2 Forestry facts 2-3 % of forests are lost each year globally 2-3 % of forests are lost each year globally 60% of the benefits that the global ecosystem provides (water, clean air, stable climate) are being degraded or used 60% of the benefits that the global ecosystem provides (water, clean air, stable climate) are being degraded or used

3 Deforestation Causes: Causes: Cattle raisingCattle raising Agriculture or urban developmentAgriculture or urban development Due to population boom Due to population boom Effects: Effects: Spread of infectious diseases Interruption of ecosystem Erosion of soil

4 Deforestation and Wildlife Tropical forests cover 7% of the earth’s dry land but shelter about half of the world’s species Tropical forests cover 7% of the earth’s dry land but shelter about half of the world’s species Decreases habitat for wildlife speciesDecreases habitat for wildlife species Extinction or Displacement Extinction or Displacement

7 A Solution to Deforestation Environmental issues effect everything on this planet from the smallest bacteria to human beings. Environmental issues effect everything on this planet from the smallest bacteria to human beings. Life on Earth is a balance between it’s natural settings and the way we treat it. Life on Earth is a balance between it’s natural settings and the way we treat it. It is certain that finding the ultimate solution for deforestation is difficult, but if everyone contributes it will benefit the Earth in tremendous ways.

8 A Solution to Deforestation Reforestation Earth day Earth day Is a day that marks the first day of spring and to show a global appreciation to Earth in hopes to carry out this thought for the rest of the year.Is a day that marks the first day of spring and to show a global appreciation to Earth in hopes to carry out this thought for the rest of the year. Paulownia & The Environment (tree farms) Paulownia & The Environment (tree farms) Paulownia lumber is farmed on plantations rather than taken from old forests. It’s alternative to other hardwoods that can be found in the jungles and rain forests.Paulownia lumber is farmed on plantations rather than taken from old forests.

9 Solar Alternative in Wood scarce areas Families in most parts of the world each consume about 3 tons of wood. Families in most parts of the world each consume about 3 tons of wood. In much of Africa desertification is a risk and wood is scarce. In much of Africa desertification is a risk and wood is scarce. Solar cookers use energy from the sun to cook food.

The world already produces enough calories for everyone but it is distributed unevenly: The world already produces enough calories for everyone but it is distributed unevenly: 70% of grain grown in the US and Canada is feed to cattle, not hungry people.70% of grain grown in the US and Canada is feed to cattle, not hungry people.

11 Problems in Farming Farmland is not being used efficiently, and uncultivated or abandoned arable land is increasing. These are due to inadequate efforts to increase principal farmers, and a lack of progress in producing feed crops through collaboration between crop and livestock, farming, among other reasons.

13 Actions * Promoting consumption of rice and other domestic agricultural produce. Ensuring a stable supple of food –taking into account the whole food chain Ensuring a stable supple of food –taking into account the whole food chain Promoting food education aimed at achieving ideal diets Promoting food education aimed at achieving ideal diets Promoting local consumption of local produce Promoting local consumption of local produce Securing the stability of food imports and food security in emergencies Securing the stability of food imports and food security in emergencies Supporting and recruiting farmers to establish an ideal agricultural structure Supporting and recruiting farmers to establish an ideal agricultural structure

14 Genetically Modified GM Genetically modified food is produced from plants which have had their genetic make up tweaked in the lab. This can allows the plant to exist in a more hostile environment than normal. GM Genetically modified food is produced from plants which have had their genetic make up tweaked in the lab. This can allows the plant to exist in a more hostile environment than normal. Controversial? The modified crops could “escape” and cross with wild plants, with unknown consequences. Controversial?

Benefits: GM crops can be enriched with nutrients and they can produce bigger yields and therefore can use farmland more efficiently.

19 Solving the problem Smart Growth (Urban Consolidation) Smart Growth (Urban Consolidation) Land rationing Extravagant Amenities Excessive infrastructure fees Approval processes The culture of control Housing Affordability Housing Affordability The question of how God would have us live with what we have is one that will have to be answered because no human solution can adequately address the problems that we will face with growing cities and the depleting natural resources.
