GLOBAL ISSUES


What needs to be done? After a family has one child a family will be taxed if they have more kids.

How do u plan to accomplish it? We will allow the countries governments to kepp the tax money so they will be more likely to except the law

Who will be responsible for oversight? The UNFPA will be responsible for for over seight

How will the solution be funded? We will make the familys pay there governments if they have more than one kid

The solution will be monitored by seeing how much tax money each government gets and dividing it by how much each taxed kid costs so we can see if berth rates are reducing

The consequences for non-compliance will be taxation and if the familys cant offord to pay for the children they had it will be sent into foster care

Climate Inquiry

1. The atmosphere has a natural supply of "greenhouse gases." They capture heat and keep the surface of the Earth warm enough for us to live on. Without the greenhouse effect, the planet would be an uninhabitable, frozen wasteland. Industry took off in the mid-1700s, and people started emitting large amounts of greenhouse gases. Fossil fuels were burned more and more to run our cars, trucks, factories, planes and power plants, adding to the natural supply of greenhouse gases. The gases—which can stay in the atmosphere for at least fifty years and up to centuries—are building up beyond the Earth's capacity to remove them and, in effect, creating an extra-thick heat blanket around the Earth.
The result is that the globe has heated up by about one degree Fahrenheit over the past century—and it has heated up more intensely over the past two decades. Already, people have increased the amount of CO2, the chief global warming pollutant, in the atmosphere to 31 percent above pre-industrial levels. There is more CO2 in the atmosphere now than at any time in the last 650,000 years. Studies of the Earth’s climate history show that even small changes in CO2 levels generally have come with significant shifts in the global average temperature.

Earth's water cycle has been pushed to its limit. The amount of water evaporating off the land and into the atmosphere hit a maximum 12 years ago and is now in decline, new calculations show.
Martin Jung of the Max Planck Institute for Biogeochemistry in Jena, Germany, and colleagues calculated trends in evapotranspiration – the amount of water vapour that entered the atmosphere – between 1982 and 2008. This moisture is either evaporated off the land by the sun's heat or released by plants.
They found that evapotranspiration rose steadily until 1998, as would be expected in a warming global climate. But the trend reversed in 1998, and the amount of moisture being cycled into the atmosphere began to drop.
Team member Steven Running of the University of Montana in Missoula says that in some regions, rising temperatures have sucked all the available water out of the ground. Though that moisture returns to the ground as rain, most of it falls elsewhere, leaving dry regions like Australia parched.

1. i learned alot about the sewer treatment plant this last week when i visited it. i learned that there are several steps to sanitize or water that comes from all the city toilets and sinks. The trash and garbage that comes from the garbage disposal is all cought in a big machine and broken down. a fun fact for you is that 99.9% of the water that comes to the plant is already clean, its that .1 percent that has poop and garbage in it. another thing is the water is put into a big tank that pumps oxygen in to it. this allows for the healthy microrganisms to eat the dirty junk in the water that dosnt need to be there. then the water goes into another tank wich allows the solids to settle to the bottom and be takin out.

 2. recycling is important, if we bought a 24 pack of pop and threw all the cans away that would be dumb, so why not recycle them and make 24 new cans. you can also recycle medals and and plastics. so instead of us keep taking raw materials out of the earth we can keep recycling and save the earth! i will continue to receycle because because i like getting money after i have alot of cans, and its good for our enviroment.

City talk

1. Her name was Mrs byerly. She worked for the city of eaton rapids, and she came and talked to our class.

2. The city upgraded the sewer water treatment system by putting in bigger storm drains and rain gardens to help prevent stuff from getting into the river when it rains. Wich well help with a good chunck of pollution because the rain water will take all the debre from the streets and it will go rite into our river.

3. Adding the storm drain and the rain gardens will help the river alot. It will keep chemicals like oil and metals that come off of our cars and into the environment. exspecially the roadways and parking lots the improvments should keep our river cleaner.
4. My group was responsible for the temperature of the river. the improvments wont really help with the tempature of the water but it will help with other things wich is still good.

5.  The thing i found the most interesting was the irony. because with putting these new roads in and all the chemicles and debre coming from the heavey equipent then it going into our river and polluting it. so when the construction is gone our river will become a little cleaner.

6. my bio bottle is improving dailey. our grass is getting tall and our peas our getting bigger. some of the plastic in one of our expirments is keeping the grass and peas from growing. wich is proving that plastic is bad for our enviroment so our bio bottle lab is pretty sucsessfull.

7. As a group we havnt really gave eachother rolls yet, but we will each be contibuting.

8. We have not started our lexus power point yet because we still gathering data
