Major+Environmental+Concerns

Major Environmental Concerns.

 1. Land Degradation. Land can be ruined by human activities. If we do not look after the land we will struggle to have enough resources, such as food, for everyone to be able to survive.
 * Everything we have and need comes from the land
 * People damage and degrade the land in lots of ways
 * Erosion is when the soil is blown or washed away
 * Salinity causes major damage to the land
 * Feral animals are harmful to the land
 * Tasmania's rainforests are being cleared for a variety of purposes

 2. Marine and Coastal Degradation. The oceans and coast are showing the effects of human activity. Pollution and over-fishing, in particular, are having a serious effect on the ocean and coast ecosystems.  3 .Pollution = Pollution and Climate Change.All human activities have an effect on the environment. The biggest threat to our current way of life is pollution and climate change. We must work toward changing the way we use the Earth's resources so that we cause less damage to the environment. =
 * The ocean's resources are not inexhaustible
 * The ocean and beaches are becoming more and more polluted
 * Commercial whaling has been banned but some countries are still hunting small numbers
 * <span style="display: block; font-family: "Comic Sans MS",cursive; font-size: 130%; text-align: left;">Many species of fish are being over-fished

<span style="font-family: "Comic Sans MS",cursive; font-size: 90%;">A consequence of human activity is waste. What to do with this waste is a major problem for the world today.One solution is to recycle as much as we can so that the amount of waste is reduced <span style="display: block; font-family: "Comic Sans MS",cursive; font-size: 130%; text-align: left;"> 5 .Water Management Without water nothing can live. Only 0.03 percent of all the water on Earth is available for drinking, washing and growing food. The oceans make up 97 percent of the Earth's water and 2.97 percent is locked up in the icecaps. We are using more water than ever before. About 70 percent of the water is used for farming and irrigation, 23 percent is used in industry and energy generation and seven percent is used in households, gardens and swimming pools. A lot of our drinking and household water comes from under ground, from aquifers or artesian basins. The water in most of these basins and aquifers is being used faster than it is being replaced.

 * <span style="font-family: "Comic Sans MS",cursive; font-size: 130%;">Everything that people throw away is called waste
 * <span style="font-family: "Comic Sans MS",cursive; font-size: 130%;">There is household, industry and mining waste
 * <span style="font-family: "Comic Sans MS",cursive; font-size: 130%;">Landfill or burying rubbish is the main way to dispose of our waste
 * <span style="font-family: "Comic Sans MS",cursive; font-size: 130%;">Toxic (poisonous) waste may escape from a landfill into the environment
 * <span style="font-family: "Comic Sans MS",cursive; font-size: 130%;">Recycling is one of the best ways to reduce our waste
 * <span style="font-family: "Comic Sans MS",cursive; font-size: 120%;">Water is a vital resource that is easily polluted and wasted
 * <span style="font-family: "Comic Sans MS",cursive; font-size: 120%;">Many of rivers in Australia and the world are being damaged
 * <span style="font-family: "Comic Sans MS",cursive; font-size: 120%;">Our rivers and waterways have to be carefully managed to keep them healthy
 * <span style="font-family: "Comic Sans MS",cursive; font-size: 120%;">Humans are consuming more water than ever but we need to manage this resource more carefully so that there will always be enough freshwater available for our needs.
