sources, time scale, and types of change. The biggest change that is happening in Madagascar that is posing challenges to Lemurs in Madagascar is the deforestation of the rain forest. The reason this is a challenge is it disrupts the economic system, its home, and the food supply. The Tropical Rain Forest is the Biomes in Madagascar. There is no real 0domination of one particular species in the Rain Forest and the Trees are typical evergreen trees.
About 90% of the animals living in the rain forest are adapted to living in the canopy (middle story) and there is an abundant variety of reptile, insect and amphibians living under then canopy. 2. What changes happening in Madagascar are posing challenges for lemurs? Give details about the sources, time scale, and types of change. Environmental changes are occurring, such as deforestation.
b) Candelabra Tree (_______ ) 1. Seeds are harvested in vast amounts and edible 2. Large food source for animals in the Savanna c) Elephant Grass 1. Favorite food of _________________ 2. Also harvested and burned to be used in _______ _ Plants C. Plant Functions a) Plants in the Savanna regions are highly specialized to grow in this region during long periods of drought b) They have long tap roots that can reach the deep water table, thick bark to resist forest fires, trunks that can store water, and leaves that _______ off during the winter to conserve water.
Australia has recently signed to Kyoto Protocol which aims to reduce greenhouse gas emission by 4 million tonnes becoming 2010. Companies have improved scrubbers, which clean sulfur from the smoke before it leaves the smokestack. Awareness is growing when considering pollution from coal. Here in Australia while we are monitoring carefully the atmospheric pollution caused by coal burning it can be stated categorically that Carbon dioxide emissions from vehicles have far more reaching effects than the pollution created from coal. Coal will continue to be used extensively in Australia because of it's abundance.
The mountain pine beetle epidemic is causing environmental and social impacts to much of British Columbia. Our forests are very important and will no longer be able to maintain their role if changes are not made. The devastation has had a sweeping impact on B.C.’s ecological, and economical well-being. Additionally, recent studies are drawing attention to the carbon-emitting properties of the dead forests, which is a global concern. A popular misconception developed that the current provincial mountain pine beetle epidemic began in Tweedsmuir Provincial Park.
Not only is the beetle epidemic killing off the ecosystem for the Grizzly Bears, it is also contributing to this little problem we keep hearing about on the news, and by Politian’s, Global Warming. We hear about it all the time, witness its effects every season, but some people still don’t believe it. The way that the Pine Beetle is affecting Global Warming is that it is changing the lush green pine forest into brown dead zones that are releasing carbon into the atmosphere. The Pine Beetle outbreak is actually threatening the balance of carbon in the region (Ira Platow 1). Carbon is a greenhouse gas, this means it has heat trapping features so it retains heat from the sun and gradually heats up the
This would be terrible for the people and creatures that rely on this mighty river to live. Dams, diversions and evaporation losses from reservoirs also contribute to the lessening of water available from the river, causing ecological consequences to wildlife living in and along the river. The Colorado River used to carry up to 85 to 100 million tons of silt or sediment to the Gulf of California where it deposited into the sea. The sediment helped things along the river path grow and flourish. Over the years, the silt has been collecting in Lake Mead, the nation’s largest reservoir, and it is predicted that over the next few hundred years this lake will fill up with silt.
Deforestation results from the removal of trees without sufficient reforestation (the replacement of trees). As a whole, deforestation reduces biodiversity, which is the variation of life forms, and negatively impacts the climate and geography not only in the United States, but also around the world. Some of the problems that need to be acknowledged range from forest fires to the lack of national policies
