Intro: Fresh Water can be found in lakes, rivers, swamps, ponds, streams, glaciers, icebergs etc. Fresh water is a renewable resource, yet the world's supply of groundwater is decreasing. Water replenishes itself through rain, fresh water is renewable but, is it not infinite.
We are very dependent on freshwater, it is an essential to life. More than 100,000 species rely on freshwater ecosystems. The importance of clean and healthy freshwater ecosystems is mandatory for a thriving planet. Many freshwater animals are becoming endangered and their populations are decreasing because of freshwater becoming polluted and altered by dams. Some of the animals that are becoming endangered are the amazon river dolphin, freshwater turtle, snow leopard and Mekong giant freshwater fish.
Water is used for many things, it is used for farming, industry, and for home drinking, washing, and watering. Most of Fresh Water is used in farming and agriculture. Water is mostly found as a liquid, it can also be a gas (water vapor) or a solid (ice). Fresh water for drinking comes from rivers, lakes, creeks, and dams. 97.5% of water is salt water and 2.5% is freshwater. 70% of freshwater is frozen in polar ice-caps, 30% lies underground and less than 1% of freshwater is available for human consumption.
Intro: Canada’s forests will be affected in a range of complex ways because of the changing climate. The rapid climate change Will affect tree growth rates, mortality rates, disturbance patterns and the distribution of tree species after disturbances. Impacts will be growing and interconnected, for example insect damage can increase the risk of wildland fires occurring; and drought can stress trees, making them more likely to be attacked by insects and disease. Due to recent climate changes Scientists have already documented changes in our forests
- the major infestation by mountain pine beetle
- increased fire activity in the western boreal forest
- increased aspen dieback in the Prairies
Even the study of cyclic and seasonal natural occurrence of trees in Canada’s forests appears to be changing, with earlier arrival of spring weather and longer summers affecting the timing of dormancy, leafing out, flowering and seeding. If the pace of climate change accelerated or even continued as it is today scientists have suggested:
Intro: Transport Canada's vision is a transportation system in Canada that is recognized worldwide as safe and secure, efficient and environmentally responsible. There are some important issues I want to solve with Canada’s transportation. Starting with the bus stops. There is very little and poor lighting. Especially in the winter and autumn with the early darkness it is making young people who are traveling in a dangerous situation. With it being that dark how can you spot a trouble maker.
Secondly there is very little sitting area, most people have to stand or wait outside the stop because it is small and gets crowded. Also there is almost never a garbage can near the stops, which is why the stops are always surrounded by garbage and waste creating an unsanitary environment. The growth population is growing and so is the demand for better transportation. If we want transportation like buses and trains to be sustainable, we will have to solve these issues by 2041, because the demand for better transportation will only grow.
